springboot接收日期类型参数

如果使用Get请求，直接使用对象接收，则可以使用@DateTimeFormat注解进行格式化，如：

@DateTimeFormat(pattern = "yyyy-MM-dd")
private Date startBuyDate;

如果使用Post请求，@RequestBody接收请求体参数，默认解析日期格式为yyyy-MM-dd HH:mm:ss , 如果需要接收其他格式的参数，则可以使用@JsonFormat注解，如：

@JsonFormat(timezone="GMT+8",pattern="yyyy-MM-dd")
private Date buyDate;

也可以使用java8新增的LocalDate自定义序列化，如：

@Configuration
@ConditionalOnClass(ObjectMapper.class)
@AutoConfigureBefore(JacksonAutoConfiguration.class)
public class JacksonConfig {
    @Bean
    public Jackson2ObjectMapperBuilderCustomizer customizer() {
        return builder -> {
            builder.locale(Locale.CHINA);
            builder.timeZone(TimeZone.getTimeZone(ZoneId.systemDefault()));
            builder.simpleDateFormat(DatePattern.NORM_DATETIME_PATTERN);
            builder.modules(new TimeModule());
        };
    }
}

public class TimeModule extends SimpleModule {

    public TimeModule() {
        super(PackageVersion.VERSION);
        this.addSerializer(LocalDateTime.class, new LocalDateTimeSerializer(DateTimeFormatter.ofPattern(DatePattern.NORM_DATETIME_PATTERN)));
        this.addSerializer(LocalDate.class, new LocalDateSerializer(DateTimeFormatter.ofPattern(DatePattern.NORM_DATE_PATTERN)));
        this.addSerializer(LocalTime.class, new LocalTimeSerializer(DateTimeFormatter.ofPattern(DatePattern.NORM_TIME_PATTERN)));
        this.addDeserializer(LocalDateTime.class, new LocalDateTimeDeserializer(DateTimeFormatter.ofPattern(DatePattern.NORM_DATETIME_PATTERN)));
        this.addDeserializer(LocalDate.class, new LocalDateDeserializer(DateTimeFormatter.ofPattern(DatePattern.NORM_DATE_PATTERN)));
        this.addDeserializer(LocalTime.class, new LocalTimeDeserializer(DateTimeFormatter.ofPattern(DatePattern.NORM_TIME_PATTERN)));
    }
}

//yyyy-MM-dd HH:mm:ss
private LocalDateTime buyDateTime;

//yyyy-MM-dd
private LocalDate buyDate;

//HH:mm:ss
private LocalTime buyTime;
