1、<form action="user!add" method="post"> 必表单提交方法必须为post，如果是get就出错

Action1.java

package com.ncepu.struts2;public class Action1 {private String name;private String password; //传递参数的时候  用的是方法 而不是赋给属性，                       //所以说将password改成userpassword下面方法setPassword不变也可以。                       public String getName() {return name;}public void setName(String name) {this.name = name;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}public String add() {        System.out.println("添加的name="+name+"添加的password="+password);return ("success");}}

struts.xml

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE struts PUBLIC    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"    "http://struts.apache.org/dtds/struts-2.0.dtd"><struts><constant name="struts.devMode" value="true" /><package name="default" namespace="/" extends="struts-default"><action name="user" class="com.ncepu.struts2.Action1"><result name="success">/add.jsp            </result></action></package></struts>

index.jsp

<body><!--必须为post--><form action="user!add" method="get">姓名2<input type="text" name="name">密码1<input type="text" name="password"><input type="submit" value="submit" /></form></body>

后台输出为：添加的name=°?????·?添加的password= °?·??÷

解决方法：
1、必须将<form action="user!add" method="post"> 必表单提交方法必须为post才正确。

2、对请求参数重新编码（参照http://blog.csdn.net/ncepustrong/article/details/7927027)

String name = new String(request.getParameter("name").getBytes("ISO8859-1"));String password= new String(request.getParameter("password").getBytes("ISO8859-1"));

在此使用到了request，必须得到。

package com.ncepu.struts2;import java.io.UnsupportedEncodingException;import javax.servlet.http.HttpServletRequest;import org.apache.struts2.ServletActionContext;import com.opensymphony.xwork2.ActionSupport;public class Action1 extends ActionSupport {private static final long serialVersionUID = 1L;HttpServletRequest request;private String name;private String password; // 传递参数的时候 用的是方法 而不是赋给属性，// 所以说将password改成userpassword下面方法setPassword不变也可以。public String getName() {return name;}public Action1() {request = ServletActionContext.getRequest();}public void setName(String name) {this.name = name;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}public String add() throws UnsupportedEncodingException {name = new String(request.getParameter("name").getBytes("ISO8859-1"));password = new String(request.getParameter("password").getBytes("ISO8859-1"));System.out.println("添加的name=" + name + "添加的password=" + password);return ("success");}}
