关于在以下应用程序中添加spring jmx功能

Question

我是JMX世界的新手，到目前为止我已经探索过它主要用于监视和管理应用程序，因为我对spring JMX非常感兴趣，我已经开发了这个接口和类， 你能告诉我如何特别是对于JMX特别适用于弹簧，需要在spring xml中进行哪些设置 ...

package dustin.jmx.modelmbeans;

/**
 * Interface to expose Model MBean via Spring.
 */
public interface SimpleCalculatorIf
{
   public int add(final int augend, final int addend);

   public int subtract(final int minuend, final int subtrahend);

   public int multiply(final int factor1, final int factor2);

   public double divide(final int dividend, final int divisor);
} 

以下是班级..

package dustin.jmx.modelmbeans;


public class SimpleCalculator implements SimpleCalculatorIf
{
   /**
    * Calculate the sum of the augend and the addend.
    *
    * @param augend First integer to be added.
    * @param addend Second integer to be added.
    * @return Sum of augend and addend.
    */
   public int add(final int augend, final int addend)
   {
      return augend + addend;
   }

   /**
    * Calculate the difference between the minuend and subtrahend.
    * 
    * @param minuend Minuend in subtraction operation.
    * @param subtrahend Subtrahend in subtraction operation.
    * @return Difference of minuend and subtrahend.
    */
   public int subtract(final int minuend, final int subtrahend)
   {
      return minuend - subtrahend;
   }

   /**
    * Calculate the product of the two provided factors.
    *
    * @param factor1 First integer factor.
    * @param factor2 Second integer factor.
    * @return Product of provided factors.
    */
   public int multiply(final int factor1, final int factor2)
   {
      return factor1 * factor2;
   }

   /**
    * Calculate the quotient of the dividend divided by the divisor.
    *
    * @param dividend Integer dividend.
    * @param divisor Integer divisor.
    * @return Quotient of dividend divided by divisor.
    */
   public double divide(final int dividend, final int divisor)
   {
      return dividend / divisor;
   }
}

Answer 1

1）将SimpleCalculatorIf重命名为SimpleCalculatorMBean。 然后，context.xml中的这两行就足以让Spring检测并将你的SimpleCalculator注册为MBean http://docs.oracle.com/javase/tutorial/jmx/mbeans/standard.html

<context:mbean-export/>
<bean class="dustin.jmx.modelmbeans.SimpleCalculator"/>

2）但最有效的方法是使用Spring注释，然后你甚至不需要一个接口

@ManagedResource(objectName="bean:name=SimpleCalculator", description="My Managed Calculator", log=true,
logFile="jmx.log", currencyTimeLimit=15, persistPolicy="OnUpdate", persistPeriod=200,
persistLocation="foo", persistName="bar")
public class SimpleCalculator implements SimpleCalculatorIf
{
   @ManagedOperation
   public int add(final int augend, final int addend)
   {
      return augend + addend;
   }
   ...

实际默认@ManagedResource没有param也可以工作，我只是想显示你有多少注释选项。 阅读Spring文档中的更多内容
