java无法计算表达式“hasRole（用户）”的值

Question

我想使用spring security 5.3

在xml上进行如下配置

<http auto-config="true">
    <intercept-url pattern="/list" access="hasRole(USER)"/>
    <intercept-url pattern="/security" access="isAnonymous()"/>
    <http-basic />
    <form-login login-page="/security"
                  login-processing-url="/security"
                  default-target-url="/list"
                  authentication-failure-url="/security?error"
                  username-parameter="username"
                  password-parameter="password"/>

    <logout logout-success-url="/security?logout"/>
    <csrf disabled="true"/>
</http>

<authentication-manager>
    <authentication-provider>
        <user-service>
            <user name="user" password="$2a$10$BHjEcnhAgqRH0Vj6aPmGTOtQfYdx3PsvTWjsVxVBouiLTzGSLTSz2" authorities="USER"/>
        </user-service>
        <password-encoder ref="encoder" />
    </authentication-provider>
</authentication-manager>

<beans:bean id="encoder" class="org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder"/>

当我登录时，出现以下错误：

java.lang.IllegalArgumentException: Failed to evaluate expression 'hasRole(USER)' org.springframework.security.access.expression.ExpressionUtils.evaluateAsBoolean(ExpressionUtils.java:30) org.springframework.security.web.access.expression.WebExpressionVoter.vote(WebExpressionVoter.java:52) org.springframework.security.web.access.expression.WebExpressionVoter.vote(WebExpressionVoter.java:33) org.springframework.security.access.vote.AffirmativeBased.decide(AffirmativeBased.java:63) org.springframework.security.access.intercept.AbstractSecurityInterceptor.beforeInvocation(AbstractSecurityInterceptor.java:233) org.springframework.security.web.access.intercept.FilterSecurityInterceptor.invoke(FilterSecurityInterceptor.java:123) org.springframework.security.web.access.intercept.FilterSecurityInterceptor.doFilter(FilterSecurityInterceptor.java:90) org.springframework.security.web.FilterChainProxy$VirtualFilterChain.doFilter(FilterChainProxy.java:334) org.springframework.security.web.access.ExceptionTranslationFilter.doFilter(ExceptionTranslationFilter.java:118) org.springframework.security.web.FilterChainProxy$VirtualFilterChain.doFilter(FilterChainProxy.java:334) org.springframework.security.web.session.SessionManagementFilter.doFilter(SessionManagementFilter.java:137) org.springframework.security.web.FilterChainProxy$VirtualFilterChain.doFilter(FilterChainProxy.java:334) org.springframework.security.web.authentication.AnonymousAuthenticationFilter.doFilter(AnonymousAuthenticationFilter.java:111) org.springframework.security.web.FilterChainProxy$VirtualFilterChain.doFilter(FilterChainProxy.java:334) org.springframework.security.web.servletapi.SecurityContextHolderAwareRequestFilter.doFilter(SecurityContextHolderAwareRequestFilter.java:158) org.springframework.security.web.FilterChainProxy$VirtualFilterChain.doFilter(FilterChainProxy.java:334) org.springframework.security.web.savedrequest.RequestCacheAwareFilter.doFilter(RequestCacheAwareFilter.java:63) org.springframework.security.web.FilterChainProxy$VirtualFilterChain.doFilter(FilterChainProxy.java:334) org.springframework.security.web.authentication.www.BasicAuthenticationFilter.doFilterInternal(BasicAuthenticationFilter.java:155) org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:119) org.springframework.security.web.FilterChainProxy$VirtualFilterChain.doFilter(FilterChainProxy.java:334) org.springframework.security.web.authentication.AbstractAuthenticationProcessingFilter.doFilter(AbstractAuthenticationProcessingFilter.java:200) org.springframework.security.web.FilterChainProxy$VirtualFilterChain.doFilter(FilterChainProxy.java:334) org.springframework.security.web.authentication.logout.LogoutFilter.doFilter(LogoutFilter.java:116) org.springframework.security.web.FilterChainProxy$VirtualFilterChain.doFilter(FilterChainProxy.java:334) org.springframework.security.web.header.HeaderWriterFilter.doHeadersAfter(HeaderWriterFilter.java:92) org.springframework.security.web.header.HeaderWriterFilter.doFilterInternal(HeaderWriterFilter.java:77) org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:119) org.springframework.security.web.FilterChainProxy$VirtualFilterChain.doFilter(FilterChainProxy.java:334) org.springframework.security.web.context.request.async.WebAsyncManagerIntegrationFilter.doFilterInternal(WebAsyncManagerIntegrationFilter.java:56) org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:119) org.springframework.security.web.FilterChainProxy$VirtualFilterChain.doFilter(FilterChainProxy.java:334) org.springframework.security.web.context.SecurityContextPersistenceFilter.doFilter(SecurityContextPersistenceFilter.java:105) org.springframework.security.web.FilterChainProxy$VirtualFilterChain.doFilter(FilterChainProxy.java:334) org.springframework.security.web.FilterChainProxy.doFilterInternal(FilterChainProxy.java:215) org.springframework.security.web.FilterChainProxy.doFilter(FilterChainProxy.java:178) org.springframework.web.filter.DelegatingFilterProxy.invokeDelegate(DelegatingFilterProxy.java:358) org.springframework.web.filter.DelegatingFilterProxy.doFilter(DelegatingFilterProxy.java:271)

我的代码中有什么错误

Answer 1

org.springframework.expression.spel.SpelEvaluationException: EL1008E: Property or field 'USER' cannot be found on object of type

从上面的错误可以看出，问题在于spring安全框架无法识别用户。您忘记将用户添加到“”中

问题在于表达式：<intercept-url pattern="/list" access="hasRole(USER)"/>。 用<intercept-url pattern="/list" access="hasRole('USER')"/>替换它，它就会工作

我看到的另一个问题是，您正在使用hasRole来保护/list资源，但您已将权限授予用户authorities="USER"。将要发生的是，hasRole将把前缀ROLE_uu添加到您传入的用户参数中。所以ROLE_USER不等于USER，这是您分配给用户的权限

要解决此问题，您可以将权限更改为“`authorities=“ROLE\u USER”`”

或者你可以用hasAuthority代替hasRole，如下所示： access="hasAuthority('USER')"

Answer 2

我用hasAuthority('USER')替换了hasRole(USER)，效果很好

Answer 3

应该是的

hasRole('USER')

注意：单引号围绕用户
