由于时间格式可能多种多样，为了防止出现不常见的时间格式，我们进行全局处理：

package com.llpp.config;

import com.fasterxml.jackson.datatype.jsr310.ser.LocalDateSerializer;
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.core.convert.converter.Converter;

import java.time.LocalDate;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;

@Configuration
public class DateConverterConfig {
    private static final String DATETIMEFORMAT = "yyyy-MM-dd HH:mm:ss"; // 日期时间格式
    private static final String DATEFORMAT = "yyyy-MM-dd"; // 日期格式

    // 项目全局的时间出参格式化
    @Bean
    public Jackson2ObjectMapperBuilderCustomizer jackson2ObjectMapperBuilderCustomizer() {
        return builder -> {
            builder.simpleDateFormat(DATEFORMAT);
            builder.simpleDateFormat(DATETIMEFORMAT);
            builder.serializers(new LocalDateSerializer(DateTimeFormatter.ofPattern(DATEFORMAT)));
            builder.serializers(new LocalDateTimeSerializer(DateTimeFormatter.ofPattern(DATETIMEFORMAT)));
        };
    }

    // 自定义时间转换器
    @Bean
    public Converter<String, LocalDate> localDateConverter() {
        return new Converter<String, LocalDate>() {
            @Override
            public LocalDate convert(String source) {
                // 使用指定格式解析字符串为LocalDate
                return LocalDate.parse(source, DateTimeFormatter.ofPattern(DATEFORMAT));
            }
        };
    }

    // 自定义时间转换器
    @Bean
    public Converter<String, LocalDateTime> localDateTimeConverter() {
        return new Converter<String, LocalDateTime>() {
            @Override
            public LocalDateTime convert(String source) {
                // 使用指定格式解析字符串为LocalDateTime
                return LocalDateTime.parse(source, DateTimeFormatter.ofPattern(DATETIMEFORMAT));
            }
        };
    }
}
