一、新建web项目

结构
在这里插入图片描述

一、代码及配置

Action类：

package net.amiba.action;

import com.opensymphony.xwork2.ActionSupport;
import net.amiba.bean.Emp;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;

import java.util.ArrayList;
import java.util.List;


@Controller
@Scope("prototype")
public class EmpAction extends ActionSupport {
    private List<Emp> empList;

    public List<Emp> getEmpList() {
        return empList;
    }

    public void setEmpList(List<Emp> empList) {
        this.empList = empList;
    }

    @Override
    public String execute() throws Exception {
        empList = new ArrayList<>();

        empList.add(new Emp(9527,"zxc"));
        empList.add(new Emp(9528,"zxx"));
        empList.add(new Emp(9529,"amiba"));

        return SUCCESS;
    }
}

Emp类：

package net.amiba.bean;

public class Emp {
    private Integer empno;
    private String ename;

    public Emp() {
    }

    public Emp(Integer empno, String ename) {
        this.empno = empno;
        this.ename = ename;
    }

    public Integer getEmpno() {
        return empno;
    }

    public void setEmpno(Integer empno) {
        this.empno = empno;
    }

    public String getEname() {
        return ename;
    }

    public void setEname(String ename) {
        this.ename = ename;
    }

    @Override
    public String toString() {
        return "Emp{" +
                "empno=" + empno +
                ", ename=" + ename +
                '}';
    }
}
