JSON Gson的LocalDateTime和String转化

package com.bitsun.bizcenter.ic.api.config;

import com.google.gson.*;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import java.time.LocalDate;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;

@Configuration
public class GSONConfiguration {

    //序列化
    final static JsonSerializer<LocalDateTime> jsonSerializerDateTime = (localDateTime, type, jsonSerializationContext) -> new JsonPrimitive(localDateTime.format(DateTimeFormatter.ISO_LOCAL_DATE_TIME));
    final static JsonSerializer<LocalDate> jsonSerializerDate = (localDate, type, jsonSerializationContext) -> new JsonPrimitive(localDate.format(DateTimeFormatter.ISO_LOCAL_DATE));
    //反序列化
    final static JsonDeserializer<LocalDateTime> jsonDeserializerDateTime = (jsonElement, type, jsonDeserializationContext) -> LocalDateTime.parse(jsonElement.getAsJsonPrimitive().getAsString(), DateTimeFormatter.ISO_LOCAL_DATE_TIME);
    final static JsonDeserializer<LocalDate> jsonDeserializerDate = (jsonElement, type, jsonDeserializationContext) -> LocalDate.parse(jsonElement.getAsJsonPrimitive().getAsString(), DateTimeFormatter.ISO_LOCAL_DATE);

    @Bean
    public Gson create() {
        return new GsonBuilder()
                .setPrettyPrinting()
                /* 更改先后顺序没有影响 */
                .registerTypeAdapter(LocalDateTime.class, jsonSerializerDateTime)
                .registerTypeAdapter(LocalDate.class, jsonSerializerDate)
                .registerTypeAdapter(LocalDateTime.class, jsonDeserializerDateTime)
                .registerTypeAdapter(LocalDate.class, jsonDeserializerDate)
                .create();
    }
}
If you’re going to reuse code, you need to understand that code!
