struts2中多个逻辑action（方法）的动态调用

Struts2可以实现在同一个action中通过多个方法实现在配置文件中配置出多个逻辑的action，通过在js中给各个button添加onclick方法调用实现提交到不同的action。可以实现多个按钮的动态提交。并且可以通过在action中设置参数属性在struts.xml文件中的result中配置表达式来动态跳转到不同的逻辑视图

package com.inspur.action;

import java.util.Map;

import com.opensymphony.xwork2.ActionContext;

import com.opensymphony.xwork2.ActionSupport;

public class MyAction extends ActionSupport {

private String username;

private String password;

public String getUsername() {

return username;

}

public void setUsername(String username) {

this.username = username;

}

public String getPassword() {

return password;

}

public void setPassword(String password) {

this.password = password;

}

private String target;

private String tip;

public String getTarget() {

return target;

}

public void setTarget(String target) {

this.target = target;

}

public String getTip() {

return tip;

}

public void setTip(String tip) {

this.tip = tip;

}

public String login(){

if(this.getUsername().equals("lzhq")&&this.getPassword().equals("123")){

ActionContext actionContext=ActionContext.getContext();

Map session=actionContext.getSession();

session.put("user", this.getUsername());

return SUCCESS;

}else

return ERROR;

}

public String direct(){

if(this.getTarget().equals("welcome"))

return SUCCESS;

else

return ERROR;

}

}

在struts.xml文件中通过属性 值在result中配置表达式实现动态跳转
