You can use:

    @Autowired
    @Qualifier(&quot;beanname&quot;)

According to the [@Qualifier javadoc](http://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/beans/factory/annotation/Qualifier.html)

&gt; This annotation may be used on a field or parameter as a qualifier for candidate beans when autowiring

You can use JSR-250 `@Resource` for by-name bean autowiring, unless you need constructor injection or multi-parameter method injection.

From the docs:

&gt; If you intend to express annotation-driven injection by name, do not primarily use @Autowired, even if is technically capable of referring to a bean name through @Qualifier values. Instead, use the JSR-250 @Resource annotation, which is semantically defined to identify a specific target component by its unique name, with the declared type being irrelevant for the matching process.

If you want to define name of the bean with which they will be registered in DI container, you can pass the name in annotation itself e.g. **@Service (“employeeManager”).**


Then using below code you can enable autowire by Name

    @Autowired
    @Qualifier(&quot;employeeManager&quot;)
    private EmployeeManagerService employeeManagerService;



I was using bean name proxy which was messing up autowiring by name. @Resource didn&#39;t have that issue since it doesn&#39;t care about type. So now I know one reason for this recommendation by Spring developers :-) Just FYI

Use @Component(&quot;beanname&quot;) in the java class definition of your bean

Then while autowiring use JSR 330

@Inject
@Named(Value=&quot;beanname&quot;)

I&#39;m trying to get a nice fade-out effect at the bottom of a section of text as a &#39;read more&#39; indicator.  

I&#39;ve been following a bit off [this](http://css-tricks.com/text-fade-read-more/) and other tutorials, and my code currently is as follows:

###html

    &lt;section&gt;
        &lt;p&gt;malesuada fames ac turpis egestas...leo.&lt;/p&gt;                                                                  
        &lt;p&gt;malesuada fames ac turpis egestas...leo.&lt;/p&gt;
        &lt;div class=&quot;fadeout&quot;&gt;&lt;/div&gt;
    &lt;/section&gt;
    &lt;p&gt;Stuff after&lt;/p&gt;

###css

    .fadeout {
        position: relative; 
        bottom: 4em;
        height: 4em;
        background: -webkit-linear-gradient(
            rgba(255, 255, 255, 0) 0%,
            rgba(255, 255, 255, 1) 100%
        ); 
    } 

[jsFiddle](http://jsfiddle.net/6k3vV/) 

The problem is, even when I position the transparent div over the body of text, the 4em&#39;s of space still exists between &lt;section&gt;&lt;/section&gt; and &#39;Other Stuff.&#39;

Any ideas?

In Springs latest version, we can autowire a bean using annotation as `@Autowired`. This will autowire the bean using its type(or constructor, if applied on it).
Is there any way I can use the `@Autowired` annotation based on the bean name which we were doing without annotation in Spring&#39;s XML file as **autowire=&quot;byName&quot;**?

My requirement is as follows:

I want to give actor name, start date, end date and get all the films he acted in that period. 

For that reason, my service request is like this. 

      http://localhost:8080/MovieDB/GetJson?name=Actor&amp;startDate=20120101&amp;endDate=20120505

Now, i want to improve it.
I want to give a start date, end date and more than one actor name and want to see all those actors movies in that period.

I am not sure how should my url look to support such thing.

   I am writing a java based web service using spring.

  Below code is to support one actor

       @RequestMapping(value = &quot;/GetJson&quot;, method = RequestMethod.GET) 
		public void getJson(@RequestParam(&quot;name&quot;) String ticker, @RequestParam(&quot;startDate&quot;) String startDate, @RequestParam(&quot;endDate&quot;) String endDate) {
       //code to get results from db for those params.
     }

One solution i am thinking is using a % symbol to seperate actor names. For example:

     http://localhost:8080/MovieDB/GetJson?name=Actor1%Actor2%Actor3&amp;startDate=20120101&amp;endDate=20120505

Now, in the controller i will parse the name string with % and get back all actors names.

Is this a good way to do this or is there a standard approach?

Thanks


how to send an array in url request

I am new to Spring and trying to inject a string with a value using the `@Value(&quot;${loginpage.message}&quot;)` annotation inside of a controller annotated with the `@Controller` annotation and the value of my string is being evaluated as the string `&quot;${loginpage.message}&quot;` and not what is inside my properties file.

Below is my controller with the string &#39;message&#39; that I want to inject.

    @Controller
    public class LoginController extends BaseController {
    	@Value(&quot;${loginpage.message}&quot;)
    	private String message;
    	
    	@RequestMapping(&quot;/&quot;)
    	public String goToLoginPage(Model model) {
    		model.addAttribute(&quot;message&quot;, message);
    		
    		return &quot;/login&quot;;
    	}
    }

My application context looks like this: 

	&lt;context:property-placeholder location=&quot;classpath:properties/application.properties&quot; /&gt;

	&lt;context:annotation-config /&gt;

	&lt;context:component-scan base-package=&quot;com.me.application&quot; /&gt;

My properties file has the line:

    loginpage.message=this is a test message

Spring must be picking up the value at some point because whenever I change `@Value(&quot;${loginpage.message}&quot;)` to a value not in the properties file like `@Value(&quot;${notInPropertiesFile}&quot;)`, I get an exception.


Spring @Value annotation in @Controller class not evaluating to value inside properties file

I want to receive some information per request, so I think instead of having a function for each request and obtaining those information from requests separately, &lt;b&gt;it&#39;s better to have a filter.&lt;br&gt;
So every request shall pass that filter and I gain what I want.&lt;/b&gt;&lt;br&gt;
&lt;br&gt;
The question is: How can I write a custom filter?&lt;br&gt;
_Suppose it is not like any predefined spring security filters and it is totally new._

How to write a custom filter in spring security?

