Setter注入

【例】通过Setter注入为User属性赋值

package com.shw;
public class User {
	private String username;
	private String password;
	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;
	}
}

配置applicationContext.xml

<bean id="user" class="com.shw.User">
	<property name="username">
		<value>张三</value>
	</property>
	<property name="password">
		<value>123456</value>
	</property>
</bean>

创建测试类

public static void main(String[] args) {
		//加载applicationContext.xml
		ApplicationContext context=new ClassPathXmlApplicationContext("applicationContext.xml");
		//获取实例
		User user=(User) context.getBean("user");
		//调用方法
		System.out.println("用户名:"+user.getUsername());
		System.out.println("密码:"+user.getPassword());
	}

运行结果：
