springboot启动报错（webSecurity匿名问题）

org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘springSecurityFilterChain’ defined in class path resource [org/springframework/security/config/annotation/web/configuration/WebSecurityConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.servlet.Filter]: Factory method ‘springSecurityFilterChain’ threw exception; nested exception is java.lang.IllegalStateException: An incomplete mapping was found for []. Try completing it with something like requestUrls()..hasRole(‘USER’)

在WebSecurityConfig(SecurityConfig)中配置

http.authorizeRequests()
                //放行swagger
                .antMatchers("/swagger-ui.html",
                        "/swagger-ui/*",
                        "/swagger-resources/**",
                        "/v2/**",
                        "/v3/**",
                        "/img.icons/**",
                        "/webjars/**",
                        "/doc.html").permitAll()
   				 //只有匿名用户才能访问，其他都要登录
                // 所有加 AnonymousAccess 注解的请求都允许匿名访问
                .antMatchers(getAnonymousUrls()).anonymous();
                //所有请求必须被认证（登录）
                .anyRequest().authenticated();