I&#39;m currently using the @Value Spring 3.1.x annotation like this:

    @Value(&quot;${stuff.value:}&quot;)
    private String value;

This puts an empty String into the variable if the attribute is not present. I would like to have null as the default instead of an empty String. Of course I also want to avoid an error when the property stuff.value is not set.

Can I set null as the default value for a @Value in Spring?

Is there a way to specify that if the method returns null value, then don&#39;t cache the result in @Cacheable annotation for a method like this?

    @Cacheable(value=&quot;defaultCache&quot;, key=&quot;#pk&quot;)
    public Person findPerson(int pk) {
       return getSession.getPerson(pk);
    }

Update:
here is the JIRA issue submitted regarding caching null value last November, which hasn&#39;t resolved yet: 
[\[#SPR-8871\] @Cachable condition should allow referencing return value - Spring Projects Issue Tracker][1]

How do I tell Spring cache not to cache null value in @Cacheable annotation

I have the DataPrepareService that prepare data for reports and I have an Enum with report types, and I need to inject ReportService into Enum or have access to ReportService from enum.

my service:
&lt;!-- language: lang-java --&gt;

    @Service
    public class DataPrepareService {
        // my service
    }

my enum:
&lt;!-- language: lang-java --&gt;
	
    public enum ReportType {
    
        REPORT_1(&quot;name&quot;, &quot;filename&quot;),
        REPORT_2(&quot;name&quot;, &quot;filename&quot;),
        REPORT_3(&quot;name&quot;, &quot;filename&quot;)
    
        public abstract Map&lt;String, Object&gt; getSpecificParams();
    
        public Map&lt;String, Object&gt; getCommonParams(){
            // some code that requires service
        }
    }


I tried to use 

    @Autowired
    DataPrepareService dataPrepareService;

, but it didn&#39;t work

How can I inject my service into enum?

Inject bean into enum

I have a component setup that is essentially a launcher for an application. It is configured like so:

    @Component
    public class MyLauncher {
        @Autowired
        MyService myService;

        //other methods
    }

MyService is annotated with the `@Service` Spring annotation and is autowired into my launcher class without any issues. 

I would like to write some jUnit test cases for MyLauncher, to do so I started a class like this:

    public class MyLauncherTest
        private MyLauncher myLauncher = new MyLauncher();
        
        @Test
        public void someTest() {
    
        }
    }

Can I create a Mock object for MyService and inject it into myLauncher in my test class? I currently don&#39;t have a getter or setter in myLauncher as Spring is handling the autowiring. If possible, I&#39;d like to not have to add getters and setters. Can I tell the test case to inject a mock object into the autowired variable using an `@Before` init method?

If I&#39;m going about this completely wrong, feel free to say that. I&#39;m still new to this. My main goal is to just have some Java code or annotation that puts a mock object in that `@Autowired` variable without me having to write a setter method or having to use an `applicationContext-test.xml` file. I would much rather maintain everything for the test cases in the `.java` file instead of having to maintain a separate application content just for my tests.

I am hoping to use **Mockito** for the mock objects. In the past I have done this by using `org.mockito.Mockito` and creating my objects with `Mockito.mock(MyClass.class)`.

Injecting @Autowired private field during testing

I have `@Autowired` service which has to be used from within a static method. I know this is wrong but I cannot change the current design as it would require a lot of work, so I need some simple hack for that. I can&#39;t change `randomMethod()` to be non-static and I need to use this autowired bean. Any clues how to do that?

    @Service
    public class Foo {
        public int doStuff() {
            return 1;
        }
    }

    public class Boo {
        @Autowired
        Foo foo;
        
        public static void randomMethod() {
             foo.doStuff();
        }
    }



@Autowired and static method

I am reading the spring 3.0.x reference documentation to understand Spring Autowired annotation:

[3.9.2 @Autowired and @Inject][1]


I am not able to understand the below examples. Do we need to do something in the XML for it to work? 

EXAMPLE 1

    public class SimpleMovieLister {

        private MovieFinder movieFinder;

        @Autowired
        public void setMovieFinder(MovieFinder movieFinder) {
            this.movieFinder = movieFinder;
        }

        // ...
    }


EXAMPLE 2 

    public class MovieRecommender {

        private MovieCatalog movieCatalog;

        private CustomerPreferenceDao customerPreferenceDao;

        @Autowired
        public void prepare(MovieCatalog movieCatalog,
                        CustomerPreferenceDao customerPreferenceDao) {
            this.movieCatalog = movieCatalog;
            this.customerPreferenceDao = customerPreferenceDao;
        }

        // ...
    }

How can the two classes be autowired implementing the same interface and using the same class? 

Example: 

    class Red implements Color
    class Blue implements Color

    class myMainClass{
        @Autowired 
        private Color color;

        draw(){
            color.design(); 
        } 
    }

Which design method will be called? How do I make sure the design method of Red class will be called and not Blue?

Understanding Spring @Autowired usage

I have an issue with connecting environment to my Spring project.
In this class 

    @Configuration
    @ComponentScan(basePackages = &quot;my.pack.offer.*&quot;)
    @PropertySource(&quot;classpath:OfferService.properties&quot;)
    public class PropertiesUtil {
        @Autowired
        private Environment environment;

       

        @Bean
        public String load(String propertyName)
        {
            return environment.getRequiredProperty(propertyName);
        }
    }

environment always is null.
