乱码有很多中原因
下面是其中一种解决办法，你可以试试

修改tomcat的conf/server.xml
把
<Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
改成
<Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" URIEncoding="UTF-8"/>

如果还乱码，请在web.xml中添加一个过滤器

<filter>    <filter-name>CharacterEncodingFilter</filter-name>    <filter-class>com.worthtech.app.filter.CharacterEncodingFilter</filter-class>    <init-param>      <param-name>encoding</param-name>      <param-value>UTF-8</param-value>    </init-param>    <init-param>      <param-name>ignore</param-name>      <param-value>true</param-value>    </init-param>  </filter>  <filter-mapping>    <filter-name>CharacterEncodingFilter</filter-name>    <url-pattern>/*</url-pattern>  </filter-mapping>

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 {private String encoding=null;private boolean ignore=true;public void destroy() {// TODO Auto-generated method stubencoding=null;}/**    * 过滤请求，用户提交请求时起作用    */  public void doFilter(ServletRequest request, ServletResponse response,FilterChain chain) throws IOException, ServletException {// TODO Auto-generated method stubif(ignore||request.getCharacterEncoding()==null){String encoding=getEncoding();if(encoding!=null){request.setCharacterEncoding(encoding);}}//System.out.println("encoding===="+encoding);response.setContentType("text/html;charset="+encoding);//do something here//当前工作全部完成后，将请求放开给过滤器链的下一filter chain.doFilter(request, response);}public void init(FilterConfig filterConfig) throws ServletException {// TODO Auto-generated method stubthis.encoding=filterConfig.getInitParameter("encoding");String value=filterConfig.getInitParameter("ignore");if(value==null){this.ignore=true;}else if(value.equalsIgnoreCase("true")){this.ignore=true;}else if(value.equalsIgnoreCase("yes")){this.ignore=true;}else{this.ignore=false;}}protected String getEncoding(){return this.encoding;}}
