java接口数据校验

validation 实现java接口校验

-1.所需依赖

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-validation</artifactId>
  <version>2.2.2.RELEASE</version>
  <scope>compile</scope>
  <exclusions>
    <exclusion>
      <artifactId>tomcat-embed-el</artifactId>
      <groupId>org.apache.tomcat.embed</groupId>
    </exclusion>
  </exclusions>
</dependency>

• 2.controller测试代码

@RequestMapping("/test3")
    public String addBatch(@RequestBody @Valid CtResultDto data, BindingResult result) {
        if (result.hasErrors()) {
            StringBuffer errorStr = new StringBuffer();
            List<FieldError> fieldErrors = result.getFieldErrors();
            fieldErrors.forEach(error -> {
                errorStr.append(error.getField()).append("->").append(error.getDefaultMessage()).append(";");
            return errorStr.toString();
        }
        return "success";
    }

• 实体类测试代码

//实体1
@Data
public class CtResultDto extends HosCtResultVo {
    @Valid
    public List<HosCtTubercleInfoPO> ctTubercleInfoPOList;
    @Valid
    public HosPersonInfoPO hosPersonInfoPO;
    @NotNull(message = "CT业务表id不能为空")
    private Integer ctRecordStatusId;   //CT业务表id
    @NotNull
    @Min(value = 1,message = "录入状态必须大于1")
    @Max(value = 2,message = "录入状态必须小于2")
    private Integer inputStatus;   //录入状态 1 提交 3保存草稿
    private Integer checkInfoId;
}
//实体2
@Data
public class HosCtResultVo implements Serializable {
    @NotNull(message="机构id不能为空")
    @Min(0)
    @Max(Integer.MAX_VALUE)
    private Integer deptId;
    @NotNull(message="检查日期不能为空")
    private Date examinationDate;
    @Pattern(regexp = "^1[3|4|5|7|8][0-9]{9}$", message = "用户手机号不合法")
    private String phone;
}
//实体3
@Data
public class HosPersonInfoPO implements Serializable {
    @NotNull(message = "HosPersonInfoPO.id不能为null")
    @Min(value = 10,message = "HosPersonInfoPO.id最小值为10")
    private Integer id;
}
//实体4
@Data
public class HosCtTubercleInfoPO implements Serializable {
    @NotNull(message = "HosCtTubercleInfoPO.id 不能为null")
    private Integer id;
}

• 入参

{"type":1,"hosPersonInfoPO":{"id":1},"ctTubercleInfoPOList":[{}]}

• 校验结果

examinationDate->检查日期不能为空;deptId->机构id不能为空;hosPersonInfoPO.id->HosPersonInfoPO.id最小值为10;ctRecordStatusId->CT业务表id不能为空;inputStatus->不能为null;ctTubercleInfoPOList[0].id->HosCtTubercleInfoPO.id 不能为null;

注意：@NotEmpty只能用作String类型的校验；@Size用作校验List类型的size
