用于生成JSON分层路径的Java代码

Question

我正在开发一个项目，我需要在Java中解析JSON并显示JSON密钥/节点的分层路径，如下所述。

我正在使用Jackson API在Java中开发此程序，但我无法获得任何现成的API，这将返回JSON当前键/节点的分层路径。

JSON数据 -

{“tomcat-users”:
    {
        “role”:[
            {“@rolename”:”manager-gui”},
            {“@rolename”:”manager-script”},
            {“@rolename”:”manager-jmx”},
            {“@rolename”:”manager-status”}
        ],
        ”user”:{
            “@username”:”admin”,
            ”@roles”:”manager-gui,manager-script”,
            ”@password”:”admin”
        }
    }
}

输出应该像 -

Column 1                                        Column 2
---------------------------------------------------------------------------
tomcat-users -> role[1] -> @rolename            manager-gui
tomcat-users -> role[2] -> @rolename            manager-script
tomcat-users -> role[3] -> @rolename            manager-jmx
tomcat-users -> role[4] -> @rolename            manager-status
tomcat-users -> user -> @username               admin
tomcat-users -> user -> @roles                  manager-gui,manager-script
tomcat-users -> user -> @password               admin

任何人都可以告诉我，他们的任何API是否会让我回到原点？

我的Java代码 -

public static void generateJsonPath(JsonNode node) {
     Iterator<String> fieldNames = node.getFieldNames();
     while(fieldNames.hasNext()){
         String fieldName = fieldNames.next();
         JsonNode fieldValue = node.get(fieldName);
         if (fieldValue.isObject()) {
            System.out.println(fieldName + " -> ");
            generateJsonPath(fieldValue);
         } else if(fieldValue.isArray()) {
             System.out.println(fieldName + " -> ");
             Iterator<?> iterator = fieldValue.getElements();
             while(iterator.hasNext()) {
                 generateJsonPath((JsonNode) iterator.next());
             }
         } else {
            String value = fieldValue.asText();
            System.out.println(fieldName + " : " + value);
         }
     }
}

Java代码结果 -

tomcat-users -> 
role -> 
@rolename : manager-gui
@rolename : manager-script
@rolename : manager-jmx
@rolename : manager-status
user -> 
@username : root
@password : root
@roles : manager-gui,manager-script,manager-jmx,manager-status
