This actually ended up being fairly simple.  To get a Java-config bean definition into the xml-config, simply define the Java-config class as a bean within the XML-config.  There are no extra jars necessary.

    @Configuration
    public class SomeJavaConfig {

        @bean
        ... [bean definition]
    }

inside the XML-config, you define this class as a bean.

    &lt;!-- needed to pick up the annotated java-config --&gt;
    &lt;context:annotation-config /&gt;

    &lt;!-- Importing java-config class, which are annotated with @Configuration --&gt;
    &lt;bean name=&quot;SomeJavaConfig&quot; class=&quot;[fully qualified path].SomeJavaConfig&quot; /&gt;

The XML-config, which may be part of a different context, now has all the bean definitions defined within the JavaConfig class.


**UPDATED** - to included Alan Franzoni&#39;s comment below in the answer.


Alternatively to `annotation-config` you can use `component-scan`. Then you do not have to include the Configuration Bean in XML:

    &lt;context:component-scan base-package=&quot;[fully qualified package path]&quot; /&gt;

See https://stackoverflow.com/questions/7414794/difference-between-contextannotation-config-vs-contextcomponent-scan for more details.

Should be in:

    spring-javaconfig-&lt;version&gt;.jar



Why is the implementation of [`startwith`](http://docs.python.org/2/library/stdtypes.html#str.startswith) slower than slicing?

    In [1]: x = &#39;foobar&#39;
    
    In [2]: y = &#39;foo&#39;
    
    In [3]: %timeit x.startswith(y)
    1000000 loops, best of 3: 321 ns per loop
    
    In [4]: %timeit x[:3] == y
    10000000 loops, best of 3: 164 ns per loop
    
Surprisingly, even including calculation for the length, slicing still appears significantly faster:

    In [5]: %timeit x[:len(y)] == y
    1000000 loops, best of 3: 251 ns per loop

*Note: the first part of this behaviour is noted in [**Python for Data Analysis**](http://shop.oreilly.com/product/0636920023784.do) (Chapter 3), but no explanation for it is offered.*

.

If helpful: [here is the C code for `startswith`](http://hg.python.org/cpython/file/4ebe1ede981e/Objects/stringobject.c#l2903); and here is the output of [`dis.dis`](https://stackoverflow.com/questions/12673074/how-should-i-understand-the-output-of-dis-dis): 
    

    In [6]: import dis

I&#39;m using Express, which loads AngularJS from a static directory.  Normally, I will request `http://localhost/`, in which Express serves me my `index.html` and all of the correct Angular files, etc.  In my Angular app, I have these routes setup, which replace the content in an `ng-view`:

    $routeProvider.when(&#39;/&#39;, {
		templateUrl: &#39;/partials/main.html&#39;,
		controller: MainCtrl,
	});

	$routeProvider.when(&#39;/project/:projectId&#39;, {
		templateUrl: &#39;/partials/project.html&#39;,
		controller: ProjectCtrl,
	});
	
	$locationProvider.html5Mode(true);

On my main page, I have a link to `&lt;a href=&quot;/project/{{project.id}}&quot;&gt;`, which will successfully load the template and direct me to `http://localhost/project/3` or whatever ID I have specified.  The problem is when I try to direct my browser to `http://localhost/project/3` or refresh the page, the request is going to the Express/Node server, which returns `Cannot GET /project/3`.  

How do I setup my Express routes to accommodate for this?  I&#39;m guessing it will require the use of [`$location`][1] in Angular (although I&#39;d prefer to avoid the ugly ?searches and #hashes they use), but I&#39;m clueless about how to go about setting up the Express routes to handle this.

Thanks.

I have a project where I need to bootstrap @Configuration java-config classes into the XML configuration.

To do that, I&#39;m reading that I also need to include the following bean definition (along with the bean definitions of the classes annotated with @Configuration).

    &lt;bean class=&quot;org.springframework.config.java.process.ConfigurationPostProcessor&quot; /&gt;

But, I end up receiving the following error:

    Caused by: java.lang.ClassNotFoundException: org.springframework.config.java.process.ConfigurationPostProcessor

I have to assume I&#39;m missing a jar somewhere, but my various web searches hasn&#39;t resulted in an answer yet.  Any help would be greatly appreciated.  Thanks.


