使用Liferay进行Tomcat 8启动时存在严重的安全约束 [英] Severe security constraints while tomcat 8 startup with liferay

问题描述

tomcat 8带有liferay时，我收到以下严重消息.

I am getting the below severe message while the tomcat 8 comes up with liferay.

SEVERE [localhost-startStop-1] org.apache.tomcat.util.descriptor.web.SecurityConstraint.findUncoveredHttpMethods For security constraints with URL pattern [/bg/c/portal/protected] only the HTTP methods [POST GET] are covered. All other methods are uncovered.

这对服务器启动没有任何影响，但不确定是什么原因导致的?任何帮助将不胜感激.

推荐答案

这意味着在web.xml中，有人仅针对模式/bg/c/portal/protected上的POST和GET方法指定了安全约束，可能与此类似:

It means that in web.xml someone has specified a security constraint just for methods POST and GET on pattern /bg/c/portal/protected, possibly in a similar way to this:

<security-constraint>
    <web-resource-collection>
        <url-pattern>/bg/c/portal/protected</url-pattern>
        <http-method>POST</http-method>
        <http-method>GET</http-method>
    </web-resource-collection>
    <user-data-constraint>
        <transport-guarantee>...</transport-guarantee>
    </user-data-constraint>
</security-constraint>

您应该删除http-method括号以使其与该url-pattern的所有方法匹配，或者如果您想为其设置不同的安全性约束而没有任何http-method括号，则创建第二个方法.

You should either remove http-method brackets so it will match all methods for this url-pattern or create second one if you would like to set different security constraints on it without any http-method brackets.

例如，如果您想使用SSL /bg/c/portal/protected端点保护POST和GET方法的安全，但是对于其他不需要的端点，则应创建如下配置:

For instance if you would like to secure with SSL /bg/c/portal/protected endpoint for the POST and GET methods, but for others you do not need that then you should create a config like this:

<security-constraint>
    <web-resource-collection>
        <url-pattern>/bg/c/portal/protected</url-pattern>
        <http-method>POST</http-method>
        <http-method>GET</http-method>
    </web-resource-collection>
    <user-data-constraint>
        <transport-guarantee>CONFIDENTIAL</transport-guarantee>
    </user-data-constraint>
</security-constraint>
<security-constraint>
    <web-resource-collection>
        <url-pattern>/bg/c/portal/protected</url-pattern>
    </web-resource-collection>
    <user-data-constraint>
        <transport-guarantee>NONE</transport-guarantee>
    </user-data-constraint>
</security-constraint>

如您所见，此模式的所有方法均已涵盖，因此不会引发任何错误.

As you see now all methods for this pattern are covered, hence no error will be thrown.
