spring随手笔记3：销毁方法

1.

 public class HelloWorld {
     private String msg;
     public void setMsg(String msg) {
         this.msg = msg;
     }
     public String getMsg() {
         return msg;
     }
     public void detory(){
         this.msg="";
     }
 }

<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="";
    }

}