**EDIT**:  Evidently, I was reading old documentation, which is no longer current.  Let me back up.  My project contains older XML-based configuration.  The newer code is all using &#39;Java-config&#39;.  With that said, the contexts are apparently completely separate.  I&#39;d like to &#39;import&#39; a java-config class into the XML configuration, so that both contexts have those particular beans.  Does anyone know how I can do that?

EDIT: Evidently, I was reading old documentation, which is no longer current. Let me back up. My project contains older XML-based configuration. The newer code is all using 'Java-config'. With that said, the contexts are apparently completely separate. I'd like to 'import' a java-config class into the XML configuration, so that both contexts have those particular beans. Does anyone know how I can do that?

I&#39;ve got a web application where I have the typical problem that it requires different configuration files for different environments. Some configuration is placed in the application server as JNDI datasources, however some configuration stays in property files.

Therefore I want to use the Spring profiles feature.

My problem is that I don&#39;t get the test case running.

context.xml:

    &lt;context:property-placeholder 
      location=&quot;classpath:META-INF/spring/config_${spring.profiles.active}.properties&quot;/&gt;

Test:
   
    @RunWith(SpringJUnit4ClassRunner.class)
    @TestExecutionListeners({
		TestPreperationExecutionListener.class
		})
    @Transactional
    @ActiveProfiles(profiles = &quot;localtest&quot;)
    @ContextConfiguration(locations = {
		&quot;classpath:context.xml&quot; })
    public class TestContext {

	  @Test
	  public void testContext(){

	  }
    }

The problem seems to be that the variable for loading the profile isn&#39;t resolved:

    Caused by: java.io.FileNotFoundException: class path resource [META-INF/spring/config_${spring.profiles.active}.properties] cannot be opened because it does not exist
	at org.springframework.core.io.ClassPathResource.getInputStream(ClassPathResource.java:157)
	at org.springframework.core.io.support.PropertiesLoaderSupport.loadProperties(PropertiesLoaderSupport.java:181)
	at org.springframework.core.io.support.PropertiesLoaderSupport.mergeProperties(PropertiesLoaderSupport.java:161)
	at org.springframework.context.support.PropertySourcesPlaceholderConfigurer.postProcessBeanFactory(PropertySourcesPlaceholderConfigurer.java:138)
	... 31 more

The current profile should be set with the `@ActiveProfile` annotation. As it&#39;s a test case I won&#39;t be able to use the `web.xml`. If possible I&#39;d like to avoid runtime options as well. The test should run as is (if possible).

How can I properly activate the profile? Is it possible to set the profile with a context.xml? Could I declare the variable in a test-context.xml that is actually calling the normal context?

Spring profiles and testing

In this period I am studing the Spring MVC showcase example (downloadable from STS dasboard) and I have some simple question about the `Request Mapping` examples:

1) In my `home.jsp` page I have this link:

			&lt;li&gt;
				&lt;a id=&quot;byParameter&quot; class=&quot;textLink&quot; href=&quot;&lt;c:url value=&quot;/mapping/parameter?foo=bar&quot; /&gt;&quot;&gt;By path, method, and presence of parameter&lt;/a&gt;
			&lt;/li&gt;

As you can see by this link I am doing an HTTP GET Request having a &quot;foo&quot; parameter containing the value: &quot;bar&quot;.

This HTTP Request is handled by the following method of the controller class MappingController:

	@RequestMapping(value=&quot;/mapping/parameter&quot;, method=RequestMethod.GET, params=&quot;foo&quot;)
	public @ResponseBody String byParameter() {
		return &quot;Mapped by path + method + presence of query parameter! (MappingController)&quot;;
	}

This method manage HTTP Request (only `GET` type) that have a parameter named &quot;foo&quot;

How can I take the value (&quot;bar&quot;) of this parameter and put it in a variable inside the code of my by Parameter method?

