@JsonProperty与@JSONField注解用处

public class User {
  @JsonProperty("JsonPropertyName")
  private String name;
  private String sex;
  private Integer age;
  //get/setter与tostring正常字段名：name、sex、age
}

@Test
public void testJsonProperty() throws IOException{
    User user=new User("shiyu","man",22);
    System.out.println(new ObjectMapper().writeValueAsString(user));
    String str="{\"sex\":\"man\",\"age\":22,\"JsonPropertyName\":\"shiyu\"}";
    System.out.println(new ObjectMapper().readValue(str,User.class).toString());
}
输出：
{"sex":"man","age":22,"JsonPropertyName":"shiyu"}
User [name=shiyu, sex=man, age=22]

public class User {
  @JSONField(name="JSONFieldName")
  private String name;
  private String sex;
  private Integer age;
  //get/setter与tostring正常字段名：name、sex、age
}

@Test
public void testSONField(){
    User user=new User("shiyu","man",22);
    System.out.println(JSON.toJSONString(user));
    String str="{\"JSONFieldName\":\"shiyu\",\"age\":22,\"sex\":\"man\"}";
    System.out.println(JSON.parseObject(str, User.class).toString()); 
}
输出
{"JSONFieldName":"shiyu","age":22,"sex":"man"}
User [name=shiyu, sex=man, age=22]
