【问题描述】：

我正在尝试将 Spring 应用程序迁移到 Spring Boot。在 tomcat 服务器上运行应用程序时出现以下错误：

请求被拒绝，因为 URL 未规范化。

我已尝试在我的入口点类中添加以下 bean 来解决错误。

    @Bean
    public InternalResourceViewResolver jspViewResolver() 
        InternalResourceViewResolver bean = new InternalResourceViewResolver();
        bean.setPrefix("/WEB-INF/ui/");
        bean.setSuffix(".jsp");
        return bean;
    

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

    @Bean
    public StrictHttpFirewall httpFirewall() 
        StrictHttpFirewall firewall = new StrictHttpFirewall();
        firewall.setAllowSemicolon(true);
        return firewall;
    

    @Bean
    public HttpFirewall defaultHttpFirewall() 
        return new DefaultHttpFirewall();
    

    public void configure(WebSecurity web) throws Exception 
        web.httpFirewall(allowUrlEncodedSlashHttpFirewall());
    

错误日志：

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

我希望我的 jsp 页面能够加载而不是抛出“Whitelabel 错误”。

【问题讨论】：

欺骗中的第二个答案将为您工作，并让您有时间解决前端发送的无效 URL，此时您应该删除解决方法以重新启用防火墙。但删除其他两个防火墙 bean。

【参考方案1】：

请检查客户端/浏览器发送的 URL 请求。

很可能网址之间的某处有双斜杠，例如http://localhost:8080/some//path/here

出于安全原因，Spring Boot 不允许这样做。

【讨论】：

不，网址没有任何双斜杠。

请分享正在形成的 url 以访问 api。 （无论是从客户那里形成的，还是您期望成为的）

但在本地部署之前 // 工作正常，为什么在部署之后会出现问题？
