破坏-当我的猫关闭时，春豆的方法不会被调用。

Question

当我的应用程序被关闭以防止tomcat停止时，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上下文是通过ContextLoaderListener在web.xml中加载的，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雇员bean：

Employee.class

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tomcat时，我可以看到我的init方法正在被调用，但不幸的是，当我停止tomcat时，关闭()，即破坏方法没有被调用。

我正在使用Spring3.1.2发行版jars。

我做错了什么？

Answer 1

谢谢安德烈。+1给你。问题是我没有正确地关闭。现在，在阅读了一些文档之后，我发现，如果我从tomcat或使用诸如(Simpldwan.sh/ shutdown . that )之类的关闭脚本来优雅地关闭我的Tomcat，那么我的破坏方法就会被调用。

杀死-9命令将无法工作，而且如果试图停止eclipse，它也不起作用。
