springboot启动拦截器必须满足三个条件：

1、主配置文件添加@EnableWebMvc注解

2、拦截器继承或实现

3、将配置好的拦截器类添加到springboot配置类中

可参考：[https://blog.csdn.net/open\_yu/article/details/78202723][https_blog.csdn.net_open_yu_article_details_78202723]

### 一、先看下原来xml的配置方式（springMVC） ###

第一步创建一个类实现HandlerInterceptor接口，重写接口的方法。

第二步在XML中进行如下配置，就可以实现自定义拦截器了

### 二、SpringBoot实现自定义拦截器方法： ###

1.首先在启动程序中添加@EnableWebMvc注解，作用是加载配置的类

2.然后在定义的配置类中添加注解（供@EnableWebMvc注解扫描），并加载配置的类

### 以下两个配置类方法配置待研究（主要是路径问题） ###

@Override
    	public void addViewControllers(ViewControllerRegistry registry) {
    		// TODO Auto-generated method stub
    		registry.addViewController("/test").setViewName("/html/**.html");
    		//super.addViewControllers(registry);
    	}
    	
    	@Bean
    	public InternalResourceViewResolver viewResolver() {
    		InternalResourceViewResolver resolver = new InternalResourceViewResolver();
    		resolver.setPrefix("/html");
    		resolver.setSuffix(".html");
    		resolver.setViewClass(JstlView.class);
    		return resolver;
    	}
