如果你想要完全自定义SpringMVC，不保留SpringBoot提供的一切特征，你可以自己定义类并且添加@Configuration注解和@EnableWebMvc
定义一个拦截器
@Component public class MyInterceptor implements HandlerInterceptor { @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception { System.out.println("preHandle method is running!"); return true; } @Override public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception { System.out.println("postHandle method is running!"); } @Override public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception { System.out.println("afterCompletion method is running!"); } }
定义配置类 注册拦截器
@Configuration public class MvcConfiguration implements WebMvcConfigurer { @Autowired private HandlerInterceptor myInterceptor; /** * 重写接口中的addInterceptors方法，添加自定义拦截器 * @param registry */ @Override public void addInterceptors(InterceptorRegistry registry) { registry.addInterceptor(myInterceptor).addPathPatterns("/**"); } }
运行 查看日志
SpringBoot通过logging.level.*=debug来配置日志级别，*填写包名
# 设置org.springframework包的日志级别为debug
logging.level.org.springframework=debug
