spring随手笔记3：销毁方法

 1 public class HelloWorld {
 2     private String msg;
 3     public void setMsg(String msg) {
 4         this.msg = msg;
 5     }
 6     public String getMsg() {
 7         return msg;
 8     }
 9     public void detory(){
10         this.msg="";
11     }
12 }

<bean id="HelloWord" class="com.ltf.captha.serviceImpl.HelloWorld" destroy-method="destory">
        <property name="msg">
            <value>helloworld</value>
        </property>
    </bean>

2. 实现org.springframework.beans.factory.DisposableBean中的destory方法

public class HelloWorld implements DisposableBean{
    private String msg;
    public void setMsg(String msg) {
        this.msg = msg;
    }
    public String getMsg() {
        return msg;
    }
    public void destroy() throws Exception {
        this.msg="";
    }
    
}
