如何从动态生成pojo类中获取属性

Question

我正在使用jsonschema2pojo-maven-plugin v0.4.7从JSON模式生成POJO类。在那里我想获取动态生成的pojo类的属性。pojo类包含onather pojo类。是否有解决方案来阅读包含onather的pojo类的字段？例如在这种情况下，我有Employee pojo，因为有Address对象我想要获取这两个类的字段。

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)。这里有一个示例使用该机制：Java Beans Introspector
