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();
}
}
