SpringSecurity 遭遇JSP页面读取不出的情况，EL表达式失效

 

org.apache.jasper.JasperException: An exception occurred processing JSP page
 

<jsp:forward page="/pages/main.jsp"></jsp:forward>



javax.servlet.ServletException: javax.servlet.jsp.JspException: java.io.IOException: No visible WebSecurityExpressionHandler instance could be found in the application context. There must be at least one in order to support expressions in JSP 'authorize' tags.

 

 

在SpringSecurity配置页面，为了不使用SPEL表达式，把JTEL表达式也给禁用了

 <security:http auto-config="true" use-expressions="false">

 

为了使JSP页面不出错，在配置文件中配置一个

<bean id="webexpressionHandler" class="org.springframework.security.web.access.expression.DefaultWebSecurityExpressionHandler" />
