I am working on a web app that needs to integrate with an existing user database. I would still like to use the `[Authorize]` attributes, but I don&#39;t want to use the Identity framework. If I did want to use the Identity framework I would add something like this in the startup.cs file:

    services.AddIdentity&lt;ApplicationUser, IdentityRole&gt;(options =&gt;
    {
        options.Password.RequireNonLetterOrDigit = false;
    }).AddEntityFrameworkStores&lt;ApplicationDbContext&gt;()
      .AddDefaultTokenProviders();

I&#39;m assuming I have to add something else there, and then create some kind of class that implements a specific interface? Can somebody point me in the right direction? I&#39;m using RC1 of of asp.net 5 right now.

Since I&#39;ve updated my version of intelliJ (14.x to 15.x) it has started automatically collapsing single line methods in the `Java` editor:

Previous version:

    public void setContext(SecurityContext context) {
        this.context = context;
    }

Latest version:

    public void setContext(SecurityContext context) { this.context = context; }

Is there a way to prevent this?  I find the original version much easier on the eyes!

Thanks.

I am trying to pass path param and query params in a URL but I am getting a weird error. below is the code

    

        String url = &quot;http://test.com/Services/rest/{id}/Identifier&quot;
        Map&lt;String, String&gt; params = new HashMap&lt;String, String&gt;();
        params.put(&quot;id&quot;, &quot;1234&quot;);
        UriComponentsBuilder builder = UriComponentsBuilder.fromUriString(url)
        									.queryParam(&quot;name&quot;, &quot;myName&quot;);
        String uriBuilder = builder.build().encode().toUriString();
        restTemplate.exchange(uriBuilder , HttpMethod.PUT, requestEntity,
    					class_p, params);

and my url is becoming `http://test.com/Services/rest/%7Bid%7D/Identifier?name=myName`

what should I do to make it work. I am expecting `http://test.com/Services/rest/{id}/Identifier?name=myName` so that params will add id to the url

please suggest. thanks in Advance

As I am trying this with spring boot and webservices with postman chrome add-ons.

In postman `content-type=&quot;multipart/form-data&quot;` and I am getting the below exception.

    HTTP Status 500 - Request processing failed; 
    nested exception is org.springframework.web.multipart.MultipartException: Could not parse multipart servlet request; 
    nested exception is java.io.IOException: 
    org.apache.tomcat.util.http.fileupload.FileUploadException: the request was rejected because no multipart boundary was found

In Controller I specified the below code

    @ResponseBody
	@RequestMapping(value = &quot;/file&quot;, headers = &quot;Content-Type= multipart/form-data&quot;, method = RequestMethod.POST)

	public String upload(@RequestParam(&quot;name&quot;) String name,
			@RequestParam(value = &quot;file&quot;, required = true) MultipartFile file)
	//@RequestParam ()CommonsMultipartFile[] fileUpload
	{
		// @RequestMapping(value=&quot;/newDocument&quot;, , method = RequestMethod.POST)
		if (!file.isEmpty()) {
			try {
				byte[] fileContent = file.getBytes();
				fileSystemHandler.create(123, fileContent, name);
				return &quot;You successfully uploaded &quot; + name + &quot;!&quot;;
			} catch (Exception e) {
				return &quot;You failed to upload &quot; + name + &quot; =&gt; &quot; + e.getMessage();
			}
		} else {
			return &quot;You failed to upload &quot; + name + &quot; because the file was empty.&quot;;
		}
	}


Here I specify the file handler code

    public String create(int jonId, byte[] fileContent, String name) {
		String status = &quot;Created file...&quot;;
		try {
			String path = env.getProperty(&quot;file.uploadPath&quot;) + name;
			File newFile = new File(path);
			newFile.createNewFile();
			BufferedOutputStream stream = new BufferedOutputStream(new FileOutputStream(newFile));
			stream.write(fileContent);
			stream.close();
		} catch (IOException ex) {
			status = &quot;Failed to create file...&quot;;
			Logger.getLogger(FileSystemHandler.class.getName()).log(Level.SEVERE, null, ex);
		}
		return status;
	}

When using the Google Execution Api for Java, the ID of the spreadsheet isn&#39;t very easy to understand. Here is the code snippet:

    // Initialize parameters for that function.
    String sheetId = &quot;&lt;ENTER_ID_OF_SPREADSHEET_TO_EXAMINE_HERE&gt;&quot;;
    List&lt;Object&gt; params = new ArrayList&lt;Object&gt;();
    params.add(sheetId);

