记一次SpringBoot Filter的过滤器被重复执行问题

记一次SpringBoot Filter的过滤器被重复执行问题

debug发现过滤器 执行两次，后来定位到WebFilter和Component注解导致多次扫描，而这次需要用到WebFilter，所以注掉了Component

@Order(0)
//@Component
@WebFilter(urlPatterns = {"/*"})
@ConditionalOnProperty(name = "color.trace.start", havingValue = "true")
public class ThreadFilter implements Filter {
    public ThreadFilter() {
        System.out.println("color.trace.start...");
    }

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {

    }

    @Override
    public void doFilter(ServletRequest servletRequest, ServletResponse
            servletResponse, FilterChain filterChain) throws IOException, ServletException {
        String requestId = StrUtils.genRequestId();
        ThreadLocalUtils.init(requestId);
        MDC.put(MDC_TRACE_ID,requestId);
        filterChain.doFilter(servletRequest, servletResponse);
        ThreadLocalUtils.close();
    }

    @Override
    public void destroy() {

    }
}

@EnableColorProxy
@ServletComponentScan("com.player3.color.filter")
@SpringBootApplication
public class EshopOrderApplication {

    public static void main(String[] args) {
        SpringApplication.run(EshopOrderApplication.class, args);
    }

}
