@valid---用好valid，让接口干净

第一种JSR303

引入

<dependency>
        <groupId>org.hibernate.validator</groupId>
        <artifactId>hibernate-validator</artifactId>
      </dependency>

实体检查

one 1，2，3 逗号隔开的单个字符串

@NotEmpty(message = "channels can't null or empty")
    @Pattern(regexp = "(?:(\\d|[1-2]\\d|3[0-2])(?:,|$))+", message = "invalid channels")
    @ApiModelProperty(value = "设备通道，1开始.数字表示通道，0表示所有通道。用英文逗号间隔，此时的通道号操作都是对所有通道号一起操作", required = true)
    private String channels;

two 不能为null

@NotNull(message = "streamType can't null")

three 数字范围

@Range(min = 1, max = 32, message = “channels must be 1~32”)

@Range(min = 1, max = 32, message = "channels must be 1~32")
    @ApiModelProperty(value = "数字表示通道，设备通道，1开始", required = true)
    private Long channel;

four 日期

先配置yml

spring:
  jackson:
    default-property-inclusion: non_null
    date-format: yyyy-MM-dd HH:mm:ss
    time-zone: GMT+8
    deserialization:
      adjust_dates_to_context_time_zone: true

  @NotNull(message = "endTime can't be null")
//    @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    @ApiModelProperty(value = "结束时间, yyyy-MM-dd HH:mm:ss", required = true)
    private String endTime;

 @Pattern(regexp = "\\d{4}-\\d{2}", message = "`beginDate` must format be `yyyy-MM`")
    @ApiModelProperty(value = "查询的开始日期，格式 yyyy-MM", example = "2019-04")
    private String beginDate;
