一：环境搭配
Struts的环境搭建基于Maven
在项目中的pom.xml加入struts:http://maven.apache.org/download.cgi
二：导入配置文件
三：配置xml
user
package com.zl;
public class User {
private String uid;
private String uname;
public String getUid() {
return uid;
}
public void setUid(String uid) {
this.uid = uid;
}
public String getUname() {
return uname;
}
public void setUname(String uname) {
this.uname = uname;
}
@Override
public String toString() {
return "User [uid=" + uid + ", uname=" + uname + "]";
}
public User(String uid, String uname) {
super();
this.uid = uid;
this.uname = uname;
}
public User() {
super();
// TODO Auto-generated constructor stub

注入与非注入
注入，注入需要实现ServletRequestAware接口，重写需要实现的方法setServletRequest；
将setServletRequest方法的参数私有化作为属性
