Spring 框架的搭建及测试

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、com.sxl.dao==》StudentDao.java

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、com.sxl.service==》StudentService.java

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、com.sxl.tests==》TestSpring.java

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());
    }
}

6、配置文件：applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans
    xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:p="http://www.springframework.org/schema/p"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">

     <bean id="stu" class="com.sxl.pojos.Student" scope="prototype"></bean>

     <bean id="dao" class="com.sxl.dao.StudentDao"></bean>

     <bean id="service" class="com.sxl.service.StudentService">
        <property name="mydao" ref="dao"></property>
     </bean>
</beans>

7、测试结果：
