Spring JMX代理接口問題

[英]Spring JMX proxy interface issue

 原文  2014-11-11 20:09:19  8   1    spring/ jmx/ spring-jmx/ mbeanexporter

問題描述

我正在我的項目中嘗試Spring + JMX bean配置。 我是JMX技術的新手。 我需要在托管bean中實現proxyinterface方式。 嘗試時，出現以下錯誤。

誰能指導我？ 我正在嘗試在Tomcat中部署戰爭。 關於啟動時應用程序的上下文初始化，我得到了InvalidInvocationException

接口 

package my.pjt.test.location;

public interface AppResourceLocationMBean {

    String getLocation();

    void setLocation(String location);
}

實施班 

package my.pjt.test.location;

public class AppResourceLocation implements AppResourceLocationMBean {

    private volatile String location = "classpath:**/app-resource/**/";

    @Override public String getLocation() {
        return location;
    }

    @Override public void setLocation(String location) {
        this.location = location;
    }
}

在AppLoader中使用 

package my.pjt.test.location;

public class AppLoader {

    private volatile AppResourceLocationMBean appLocationMBean;

     public void init() throws Exception {
        ...........
        String appLocation = this.appLocationMBean.getLocation();
        ..........  
    }
}

編輯：我仍然面臨問題。 我在https://github.com/appu-86/JMX-Test中創建了一個示例項目。 任何人都可以幫助/提示我示例項目中的代理接口問題是什么原因？

1 個解決方案

嘗試您的樣品； 當我按照建議添加throws OperationException ，我得到... 

Caused by: javax.management.InstanceNotFoundException: test:name=appLocationConfiguration,type=SpringAppLocationConfiguration,context=pjt001

此評論沒有任何意義： 

<!-- Enabling below bean and disabling the above bean worked for me. But need a proxy interface solution. -->

該代理是真實MBean的代理 ，不能代替它-MBean必須存在於服務器中。

沒有這樣的MBean“ test：name = appLocationConfiguration，type = SpringAppLocationConfiguration，context = pjt001”-您可以通過打開VisualVM或JConsole看到這一點。

但是，即使定義了MBean，問題的根本原因是，您試圖在加載上下文之前從init()方法訪問它。

這是測試上下文的修訂版，可以正常工作，因為我刪除了MBeanExporter中對apploader的引用，並將appLoader移至MBeanExporter下方。 

<bean id="mbeanServer" class="org.springframework.jmx.support.MBeanServerFactoryBean">
    <property name="locateExistingServerIfPossible" value="true"></property>
</bean>


<bean id="appConfigLocationMBean" class="org.springframework.jmx.access.MBeanProxyFactoryBean">
    <property name="objectName" value="test:name=appLocationConfiguration,type=SpringAppLocationConfiguration,context=pjt001"/>
    <property name="proxyInterface" value="com.my.config.app_loader.AppResourceLocationMBean"/>
</bean>

<!-- Enabling below bean and disabling the above bean worked for me. But need a proxy interface solution. -->
<bean id="actualAppConfigLocationMBean" class="com.my.config.app_loader.AppResourceLocation"/>       

 <bean id="mbeanExporter" class="org.springframework.jmx.export.MBeanExporter">
    <property name="beans">
      <map>
    <!--  Used to add additional application contexts at runtime. --> 
       <entry key="test:name=appLocationConfiguration,type=SpringAppLocationConfiguration,context=pjt001"
              value-ref="actualAppConfigLocationMBean" />
      </map>
    </property>

</bean>

<bean id="appLoader" class="com.my.config.app_loader.AppLoader">
    <property name="appLocationMBean" ref="appConfigLocationMBean" />
</bean>

但是，我建議實現SmartLifecycle並在start()而不是init()進行查找，因為這樣可以確保上下文中的所有bean均已初始化。
