一、日期格式化配置DateFormatConfig
@Configuration
public class DateFormatConfig {
@Bean
@Primary
public ObjectMapper serializingObjectMapper() {
ObjectMapper objectMapper = new ObjectMapper();
JavaTimeModule javaTimeModule = new JavaTimeModule();
javaTimeModule.addSerializer(LocalDateTime.class, new LocalDateTimeSerializer());
javaTimeModule.addDeserializer(LocalDateTime.class, new LocalDateTimeDeserializer());
objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
objectMapper.setTimeZone(TimeZone.getDefault());
objectMapper.setDateFormat(new SimpleDateFormat(DateFormatUtil.PATTERN_DEFAULT_ON_SECOND));
objectMapper.registerModule(javaTimeModule);
SimpleModule simpleModule = new SimpleModule();
simpleModule.addSerializer(BigInteger.class, ToStringSerializer.instance);
simpleModule.addSerializer(Long.class, ToStringSerializer.instance);
simpleModule.addSerializer(Long.TYPE, ToStringSerializer.instance);
simpleModule.addSerializer(Date.class, new DateSerializer());
simpleModule.addDeserializer(Date.class, new DateDeserializer());
objectMapper.registerModule(simpleModule);
return objectMapper;
}
/**

* @description Date 时间类型装换
*/
@Component
public class DateSerializer extends JsonSerializer<Date> {
@Override
public void serialize(Date date, JsonGenerator gen, SerializerProvider provider) throws IOException, IOException {
try {
String formattedDate = DateUtils.parseDateToStr(DateUtils.YYYY_MM_DD_HH_MM_SS, date);
String dateStr = DateUtils.parseDateToStr(DateUtils.YYYY_MM_DD_HH_MM_SS, DateFormatUtil.pareDate(formattedDate));
gen.writeString(dateStr);
} catch (ParseException e) {
e.printStackTrace();
throw new RuntimeException(e);
}
}
}
/**

*/
@Component
public class DateDeserializer extends JsonDeserializer<Date> {
@Override
public Date deserialize(JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException {
try {
String param = jsonParser.getValueAsString();
Date date = DateFormatUtil.pareDate(param);
return date;
} catch (ParseException e) {
e.printStackTrace();
throw new RuntimeException(e);
}
}
}
/**

* @description LocalDate 时间类型装换
*/
public class LocalDateTimeSerializer extends JsonSerializer<LocalDateTime> {
@Override
public void serialize(LocalDateTime value, JsonGenerator gen, SerializerProvider serializers) throws IOException {
Date ldate = Date.from(value.atZone(ZoneId.systemDefault()).toInstant());
Date date = null;
try {
date = DateFormatUtil.pareDate(DateUtils.parseDateToStr(DateUtils.YYYY_MM_DD_HH_MM_SS, ldate));

}
}
}
/**

*/
public class LocalDateTimeDeserializer extends JsonDeserializer<LocalDateTime> {
@Override
public LocalDateTime deserialize(JsonParser p, DeserializationContext deserializationContext) throws IOException {
try {
String param = p.getValueAsString();
Date date = DateFormatUtil.pareDate(param);
String str = DateUtils.parseDateToStr(DateUtils.YYYY_MM_DD_HH_MM_SS,date);
LocalDateTime dateTime = LocalDateTime.parse(str, DateTimeFormatter.ofPattern(DateUtils.YYYY_MM_DD_HH_MM_SS));
return dateTime;
} catch (ParseException e) {
e.printStackTrace();
throw new RuntimeException(e);
}
}
}
}
二、建立日期格式化工具DateFormatUtil
