Java 从mule esb向主程序传递参数

我有一个简单的java程序，要执行main方法。执行时，我需要传递一些参数，如下所示：

class Main{
    public static void main(String[] args) {
        initializeBaseClass();
}

以以下方式运行上述程序：

java -classpath C;/test/sample.jar -mainClass com.test.SampleTest

它执行并成功运行

现在我需要从Mule esb运行相同的程序。 哪种方法是调用此方法并从mule esb执行的最佳方法

我尝试过添加java组件和添加属性键/值，但没有效果。如何从mule传递参数？

使用Spring、脚本语言或MEL有更好的方法吗？

为什么不在组件中使用Mulestdio在Mule studio中获取输入。。。例如：-在骡流中：-

    <spring:beans>
        <spring:bean id="transmission" class="com.test.InvokeMain"/>
    </spring:beans>
    <flow name="test" ...
       <set-payload value="-mainclass com.test.Abcd -driver org.hsqldb.jdbc.JDBCDriver/>
       <invoke object-ref="transmission" method="invoke" methodArgumentTypes="java.lang.String" methodArguments="#[payload]" name="transmissionAPI"/>
    </flow>

<?xml version="1.0" encoding="UTF-8"?>

现在，您可以根据需要修改java类以处理输入消息，并可以在运行Mule应用程序后使用Mule stdio组件获取输入

这看起来像
