`org.codehaus.jackson` is an older version of Jackson. 

`com.fasterxml.jackson` represents the new project and package. 

The reason is, Jackson has moved from Codehaus to Github when releasing Jackson 2. 

See [here][1] for details.

I would recommend removing `org.codehaus.jackson` references from your POM, re-building and looking for errors (not likely but possible). 

If you find any, you can adapt the code using deprecated API to the newer Jackson version&#39;s API.

I came across a javascript library that uses the following syntax to import libraries:

    import React, { Component, PropTypes } from &#39;react&#39;;

What is the difference between the above method and the following?

    import React, Component, PropTypes from &#39;react&#39;;

I am pretty new to Go and don&#39;t quite understand everything as yet. In many of the modern languages Node.js, Angular, jQuery, PHP you can do a GET request with additional query string parameters. 

Doing this in Go isn&#39;t quite a simple as it seems, and I can&#39;t really figure it out as yet. I really don&#39;t want to have to concatenate a string for each of the requests I want to do. 

Here is the sample script:

    package main
    
    import (
        &quot;fmt&quot;
        &quot;io/ioutil&quot;
        &quot;net/http&quot;
    )
    
    func main() {
        client := &amp;http.Client{}
    
        req, _ := http.NewRequest(&quot;GET&quot;, &quot;http://api.themoviedb.org/3/tv/popular&quot;, nil)
        req.Header.Add(&quot;Accept&quot;, &quot;application/json&quot;)
        resp, err := client.Do(req)
    
        if err != nil {
            fmt.Println(&quot;Errored when sending request to the server&quot;)
            return
        }
    
        defer resp.Body.Close()
        resp_body, _ := ioutil.ReadAll(resp.Body)
    
        fmt.Println(resp.Status)
        fmt.Println(string(resp_body))
    }

In this example you can see there is a URL, which requires a GET variable of api_key with your api key as the value. The problem being that this becomes hard coded in the form of:

    req, _ := http.NewRequest(&quot;GET&quot;, &quot;http://api.themoviedb.org/3/tv/popular?api_key=mySuperAwesomeApiKey&quot;, nil)


Is there a way to build this query string dynamically?? At the moment I will need to assemble the URL prior to this step in order to get a valid response.

Are `org.codehaus.jackson` and `com.fasterxml.jackson.core` related?
I have 
       

&gt; org.codehaus.jackson  jackson-all version 1.7.2

 
and 
       

&gt; com.fasterxml.jackson.core &gt; jackson-databind version 2.4.3

in my `pom.xml`.
I am not sure if they are redundant and can conflict.

I&#39;m facing a problem when using Spring Security &amp;&amp; Thymeleaf, specifically when trying to use the [hasRole](http://docs.spring.io/spring-security/site/docs/4.0.1.RELEASE/reference/htmlsingle/#el-common-built-in) expression. The &#39;admin&#39; user has a role &#39;ADMIN&#39; but `hasRole(&#39;ADMIN&#39;)` resolves to false anyway I try it

My html:

    1.&lt;div sec:authentication=&quot;name&quot;&gt;&lt;/div&gt; &lt;!-- works fine --&gt;
    2.&lt;div sec:authentication=&quot;principal.authorities&quot;&gt;&lt;/div&gt; &lt;!-- works fine --&gt;

    3.&lt;div  sec:authorize=&quot;isAuthenticated()&quot; &gt;true&lt;/div&gt; &lt;!-- works fine --&gt;
    4.&lt;span th:text=&quot;${#authorization.expression(&#39;isAuthenticated()&#39;)}&quot;&gt;&lt;/span&gt; &lt;!-- works fine --&gt;

    5.&lt;div th:text=&quot;${#vars.role_admin}&quot;&gt;&lt;/div&gt; &lt;!--Works fine --&gt;
    6.&lt;div  sec:authorize=&quot;${hasRole(&#39;ADMIN&#39;)}&quot; &gt; IS ADMIN &lt;/div&gt; &lt;!-- Doesnt work --&gt;
    7.&lt;div  sec:authorize=&quot;${hasRole(#vars.role_admin)}&quot; &gt; IS ADMIN &lt;/div&gt; &lt;!-- Doesnt work --&gt;
    8.&lt;div th:text=&quot;${#authorization.expression(&#39;hasRole(&#39;&#39;ADMIN&#39;&#39;)&#39;)} &quot;&gt;&lt;/div&gt; &lt;!-- Doesnt work --&gt;
    9.&lt;div th:text=&quot;${#authorization.expression(&#39;hasRole(#vars.role_admin)&#39;)}&quot;&gt;&lt;/div&gt; &lt;!-- Doesnt work --&gt;

results in:

