获取 mbean 属性值树

Question

我使用 JMX 从服务器获取 mbeans 值（weblogic JMS 配置）

不同的属性有不同的返回类型：

Ljavax.management.ObjectName;
javax.management.ObjectName
Ljava.lang.String;

对于每个返回值列表的属性，我在我的代码中循环 for/if/else。

最后是非常嵌套的代码。有更好的办法吗？

我自己做。它对我有用public static void parser(String javaxExcept, String LjavaxExcept, HashMap < String, Object > [] atrs, ObjectName ObjUrl, int ng, ObjectName[] origObjUrl) throws Exception {&nbsp; &nbsp; if (ng > 20) {&nbsp; &nbsp; &nbsp; &nbsp; System.out.println("Possibly loop detected");&nbsp; &nbsp; &nbsp; &nbsp; for (int t = 0; t < origObjUrl.length; t++) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; System.out.println(origObjUrl[t]);&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; System.exit(1);&nbsp; &nbsp; }&nbsp; &nbsp; origObjUrl[ng] = ObjUrl;&nbsp; &nbsp; MBeanAttributeInfo[] attributes = (connection.getMBeanInfo(ObjUrl)).getAttributes();&nbsp;
