I'm trying to build a spring mvc web on google app engine. But I can't make the routing/mapping work.
I have my HelloController, which indicates that I want to map to /hello
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
#Controller
#RequestMapping("/hello")
public class HelloController {
#RequestMapping(method = RequestMethod.GET)
public String Index() {
return "hello";
}
}
and a very simple hello.jsp file
<html>
<head><title>Hello :: Spring Application</title></head>
<body>
<h1>Hello - Spring Application</h1>
<p>Greetings.</p>
</body>
</html>
however, when I try to access /hello, I will get 404 not found.
here is my xml mapping file mvc-servlet.xml
<beans xmlns="http://www.springframework.org/schema/beans"

What am I missing ? How to fix it ?
Do you have a web.xml ?
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring/root-context.xml</param-value>
</context-param>
<!-- Creates the Spring Container shared by all Servlets and Filters -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</servlet-mapping>
ContextLoaderListener ties the ApplicationContext lifecycle to
ServletContext lifecycle and automate the creation of
ApplicationContext. ApplicationContext is the place for Spring beans
and we can provide it’s configuration through contextConfigLocation
context parameter. root-context.xml file provides the configuration
details for WebApplicationContext.

}
i search lots question like this,but no one can solved my problem,please help.
I believe, Spring can not find your controller.The problem might be with the component scan.
Please change your component scan directive from
<context:component-scan base-package="com.zhangbing.springmvc">
to
<context:component-scan base-package="com.zhangbing.springmvc.*">
Then lets see what is the output.
This one is tricky - for me at least.Component scan does not seem to work

Please note that if i put context:component-scan in applicationContext.xml ( not applicatinContext2.xml my service bean is detected. ). If there's other info i should provide do tell.
If I remember correctly, base package in component scan only requires a package name. Then all underlying sub-package will be included.
Therefore the correct setting should be
<context:component-scan base-package="ne.projl" />
There could be many reason, one common reason is you created your #Component class under wrong package.
As your context scanning config set the Class has to be under this package
<context:component-scan base-package="ne.projl.*" />
Posting the exception (if any) would provide more insight in to the issue for everyone here. Looks to me like a visibility problem.
If you are referencing to a component that is scanned in your applicationContext2, in one of your components that is loaded via contextConfigLocation, obviously it wont be visible.
.check this link for more info on visibility of application context
. I could not add a comment to the question..so i have posted my observations as answer.. Sorry for that
I am not sure but does not your web.xml says this
<!-- WEB-INF/applicationContext2.xml -->
is'nt that commented out ?
are you doing an import resource of applicationContext2 in applicationContext.xml file ?

So. Tomcat found controller, executed it, found view (page) and... Can't find mapping to it (page). Where is my mistake? Thanks for your answer
Change this:
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
to this:
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>

What is the correct way to use the two contexts: dispatcher-servlet.xml and applicationContext.xml? What goes where?
I want to write a fairly typical app deployed in a servlet container. It has some controllers with JSP views. It also has some nontrivial logic on the back-end. Do I really need both contexts? How are they related to each other? How can I decide what to put in which?
Also, I want to use Spring-security for my application. I may want to use its features (like declarative security with annotations) in web controllers as well as in deeper layers. How should I configure security to work in this case? Should it be in one of those files (which?), or both?
The dispatcher-servlet.xml file contains all of your configuration for Spring MVC. So in it you will find beans such as ViewHandlerResolvers, ConverterFactories, Interceptors and so forth. All of these beans are part of Spring MVC which is a framework that structures how you handle web requests, providing useful features such as databinding, view resolution and request mapping.
The application-context.xml can optionally be included when using Spring MVC or any other framework for that matter. This gives you a container that may be used to configure other types of spring beans that provide support for things like data persistence. Basically, in this configuration file is where you pull in all of the other goodies Spring offers.
These configuration files are configured in the web.xml file as shown:
Dispatcher Config
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>WEB-INF/spring/servlet-context.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
Application Config
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring/application-context.xml</param-value>
</context-param>
<!-- Creates the Spring Container shared by all Servlets and Filters -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
To configure controllers, annotate them with #Controller then include the following in the dispatcher-context.xml file:
<mvc:annotation-driven/>
<context:component-scan base-package="package.with.controllers.**" />
To add to Kevin's answer, I find that in practice nearly all of your non-trivial Spring MVC applications will require an application context (as opposed to only the spring MVC dispatcher servlet context). It is in the application context that you should configure all non-web related concerns such as:
Security
Persistence
Scheduled Tasks
Others?
To make this a bit more concrete, here's an example of the Spring configuration I've used when setting up a modern (Spring version 4.1.2) Spring MVC application. Personally, I prefer to still use a WEB-INF/web.xml file but that's really the only xml configuration in sight.

As you can see, the web configuration is only a small part of the overall spring web application configuration. Most web applications I've worked with have many concerns that lie outside of the dispatcher servlet configuration that require a full-blown application context bootstrapped via the org.springframework.web.context.ContextLoaderListener in the web.xml.

I am new to Spring. I am trying to integrate Spring in a section of a web app.
It has to work with urls like :
http://localhost:9080/myfolder/myspring
My web.xml includes:
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/config/myspring-context.xml
</param-value>
</context-param>
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/config/applicationContext.xml
</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/springviews</url-pattern>
</servlet-mapping>
applicationContext.xml :
<?xml version="1.0" encoding="UTF-8"?>

</beans>
my myspring-context.xml is :
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

<property name="suffix" value=".jsp" />
</bean>
</beans>
And here is MyController
package springcop;
import java.util.Map;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMethod;
#Controller
public class MyController {
public MyController () {
System.out.println("--->GestioneController");
}
#RequestMapping(value = "/test", method = RequestMethod.GET)
public String test() {
System.out.println("--->test");
return "test";
}
}
The up is runniong without errors. Spring seems to work as I have printed out in my log "--->GestioneController which is in the constructor of my COntroller.
Anyway, when I open in the browser
http://localhost:9080/myfolder/myspring/test
to execute the test method in MyController I get 404 error.
What's should I do to make it work?
Thanks.
Assuming that the name of your webapp is myfolder as listed in the question, the url would be...
http://localhost:9080/myfolder/springviews/test
The problem is you have the dispatcher servlet mapped to springviews. You need to map the dispatcher servlet as follows in web.xml...
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/<url-pattern>
</servlet-mapping>
Edit: Also, you have put your spring configuration in a context-param, but you did not add the listener to pick it up. Add the following to your web.xml....
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
