拦截器

创建myInterceptor类

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;

public class MyInterceptor1 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 >>> afterHandle");
  }
}

配置拦截器

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
public class MyWebMvcConfig implements WebMvcConfigurer {

  @Override
  public void addInterceptors(InterceptorRegistry registry) {
    registry.addInterceptor(new MyInterceptor1()).addPathPatterns("/**")
        .excludePathPatterns("/hello");
  }
}
