Question

我正在使用jsonschema2pojo-maven-plugin v0.4.7从JSON模式生成POJO类。我想要获取动态生成的pojo类的属性。包含onather pojo类的pojo类。是否有从包含onather的pojo类中读取字段的解决方案？例如，在这种情况下，我有Employee pojo，因为我想要获取两个类的字段的Address对象。

下面是我的架构

    {
     "$schema": "http://json-schema.org/draft-04/schema#",
     "type": "object",
     "title":"Employee",
     "name":"Employee",
     "properties": {
     "empId": {
      "type": "integer"
    },
    "lastName": {
      "type": "string"
    },
    "title": {
      "type": "string"
    },
    "salary": {
      "type": "integer"
    },
    "address": {
      "type": "object",
      "properties": {

        "city": {
          "type": "string"
        },
        "pincode": {
          "type": "integer"
        },
        "landMark":{
        "type": "string"
        }
     }

    },
    "phoneNo": {
      "type": "object",
      "properties": {

        "mobile": {
          "type": "integer"
        },
        "landLine": {
          "type": "integer"
        }
     }

    }
  }
}

您可以使用java.beans.Introspector.getBeanInfo(Class)。您可以在此处使用该机制的示例：Java Beans Introspector
