面对不遵守驼峰命名规则的接口咋办?当然首先要吐槽一下,不过接口是别人定的,虽然看着不爽但还是得去适配,比如cardNumber,他返回的叫{CARDNUMBER:''}。
通过对API的研究可以通过@JsonProperty以及@JsonAutoDetect来实现。
先看代码
@JsonAutoDetect(JsonMethod.FIELD) public class MemberApiParameter implements Serializable { private static final long serialVersionUID = 1L; /** 姓名 **/ @JsonProperty("NAME") private String name; /** 性别 **/ @JsonProperty("SEX") private String sex; public String getName() { return name; } public void setName(String name) { this.name = name; } public String getSex() { return sex; } public void setSex(String sex) { this.sex = sex; } }
@JsonProperty("NAME")顾名思义,就是显示指定字段的别名,不管是输入还是输出都是这个名字。
@JsonAutoDetect(JsonMethod.FIELD)这个的意思是指解析字段,如果不这样设置,有兴趣的朋友可以试一下,会输出两套东西,类似{name:'',NAME:''},也就是说字段和getter方法都解析了,所以需要制定只解析字段名,忽略方法。还有一种方法就是需要一行行的在所有getter上加上@JsonIgnore,如果字段多就累死了。
JsonMethod的API说明:
Enum Constant Summary ALL This pseudo-type indicates that all of real types are included |
CREATOR Creators are constructors and (static) factory methods used to construct POJO instances for deserialization |
FIELD Field refers to fields of regular Java objects. |
GETTER Getters are methods used to get a POJO field value for serialization, or, under certain conditions also for de-serialization. |
IS_GETTER "Is getters" are getter-like methods that are named "isXxx" (instead of "getXxx" for getters) and return boolean value (either primitive, or Boolean ). |
NONE This pseudo-type indicates that none of real types is included |
SETTER Setters are methods used to set a POJO value for deserialization. |
