问题现象
解决办法如下
1、使用@JsonFormat
@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")
结果
2、使用SpringMVC提供的ExtendMessageConverters
@Slf4j
@Configuration
public class WebMvcConfig extends WebMvcConfigurationSupport {
/**
* 扩展消息转换器
*/
@Override
protected void extendMessageConverters(List<HttpMessageConverter<?>> converters) {
log.info("扩展消息转换器~~~");
// 创建一个消息转换器
MappingJackson2HttpMessageConverter httpMessageConverter = new MappingJackson2HttpMessageConverter(new JacksonObjectMapper());
// 存入SpringMVC容器
converters.add(0, httpMessageConverter);
}
}
public class JacksonObjectMapper extends ObjectMapper {
public static final String DEFAULT_DATE_FORMAT = "yyyy-MM-dd";
public static final String DEFAULT_DATE_TIME_FORMAT = "yyyy-MM-dd HH:mm:ss";
// public static final String DEFAULT_DATE_TIME_FORMAT = "yyyy-MM-dd HH:mm";
public static final String DEFAULT_TIME_FORMAT = "HH:mm:ss";
public JacksonObjectMapper() {
super();
// 收到未知属性时不报异常
this.configure(FAIL_ON_UNKNOWN_PROPERTIES, false);
// 反序列化时,属性不存在的兼容处理
this.getDeserializationConfig().withoutFeatures(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES);
SimpleModule simpleModule = new SimpleModule()
.addDeserializer(LocalDateTime.class, new LocalDateTimeDeserializer(DateTimeFormatter.ofPattern(DEFAULT_DATE_TIME_FORMAT)))
.addDeserializer(LocalDate.class, new LocalDateDeserializer(DateTimeFormatter.ofPattern(DEFAULT_DATE_FORMAT)))
.addDeserializer(LocalTime.class, new LocalTimeDeserializer(DateTimeFormatter.ofPattern(DEFAULT_TIME_FORMAT)))
.addSerializer(LocalDateTime.class, new LocalDateTimeSerializer(DateTimeFormatter.ofPattern(DEFAULT_DATE_TIME_FORMAT)))
.addSerializer(LocalDate.class, new LocalDateSerializer(DateTimeFormatter.ofPattern(DEFAULT_DATE_FORMAT)))
.addSerializer(LocalTime.class, new LocalTimeSerializer(DateTimeFormatter.ofPattern(DEFAULT_TIME_FORMAT)));
// 添加自定义序列化器和反序列化器
this.registerModule(simpleModule);
}
}
