SpringBoot项目@WebFilter过滤器urlPatterns配置失效的解决方案,以及多个filter过滤器demo
作者:互联网
版本说明: spring-boot-starter-parent 2.1.11.RELEASE
1:定义两个filter过滤器类
public class MyFilter1 implements Filter { @Override public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { // todo XXX chain.doFilter(request, response); } @Override public void init(FilterConfig filterConfig) throws ServletException { } @Override public void destroy() { } }
再定义第二个过滤器 MyFilter2,代码同上。 注意:不添加任何注解!
2:filter注册为一个bean
在SpringBoot启动类里添加@Configuration 注解,这可以让SpringBoot认得@Bean注解。然后启动类里添加如下代码:
@Bean MyFilter1 getApiAuthenticationFilter1(){ return new MyFilter1(); } @Bean("myFilter1RegistrationBeanName") public FilterRegistrationBean<MyFilter1> registerFilter1(MyFilter1 myFilter1) { FilterRegistrationBean<MyFilter1> registrationBean = new FilterRegistrationBean(); registrationBean.setFilter(myFilter1); registrationBean.addUrlPatterns("/account/*"); //url拦截 registrationBean.setOrder(1); registrationBean.setAsyncSupported(true); return registrationBean; } @Bean //这里特意注册为一个bean,是可以让spring容器在filter类里注入@Autowited字段 MyFilter2 getInnerApiAuthFilter1(){ return new MyFilter2(); } @Bean("myFilter2RegistrationBeanName") //注意,如果是多个filter,一定要给bean命名不通的名字 public FilterRegistrationBean<MyFilter2> registerFilter2(MyFilter2 myFilter2) { //传参方式而非new对象的方式,可以从spring容器里得到bean对象 FilterRegistrationBean<MyFilter2> registrationBean = new FilterRegistrationBean(); registrationBean.setFilter(myFilter2); registrationBean.addUrlPatterns("/api/*"); registrationBean.setOrder(2); registrationBean.setAsyncSupported(true); return registrationBean; }
3:修改log日志打印级别为debug
在application.properties配置文件中,添加日志级别配置:logging.level.org.springframework.boot=debug
4:日志打印验证url拦截
2020-01-02 19:35:19.125 DEBUG 61918 [main] o.s.b.w.s.ServletContextInitializerBeans : Mapping filters: springSecurityFilterChain urls=[/*],
filterRegistrationBean urls=[/account/*], filterRegistrationBean urls=[/api/*], characterEncodingFilter urls=[/*] 2020-01-02 19:35:19.125 DEBUG 61918 [main] o.s.b.w.s.ServletContextInitializerBeans : Mapping servlets: dispatcherServlet urls=[/],
messageDispatcherServlet urls=[/services/*]
从以上日志打印可以看出url拦截已经生效了。
以上代码亲测验证有效。
至于controller的代码拦截试验,此处不方便贴出,请大家各自验证。
