java - 当我的 tomcat 关闭时，没有调用 spring bean 的销毁方法

Question

当我的应用程序因 tomcat 停止而关闭时，我无法找到为什么我的 destroy-method 没有被调用的原因。

我有一个 Web 应用程序，spring 上下文通过 web.xml 中的 ContextLoaderListener 加载，如下所示:

web.xml

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:appContext.xml</param-value>
</context-param>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

下面是我的应用程序中的一个 Employee bean:

员工类

public class Employee {
    String eName;
    long eSal;
    public String getEName() {
        return eName;
    }
    public void setEName(String name) {
        eName = name;
    }
    public long getESal() {
        return eSal;
    }
    public void setESal(long sal) {
        eSal = sal;
    }

    public void init() {
        System.out.println("Initiaizing...");
        System.out.println("eName: " + eName + " - eSal: " + eSal);
    }

    public void close() {
        System.out.println("Destroying...");
    }
}

bean 是在我的应用程序上下文文件中定义的，如下所示:

appContext.xml

<beans:beans xmlns="http://www.springframework.org/schema/integration"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:beans="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
            http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
            http://www.springframework.org/schema/context
            http://www.springframework.org/schema/context/spring-context-3.1.xsd">

    <beans:bean id="employee" class="com.test.Employee" init-method="init" destroy-method="close">
        <beans:property name="eName" value="sandip" />
        <beans:property name="eSal" value="80000" />
    </beans:bean>        
</beans:beans>

当我启动我的 tomcat 时，我可以看到我的 init 方法被调用，但不幸的是，当我停止 tomcat 时，close() 即 destroy 方法没有被调用。

我正在使用 spring 3.1.2 分发 jar 。

我做错了什么？

Answer 1

谢谢安德烈。 +1 给你。问题是我没有正常关机。现在，在阅读了一些文档后，我发现如果我从 Tomcat 管理器或使用关闭脚本(如(shutdwon.sh/shutdown.bat))优雅地关闭我的 tomcat，我的 destroy 方法将被调用。

Kill -9 命令将不起作用，而且如果试图从 eclipse 中停止，它也不起作用。
