扩展默认的spirngMVC功能

步骤

1、使用@Configuration标注为配置类
2、实现WebMvcConfigurer接口
3、 根据需要实现接口方法

代码

CustomMvcConfig

@Configurationpublic class CustomMvcConfig implements WebMvcConfigurer { ???//自定义拦截器 ???@Override ???public void addInterceptors(InterceptorRegistry registry) { ???????registry.addInterceptor(new MyInterceptor()).addPathPatterns("/**").excludePathPatterns("/test1"); ???} ???//访问/showLogin时跳转到login视图 ???@Override ???public void addViewControllers(ViewControllerRegistry registry) { ???????registry.addViewController("/showLogin").setViewName("login"); ???} ???}

MyInterceptor

public class MyInterceptor implements HandlerInterceptor { ???@Override ???public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) ???????????throws Exception { ???????System.out.println("MyInterceptor.preHandle"); ???????return true; ???} ???@Override ???public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ???????????ModelAndView modelAndView) throws Exception { ???????System.out.println("MyInterceptor.postHandle"); ???} ???@Override ???public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) ???????????throws Exception { ???????System.out.println("MyInterceptor.afterCompletion"); ???}}