    1.admin
    2.[ADMIN]
    3.true
    4.true
    5.ADMIN
    6.&quot;prints nothing because hasRole(&#39;ADMIN&#39;) resolves to false&quot;
    7.&quot;prints nothing because hasRole(#vars.role_admin) resolves to false&quot;
    8.false
    9.false

I have enabled _use-expressions_ in my security.xml file

    &lt;security:http auto-config=&quot;true&quot; use-expressions=&quot;true&quot;&gt;

Spring Security hasRole() not working

In JDK8, how many threads are spawned when i&#39;m using parallelStream? For instance, in the code:

    list.parallelStream().forEach(/** Do Something */);

If this list has 100000 items, how many threads will be spawned?

Also, do each of the threads get the same number of items to work on or is it randomly allotted?

How many threads are spawned in parallelStream in Java 8?

Pattern matching in Kotlin is nice and the fact it does not execute the next pattern match is good in 90% of use cases.

In Android, when database is updated, we use Java switch property to go on next case if we do not put a break to have code looking like that:

    switch (oldVersion) {
        case 1: upgradeFromV1();
        case 2: upgradeFromV2(); 
        case 3: upgradeFromV3();
    }

So if someone has an app with version 1 of the DB and missed the app version with DB v2, he will get all the needed upgrade code executed.

Converted to Kotlin, we get a mess like:
   
    when (oldVersion) {
        1 -&gt; {
            upgradeFromV1()
            upgradeFromV2()
            upgradeFromV3()
        }
        2 -&gt; {
            upgradeFromV2()
            upgradeFromV3()
        }
        3 -&gt; {
            upgradeFromV3()
        }
    }

Here we have only 3 versions, imagine when DB reaches version 19.

Anyway to makes when acting in the same way then switch? I tried to continue without luck.

For the following `Period` calculation:

    Period.between(LocalDate.of(2015, 8, 1), LocalDate.of(2015, 9, 2))

the result is:

    P1M1D

This is equivalent to 31 days + 1 day = 32 days.

For this `Period`:

    Period.between(LocalDate.of(2015, 8, 1), LocalDate.of(2015, 10, 2))

the result is:

    P2M1D

This is equivalent to: 31 days (in August) + 30 days (in September) + 1 (in October) = 62 days

Is there a method in the `java.time` package which will give the number of days in a `Period`? I can&#39;t find one. Not sure if I have overlooked anything or if it is just plain not there.

The following does not compile, giving an &#39;illegal forward reference&#39; message:

    class StaticInitialisation {
    
    	static
        {
            System.out.println(&quot;Test string is: &quot; + testString);
        }
    
        private static String testString;
     
        public static void main(String args[]) {
            new StaticInitialisation();
        }
    }

However, the following does compile:

    class InstanceInitialisation1 {
    
        {
            System.out.println(&quot;Test string is: &quot; + this.testString);
        }
    
        private String testString;
     
        public static void main(String args[]) {
            new InstanceInitialisation1();
        }
    }

But the following does not compile, giving an &#39;illegal forward reference&#39; message:

    class InstanceInitialisation2 {
    
    		private String testString1;
    
        {
            testString1 = testString2;
        }
    
        private String testString2;
     
        public static void main(String args[]) {
            new InstanceInitialisation2();
        }
    }

Why do StaticInitialisation and InstanceInitialisation2 not compile, while InstanceInitialisation1 does?

Why do two programs have forward referencing errors while the third does not?

I&#39;m bashing my head against an error I can&#39;t work out how to fix.  I have the following;

JSON

    {&quot;products&quot;:

            }
        }
    ]}
and the following jQuery

    function getData(data) {
        this.productID = data.product_id;
        this.productData = data.product_data;
        this.imageID = data.product_data.image_id;
        this.text = data.product_data.text;
        this.link = data.product_data.link;
        this.imageUrl = data.product_data.image_url;

        var allProducts = data.map(function (item) {
            return new getData(item);
        });
    });

yet I&#39;m getting an error that map.data is undefined as a function?  Looking at it I don&#39;t know what&#39;s not working as I&#39;ve copied this to a new project from previously used code.  The only thing different is the JSON source.  The previous one didn&#39;t have the `{&quot;products&quot;:` part before the [] brackets.  Is this what&#39;s throwing me off?

data.map is not a function

Ok so I found this really well documented `node_module` called [js-xlsx][1]


**Question:**  How can I **parse an xlsx to output json**?


Here is what the excel sheet looks like:

Parse XLSX with Node and create json

My question is essentially a follow-up to [this][1] question.

