一、依赖（我用的这一种亲测）

<!--LocalDate 去T-->
        <dependency>
            <groupId>cn.hutool</groupId>
            <artifactId>hutool-all</artifactId>
            <version>5.7.15</version>
        </dependency>

二、配置

@Configuration
public class LocalDateFormatConfig {

    /**
     * 格式化日期
     * @return Jackson2ObjectMapperBuilderCustomizer
     */
    @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))
                .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));
    }
}

三、扩展
springboot项目，可以使用注解@JsonFormat 也可以

 /**
     * 创建时间
     */
    @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")
    private LocalDateTime createTime;

其他方法

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.boot.autoconfigure.jackson.Jackson2ObjectMapperBuilderCustomizer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
 
import java.time.LocalDate;
import java.time.LocalDateTime;
import java.time.LocalTime;
import java.time.format.DateTimeFormatter;
@Configuration
public class LocalDateTimeSerializerConfig {
 @Bean(name = "mapperObject")
    public ObjectMapper getObjectMapper() {
        ObjectMapper om = new ObjectMapper();
        JavaTimeModule javaTimeModule = new JavaTimeModule();
        javaTimeModule.addSerializer(LocalDateTime.class, new LocalDateTimeSerializer(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss")));
        javaTimeModule.addSerializer(LocalDate.class, new LocalDateSerializer(DateTimeFormatter.ofPattern("yyyy-MM-dd")));
        javaTimeModule.addSerializer(LocalTime.class, new LocalTimeSerializer(DateTimeFormatter.ofPattern("HH:mm:ss")));
        om.registerModule(javaTimeModule);
        return om;
    }
    }
