Spring中Bean的生命周期3

下面来介绍一下Spring种Bean的销毁。销毁的方法和初时化的方法非常的类似：
完成Bean的销毁也有两种方式;
1在配置文件种指定destroy-method属性来完成
2Bean类实现org.springframework.beans.factory.DsiposableBean
下面看一下代码

package com.jnotnull;

public class HelloWorld {
public String message = null;

        public String cleanup() {
this.message="";
}

public String getMessage() {
return message;
}

public void setMessage(String message) {
this.message = message;
}

}


<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans Public "-//SPRING//DTD BEAN//EN"
"http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<bean id ="HelloWorld" class="com.jnotnull.HelloWorld" destory-method="cleanup">
<bean>
</beans>


第二种，实现DisposableBean接口

package com.jnotnull;
import org.springframework.beans.factory.DisposableBean;

public class HelloWorld implements DisposableBean{
public String message = null;

        public void destroy(){
                this.message = "";
        }

public String getMessage() {
return message;
}

public void setMessage(String message) {
this.message = message;
}

}
