Spring Boot LocalDateTime格式处理（返回前台显示）

2019独角兽企业重金招聘Python工程师标准>>>

1、maven引入jar

    com.fasterxml.jackson.datatype
    jackson-datatype-jsr310
    2.9.8

2、Bean增加注解

/**
     * 创建时间
     */
    @JsonFormat(shape=JsonFormat.Shape.STRING, pattern="yyyy-MM-dd HH:mm:ss")
    @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    private LocalDateTime createDate;

经验证以下配置不是必须添加项目

spring boot 注解：@Configuration增加以下

@Bean(name = "mapperObject")
public ObjectMapper getObjectMapper() {
    ObjectMapper om = new ObjectMapper();
    JavaTimeModule javaTimeModule = new JavaTimeModule();
    javaTimeModule.addSerializer(LocalDateTime.class, new LocalDateTimeSerializer(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss")));
    javaTimeModule.addSerializer(LocalDate.class, new LocalDateSerializer(DateTimeFormatter.ofPattern("yyyy-MM-dd")));
    javaTimeModule.addSerializer(LocalTime.class, new LocalTimeSerializer(DateTimeFormatter.ofPattern("HH:mm:ss")));
    om.registerModule(javaTimeModule);
    return om;

或者

@Bean(name = "OBJECT_MAPPER_BEAN")
public ObjectMapper jsonObjectMapper() {
    return Jackson2ObjectMapperBuilder.json()
            .serializationInclusion(JsonInclude.Include.NON_NULL) // Don’t include null values
            .featuresToDisable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS) //ISODate
            .modules(new JSR310Module())
            .build();
}

其它参考

另外增加SpringBoot与fastjson与Jackson切换方案
