springmvc页面跳转404问题

[Miracle^Z]

springmvc.xml的配置

    <context:component-scan base-package="com.takeout">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="suffix" value=".jsp"/>
        <property name="prefix" value="/WEB-INF/pages/"/>
     </bean>

      <!--配置静态资源-->
    <mvc:resources mapping="/css/**" location="/css/"/>
    <mvc:resources mapping="/img/**" location="/img/"/>
    <mvc:resources mapping="/js/**" location="/js/"/>
    <mvc:annotation-driven/>

web的配置

  <!--整合spring和springmvc 配置监听器-->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <!--配置路径-->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath*:spring.xml</param-value>
  </context-param>

  <servlet>
    <servlet-name>dispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath*:springmvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/*</url-pattern>
  </servlet-mapping>

  <!--解决乱码-->
  <filter>
    <filter-name>characterEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>UTF-8</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>characterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

controller代码

@Controller
public class userController {
    @RequestMapping("/user/login")
    public String login(){
        System.out.println("controller");
        return "ha";
    }
}

index.jsp

<a href="user/login">111</a>

使用tomcat发布后，页面无法从index到ha，一直报错404，提示The requested resource is not available.有没有大佬帮忙看一下

[java_lincarrie]

1.controller层return "pages/index"; 2.在浏览器输入网址……(项目ip地址)/user/login.do 仅供参考，不知道其它配置是怎样的；404错误基本是前后端的url,页面名称不匹配问题，多检查下前后台交互的信息是否一致

[qq_42621977]

是不是因为请求转发和重定向的原因？

[HibernateCat]

楼主可以试试<a href="/user/login">111</a>这样 如果还不行 就把生成的target删掉 再编译下。 看看其中是否有ha.jsp 如果还没有 需要给maven中添加配置了。

[HibernateCat]

还有可能是你ModelAndView引得包不对 ，应该引用org.springframework.web.servlet.ModelAndView

[早睡身体真不戳]

我这样做成功了。 <a href="${contextPath}/admin/showStudent"/>