    @RestController
    public class TestController
    {
        @RequestMapping(&quot;/getString&quot;)
        public String getString()
        {
            return &quot;Hello World&quot;;
        }
    }

In the above, Spring would add &quot;Hello World&quot; into the response body. How can I return a String as a JSON response?  I understand that I could add quotes, but that feels more like a hack.

Please provide any examples to help explain this concept.

&gt; **Note:** I don&#39;t want this written straight to the HTTP Response body, I want to return the String in JSON format (I&#39;m using my Controller
&gt; with [RestyGWT][2] which requires the response to be in valid JSON
&gt; format).

Spring MVC - How to return simple String as JSON in Rest Controller

I want to describe with JSON schema array, which should consist of zero or more predefined values. To make it simple, let&#39;s have these possible values: `one`, `two` and `three`. 

Correct arrays (should pass validation):

    []
    [&quot;one&quot;, &quot;one&quot;]
    [&quot;one&quot;, &quot;three&quot;]

Incorrect:

    [&quot;four&quot;]

Now, I know the `&quot;enum&quot;` property should be used, but I can&#39;t find relevant information where to put it.

Option A (under `&quot;items&quot;`):
    
    {
        &quot;type&quot;: &quot;array&quot;,
        &quot;items&quot;: {
            &quot;type&quot;: &quot;string&quot;,
            &quot;enum&quot;: [&quot;one&quot;, &quot;two&quot;, &quot;three&quot;]
        }
    }

Option B:

    {
        &quot;type&quot;: &quot;array&quot;,
        &quot;items&quot;: {
            &quot;type&quot;: &quot;string&quot;

    }

Correct way to define array of enums in JSON schema

I need to change a JSON attribute&#39;s value in Java, I can get the value properly but I couldn&#39;t modify the JSON.

here is the code below 

      JsonNode blablas = mapper.readTree(parser).get(&quot;blablas&quot;);
        for (JsonNode jsonNode : blablas) {
            String elementId = jsonNode.get(&quot;element&quot;).asText();
            String value = jsonNode.get(&quot;value&quot;).asText();
            if (StringUtils.equalsIgnoreCase(elementId, &quot;blabla&quot;)) {
            	if(value != null &amp;&amp; value.equals(&quot;YES&quot;)){
            		 // I need to change the node to NO then save it into the JSON
            	}
            }
        }
What is the best way to do this?

How to modify JsonNode in Java?

I would like to know the difference between `@JsonManagedReference` and `@JsonBackReference` in Jackson? 

JsonManagedReference vs JsonBackReference

I am able to serialize and deserialize a class hierarchy where the abstract base class is annotated with 

    @JsonTypeInfo(
        use = JsonTypeInfo.Id.MINIMAL_CLASS,
        include = JsonTypeInfo.As.PROPERTY,
        property = &quot;@class&quot;)

but no `@JsonSubTypes` listing the subclasses, and the subclasses themselves are relatively unannotated, having only a `@JsonCreator` on the constructor.  The ObjectMapper is vanilla, and I&#39;m not using a mixin.

Jackson documentation on [PolymorphicDeserialization and &quot;type ids&quot;][1] suggests (strongly) I need the `@JsonSubTypes` annotation on the abstract base class, or use it on a mixin, or that I need to [register the subtypes with the ObjectMapper][2].  And there are plenty of SO questions and/or blog posts that agree.  Yet it works. (*This is Jackson 2.6.0.*)

So ... am I the beneficiary of an as-yet-undocumented feature or am I relying on undocumented behavior (that may change) or is something else going on?  (I&#39;m asking because I really don&#39;t want it to be either of the latter two.  But [I gots to know][3].)

EDIT: Adding code - and one comment.  The comment is:  I should have mentioned that all the subclasses I&#39;m deserializing are in the same package and same jar as the base abstract class.

