LocalDateTime反序列化，LocalDateTime格式化

• 使用mybatis-plus的时候出现了LocalDateTime类（jdk8 中新出现的类
• 那么我在反序列化的时候出了问题。

我在springboot 2.1.3 中使用以下类结局问题）

• 用到了下面这个类解决了所有的问题。包括前端传值过来也能直接接受字符串
• 百度上面也猜了许许多多的坑 最终换了一个spring boot的版本 然后用以下的代码配置完美解决了问题

import com.fasterxml.jackson.databind.ObjectMapper;

import com.fasterxml.jackson.datatype.jsr310.JavaTimeModule;

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.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

import org.springframework.format.Formatter;

import java.text.ParseException;

import java.time.LocalDate;

import java.time.LocalDateTime;

import java.time.LocalTime;

import java.time.format.DateTimeFormatter;

import java.util.Locale;
