key 命名策略
UpperCamelCaseStrategy
首字母大写的驼峰方式，@JsonProperty优先级更高（msgHint没有受UpperCamelCaseStrategy影响）
    "CodeInfo": 0,
    "Data":
        "Nickname": "nickname",
        "IdCard": "idcard"
    "msgHint": "success"
LowerCamelCaseStrategy
首字母小写的驼峰方式
    "codeInfo": 0,
    "data":
        "nickname": "nickname",
        "idCard": "idcard"
    "msgHint": "success"
UpperSnakeCaseStrategy
大写及下划线拼接
    "CODE_INFO": 0,
    "DATA":
        "NICKNAME": "nickname",
        "ID_CARD": "idcard"
    "msgHint": "success"
SnakeCaseStrategy
小写及下划线拼接
    "code_info": 0,
    "data":
        "nickname": "nickname",
        "id_card": "idcard"
    "msgHint": "success"
LowerCaseStrategy
    "codeinfo": 0,
    "data":
        "nickname": "nickname",
        "idcard": "idcard"
    "msgHint": "success"
KebabCaseStrategy
中划线拼接
    "code-info": 0,
    "data":
        "nickname": "nickname",
        "id-card": "idcard"
    "msgHint": "success"
LowerDotCaseStrategy
小写及.拼接
    "code.info": 0,
    "data":
        "nickname": "nickname",
        "id.card": "idcard"
    "msgHint": "success"
YAML 配置
spring:
  jackson:
    property-naming-strategy: com.fasterxml.jackson.databind.PropertyNamingStrategies.UpperCamelCaseStrategy
#    property-naming-strategy: com.fasterxml.jackson.databind.PropertyNamingStrategies.LowerCamelCaseStrategy
#    property-naming-strategy: com.fasterxml.jackson.databind.PropertyNamingStrategies.UpperSnakeCaseStrategy
#    property-naming-strategy: com.fasterxml.jackson.databind.PropertyNamingStrategies.SnakeCaseStrategy
#    property-naming-strategy: com.fasterxml.jackson.databind.PropertyNamingStrategies.LowerCaseStrategy
#    property-naming-strategy: com.fasterxml.jackson.databind.PropertyNamingStrategies.KebabCaseStrategy
#    property-naming-strategy: com.fasterxml.jackson.databind.PropertyNamingStrategies.LowerDotCaseStrategy
Java 配置
@Configuration
public class ObjectMapperConfig {
    @Bean
    public ObjectMapper objectMapper() {
        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setPropertyNamingStrategy(PropertyNamingStrategies.UpperCamelCaseStrategy.INSTANCE);
        return objectMapper;
使用@JsonNaming注解指定命名策略。
@Setter
@Getter
@Data
@JsonNaming(PropertyNamingStrategies.UpperCamelCaseStrategy.class)
public class Response {
    private int codeInfo;
    private Object data;
    @JsonProperty("msgHint")
    private String msgHint = "success";
PropertyNamingStrategy不适用于Map集合。
