在spring boot1.0+,我们可以使用WebMvcConfigurerAdapter来扩展springMVC的功能,其中自定义的拦截器并不会拦截静态资源(js、css等)。
@Configurationpublic class MyMvcConfig extends WebMvcConfigurerAdapter { @Override public void addViewControllers(ViewControllerRegistry registry) { // super.addViewControllers(registry); //浏览器发送 /atguigu 请求来到 success registry.addViewController("/atguigu").setViewName("success"); } //所有的WebMvcConfigurerAdapter组件都会一起起作用 @Bean //将组件注册在容器 public WebMvcConfigurerAdapter webMvcConfigurerAdapter(){ WebMvcConfigurerAdapter adapter = new WebMvcConfigurerAdapter() { @Override public void addViewControllers(ViewControllerRegistry registry) { registry.addViewController("/").setViewName("login"); registry.addViewController("/index.html").setViewName("login"); registry.addViewController("/main.html").setViewName("dashboard"); } //注册拦截器 @Override public void addInterceptors(InterceptorRegistry registry) { //super.addInterceptors(registry); //静态资源; *.css , *.js //SpringBoot已经做好了静态资源映射 registry.addInterceptor(new LoginHandlerInterceptor()).addPathPatterns("/**") .excludePathPatterns("/index.html","/","/user/login"); } }; return adapter; } @Bean public LocaleResolver localeResolver(){ return new MyLocaleResolver(); } }
在spring boot2.0+以后,WebMvcConfigurerAdapter就过时了,目前通过继承WebMvcConfigurationSupport类(ps:继承后好像MVC自动配置不生效了)或者实现WebMvcConfigurer接口来扩展springMVC的功能。然而该版本自定义的拦截器会拦截静态资源,因此在使用spring2.0+时,配置拦截器之后,我们要把静态资源的路径加入到不拦截的路径之中。
@Configurationpublic class MyMvcConfig implements WebMvcConfigurer{ @Override public void addViewControllers(ViewControllerRegistry registry) { registry.addViewController("/").setViewName("login"); registry.addViewController("/index.html").setViewName("login"); registry.addViewController("/main.html").setViewName("dashboard"); } @Override public void addInterceptors(InterceptorRegistry registry) { //将静态资源排除在拦截之外 registry.addInterceptor(new LoginHandlerInterceptor()).addPathPatterns("/**") .excludePathPatterns("/index.html","/","/user/login","/static/**"); } @Bean public LocaleResolver localeResolver(){ return new MyLocaleResolver(); } }
