sharp-common集成验证Service验证

对Service中的方法的参数进行校验，该如何做呢？

Spring validator 方法级别的校验

只需要加入类注解 @Validated

@Service
@Validated
public class UserService {

    public void save(@Valid User user,
                     @Min(value = 22, message = "不能小于22岁") Integer age) {
        System.out.println("userService save...");
    }

    public void save2(@NotBlank String title) {
        System.out.println("userService save3...");
    }
}

spring 在此基础上进行了扩展，添加了 MethodValidationPostProcessor 拦截器，可以实现对方法参数的校验。

    <artifactId>spring-boot-starter-aop</artifactId>
</dependency>

@Configuration
@RequiredArgsConstructor
@Import({ServiceMethodValidationInterceptor.class})
public class AppConfig {
    private final Validator validator;
    @Bean
    public ValidatorHelper validatorHelper() {
        return new ValidatorHelper(validator);
    }
}

@Service
public class UserService {

    @Validated
    public void save(@Valid User user,
                     @Min(value = 22, message = "不能小于22岁") Integer age) {
        System.out.println("userService save...");
    }

    @Validated
    public void save2(@NotBlank String title) {
        System.out.println("userService save3...");
    }
}

扫描service目录下，类名是Service结尾的类。只要在方法上加注解 @Validated
