如何在JSP页面中配置Spring Security以允许使用hasPermission？

您

CustomPermissionevaluator

尝试在SecurityConfig.java中遵循以下代码。

...import org.springframework.security.web.access.expression.DefaultWebSecurityexpressionHandler;...public class SecurityConfig extends WebSecurityConfigurerAdapter {  ...  @Override  public void configure(WebSecurity web) throws Exception {    DefaultWebSecurityexpressionHandler handler = new DefaultWebSecurityexpressionHandler();    handler.setPermissionevaluator(new CustomPermissionevaluator());    web.expressionHandler(handler);  }}

Web应用程序初始化器

...import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;...public class AnnotationConfigDispatcherServletInitializer extends    AbstractAnnotationConfigDispatcherServletInitializer {  @Override  protected Class<?>[] getRootConfigClasses() {    return new Class[] {      SecurityConfig.class,    };  }}
