User类：
package com.colorlight.springscope;
public****class User {
private****intid;
private String name;
private String password;
public User(){
System.out.println("创建了User的实例!");
}
public****int getId() {
returnid;
}
public****void setId(int id) {
this.id = id;
}
public String getName() {
returnname;
}
public****void setName(String name) {
this.name = name;
}
public String getPassword() {
returnpassword;
}
public****void setPassword(String password) {
this.password = password;
}
}
测试类：
package com.colorlight.springscope;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public****class MainTest {
ApplicationContext ac = new ClassPathXmlApplicationContext(
"applicationContext.xml", this.getClass());
// 单例
@Test
public****void test1() {
System.out.println("在getBean()调用之前");
User user1 = (User) ac.getBean("user1");
User user2 = (User) ac.getBean("user1");
System.out.println(user1 != null);
System.out.println(user1 == user2);
}
// 多例
@Test
public****void test2() {
System.out.println("在getBean()调用之前");
User user1 = (User) ac.getBean("user2");
User user2 = (User) ac.getBean("user2");
System.out.println(user1 != null);
System.out.println(user1 == user2);
}
}
