Unsatisfied dependency expressed through method 'traceFilterRegist

完整错误

Unsatisfied dependency expressed through method 'traceFilterRegistration' parameter 0; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'javax.servlet.Filter' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Qualifier(value="webRequestLoggingFilter")}

先说下背景，这个错误时在eurekaserver中排除了spring-boot-start-actuator的依赖产生

修复方式

1.     @Bean
2.     Filter webRequestLoggingFilter() {
3.         return new Filter() {
4.             @Override
5.             public void init(FilterConfig filterConfig) throws ServletException {
7.             }
9.             @Override
10.             public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
11.                 filterChain.doFilter(servletRequest, servletResponse);
12.             }
14.             @Override
15.             public void destroy() {
17.             }
18.         };
19.     }
