如何将struts2中的字符集更改为utf-8

Create a filter:

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;public class CharacterEncodingFilter implements Filter {    @Override    public void init(FilterConfig filterConfig) throws ServletException {    }    @Override    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {        servletRequest.setCharacterEncoding("UTF-8");        servletResponse.setContentType("text/html; charset=UTF-8");        filterChain.doFilter(servletRequest, servletResponse);    }    @Override    public void destroy() {    }}

Declare it into your web.xml:

<filter>    <filter-name>CharacterEncodingFilter</filter-name>    <filter-class>your.package.filter.CharacterEncodingFilter</filter-class></filter><filter-mapping>    <filter-name>CharacterEncodingFilter</filter-name>    <url-pattern>/*</url-pattern></filter-mapping>

而且你很好。还要确保您的每个JSP页面都包含：

<%@ page contentType="text/html;charset=UTF-8" language="java" %>

addURIEncoding="UTF-8"
