在我们前一遍博客中有谈到springboot基于validation写出简介优雅的restful接口  
[springboot基于validation写出简介优雅的restful接口][springboot_validation_restful]  
当我们把这个真正加到生产的项目中时发现下面这个奇怪的提示。

这里我们将一步一步分析，是怎么找到这个错误原因的，并且解决掉他

org.springframework.web.bind.MethodArgumentNotValidException: Validation failed for argument [2] in public com.sike.okya.common.base.Response<java.util.List<com.sike.okya.common.responseDto.IntuitiveLikeQueryRes>> com.sike.okya.web.manage.controller.intuitive.IntuitiveLikeNodeController.queryIntuitiveLike(javax.servlet.http.HttpServletRequest,javax.servlet.http.HttpServletResponse,com.sike.okya.common.requestDto.intuitiva.QueryIntuitiveLikeNodeReq) throws java.lang.Exception: [Field error in object 'queryIntuitiveLikeNodeReq' on field 'lessonUnique': rejected value []; codes [NotBlank.queryIntuitiveLikeNodeReq.lessonUnique,NotBlank.lessonUnique,NotBlank.java.lang.String,NotBlank]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [queryIntuitiveLikeNodeReq.lessonUnique,lessonUnique]; arguments []; default message [lessonUnique]]; default message [lessonUnique 课时id不能为空]]

看到这个提示错误，一开始以为是这个错误

/**
     * 跨域处理过滤器
     */
    @Component
    @WebFilter(urlPatterns = {  "/*" }, filterName = "crosFilter")
    public class CrosFilter implements Filter { 
        final Logger logger = LoggerFactory.getLogger(this.getClass());
    
        @Override
        public void init(FilterConfig filterConfig) throws ServletException { 
        }
    
        @Override
        public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException { 
            HttpServletRequest request = (HttpServletRequest) servletRequest;
            HttpServletResponse response = (HttpServletResponse) servletResponse;
            String origin = request.getHeader("origin");// 获取源站
            response.setHeader("Access-Control-Allow-Origin", origin);
            response.setHeader("Access-Control-Allow-Methods", "POST, GET, PUT, OPTIONS");
            response.setHeader("Access-Control-Max-Age", "3600");
            response.setHeader("Access-Control-Allow-Credentials", "true");
            response.setHeader("Access-Control-Allow-Headers", "Content-Type, Access-Control-Allow-Headers, Authorization, X-Requested-With");
            filterChain.doFilter(servletRequest, servletResponse);
        }
    
        @Override
        public void destroy() { 
        }
    }

发现是跨域的，经过调试，发现和这个然并软。问题并不在这里，好我们继续下一步，在想是不是没有进入到我们这个拦截器呢？ 于是我们在这个方法上加上exceptionHandler上加上抛异常的注解，  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl8zMDQwOTkyNw_size_16_color_FFFFFF_t_70 1]  
好，下面我们试试效果，发现如下图所示，我们发现有点眉目了，说明我们方向是正确的。  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl8zMDQwOTkyNw_size_16_color_FFFFFF_t_70 2]  
那出现这个的原因是什么呢？ 我们大致分析下应该是spring 容器里面没有获取到该bean  
这个原因大概是：

*  1.确保注解@RestControllerAdvice/@ControllerAdvice的类被spring容器管理到。
    
    ①spring boot Java配置检查@SpringBootApplication(scanBasePackages = )（scanBasePackages 配置的包是否包含这个类默认情况下spring boot项目扫描的是@SpringBootApplication注解所在类的包及子包）  
    ② xml配置的spring 普通项目检查<context:component-scan base-package=“com.test”/>

1.  2.检查项目中所有的切面编程，是否在某个切面将异常try-catch然后没有扔出来。常见的就是切面的环绕处理，捕获了异常忘记抛出来。
2.  3.检查项目中是否有其他的相同的全局异常处理类，例如BaseController中是否已经定义了

最后一遍一遍的检查我们发现原来该项目里面存在一个RestControllerAdvice

看项目结构我们发现此加载在我们之前，所以最终原因我们找到了，原来是没有加载到spring容器里面。

再次测试我们发现又可以愉快的敲代码了
