?本例之通過Action調Service，Service掉Dao實現(主要掌握思想，注意Date的注入，以及javaBean的前臺顯示)

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