springboot 介面引數型別為LocalDateTime解析失敗導致介面報錯 -解決

1.原因

springboot 框架不支援LocalDateTime的解析，需要自己新增一個解析配置

2.解決

建立一個配置類，位置隨意

import com.fasterxml.jackson.datatype.jsr310.deser.LocalDateTimeDeserializer;
import com.fasterxml.jackson.datatype.jsr310.ser.LocalDateTimeSerializer;
import org.springframework.boot.autoconfigure.jackson.Jackson2ObjectMapperBuilderCustomizer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;

@Configuration
public class LocalDateTimeConfig {
    /*
     * 序列化內容
     *   LocalDateTime -> String
     * 服務端返回給客戶端內容
     * */
    @Bean
    public LocalDateTimeSerializer localDateTimeSerializer() {
        return new LocalDateTimeSerializer(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"));
    }

    /*
     * 反序列化內容
     *   String -> LocalDateTime
     * 客戶端傳入服務端資料
     * */
    @Bean
    public LocalDateTimeDeserializer localDateTimeDeserializer() {
        return new LocalDateTimeDeserializer(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"));
    }


    // 配置
    @Bean
    public Jackson2ObjectMapperBuilderCustomizer jackson2ObjectMapperBuilderCustomizer() {
        return builder -> {
            builder.serializerByType(LocalDateTime.class, localDateTimeSerializer());
            builder.deserializerByType(LocalDateTime.class, localDateTimeDeserializer());
        };
    }
}
