请指点这是什么原因造成的哦,我在myeclipse开启tomcat就不会出现此错误

web中的配置是

把jdk换到1.7或者将引入spring4.0以后的包就行了

同楼主遇到一样的问题了,敢问楼主是如何解决的?

springmvc3.20一样能用,在xml中这么配置

mvc:annotation-driven/mvc:annotation-driven
<!-- 对于注解的Handler可以单个配置
实际开发中建议使用组件扫描
-->
<!-- 可以扫描controller、service、...
这里让扫描controller,指定controller的包
-->
/context:component-scan

    <!-- 视图解析器 
        解析jsp,默认使用jstl标签,classpath下边得有jstl包
    -->
    <bean 
        class="org.springframework.web.servlet.view.InternalResourceViewResolver"></bean> 

把你的web.xml文件中配置的springmvc servlet贴出来

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

解决了吗???求分享

遇到同样问题了求分享

在吗?解决了吗分享一下吧

求解决方法,,遇到一样的问题

            <!-- 使用 mvc:annotation-driven代替注解映射器和注解适配器配置,mvc:annotation-driven默认加载很多的参数绑定方法,比如json转换解析器就默认加载了,如果使用mvc:annotation-driven不用配置上边的RequestMappingHandlerMapping和RequestMappingH实际开发时使用mvc:annotation-driven-->

servlet 过滤器 错误代码http status 404

我做了一个解决中文乱码的过滤器代码是这样的: package com.app.encoding; import java.io.IOException; import javax.servlet.FilterChain; import javax.servlet.FilterConfig; import javax.servlet.ServletException; import javax.servlet.ServletRequest; import javax.servlet.ServletResponse; class EncodingFilter implements javax.servlet.Filter { private String encoding; public void destroy() { // TODO Auto-generated method stub } public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { // TODO Auto-generated method stub request.setCharacterEncoding("GBK"); chain.doFilter(request, response); } public void init(FilterConfig filterConfig) throws ServletException { // TODO Auto-generated method stub encoding = filterConfig.getInitParameter("encoding"); } } web.xml的配置 <filter> <description>解决中文乱码</description> <filter-name>EncodingFilter</filter-name> <filter-class>com.app.encoding.EncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>GBK</param-value> </init-param> </filter> <filter-mapping> <filter-name>EncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> 没有写过滤器之前执行tomcat是能出现页面的,就是有中文乱码,但是加了过滤器之后就出现了 HTTP Status 404 The requested resource is not available. 弄了快一个上午了,还是搞不明白是哪里错误了,网上说路径错误,但是我检查了都没问题的,谢谢啦
