postman提交json格式时间，不能反序列化为LocalDateTime?
postman提交的时间参数
"beginTime":"2022-12-26T9:40:00","endTime":"2022-12-30T23:40:00"

实体类
@TableField(exist = false) private LocalDateTime beginTime;
private LocalDateTime endTime;
回答：
@TableField(exist = false)@DateTimeFormat(pattern = "yyyy-MM-dd")
private LocalDateTime beginTime;
@DateTimeFormat(pattern = "yyyy-MM-dd")
private LocalDateTime endTime;
回答：
以SpringBoot为例
引入JSR-310的相关依赖
<dependency><groupId>com.fasterxml.jackson.datatype</groupId>
<artifactId>jackson-datatype-jsr310</artifactId>
</dependency>
增加配置
spring.jackson.serialization.write-dates-as-timestamps=false- 这样应该就可以正确序列化LoacalDateTime了
- 扩展：如果需要支持更多种的日期格式（非标准的），需要重新定义Jackson的ObjectMapper，并加入JSR310的相关序列化规则
public static final String DEFAULT_DATETIME_MS_PATTERN = "yyyy-MM-dd HH:mm:ss.SSS"; public static final String DEFAULT_DATETIME_PATTERN = "yyyy-MM-dd HH:mm:ss";
public static final String DEFAULT_DATE_PATTERN = "yyyy-MM-dd";
public static final String DEFAULT_TIME_PATTERN = "HH:mm:ss";
public static final String ABSOLUTE_DATETIME_MS_PATTERN = "yyyyMMddHHmmssSSS";
public static final String ABSOLUTE_DATETIME_PATTERN = "yyyyMMddHHmmss";
public static final String ABSOLUTE_DATE_PATTERN = "yyyyMMdd";
public static final String ABSOLUTE_TIME_PATTERN = "HHmmss";
public static final String DATE_TIME_LENGTH_26 = "yyyy-MM-dd+HH:mm:ss.SSSSSS";
static ObjectMapper configureObjectMapper(ObjectMapper objectMapper) {
// Set Naming Strategy
objectMapper.setPropertyNamingStrategy(PropertyNamingStrategy.LOWER_CAMEL_CASE);
// Set Feature
objectMapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);
objectMapper.disable(SerializationFeature.FAIL_ON_EMPTY_BEANS);
objectMapper.disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES);
objectMapper.enable(MapperFeature.PROPAGATE_TRANSIENT_MARKER);
objectMapper.enable(JsonReadFeature.ALLOW_BACKSLASH_ESCAPING_ANY_CHARACTER.mappedFeature());
objectMapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);
// Handle Java Time & JSR310
registerJavaTime(objectMapper);
return objectMapper;
}
/**
* registerJavaTime
*
* <p>Handle Time Format to JSR310
*
* @author Created by ivan at 下午2:52 2020/1/10.
*/
public static void registerJavaTime(ObjectMapper objectMapper) {
// Handle Java Time
objectMapper.registerModule(new JavaTimeModule());
// Handle JSR310 Time
SimpleModule jsr310Module = new SimpleModule();
jsr310Module.addSerializer(
LocalDateTime.class,
new LocalDateTimeSerializer(
DateTimeFormatter.ofPattern(DateTimePatterns.DEFAULT_DATETIME_PATTERN)));
jsr310Module.addSerializer(
LocalDate.class,
new LocalDateSerializer(
DateTimeFormatter.ofPattern(DateTimePatterns.DEFAULT_DATE_PATTERN)));
jsr310Module.addSerializer(
LocalTime.class,
new LocalTimeSerializer(
DateTimeFormatter.ofPattern(DateTimePatterns.DEFAULT_TIME_PATTERN)));
jsr310Module.addDeserializer(
LocalDateTime.class,
new LocalDateTimeDeserializer(
DateTimeFormatter.ofPattern(DateTimePatterns.DEFAULT_DATETIME_PATTERN)));
jsr310Module.addDeserializer(
LocalDate.class,
new LocalDateDeserializer(
DateTimeFormatter.ofPattern(DateTimePatterns.DEFAULT_DATE_PATTERN)));
jsr310Module.addDeserializer(
LocalTime.class,
new LocalTimeDeserializer(
DateTimeFormatter.ofPattern(DateTimePatterns.DEFAULT_TIME_PATTERN)));
objectMapper.registerModule(jsr310Module);
}
- 最后通过配置Spring的HttpMessageConverters，替换掉原有的Jackson ObjectMapper。这样新的请求会根据配置的规则，进行格式判断，并进行转换。
以上是 postman提交json格式时间，不能反序列化为LocalDateTime? 的全部内容， 来源链接： utcz.com/p/944901.html
