http basic的春季安全配置问题：IllegalArgument

Question

我似乎无法弄清楚为什么此配置提供了IllegalArgumentException。 错误是：

Caused by: java.lang.IllegalArgumentException: A universal match pattern ('/**') is defined  before other patterns in the filter chain, causing them to be ignored. Please check the ordering in your <security:http> namespace or FilterChainProxy bean configuration

配置为：

    <!-- Disable Spring Security for static content -->
<http pattern="/css/**" security="none"/>
<http pattern="/js/**" security="none"/>

<!-- Web app security -->
<http use-expressions="true" authentication-manager-ref="pvDatabase">   
    <!-- Insecure endpoints -->
    <intercept-url pattern="/" access="permitAll"/>
    <intercept-url pattern="/spring/login" access="permitAll"/>
    <intercept-url pattern="/spring/loginfail" access="permitAll"/>
    <intercept-url pattern="/spring/loggedout" access="permitAll"/>     
    <intercept-url pattern="/insecure/**" access="permitAll"/>

    <!-- Secure endpoints -->               
    <intercept-url pattern="/secure/admin/**" access="hasAnyRole('ADMIN')"/>
    <intercept-url pattern="/spring/**" access="hasAnyRole('ADMIN', 'USER')"/>
    <intercept-url pattern="/secure/**" access="hasAnyRole('ADMIN', 'USER')"/>      

    <!-- Authentication Entrypoint is FORM-LOGIN -->
    <form-login login-page="/spring/login" 
        login-processing-url="/spring/login"
        authentication-failure-url="/spring/loginfail" 
        default-target-url="/spring/loginsuccess" 
        always-use-default-target="true" />
    <logout logout-url="/spring/logout" logout-success-url="/spring/loggedout" delete-cookies="JSESSIONID" invalidate-session="true"/>
    <csrf/>

    <!-- HTTP 403 Access denied custom handling -->
    <access-denied-handler ref="pvAccessDeniedHandler"/>
</http>

<!-- Web services security : this section generates an error -->
<http use-expressions="true" create-session="stateless" authentication-manager-ref="pvDatabase">
    <!-- Authentication Entrypoint is HTTP-BASIC -->
    <http-basic entry-point-ref="PVBasicAuthenticationEntryPoint"/>

    <!-- secure endpoints : web services -->
    <intercept-url pattern="/services/api/**" access="hasAnyRole('ADMIN', 'WEBSERVICES')"/>

    <!-- HTTP 403 Access denied custom handling -->
    <access-denied-handler ref="pvAccessDeniedHandler"/>
</http>

如果删除整个Web服务安全性部分，则安全性很好，我想要的是能够使用basic-auth 仅保护/ services / api / **模式，并将其限制为仅具有ADMIN和WEBSERVICES角色的用户。

我不确定我是否理解错误，因为没有定义其他通用匹配的url模式，我没有在任何地方映射/ **。

我的应用程序包含2个Dispatcher servlet，第一个映射到/ spring / *，第二个映射到/ services / api / *。 Spring Security筛选器链映射到/ *

Answer 1

此错误是因为还按顺序考虑了http块，并且http块的默认模式是/ **。 如果除了最后一个http块之外的所有块都没有pattern属性，则永远不会看到其他块。

将模式添加到第一个http块应该可以解决您的问题。 如果pattern不起作用，则还可以将RequestMatcher的自定义实例与request-matcher-ref一起使用 。
