想在SpringBoot中添加一个自定义的filter 发现sevlet3支持 @WebFilter 于是添加之如下

@Configure
@WebFilter(
        urlPatterns = "/admin/*",
        filterName = "AdminFilter",
)
public class ManageFilter implements Filter {
    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
        System.out.println("init manage filter ....");
    }

    @Override
    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {

        filterChain.doFilter(servletRequest,servletResponse);
    }

    @Override
    public void destroy() {

    }
}

启动时已初始化此filter 但是urlpatterns 怎么也对不上
o.s.b.w.servlet.FilterRegistrationBean : Mapping filter: 'manageFilter' to: [/*]

百思不得其解,试了好几种方法都不work. 一直以为是urlpattern的问题

google后去掉@Configure 在Application添加 @ServletComponentScan 解决问题

@ImportResource("classpath:applicationContext.xml")
@ServletComponentScan
@SpringBootApplication
public class SpringBootAnnotatedApp {
 
    public static void main(String[] args) {
        SpringApplication.run(SpringBootAnnotatedApp.class, args);
    }
}
