Spring MVC配置

Question

我將eclipse和Jboss用於簡單Spring MVC應用程序的編碼。 我創建了一個企業應用程序，並在application.xml中將上下文根設置為myAppWeb。

我的web.xml詳細信息：

<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>

我的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>

現在，當我輸入網址為

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

我得到和404錯誤，日志消息為：

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

我將springspringapp-servlet.xml中的配置更改為

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

仍然無法正常工作。

有人可以幫我這個忙嗎？

謝謝！

對於我的項目，“ *-servlet.xml”文件為空：

<?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>

spring應用程序啟動時，“ web.xml”文件具有上下文偵聽器以讀取配置：

<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>

然后，上下文偵聽器指向的文件（'/WEB-INF/SpringAppServlet.xm'）包含您的配置：

<?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>

您需要通過將bean配置文件作為上下文參數傳遞，在web.xml中指定Context loader偵聽器，如下所示

<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>
