SpringBoot Controller 接收LocalDateTime

Controller 接收LocalDateTime 格式

配置Jackson 序列化和反序列化

import com.fasterxml.jackson.databind.ser.std.ToStringSerializer; import com.fasterxml.jackson.datatype.jsr310.deser.LocalDateDeserializer; import com.fasterxml.jackson.datatype.jsr310.deser.LocalDateTimeDeserializer; import com.fasterxml.jackson.datatype.jsr310.deser.LocalTimeDeserializer; import com.fasterxml.jackson.datatype.jsr310.ser.LocalDateSerializer; import com.fasterxml.jackson.datatype.jsr310.ser.LocalDateTimeSerializer; import com.fasterxml.jackson.datatype.jsr310.ser.LocalTimeSerializer; import org.springframework.boot.autoconfigure.jackson.Jackson2ObjectMapperBuilderCustomizer; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import java.time.LocalDate; import java.time.LocalDateTime; import java.time.LocalTime; import java.time.format.DateTimeFormatter; /** * 返回格式转换 */ @Configuration public class MvcSerializerConfig { /** * 默认日期时间格式 */ public static final String DEFAULT_DATE_TIME_FORMAT = "yyyy-MM-dd HH:mm:ss"; /** * 默认日期格式 */ public static final String DEFAULT_DATE_FORMAT = "yyyy-MM-dd"; /** * 默认时间格式 */ public static final String DEFAULT_TIME_FORMAT = "HH:mm:ss"; @Bean public LocalDateTimeSerializer localDateTimeSerializer() { return new LocalDateTimeSerializer(DateTimeFormatter.ofPattern(DEFAULT_DATE_TIME_FORMAT)); } @Bean public LocalDateTimeDeserializer localDateTimeDeserializer() { return new LocalDateTimeDeserializer(DateTimeFormatter.ofPattern(DEFAULT_DATE_TIME_FORMAT)); } @Bean public LocalDateSerializer localDateSerializer() { return new LocalDateSerializer(DateTimeFormatter.ofPattern(DEFAULT_DATE_FORMAT)); } @Bean public LocalDateDeserializer localDateDeserializer() { return new LocalDateDeserializer(DateTimeFormatter.ofPattern(DEFAULT_DATE_FORMAT)); } @Bean public LocalTimeSerializer localTimeSerializer() { return new LocalTimeSerializer(DateTimeFormatter.ofPattern(DEFAULT_TIME_FORMAT)); } @Bean public LocalTimeDeserializer localTimeDeserializer() { return new LocalTimeDeserializer(DateTimeFormatter.ofPattern(DEFAULT_TIME_FORMAT)); } @Bean public Jackson2ObjectMapperBuilderCustomizer jackson2ObjectMapperBuilderCustomizer() { return builder -> { builder // 返回 Long 会自定转换成 String .serializerByType(Long.class, ToStringSerializer.instance) .serializerByType(Long.TYPE, ToStringSerializer.instance) //时间类型的序列化与反序列化 用于返回时间格式与接收时间格式 .serializerByType(LocalDateTime.class, localDateTimeSerializer()) .deserializerByType(LocalDateTime.class, localDateTimeDeserializer()) .serializerByType(LocalDate.class, localDateSerializer()) .deserializerByType(LocalDate.class, localDateDeserializer()) .serializerByType(LocalTime.class, localTimeSerializer()) .deserializerByType(LocalTime.class, localTimeDeserializer()) ; }; } }

初始化绑定 配合服用
