SpringBoot整合`ng-alain`时报错如下：

> **org.springframework.security.web.firewall.RequestRejectedException: The request was rejected because the URL was not normalized.**

查看源码`spring`中`StrictHttpFirewall.java`中报错源码如下：  
![在这里插入图片描述][20181127164745445.png]

判断逻辑在`isNormalized(request)`函数中，如果请求路径中包含双斜杠`//`，则会抛出这样的错误。

查看我们的请求，请求中确实包含如下路径：

参照 [https://stackoverflow.com/questions/48453980/spring-5-0-3-requestrejectedexception-the-request-was-rejected-because-the-url/49116274][https_stackoverflow.com_questions_48453980_spring-5-0-3-requestrejectedexception-the-request-was-rejected-because-the-url_49116274] 解决方案，通过自定义`Firewall`的方式允许URL中出现斜杠`slash`

@Bean
    public HttpFirewall allowUrlEncodedSlashHttpFirewall() {
        StrictHttpFirewall firewall = new StrictHttpFirewall();
        firewall.setAllowUrlEncodedSlash(true);    
        return firewall;
    }

添加之后，正常访问
