* 自定义参数校验器
* <p>
* 愿景：实现自动生成验证失败的消息
* 1、字段名根据{@link ApiModelProperty#value()}注解获取
* 2、状态根据{@link NotNull}、{@link javax.validation.constraints.NotEmpty}等生成
* 3、拼接返回消息
* <p>
* 如果实现后则以后只需要加{@code @NotNull @NotEmpty}注解，不需要再一个个写{@link NotNull#message()}的值
* <p>
* 2021.4.15 此次实现是类似于多数据源的实现，通过{@link ValidatorProxy}代理
* 默认校验类({@link org.hibernate.validator.internal.engine.ValidatorImpl})和自定义校验类(this)
* · 该类只处理参数校验{@link this#validateParameters(Object, Method, Object[], Class[])}
* · 其他校验都交给默认实现
* · 因此这个类只实现了参数校验的方法

* 参数校验实现
* <p>
* 功能说明：https://blog.csdn.net/qq_38688267/article/details/115720412
* <p>
* 环境搭建：
* 1、实现{@link cn.iocoder.dashboard.framework.validator.custom.handler.ValidateAnnotationHandler}
* 2、将实现类注册到{@link cn.iocoder.dashboard.framework.validator.custom.handler.ValidateHandlerHelper}中
* 3、实现全局异常拦截{@link javax.validation.ConstraintViolationException}异常
*
* 使用步骤：
* 1、给存在需要校验方法的Controller加上{@link javax.validation.Validator} 注解
* 2、给需要校验的方法的参数加上 {@link javax.validation.Valid} 注解
* 3、给需要校验的参数属性加上想要校验的注解，
* 如{@link javax.validation.constraints.NotNull} {@link javax.validation.constraints.NotEmpty}等
* <p>
* DEMO:
* {@link cn.iocoder.dashboard.modules.system.controller.auth.SysAuthController#login(cn.iocoder.dashboard.modules.system.controller.auth.vo.auth.SysAuthLoginReqVO)}
* <p>
* 亮点：
* 校验过程中有实现对集合类型对象的递归校验，实现深层校验
