目的：都是为了解决json字符串的某些属性名和JavaBean中的属性名匹配不上的问题。
- JsonProperty
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]- JSONField
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]
