我使用spring security 3.1.7.RELEASE with spring 3.2.13.RELEASE。
我在spring-security.xml中输入如下内容:
<http auto-config="true" use-expressions="true">
<intercept-url pattern=".*admin.htm" access="hasRole(ROLE_ADMIN)" />
<intercept-url pattern="/siteadmin/*.htm" access="ROLE_ADMIN" />
<intercept-url pattern="/siteadmin/cleancache.htm" access="hasRole('ROLE_ADMIN')" />
当我尝试点击url /siteadmin/cleancache.htm时,我得到以下异常:
java.lang.IllegalArgumentException:无法计算表达式 &#39; ROLE_ADMIN&#39; org.springframework.security.access.expression.ExpressionUtils.evaluateAsBoolean(ExpressionUtils.java:13) org.springframework.security.web.access.expression.WebExpressionVoter.vote(WebExpressionVoter.java:34) org.springframework.security.web.access.expression.WebExpressionVoter.vote(WebExpressionVoter.java:18) org.springframework.security.access.vote.AffirmativeBased.decide(AffirmativeBased.java:62)
根本原因:
org.springframework.expression.spel.SpelEvaluationException: EL1008E:(pos 0):属性或字段&#39; ROLE_ADMIN&#39;无法找到 对象类型 &#39; org.springframework.security.web.access.expression.WebSecurityExpressionRoot&#39; - 也许不公开? org.springframework.expression.spel.ast.PropertyOrFieldReference.readProperty(PropertyOrFieldReference.java:214) org.springframework.expression.spel.ast.PropertyOrFieldReference.getValueInternal(PropertyOrFieldReference.java:85) org.springframework.expression.spel.ast.PropertyOrFieldReference.getValueInternal(PropertyOrFieldReference.java:78) org.springframework.expression.spel.ast.SpelNodeImpl.getTypedValue(SpelNodeImpl.java:102) org.springframework.expression.spel.standard.SpelExpression.getValue(SpelExpression.java:98) org.springframework.security.access.expression.ExpressionUtils.evaluateAsBoolean(ExpressionUtils.java:11) org.springframework.security.web.access.expression.WebExpressionVoter.vote(WebExpressionVoter.java:34)
高度赞赏任何关于它的指针。

你有一些错别字。第一个intercept-url行缺少ROLE_ADMIN周围的单引号,第二行缺少hasRole。它应该是
<http auto-config="true" use-expressions="true">
<intercept-url pattern=".*admin.htm" access="hasRole('ROLE_ADMIN')" />
<intercept-url pattern="/siteadmin/*.htm" access="hasRole('ROLE_ADMIN')" />
<intercept-url pattern="/siteadmin/cleancache.htm" access="hasRole('ROLE_ADMIN')" />

安全弹簧的官方文档会带来您放置的示例:
<Intercept-url pattern = "/ siteadmin / *. Htm" access = "ROLE_ADMIN" />
但你应该穿上
<Intercept-url pattern = ". * Admin.htm" access = "hasRole ('ROLE_ADMIN')" />
