springboot自定义页面拦截

 

页面拦截代码

@Configuration                                                                                                  
public class WebConfig implements WebMvcConfigurer {

@Resource
private MyInterceptor myInterceptor;

/**
 * 配置静态访问资源
 * @param registry
 */
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("swagger-ui.html").addResourceLocations("classpath:/META-INF/resources/");
    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
 * @param registry
 */
@Override
public void addViewControllers(ViewControllerRegistry registry) {
    registry.addViewController("/toLogin").setViewName("login");
}

   /**AbstractValidatingSessionManager
    * 拦截器
    * @param registry
    */
   @Override
   public void addInterceptors(InterceptorRegistry registry) {
       // addInterceptor 用于添加拦截规则
       // excludePathPatterns 用户排除拦截
       registry.addInterceptor(myInterceptor).excludePathPatterns(EXCLUDE_PATH_PATTERN);
}

 } 

@Configuration
public class MyInterceptor implements HandlerInterceptor {
