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)。
@Configuration
public 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。
@Configuration
public 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();
}
}
