为什么Spring Boot拒绝GET请求，因为URL没有规范化？[重复]

Question

我正在尝试将一个spring应用程序迁移到spring-boot。在tomcat服务器上运行应用程序时，我收到以下错误：

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 来解决该错误。

    @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页面加载，而不是抛出“白标错误”。

Answer 1

请检查客户端/浏览器发送的 URL 请求。

最有可能的是，url中间有双斜杠。http://localhost:8080/some//path/here

由于安全原因，Spring开机不允许这样做。
