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
