页面拦截代码

    registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
}

/**
 * 以前要访问一个页面需要先创建个Controller控制类，再写方法跳转到页面
 * 在这里配置后就不需要那么麻烦了，直接访问http://localhost:8080/toLogin就跳转到login.jsp页面了

@Override

    registry.addViewController("/toLogin").setViewName("login");

   @Override

       // addInterceptor 用于添加拦截规则
       // excludePathPatterns 用户排除拦截
       registry.addInterceptor(myInterceptor).excludePathPatterns(EXCLUDE_PATH_PATTERN);
