[英]Rest Web Service - Object Mapper
I am working on Rest based application where I am creating the rest client. 我正在基于Rest的应用程序中创建我的Rest客户端。 The problem is while sending the post request the object is expected to be JSON.
问题是在发送发布请求时,该对象应为JSON。
Class User{ String first_Name; String last_Name; //getters & setters }
ObjectWriter ow = new ObjectMapper().writer().withDefaultPrettyPrinter(); String json = ow.writeValueAsString(object);
The above code returns with correct JSON format, however the underscore of the class attributes are getting eliminated. 上面的代码以正确的JSON格式返回,但是消除了类属性的下划线。 Eg.
例如。 I am expected the result to be like
我希望结果像
{"first_Name":"Joseph","last_Name":"Thomas"}
but the actual result is 但实际结果是
{"firstName":"Joseph","lastName":"Thomas"}.
Can someone help me how to get the json with underscore. 有人可以帮助我如何使用下划线获取json。 Appreciate your help on this.
感谢您的帮助。
You should use @JsonProperty()
in your User class: Example: 您应该在User类中使用
@JsonProperty()
:示例:
@JsonProperty("first_Name")
String first_Name;
@JsonProperty("last_Name")
String first_Name;
Annotate your fields with @JsonProperty
, eg 用
@JsonProperty
注释您的字段,例如
@JsonProperty("first_Name")
private String firstName;
