直接看实例：

Users.java

package cn.iborder.entity;import cn.iborder.logging.MyLog;public class Users {	private Integer id;	private String username;	private String password;	private String name;		public Users(){		System.out.println(MyLog.showLog(this)+"无参构造函数，Users对象创建"+this);	}		public Users(Integer id,String username,String password,String name){		System.out.println(MyLog.showLog(this)+"有参构造函数，Users对象创建"+this);		this.id = id;		this.username = username;		this.password = password;		this.name = name;	}		public Integer getId() {		return id;	}	public void setId(Integer id) {		this.id = id;	}	public String getUsername() {		return username;	}		public void setUsername(String username) {		this.username = username;	}		public String getPassword() {		return password;	}		public void setPassword(String password) {		this.password = password;	}		public String getName() {		return name;	}		public void setName(String name) {		this.name = name;	}		@Override	public String toString() {		return "Users [id=" + id + ", username=" + username + ", password=" + password + ", name=" + name + "]";	}		public void init() {		System.out.println(MyLog.showLog(this)+"对象创建时调用"+this);	}		public void destory() {		System.out.println(MyLog.showLog(this)+"对象销毁时调用"+this);	}	}

BeanFactory.java

package cn.iborder.factory;import cn.iborder.entity.Users;public class BeanFactory {		public Users getInstance() {		return new Users(3, "baidu", "baidupass", "baiduname");	}		public static Users getStaticInstance() {		return new Users(4, "sina", "sinapass", "sinaname");	}}

applicationContext.xml

applicationContext.xml中给bean对象属性注入值（依赖注入）

1、通过构造函数注入

具体看上面applicationContext.xml配置文件

2、通过setter方法注入值

具体看上面applicationContext.xml配置文件

3、P名称空间注入值

示例

4、自动装配(不推荐使用)

5、注解
