Spring MVC配置

Question

I am using eclipse and Jboss for my coding of a simple Spring MVC application. I have created an enterprise application and I set the context-root as myAppWeb in application.xml.

My web.xml details:

<servlet>
<servlet-name>springapp</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springapp</servlet-name>
<url-pattern>*.htm</url-pattern>
</servlet-mapping>

My springspringapp-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans      http://www.springframework.org/schema/beans/spring-beans-4.0.xsd">

<!-- the application context definition for the springapp DispatcherServlet -->

<bean name="/a.htm" class="com.init.servlet.test.HelloController" />

</beans>

Now when I am entering the URL as

"http://localhost:8080/myAppWeb/a.htm" 

I am getting and 404 error and the log message as:

" servlet.PageNotFound OO                 noHandlerFound() OO No mapping found for HTTP request with URI [/myAppWeb/a.htm] in DispatcherServlet with name 'springapp'".

I changed the config in my springspringapp-servlet.xml as

<bean name="/myAppWeb/a.htm" class="com.init.servlet.test.HelloController" />

Still it is not working.

Could anyone help me out regarding this?

thanks!

For my projects, the '*-servlet.xml' file is empty:

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans      http://www.springframework.org/schema/beans/spring-beans-4.0.xsd">

</beans>

The 'web.xml' file has a context listener to read the configuration when spring application is booting:

<context-param>
    <param-name>contextConfigLocation</param-name> 
    <param-value>/WEB-INF/SpringAppServlet.xml</param-value>
</context-param>

<listener>
    <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> 
</listener>

Then, the file pointed by the context listener ('/WEB-INF/SpringAppServlet.xm')contains your configuration:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans      http://www.springframework.org/schema/beans/spring-beans-4.0.xsd">

<!-- the application context definition for the springapp DispatcherServlet -->

<bean name="/hello.htm" class="com.init.servlet.test.HelloController" />

</beans>

You need to specify Context loader listener in your web.xml by passing bean configuration file as context param as below

<context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/SpringAppServlet.xml</param-value> </context-param>

<listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener>
