spring中文乱码问题

第一：code

@RequestMapping(value = "/query/{keyword}", method = RequestMethod.GET, produces = "text/html;charset=UTF-8")
public String query(@PathVariable String keyword) {

}

第二：tomcat server.xml 中
<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443" URIEncoding="UTF-8"/>

注意：如果使用eclipse启动tomcat时，需要将workspace下面的server.xml 中的Connector也添加URIEncoding="UTF-8"

=======================================

    <filter>  
     <filter-name>CharacterEncodingFilter</filter-name>  
      <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>  
      <init-param>  
          <param-name>encoding</param-name>  
          <param-value>GBK</param-value>  
      </init-param>  
      <init-param>  <!--强制进行转换-->  
<param-name> forceEncoding</param-name>  
<param-value> true </param-value>  
    </init-param> 
  </filter>  
  <filter-mapping>  
     <filter-name>CharacterEncodingFilter</filter-name>  
     <url-pattern>/*</url-pattern>  
 </filter-mapping>

如果不加强制转化参数，无效

===================================

今天搭建spring3 mvc框架的时候，发现居然又出现了乱码（万恶的iso编码啊），想起之前解决post提交乱

      package com.mocha.servlet;

    import javax.servlet.ServletConfig;
    import javax.servlet.ServletException;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    import org.springframework.web.servlet.DispatcherServlet;

    public class EncodingDispatcherServlet extends DispatcherServlet {
     private String encoding;

     public void init(ServletConfig config) throws ServletException {
      encoding = config.getInitParameter("encoding");
      super.init(config);
     }

     protected void doService(HttpServletRequest request, HttpServletResponse response) throws Exception {
      request.setCharacterEncoding(encoding);
      super.doService(request, response);
     }
    }

然后将web.xml中的配置改为：

<servlet>
<servlet-name>spring</servlet-name>
<servlet-class>com.mocha.servlet.EncodingDispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</servlet>

<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>

OK，乱码消失，现在总结一下乱码的问题，get方法乱码解决方法一般是将tomcat中conf目录下server.xml文件中加入

而post方法解决乱码是设置一个专门处理编码转换的filter或者servlet。
