Struts2.3+Spring4.0

本例之通过Action调Service，Service掉Dao实现(主要掌握思想，注意Date的注入，以及javaBean的前台显示)

StudentAction-->StudentService-->StudentDao-->Student

Student.java

package cn.itcast.domain;

import java.util.Date;

public class Student {
    private Integer id;
    private String name;
    private String sex;
    private Date birthday;
    public Date getBirthday() {
        return birthday;
    }

    public void setBirthday(Date birthday) {
        this.birthday = birthday;
    }

    public Integer getId() {
        return id;
    }

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

    public String getName() {
        return name;
    }

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

    public String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }

    @Override
    public String toString() {
        return "Student [id=" + id + ", name=" + name + ", sex=" + sex
                + ", birthday=" + birthday + "]";
    }

}

StudentDao.java

package cn.itcast.dao;

import cn.itcast.domain.Student;

public class StudentDao {
    private Student student;

    public Student getStudent() {
        return student;
    }

    public void setStudent(Student student) {
        this.student = student;
    }

}

StudentService.java

package cn.itcast.service;

import cn.itcast.dao.StudentDao;
import cn.itcast.domain.Student;

public class StudentService {
    private StudentDao studentDao;

    public StudentDao getStudentDao() {
        return studentDao;
    }

    public void setStudentDao(StudentDao studentDao) {
        this.studentDao = studentDao;
    }

    public Student getStudent() {
        return studentDao.getStudent();
    }
}

StudentAction.java

package cn.itcast.web.action;

import cn.itcast.domain.Student;
import cn.itcast.service.StudentService;

import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;

public class StudentAction extends ActionSupport {
    private static final long serialVersionUID = 1L;
    private StudentService studentService;

    public StudentService getStudentService() {
        return studentService;
    }

    public void setStudentService(StudentService studentService) {
        this.studentService = studentService;
    }

    @Override
    public String execute() throws Exception {
        Student student = studentService.getStudent();
        System.out.println(student);
        ActionContext.getContext().getSession().put("student", student);
        return super.execute();
    }
}
