Enabling JMX in Spring Boot - spring-boot

Question

Here is my build.gradle...
dependencies {
compile('org.springframework.boot:spring-boot-starter-parent:2.0.1.RELEASE')
compile('org.springframework.boot:spring-boot-starter-batch')
compile("org.springframework.boot:spring-boot-starter-jdbc")
compile("org.springframework.boot:spring-boot-starter-web")
compile("com.h2database:h2")
testCompile('org.springframework.boot:spring-boot-starter-test')
testCompile('org.springframework.batch:spring-batch-test')
}
Which I thought would enable JMX by default. I go to JConsole, connect to the application and expect to see a org.springframework.boot folder under java.util.logging, I see nothing.
So, now I pick a few of my custom beans and add #ManagedResource, I know see these.
However, what if I want to expose spring batch beans like #JobOperator how do I do this?
Pre Spring Boot, I could so something like:
<bean class="org.springframework.jmx.export.MBeanExporter">
<property name="beans">
<map>
<entry key="spring:service=batch,bean=jobOperator">
<bean class="org.springframework.aop.framework.ProxyFactoryBean">
<property name="target" ref="jobOperator"/>
<property name="interceptorNames" value="exceptionTranslator" />
</bean>
</entry>
</map>
</property>
<property name="assembler">
<bean class="org.springframework.jmx.export.assembler.InterfaceBasedMBeanInfoAssembler">
<property name="interfaceMappings">
<map>
<entry key="spring:service=batch,bean=jobOperator"
value="org.springframework.batch.core.launch.JobOperator"/>
</map>
</property>
</bean>
</property>
</bean>
When I define my JobOperator, in my #Configuration file in Spring Boot I do:
#Bean
public JobOperator jobOperator() throws Exception {
SimpleJobOperator simpleJobOperator = new SimpleJobOperator();
// the operator wraps the launcher
simpleJobOperator.setJobLauncher(this.jobLauncher);
...
}
I can't add #ManagedResource under the #Bean annotation. So how do I expose the JobOperator as a JMX bean?

Answer 1

Here is how i did it in my code -
#Bean
public MBeanExporter exporter(){
MBeanExporter m = new MBeanExporter();
Map<String,Object> map = new HashMap<String, Object>();
JmxBean testBean = (JmxBean)ctx.getBean("testBean");
map.put("testBean",testBean);
m.setBeans(map);
return m;
}
#Bean
public JmxBean testBean(){
return new JmxBean("test",100);
}
In your case since you want to register jobOperator, just replace testBean in exporter bean with it.
