Converting XML Spring config for JMX to Java config
I have a small test app for exposing a "Bean" to JMX using Spring. It uses an XML based config and everything works fine:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd">
<context:component-scan base-package="com.dmclaughlin.spring" />
<context:property-placeholder location="classpath:test.properties"/>
<bean id="SimpleJmxController" class="com.dmclaughlin.spring.jmx.SimpleJmxBean">
<property name="activated" value="${some.activated}"/>
</bean>
<!-- Spring JMX -->
<bean id="exporter" class="org.springframework.jmx.export.MBeanExporter" lazy-init="false">开发者_StackOverflow中文版
<property name="autodetect" value="true"></property>
<property name="namingStrategy" ref="namingStrategy"></property>
<property name="assembler" ref="assembler"></property>
</bean>
<bean id="attributeSource"
class="org.springframework.jmx.export.annotation.AnnotationJmxAttributeSource"/>
<bean id="assembler"
class="org.springframework.jmx.export.assembler.MetadataMBeanInfoAssembler">
<property name="attributeSource" ref="attributeSource"/>
</bean>
<bean id="namingStrategy"
class="org.springframework.jmx.export.naming.MetadataNamingStrategy">
<property name="attributeSource" ref="attributeSource"/>
</bean>
But the application I need to add this functionality to, uses @Configuration style, and I'm trying to convert the above XML to work. I added something like this:
@Bean
public MetadataNamingStrategy getNamingStrategy() {
MetadataNamingStrategy strategy = new MetadataNamingStrategy();
strategy.setAttributeSource(new AnnotationJmxAttributeSource());
return strategy;
}
@Bean
public MetadataMBeanInfoAssembler getMbeanInfoAssembler() {
return new MetadataMBeanInfoAssembler(new AnnotationJmxAttributeSource());
}
@Bean
public MBeanExporter getExporter() {
MBeanExporter exporter = new MBeanExporter();
exporter.setAutodetect(true);
exporter.setNamingStrategy(getNamingStrategy());
exporter.setAssembler(getMbeanInfoAssembler());
return exporter;
}
And everything compiles, but when I load up JConsole my Bean annotated with @ManagedResource and @ManagedAttribute isn't exposed. Am I missing something simple here?
Edit: the answer below didn't fix my problem (the problem was I was testing my XML in a Tomcat environment, but testing my non-XML config in a standalone application, which meant there was no JMXServer present.. d'oh), but it did help me simplify once I debugged what I messed up.
For me it was enough to add:
@Bean
public AnnotationMBeanExporter annotationMBeanExporter() {
return new AnnotationMBeanExporter();
}
you should configure your mbeanexporter with "eager"
@Bean
@Lazy(false)
public MBeanExporter getExporter() {
...
}