Any Ideas on how to locate this. I run the Sheets api to return the id of a SpreadSheet but it returns a link, and when I use the https://spreadsheets.google.com/feeds/spreadsheets/*STRING* or just the *STRING* itself I still get:
&quot;code&quot; : 404,
  &quot;errors&quot; : [ {
    &quot;domain&quot; : &quot;global&quot;,
    &quot;message&quot; : &quot;Requested entity was not found.&quot;,
    &quot;reason&quot; : &quot;notFound&quot;

I have a Spring MVC `@Controller` with this constructor:

    @Autowired
    public AbcController(XyzService xyzService, @Value(&quot;${my.property}&quot;) String myProperty) {/*...*/}

I want to write a standalone unit test for this Controller:

    @RunWith(MockitoJUnitRunner.class)
    public class AbcControllerTest {
    
        @Mock
        private XyzService mockXyzService;
    
        private String myProperty = &quot;my property value&quot;;
    
        @InjectMocks
        private AbcController controllerUnderTest;
    
        /* tests */
    }

Is there any way to get `@InjectMocks` to inject my String property? I know I can&#39;t mock a String since it&#39;s immutable, but can I just inject a normal String here?

`@InjectMocks` injects a null by default in this case. `@Mock` understandably throws an exception if I put it on `myProperty`. Is there another annotation I&#39;ve missed that just means &quot;inject this exact object rather than a Mock of it&quot;?

IntelliJ keeps formatting this:

    public void addElement(Element elem) {
        this.elements.add(elem);
    }

into this:

    public void addElement(Element elem) { this.elements.add(elem); }

I prefer the multi-line formatting. How can I tell this to IntelliJ? I have unchecked the following boxes in Settings -&gt; Editor -&gt; Java -&gt; Wrapping and Braces

- Control statements in one line
- Simple blocks in one line
- Simple methods in one line

I have the lombok plugin setup in IntelliJ and my code builds fine. I can see the lombok generated methods in the structure view. What I want is some way to actually see the source lombok generates for each of the methods. I realize I can delombok the file but I&#39;m wondering if there is some way I can flip a switch to show or hide the lombok generated code.

Last week I was working on a Java EE project with IntelliJ IDE.

Today: As I started up my IntelliJ 2016.1 and it gave me the error:

**Error Loading Project**

*Cannot load module FirstWebApp*

As I looked at the details it said it could not find my FirstWebApp.iml file and so could not load my project. 

I checked out my project structure in the Explorer and everything except the iml file were there. I also looked at the Recycle Bin but I couldn&#39;t find it there as well.

 - How can such a file just disappear?
   
 - How can I get my iml file back if its possible? 
   
 - What do these iml files do?

I&#39;m new in the Java World. If more information is needed just comment! :)

According to the [Python 2.7.12 documentation][1]:

&gt; `!s` (apply `str()`) and `!r` (apply `repr()`) can be used to convert
&gt; the value before it is formatted.
&gt; 
&gt;     &gt;&gt;&gt; import math
&gt;     &gt;&gt;&gt; print &#39;The value of PI is approximately {}.&#39;.format(math.pi)
&gt;     The value of PI is approximately 3.14159265359.
&gt;     &gt;&gt;&gt; print &#39;The value of PI is approximately {!r}.&#39;.format(math.pi)
&gt;     The value of PI is approximately 3.141592653589793.

Interestingly, the converted value is the output of `repr()`, rather than `str()`.

    &gt;&gt;&gt; str(math.pi)
    &#39;3.14159265359&#39;
    &gt;&gt;&gt; repr(math.pi)
    &#39;3.141592653589793&#39;

So what does &quot;convert the value&quot; mean here? Making it less human-readable?

I&#39;m new to Swift programming and I&#39;ve been creating a simple tip calculator app in Xcode 8.2, I have my calculations set up within my `IBAction` below. But when I actually run my app and input an amount to calculate (such as 23.45), it comes up with more than 2 decimal places. How do I format it to `.currency` in this case?




    @IBAction func calculateButtonTapped(_ sender: Any) {
        
        var tipPercentage: Double {
            
            if tipAmountSegmentedControl.selectedSegmentIndex == 0 {
                return 0.05
            } else if tipAmountSegmentedControl.selectedSegmentIndex == 1 {
                return 0.10
            } else {
                return 0.2
            }
        }
        
        let billAmount: Double? = Double(userInputTextField.text!)
        
        if let billAmount = billAmount {
            let tipAmount = billAmount * tipPercentage
            let totalBillAmount = billAmount + tipAmount
            
            tipAmountLabel.text = &quot;Tip Amount: $\(tipAmount)&quot;
            totalBillAmountLabel.text = &quot;Total Bill Amount: $\(totalBillAmount)&quot;
        }
    }

I tried adding `&lt;br /&gt;` tag to fix the new string start, now it works, but I don&#39;t understand how to add spaces before the string starts without changing everything to `&amp;nbsp;`. Maybe there&#39;s a more elegant way to format it?
