1、项目结构如下：
2、com.sxl.pojos==》Student.java
package com.sxl.pojos;
public class Student {
private int sid;
private String name;
private String pass;
public int getSid() {
return sid;
}
public void setSid(int sid) {
this.sid = sid;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPass() {
return pass;
}
public void setPass(String pass) {
this.pass = pass;
}
}
3、
package com.sxl.dao;
import com.sxl.pojos.Student;
public class StudentDao {
public boolean addStudent(Student s) {
System.out.println("添加学生啊："+s.getSid()+";"+s.getName()+";"+s.getPass());
return false;
}
}
4、
package com.sxl.service; import com.sxl.dao.StudentDao; import com.sxl.pojos.Student; public class StudentService { private StudentDao mydao; public StudentService() { //dao=new StudentDao(); } public boolean addUser(Student stu) { mydao.addStudent(stu); return false; } //IOC注入：1.set方式。2.构造函数方式 public StudentDao getMydao() { return mydao; } public void setMydao(StudentDao mydao) { this.mydao = mydao; } }
5、
package com.sxl.tests; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import com.sxl.pojos.*; import com.sxl.service.StudentService; public class TestSpring { /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub ApplicationContext context=new ClassPathXmlApplicationContext("applicationContext.xml"); Student s=(Student) context.getBean("stu"); s.setSid(1); s.setName("aaa"); s.setPass("123"); StudentService ss=(StudentService) context.getBean("service"); ss.addUser(s); Student s2=(Student) context.getBean("stu"); s2.setSid(2); s2.setName("vvv"); s2.setPass("123"); System.out.println(s.getSid()+";"+s.getName()+","+s.getPass()); System.out.println(s2.getSid()+";"+s2.getName()+","+s2.getPass()); } }