Abstract base class:

    package so;
    import com.fasterxml.jackson.annotation.JsonTypeInfo;

    @JsonTypeInfo(
        use = JsonTypeInfo.Id.MINIMAL_CLASS,
        include = JsonTypeInfo.As.PROPERTY,
        property = &quot;@class&quot;)
    public abstract class PolyBase
    {
        public PolyBase() { }

        @Override
        public abstract boolean equals(Object obj);
    }

A subclass of it:

    package so;
    import org.apache.commons.lang3.builder.EqualsBuilder;
    import com.fasterxml.jackson.annotation.JsonCreator;
    import com.fasterxml.jackson.annotation.JsonProperty;

    public final class SubA extends PolyBase
    {
        private final int a;

        @JsonCreator
        public SubA(@JsonProperty(&quot;a&quot;) int a) { this.a = a; }

        public int getA() { return a; }

        @Override
        public boolean equals(Object obj) {
            if (null == obj) return false;
            if (this == obj) return true;
            if (this.getClass() != obj.getClass()) return false;

            SubA rhs = (SubA) obj;
            return new EqualsBuilder().append(this.a, rhs.a).isEquals();
        }
    }

Subclasses `SubB` and `SubC` are the same except that field `a` is declared `String` (not `int`) in `SubB` and `boolean` (not `int`) in `SubC` (and the method `getA` is modified accordingly).

        }
    
        @Test
        public void jackson_should_or_should_not_deserialize_without_JsonSubTypes() {
    
            // Arrange
            PolyBase pb1 = new SubA(5), pb2 = new SubB(&quot;foobar&quot;), pb3 = new SubC(true);
            TestClass sut = new TestClass(pb1, pb2, pb3);
    
            ObjectMapper mapper = new ObjectMapper();
    
            // Act
            String actual1 = null;
            TestClass actual2 = null;
    
            try {
                actual1 = mapper.writeValueAsString(sut);
            } catch (IOException e) {
                fail(&quot;didn&#39;t serialize&quot;, e);
            }
    
            try {
                actual2 = mapper.readValue(actual1, TestClass.class);
            } catch (IOException e) {
                fail(&quot;didn&#39;t deserialize&quot;, e);
            }
    
            // Assert
            assertThat(actual2).isEqualTo(sut);
        }
    }

This test passes and if you break at the second `try {` line you can inspect `actual1` and see:

    {&quot;pb1&quot;:{&quot;@class&quot;:&quot;.SubA&quot;,&quot;a&quot;:5},
     &quot;pb2&quot;:{&quot;@class&quot;:&quot;.SubB&quot;,&quot;a&quot;:&quot;foobar&quot;},
     &quot;pb3&quot;:{&quot;@class&quot;:&quot;.SubC&quot;,&quot;a&quot;:true}}

So the three subclasses got properly serialized (each with their class name as id) and then deserialized, and the result compared equal (each subclass has a &quot;value type&quot; `equals()`).

Is Jackson&#39;s @JsonSubTypes still necessary for polymorphic deserialization?

I&#39;m trying and failing to deserialize an enum with Jackson 2.5.4, and I don&#39;t quite see my case out there. My input strings are camel case, and I want to simply map to standard Enum conventions.

    @JsonFormat(shape = JsonFormat.Shape.STRING)
    public enum Status {
        READY(&quot;ready&quot;),
        NOT_READY(&quot;notReady&quot;),
        NOT_READY_AT_ALL(&quot;notReadyAtAll&quot;);

        private static Map&lt;String, Status&gt; FORMAT_MAP = Stream
                .of(Status.values())
                .collect(toMap(s -&gt; s.formatted, Function.&lt;Status&gt;identity()));

        private final String formatted;

        Status(String formatted) {
            this.formatted = formatted;
        }

        @JsonCreator
        public Status fromString(String string) {
            Status status = FORMAT_MAP.get(string);
            if (status == null) {
                throw new IllegalArgumentException(string + &quot; has no corresponding value&quot;);
            }
            return status;
        }
    }

I&#39;ve also tried `@JsonValue` on a getter to no avail, which was an option I saw reported elsewhere. They all blow up with: 

    com.fasterxml.jackson.databind.exc.InvalidFormatException: Can not construct instance of ...Status from String value &#39;ready&#39;: value not one of declared Enum instance names: ...

What am I doing wrong?

Deserializing an enum with Jackson

This might be a duplicate. But I cannot find a solution to my Problem.

I have a class

    public class MyResponse implements Serializable {

        private boolean isSuccess;

        public boolean isSuccess() {
    		return isSuccess;
    	}
    
    	public void setSuccess(boolean isSuccess) {
    		this.isSuccess = isSuccess;
    	}
    }

Getters and setters are generated by Eclipse.

In another class, I set the value to true, and write it as a JSON string.

    System.out.println(new ObjectMapper().writeValueAsString(myResponse));

In JSON, the key is coming as `{&quot;success&quot;: true}`.

I want the key as `isSuccess` itself. Is Jackson using the setter method while serializing? How do I make the key the field name itself?
