java - 打开@GlobalMethodSecurity的Spring Boot异常

我试图在Spring Boot中启用@GlobalMethodSecurity以使用CustomPermissionEvaluator。
所以我要添加对应的MethodSecurityExpressionHandler bean并实现CustomPermissionEvaluator。请参阅下面的资源。

问题。
当我尝试在@EnableGlobalMethodSecurity中添加WebSecurityConfigurerAdapter时，出现以下错误：

Failed to instantiate [org.springframework.web.servlet.HandlerMapping]: Factory method 'resourceHandlerMapping' threw exception; nested exception is java.lang.IllegalStateException: No ServletContext set*.

我搜索了治愈方法，并找到了将MethodSecurityExpressionHandler移至另一个@Configuration类的建议。但是这是正确的决定吗？我认为这是一个错误，该错误已于2016年成功修复。

最佳答案

正如Rob Winch提议的那样，我将@EnableGlobalMethodSecurity移到了单独的配置，所以现在可以使用了。

@Configuration
@EnableGlobalMethodSecurity(securedEnabled = true, prePostEnabled = true)
public class CustomMethodSecurityConfig extends GlobalMethodSecurityConfiguration {

    @Autowired
    CustomPermissionEvaluator permissionEvaluator;

    @Bean
    public MethodSecurityExpressionHandler methodSecurityExpressionHandler() {
        DefaultMethodSecurityExpressionHandler handler = new DefaultMethodSecurityExpressionHandler();
        handler.setPermissionEvaluator(permissionEvaluator);
        return handler;
    }

}
