本文介绍如何通过Maven引入依赖并配置全局类来实现Java中LocalDateTime类型的自定义序列化，去除默认的'T'字符。

  //实体类----对应数据库的字段属性datetime
   @TableField("recordTime")
    private LocalDateTime recordTime;

1、maven引入jar

        <dependency>
            <groupId>com.fasterxml.jackson.datatype</groupId>
            <artifactId>jackson-datatype-jsr310</artifactId>
            <version>2.9.8</version>
        </dependency>

2、创建一个全局配置类

package com.yimning.smartclass.config;
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 {

    @Bean
    public LocalDateTimeSerializer localDateTimeDeserializer() {
        return new LocalDateTimeSerializer(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"));
    }

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