5.1、验证手机号是否有效示例

5.1.1、定义验证注解类

import static java.lang.annotation.ElementType.ANNOTATION_TYPE;
import static java.lang.annotation.ElementType.CONSTRUCTOR;
import static java.lang.annotation.ElementType.FIELD;
import static java.lang.annotation.ElementType.METHOD;
import static java.lang.annotation.ElementType.PARAMETER;
import static java.lang.annotation.ElementType.TYPE_USE;
import static java.lang.annotation.RetentionPolicy.RUNTIME;

import java.lang.annotation.Documented;
import java.lang.annotation.Retention;
import java.lang.annotation.Target;

import javax.validation.Constraint;
import javax.validation.Payload;

@Target({ METHOD, FIELD, ANNOTATION_TYPE, CONSTRUCTOR, PARAMETER, TYPE_USE })
@Retention(RUNTIME)
@Documented
@Constraint(validatedBy = { MobileValidator.class })
public @interface IsMobile {

    boolean required() default true;

    String message() default "手机号码格式错误";

    Class<?>[] groups() default {};

    Class<? extends Payload>[] payload() default {};

}

5.1.2、定义验证核心类

import static org.springframework.util.StringUtils.hasText;

import java.util.regex.Pattern;

public class MobileValidator implements javax.validation.ConstraintValidator<IsMobile, String> {

    private static final Pattern mobile_pattern = Pattern.compile("[1]([3-9])[0-9]{9}$");
    private boolean              required       = false;

    @Override
    public boolean isValid(String value, javax.validation.ConstraintValidatorContext context) {
        if (required) {
            return isMobile(value);
        } else {
            if (!hasText(value)) {
                return true;
            } else {
                return isMobile(value);
            }
        }
    }

    @Override
    public void initialize(IsMobile constraintAnnotation) {
        required = constraintAnnotation.required();
    }

    private boolean isMobile(String mobile) {
        if (!hasText(mobile)) {
            return false;
        }

        return mobile_pattern.matcher(mobile).matches();
    }
}

5.1.3、验证异常统一处理

import java.util.HashMap;
import java.util.Map;

import org.springframework.web.bind.MethodArgumentNotValidException;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.RestControllerAdvice;

@RestControllerAdvice
public class GlobalExceptionHandler {

    @ExceptionHandler(MethodArgumentNotValidException.class)
    public Map<String, Object> handleMethodArgumentNotValidException(MethodArgumentNotValidException e) {
        return new HashMap<String, Object>(2) {

            private static final long serialVersionUID = 6073161079995491657L;

            {
                put("code", 500);
                put("msg", e.getBindingResult().getFieldError().getDefaultMessage());
            }

        };
    }

}

5.1.4、控制器引入验证

import java.util.Collections;
import java.util.HashMap;
import java.util.Map;
import java.util.UUID;

import javax.validation.constraints.NotBlank;

import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;

import com.cnblogs.javalouvre.controller.validator.IsMobile;

@RestController
public class IndexController {

    @PostMapping(path = "/")
    public Map<String, Object> execute(@Validated @RequestBody User user) {
        return new HashMap<String, Object>(3) {

            private static final long serialVersionUID = 6073161079995491657L;

            {
                put("code", 1);
                put("msg", "OK");
                put("data", Collections.singletonMap("num", UUID.randomUUID().toString().replace("-", "")));
            }

        };
    }
}

class User {

    @NotBlank(message = "手机号不可为空")
    @IsMobile
    private String mobile;

    public String getMobile() {
        return mobile;
    }

    public void setMobile(String mobile) {
        this.mobile = mobile;
    }

}

5.1.5、启动服务验证

5.1.5.1、验证正确

$ curl -L -X POST 'http://127.0.0.1:8080' \
> -H 'Content-Type: application/json' \
> --data-raw '{
>     "mobile": "13800138000"
> }'
{"msg":"OK","data":{"num":"94694a9e567241999bd4259aca7b7e7a"},"code":1}

5.1.5.2、验证失败

$ curl -L -X POST 'http://127.0.0.1:8080' -H 'Content-Type: application/json' --data-raw '{
    "mobile": "03800138000"
}'
{"msg":"手机号码格式错误","code":500}

6、Calling REST Services

7、Web Services
