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。
