本文详细介绍了如何在Struts2.1.6环境下配置Tomcat，包括修改server.xml文件设置URI编码方式，并在src目录下创建并实现CharacterEncodingFilter过滤器。同时，对web.xml文件进行修改，部署该过滤器以确保应用中所有请求的字符编码统一为UTF-8。

环境：

struts2.1.6

tomcat7

myeclipse blue 10

<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" URIEncoding="UTF-8"/>

2.在src目录下建立CharacterEncodingFilter.java,编写过滤器CharacterEncodingFilter，代码如下


 1: package com.hellopclee;


 2: import java.io.IOException;

3:


 4: import javax.servlet.Filter;


 5: import javax.servlet.FilterChain;


 6: import javax.servlet.FilterConfig;


 7: import javax.servlet.ServletException;


 8: import javax.servlet.ServletRequest;


 9: import javax.servlet.ServletResponse;

10:


 11: public class CharacterEncodingFilter implements Filter{

12:


 13: @Override


 14: public void destroy() {


 15: }

16:


 17: @Override


 18: public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException,ServletException {


 19: request.setCharacterEncoding("utf-8");


 20: chain.doFilter(request, response);


 21: }

22:


 23: @Override


 24: public void init(FilterConfig arg0) throws ServletException {


 25: }

26:


 27: }

3.修改项目里的web.xml文件，部署上面的过滤器。在<display-name></display-name>下面加上一下代码


 1: <filter>


 2: <filter-name>characterEncoding</filter-name>


 3: <filter-class>com.hellopclee.CharacterEncodingFilter</filter-class>


 4: </filter>


 5: <filter-mapping>


 6: <filter-name>characterEncoding</filter-name>


 7: <url-pattern>/*</url-pattern>


 8: </filter-mapping>

4.重启服务器
