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

<Connector port="8080" maxHttpHeaderSize="8192"    
                   maxThreads="150" minSpareThreads="25" maxSpareThreads="75"    
                   enableLookups="false" redirectPort="8443" acceptCount="100"    
                   connectionTimeout="20000" disableUploadTimeout="true" URIEncoding="UTF-8" />

 

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。
