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
二、解决方案
1、pom.xml 增加依赖(2024.11.6 补充)
java
<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
java
@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
@Primary
public 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;
}
}
2、修改后运行测试
