注：我使用的是外置tomcat启动
注意常见的配置：
.addPathPatterns("/*");
.addPathPatterns("/**");
.addPathPatterns("/user/*");
.addPathPatterns("/api/*");
.addPathPatterns("/**").excludePathPatterns("/login");
有哪些区别

另外spring boot拦截器默认有：
HandlerInterceptorAdapter
AbstractHandlerMapping
UserRoleAuthorizationInterceptor
LocaleChangeInterceptor
ThemeChangeInterceptor

@Configuration
static class WebMvcConfigurer extends WebMvcConfigurerAdapter {
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(new HandlerInterceptorAdapter() {
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
throws Exception {
request.getContextPath();
System.out.println("11111111111 Application.WebMvcConfigurer.interceptor");
return true;
}
}).addPathPatterns("/**");
}
}
}
