输入表单验证

1.添加依赖

           <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-validation</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>

2.创建实体类，以下面举例

@Data
public class AddressBookDto {


    //用户id
    @NotNull
    @Min(2222)
    private Long userId;


    //收货人 或 雇员名称
    @NotNull
    @Size(min = 2, max = 30)
    private String consignee;


    //手机号
    private String phone;


    //性别 0 女 1 男
    private String sex;


    //省级区划编号
    private String provinceCode;


    //省级名称
    private String provinceName;


    //市级区划编号
    private String cityCode;


    //市级名称
    private String cityName;


    //区级区划编号
    private String districtCode;


    //区级名称
    private String districtName;


    //详细地址
    private String detail;


    //标签 比如 公司、家
    private String label;

    //是否默认 0 否 1是
    private Integer isDefault;


    //是否删除

    private Integer isDeleted;
}

3.在controller代码里面加入BindingResult bindingResult，在要验证的实体中前加@Valid

    @PostMapping("/save")
    public Result<AddressBook> save(@Parameter(description = "addressBookDto")
                                        @RequestBody @Valid AddressBookDto addressBookDto, BindingResult bindingResult) {
        AddressBook addressBook = new AddressBook();
        BeanUtils.copyProperties(addressBookDto, addressBook);
        return Result.success(addressBookService.save(addressBook));
    }

4.在AOP中加入以下代码

@Aspect
@Component
public class WebLogAspect {

    @Autowired
    ObjectMapper objectMapper;
    Logger logger = LoggerFactory.getLogger(WebLogAspect.class);

    @Around("execution(* com.integration.scaffold.relationaldataaccess.mysql.controller.*.*(..))")
    public Object doBasicProfiling(ProceedingJoinPoint pjp) throws Throwable {
        // 记录调用的方法和参数
        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = attributes.getRequest();
        Long startTime = System.currentTimeMillis();
        logger.info("请求ip是：{}", request.getRemoteAddr());
        logger.info("请求url是: {}", request.getRequestURL().toString());
        logger.info("请求方法是: {}", request.getMethod());
        logger.info("处理Method:{},请求方法：{}", pjp.getSignature().getDeclaringTypeName(), pjp.getSignature().getName());
        logger.info("请求参数是：{}", pjp.getArgs());
        for (Object obj : pjp.getArgs()) {
            if (obj instanceof BindingResult) {
                BindingResult bindingResult = (BindingResult) obj;
                if (bindingResult.hasErrors()) {
                    List<ObjectError> errors = bindingResult.getAllErrors();
                    StringBuffer sb = new StringBuffer();
                    for (ObjectError objectError : errors) {
                        sb.append(Arrays.stream(objectError.getArguments()).findFirst() + "---" +
                                objectError.getCode() + "---" + objectError.getDefaultMessage());
                    }
                    logger.info("返回结果是：{}", Result.fail(sb.toString()));
                    Long endTime = System.currentTimeMillis();
                    logger.info("执行方法耗时:{}秒", (endTime - startTime) / 1000.0);
                    return Result.fail(sb.toString());

                }
            }
        }
        Object retVal = pjp.proceed();
        // stop stopwatch
        logger.info("返回结果是：{}", objectMapper.writeValueAsString(retVal));
        Long endTime = System.currentTimeMillis();
        logger.info("执行方法耗时:{}秒", (endTime - startTime) / 1000.0);
        return retVal;
    }
}

启动项目，进行测试

当不符合条件时：

当符合条件时：

点击比如@Min所在的包里面有很多的验证条件，都是可以使用的哦
