jsp 提交表单乱码解决方案（post/get）  

 

 

解决乱码基本上添加拦截器就可以了，get / post 提交都全部搞定。不过第二条经过我的验证，不设置视乎也可以。

第一条是在action里面对接收到的单条参数进行转换

 

1. String name=new String((user.getUname()).getBytes("ISO-8859-1"),"utf8");

 

2. 在TOMCAT 6 的 server.xml里面设置：(tomcat 7 不支持)

 

添加：URLEncoding="UTF-8"

<Connector port="6060" protocol="HTTP/1.1" 

               connectionTimeout="20000" 

               redirectPort="8443" URIEncoding="UTF-8" 

useBodyEncodingForURI="true" 

/>

 

3. 自己写Filter  ：必须放在web.xml的最前面。下面2个拦截器都可以用，经过测试了

 

<!-- struts 的中文乱码拦截器

<filter>

<filter-name>encodeFilter</filter-name>

<filter-class>com.soodeep.util.MyEncodingIntercpter</filter-class>

<init-param>

<param-name>encoding</param-name>

<param-value>GBK</param-value>

</init-param>

</filter>

<filter-mapping>

<filter-name>encodeFilter</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>

-->

 

 

 

 

<!-- spring的中文乱码拦截器

<filter>

         <filter-name>EncodingFilter</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>EncodingFilter</filter-name>

         <url-pattern>/*</url-pattern>

     </filter-mapping>

-->

 

 

====================Struts 2 拦截器是我自定义的

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

package com.soodeep.util;

 

import java.io.IOException;

 

import javax.servlet.Filter;

import javax.servlet.FilterChain;

import javax.servlet.FilterConfig;

import javax.servlet.ServletException;

import javax.servlet.ServletRequest;

import javax.servlet.ServletResponse;

 

import org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter;

 

public class MyEncodingIntercpter extends StrutsPrepareAndExecuteFilter

implements Filter {

 

private FilterConfig config = null;

private String encoding = null;

 

@Override

public void init(FilterConfig config) throws ServletException {

this.config = config;

}

 

@Override

public void doFilter(ServletRequest request, ServletResponse response,

FilterChain chain) throws IOException, ServletException {

if(encoding==null){

encoding = config.getInitParameter("encoding");

System.out.println("encoding = "+encoding);

}

request.setCharacterEncoding(encoding);

response.setCharacterEncoding(encoding);

response.setContentType("text/html;charset=" + encoding);

chain.doFilter(request, response);

}

 

@Override

public void destroy() {

config = null;

encoding = null;

}

 

}