Spring MVC How take the parameter value of a GET HTTP Request in my controller method?

What is the difference between the following dependencies?

&lt;!-- language: xml --&gt;

    &lt;dependency&gt;
        &lt;groupId&gt;org.springframework&lt;/groupId&gt;
        &lt;artifactId&gt;spring-webmvc&lt;/artifactId&gt;
        &lt;version&gt;3.1.2.RELEASE&lt;/version&gt;
    &lt;/dependency&gt;
            
vs

    &lt;dependency&gt;
        &lt;groupId&gt;org.springframework&lt;/groupId&gt;
        &lt;artifactId&gt;spring-web&lt;/artifactId&gt;
        &lt;version&gt;3.1.2.RELEASE&lt;/version&gt;
    &lt;/dependency&gt;

If I include `spring-webmvc` alone then `spring-web` is implicitly added. 

When should we use `spring-web` alone?

There are two methods defined in **ABC.java**

    public void method1(){
       .........
       method2();
      ...........
    }
    
    
    public void method2(){
      ...............
      ...............  
    }
I want to have AOP on call of **method2**.So,
I created one class,**AOPLogger.java**,having aspect functionality provided in a method **checkAccess**  
In configuration file, I did something like below

    &lt;bean id=&quot;advice&quot; class=&quot;p.AOPLogger&quot; /&gt;
    &lt;aop:config&gt;
      &lt;aop:pointcut id=&quot;abc&quot; expression=&quot;execution(*p.ABC.method2(..))&quot; /&gt;
      &lt;aop:aspect id=&quot;service&quot; ref=&quot;advice&quot;&gt;
        &lt;aop:before pointcut-ref=&quot;abc&quot; method=&quot;checkAccess&quot; /&gt;			
      &lt;/aop:aspect&gt;
    &lt;/aop:config&gt;

But when my method2 is called, AOP functionality is not getting invoked i.e. **checkAccess** method is not getting invoked of AOPLogger class.

Any thing i am missing?

I have following configuration class:

    @PropertySource(name = &quot;props&quot;, value = &quot;classpath:/app-config.properties&quot;)
    @ComponentScan(&quot;service&quot;)
    public class AppConfig {

and I have service with property:

    @Component 
    public class SomeService {
        @Value(&quot;#{props[&#39;some.property&#39;]}&quot;) private String someProperty;

I receive error when I want to test the AppConfig configuration class with

The issue is documented [in SPR-8539][1]


  [1]: https://jira.springsource.org/browse/SPR-8539 &quot;SPR-8539&quot;

but anyway I cannot figure out how to configure **PropertySourcesPlaceholderConfigurer**  to get it work.

I have an ASP.NET MVC3 C# .NET Application running on IIS 7.5.  

We have a Windows NT service account we Impersonate in our code in order to read/write documents to a file share. The user id is compiled in the code and the service account password is stored in the web.config file.  

The password contains an ampersand character (i.e.: `p&amp;ssword`).  

This broke the site.  When accessing the site we received this error :&quot;Sorry, an error occurred while processing your request&quot;.  

Here is the code that uses the password:

        var password = ConfigurationManager.AppSettings.Get(Common.SVC_PWD);

        bool isSuccess = LogonUser(
            @&quot;my_svc_acct&quot;,
            &quot;my.domain.net&quot;,

            LOGON32_LOGON_NEW_CREDENTIALS,
            LOGON32_PROVIDER_DEFAULT, ref token
        );

Why would this cause the site to break?

The &quot;&amp;&quot; character breaks passwords that are stored in the web.config

I&#39;m trying to upgrade my spring mvc project to utilize the new annotations and get rid of my xml. Previously I was loading my static resources in my `web.xml` with the line:

    &lt;mvc:resources mapping=&quot;/resources/**&quot; location=&quot;/resources/&quot; /&gt; 

Now, I&#39;m utilizing the `WebApplicationInitializer` class and `@EnableWebMvc` annotation to startup my service without any xml files, but can&#39;t seem to figure out how to load my resources. 

Is there an annotation or new configuration to pull these resources back in without having to use xml?
