Spring bean初始化采用多arg方法

Question

我想创建以下Spring bean(一个JMX监视器),它具有方法 setThresholds(Number highThreshold,Number lowThreshold).

我可以在配置中调用方法(带有两个参数)吗？我不想编写代码来调用它.

<bean id="myMonitor" class="javax.management.monitor.GaugeMonitor" init-method="start">
  <property name="observedObject">
    <bean class="javax.management.ObjectName">
      <constructor-arg value="test.jmx:name=testBean1" />
    </bean>
  </property>
  <property name="observedAttribute" value="testProperty" />
  <property name="granularityPeriod">
    <bean class="java.lang.Float">
      <constructor-arg value="1000" />
    </bean>
  </property>
</bean>

可以通过使用MethodInvokingFactoryBean(Spring 4.x和5.x)(这不是我的想法,我只是在这个论坛找到它:http://forum.springsource.org/archive/index.php/t-16354 .html)

SomeClass someobject = new SomeClass();
someobject.set("String1","String2");

<bean id="someobject" class="SomeClass" />

<bean class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
    <property name="targetObject" ref="someobject">
    <property name="targetMethod" value="set">
    <property name="arguments">
        <list>
            <value>String1</value>
            <value>String2</value>
        </list>
    </property>
</bean>
