jsp,servlet,struts等出现乱码的解决办法。

1.首先要保证jsp页面的编码格式、数据库编码格式、java文件保存格式、服务器server.xml中的URIEncoding编码格式保持一致
2 手动写一个过滤器，并且在web.xml文件中进行配置。
具体代码参考如下（调试通过）：
package cn.com.model2.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;
public class CharacterEncodingFilter implements Filter {
    public void destroy() {
        // TODO Auto-generated method stub
    }
    public void doFilter(ServletRequest request, ServletResponse response,
            FilterChain chain) throws IOException, ServletException {
        // TODO Auto-generated method stub
   
        request.setCharacterEncoding("utf-8");
        response.setCharacterEncoding("utf-8");
        chain.doFilter(request, response);
    }
    public void init(FilterConfig config) throws ServletException {
        // TODO Auto-generated method stub
    }
}
在web.xml文件中进行配置：
    <filter>
        <filter-name>CharacterEncoding Set</filter-name>
        <filter-class>cn.com.model2.util.CharacterEncodingFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>CharacterEncoding Set</filter-name>
        <url-pattern>/*</url-pattern>
    </fi
