咱們能夠找到org.springframework.security.web.firewall.StrictHttpFirewallweb

/**
 * <p>
 * Determines if semicolon is allowed in the URL (i.e. matrix variables). The default
 * is to disable this behavior because it is a common way of attempting to perform
 * <a href="https://www.owasp.org/index.php/Reflected_File_Download">Reflected File Download Attacks</a>.
 * It is also the source of many exploits which bypass URL based security.
 * </p>
 * <p>For example, the following CVEs are a subset of the issues related
 * to ambiguities in the Servlet Specification on how to treat semicolons that
 * led to CVEs:
 * </p>
 * <ul>
 *     <li><a href="https://pivotal.io/security/cve-2016-5007">cve-2016-5007</a></li>
 *     <li><a href="https://pivotal.io/security/cve-2016-9879">cve-2016-9879</a></li>
 *     <li><a href="https://pivotal.io/security/cve-2018-1199">cve-2018-1199</a></li>
 * </ul>
 *
 * <p>
 * If you are wanting to allow semicolons, please reconsider as it is a very common
 * source of security bypasses. A few common reasons users want semicolons and
 * alternatives are listed below:
 * </p>
 * <ul>
 * <li>Including the JSESSIONID in the path - You should not include session id (or
 * any sensitive information) in a URL as it can lead to leaking. Instead use Cookies.
 * </li>
 * <li>Matrix Variables - Users wanting to leverage Matrix Variables should consider
 * using HTTP parameters instead.
 * </li>
 * </ul>
 *
 * @param allowSemicolon should semicolons be allowed in the URL. Default is false
 */
public void setAllowSemicolon(boolean allowSemicolon) {
	if (allowSemicolon) {
		urlBlacklistsRemoveAll(FORBIDDEN_SEMICOLON);
	} else {
		urlBlacklistsAddAll(FORBIDDEN_SEMICOLON);
	}
}

這裏提到了，若是您想要分號，請從新考慮，由於它是安全繞過的一個很是常見的來源。下面列出了用戶須要分號和替代品的一些常見緣由：在路徑中包含JSESSIONID - 您不該在URL中包含會話ID（或任何敏感信息），由於它可能致使泄漏。而是使用Cookies。spring

解決方案

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

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