返回时间LocalDateTime带有T的解决办法

1、第一种解决办法：在字段上加上注解

@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss") 如下图：

2、第一种方法每个字段都必须添加这个注解，可以使用第二种方法，如下：

先引入糊涂工具包，本人项目中使用版本：hutoll-all.version = 

5.7.15

    cn.hutool
    hutool-all
    ${hutool-all.version}

创建日期格式化配置类：

import cn.hutool.core.date.DatePattern;
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 org.springframework.context.annotation.Primary;

import java.time.LocalDate;
import java.time.LocalDateTime;
import java.time.LocalTime;


@Configuration
public class LocalDateFormatConfig {

    
    @Bean
    @Primary
    public Jackson2ObjectMapperBuilderCustomizer jackson2ObjectMapperBuilderCustomizer(){
//日期转字符串
        return builder -> builder.serializerByType(LocalDate.class,new LocalDateTimeSerializer(DatePattern.NORM_DATE_FORMATTER))
                .serializerByType(LocalDateTime.class,new LocalDateTimeSerializer(DatePattern.NORM_DATETIME_FORMATTER))
                .serializerByType(LocalTime.class,new LocalDateTimeSerializer(DatePattern.NORM_TIME_FORMATTER))
//字符串转日期
.deserializerByType(LocalDateTime.class,new LocalDateTimeDeserializer(DatePattern.NORM_DATETIME_FORMATTER))
.deserializerByType(LocalDate.class,new LocalDateDeserializer(DatePattern.NORM_DATE_FORMATTER))
.deserializerByType(LocalTime.class,new LocalTimeDeserializer(DatePattern.NORM_TIME_FORMATTER));
    }
}
