一、问题

MyBatis 返回 Map 或 List时，时间类型数据，默认为LocalDateTime
Springboot 响应给前端的LocalDateTime，默认含有’T’字符，如何统一配置去掉
在这里插入图片描述

二、解决方案

1、pom.xml 增加依赖（2024.11.6 补充）

		<dependency><groupId>com.fasterxml.jackson.datatype</groupId><artifactId>jackson-datatype-jsr310</artifactId><version>2.12.7</version></dependency>

2、创建配置类，对ObjectMapper对象进行定制，指定日期类对应的序列化与反序列化处理对象，如

@Configuration
public class LocalDateTimeFormatConfig {private static final String DEFAULT_DATE_TIME_PATTERN = "yyyy-MM-dd HH:mm:ss";private static final String DEFAULT_DATE_PATTERN = "yyyy-MM-dd";private static final String DEFAULT_TIME_PATTERN = "HH:mm:ss";@Bean@Primarypublic ObjectMapper objectMapper(){ObjectMapper objectMapper = new ObjectMapper();JavaTimeModule javaTimeModule = new JavaTimeModule();javaTimeModule.addSerializer(LocalDateTime.class, new LocalDateTimeSerializer(DateTimeFormatter.ofPattern(DEFAULT_DATE_TIME_PATTERN)));javaTimeModule.addSerializer(LocalDate.class, new LocalDateSerializer(DateTimeFormatter.ofPattern(DEFAULT_DATE_PATTERN)));javaTimeModule.addSerializer(LocalTime.class, new LocalTimeSerializer(DateTimeFormatter.ofPattern(DEFAULT_TIME_PATTERN)));javaTimeModule.addDeserializer(LocalDateTime.class, new LocalDateTimeDeserializer(DateTimeFormatter.ofPattern(DEFAULT_DATE_TIME_PATTERN)));javaTimeModule.addDeserializer(LocalDate.class, new LocalDateDeserializer(DateTimeFormatter.ofPattern(DEFAULT_DATE_PATTERN)));javaTimeModule.addDeserializer(LocalTime.class, new LocalTimeDeserializer(DateTimeFormatter.ofPattern(DEFAULT_TIME_PATTERN)));objectMapper.registerModule(javaTimeModule);return objectMapper;}
}
