First, write a class and annotate it:<\/p>\n
package com.javatutor.spring.jmx;<\/p>\n
import java.util.HashMap;<\/p>\n
import java.util.Map;<\/p>\n
import org.springframework.jmx.export.annotation.ManagedAttribute;<\/p>\n
import org.springframework.jmx.export.annotation.ManagedOperation;<\/p>\n
import org.springframework.jmx.export.annotation.ManagedResource;<\/p>\n
@ManagedResource( objectName = "com.javatutor.spring.jmx:name=StringMap" )<\/p>\n
public class StringMapImpl<\/p>\n
{<\/p>\n
private Map<String, String> map = new HashMap<String, String>();<\/p>\n
@ManagedAttribute<\/p>\n
public int getSize()<\/p>\n
{<\/p>\n
return map.size();<\/p>\n
}<\/p>\n
@ManagedOperation<\/p>\n
public String get( String key )<\/p>\n
{<\/p>\n
return map.get( key );<\/p>\n
}<\/p>\n
@ManagedOperation<\/p>\n
public String put( String key, String value )<\/p>\n
{<\/p>\n
return map.put( key, value );<\/p>\n
}<\/p>\n
public void remove( String key )<\/p>\n
{<\/p>\n
map.remove( key );<\/p>\n
}<\/p>\n
}<\/p>\n
Next, write a spring config file:<\/p>\n
<?xml version="1.0" encoding="UTF-8"?><\/p>\n
<!DOCTYPE beans PUBLIC "-\/\/SPRING\/\/DTD BEAN\/\/EN"<\/p>\n
"http:\/\/www.springframework.org\/dtd\/spring-beans.dtd"><\/p>\n
<beans><\/p>\n
<bean id="StringMap" class="com.javatutor.spring.jmx.StringMapImpl" \/><\/p>\n
<bean id="MBeanExporter"<\/p>\n
class="org.springframework.jmx.export.MBeanExporter"><\/p>\n
<property name="assembler" ref="MBeanInfoAssembler" \/><\/p>\n
<property name="autodetect" value="true" \/><\/p>\n
<property name="namingStrategy" ref="NamingStrategy" \/><\/p>\n
<\/bean><\/p>\n
<bean id="AnnotationJmxAttributeSource"<\/p>\n
class="org.springframework.jmx.export.annotation.AnnotationJmxAttributeSource"<\/p>\n
\/><\/p>\n
<bean id="NamingStrategy"<\/p>\n
class="org.springframework.jmx.export.naming.MetadataNamingStrategy"><\/p>\n
<property name="attributeSource" ref="AnnotationJmxAttributeSource" \/><\/p>\n
<\/bean><\/p>\n
<bean id="MBeanInfoAssembler"<\/p>\n
class="org.springframework.jmx.export.assembler.MetadataMBeanInfoAssembler"><\/p>\n
<property name="attributeSource" ref="AnnotationJmxAttributeSource" \/><\/p>\n
<\/bean><\/p>\n
<\/beans><\/p>\n
Now the client:<\/p>\n
package com.javatutor;<\/p>\n
import javax.swing.JOptionPane;<\/p>\n
import org.springframework.context.ApplicationContext;<\/p>\n
import org.springframework.context.support.ClassPathXmlApplicationContext;<\/p>\n
import com.javatutor.spring.jmx.StringMapImpl;<\/p>\n
public class SpringWithJmxExample<\/p>\n
{<\/p>\n
public static void main( String[] args )<\/p>\n
{<\/p>\n
ApplicationContext beFac = new ClassPathXmlApplicationContext( "springJmx.xml"<\/p>\n
);<\/p>\n
StringMapImpl cacheBean = (StringMapImpl) beFac.getBean( "StringMap" );<\/p>\n
cacheBean.put( "Key", "Value" );<\/p>\n
System.out.println( cacheBean.get("Key") );<\/p>\n
JOptionPane.showMessageDialog( null, "End" );<\/p>\n
}<\/p>\n
}<\/p>\n
Start the program. Do not forgett to start with -Dcom.sun.management.jmxremote.
Start JConsole and enjoy.<\/p>\n
