Question

我正在编写一个工具来验证Web应用程序的WebSphere设置。我希望能够通过java AdminClient对象远程连接到服务器来查找WebSphere变量（所有范围）的所有可能值。我已经阅读了another post about this，虽然我认为我现在拥有正确的代码但是我无法使用AdminOperations MBean，因为我必须使用的WebSphere帐户未被授予管理员权限。我想知道是否有办法在不使用AdminOperations的情况下解析WebSphere变量。谢谢！

到目前为止，这是我的代码（再次，由于权限问题而无效）：

private static String expandVariable(AdminClient client, String s)
    throws Exception 
{ 
    Set result = client.queryNames(new ObjectName("*:*,type=AdminOperations,process=exampleProcess"), null);

    return (String)client.invoke((javax.management.ObjectName) 
    result.iterator().next(),"expandVariable",new Object[] 
    {"${"+s+"}"}, new String[] {"java.lang.String"});

}

具有Monitor角色的用户可以使用ConfigService的queryConfigObjects API和其他配置服务API来从配置（而非运行时）访问变量。

示例摘录如下：

        //name of variable that needs to be expanded
        String varName ="DERBY_JDBC_DRIVER_PATH";
        //create a configservice proxy
        configService = new ConfigServiceProxy(adminClient);
        //create a session
        Session session = new Session();
        //ObjectName for the variables.xml
        ObjectName varMapObjName = ConfigServiceHelper.createObjectName(null, "VariableMap", null);
        //query all variables.xml under cell.scope is null
        ObjectName[] variableMaps = configService.queryConfigObjects(session, null, varMapObjName, null);

        for (int i = 0; i < variableMaps.length; i++) {
            ObjectName varMap = (ObjectName) variableMaps[i];
            //retrieve each variable entry
            AttributeList varEntries = configService.getAttributes(session, varMap, new String[]{"entries"}, false);
            List entryList = (List) ConfigServiceHelper.getAttributeValue(varEntries, "entries");
            //Iterate through each entry and get the value for the specified variable(symbolicName) name.
            for (int j = 0; j < entryList.size(); j++) {
                ObjectName varObj = (ObjectName)entryList.get(j);
                String symbolicName=  (String)configService.getAttribute(session, varObj, "symbolicName");
                String value = null;
                if (symbolicName.equals(varName)){
                    value= (String)configService.getAttribute(session, varObj, "value");
                    System.out.println(symbolicName+"="+value);
                }
            }
        }

是否可以使用没有AdminOperations的java AdminClient访问WebSphere变量？
