action接受参数三种方法

package com.lsp.action;

import com.opensymphony.xwork2.ActionSupport;

/**
 * ----------------这里是Action添加成员属性接受参数--------------
 */
public class Action1 extends ActionSupport {
    private int id;
    private String name;

    public String test1() {
        System.out.println("name" + name);
        System.out.println("id" + id);
        return "test1";
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

package com.lsp.action;

import com.lsp.entity.User;
