需要在maven中添加依賴:

        <!--LocalDateTime-->
        <dependency>
            <groupId>com.fasterxml.jackson.datatype</groupId>
            <artifactId>jackson-datatype-jsr310</artifactId>
            <version>2.9.2</version>
        </dependency>
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis-typehandlers-jsr310</artifactId>
            <version>1.0.2</version>
        </dependency>

添加配置文件

??springboot或spring自定義jackson的MapperObject對象淋叶，spring也可以通過xml配置的方式加入jackson配置慨默。

@Configuration
public class JacksonConfig {
    @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")));
        javaTimeModule.addDeserializer(LocalDateTime.class, new LocalDateTimeDeserializer(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss")));
        javaTimeModule.addDeserializer(LocalDate.class, new LocalDateDeserializer(DateTimeFormatter.ofPattern("yyyy-MM-dd")));
        javaTimeModule.addDeserializer(LocalTime.class, new LocalTimeDeserializer(DateTimeFormatter.ofPattern("HH:mm:ss")));
        om.registerModule(javaTimeModule);
        return om;
    }
}

??SpringMVC使用@RequestBody钠至、@ResponseBody、@RestController注解時劲件，會使用自定義的MapperObject對象進(jìn)行json到LocalDate锣枝、LocalTime唇撬、LocalDateTime對象轉(zhuǎn)換墩弯。

??Mybatis通過通過mybatis-typehandlers-jsr310來把LocalDate省骂、LocalTime、LocalDateTime映射到數(shù)據(jù)庫的date最住、timestamp、datetime等字段怠惶。

??如果SpringMVC接受的不是json參數(shù)涨缚，則要使用@DateTimeFormat(iso = DateTimeFormat.ISO.DATE_TIME)注解來轉(zhuǎn)換LocalDateTime

    @PostMapping("/test1")
    public void test1(@RequestParam @DateTimeFormat(iso = DateTimeFormat.ISO.DATE_TIME) LocalDateTime localDateTime ) {
    }
    @PostMapping("/test2")
    public void test2(@RequestParam @DateTimeFormat(iso = "dd.MM.yyyy") LocalDate localDate ) {
    }
