API拦截器

import org.springframework.stereotype.Component;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

@Component
public class ApiAuthorityInterceptor implements HandlerInterceptor {

    @Override//在一个请求进入Controller层方法执行前执行这个方法
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        System.out.println(request.getRequestURI()+"aaaaa");
        return true;//方法给予执行，就是允许controller的方法进行执行
        //false 不允许，可以在这之前在reponse中编写返回的结果

    }
    //返回model前
    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
        System.out.println(request.getRequestURI()+"bbb");
    }

    //返回model后
    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {
        //在一个请求处理完毕，即将销毁的时候，执行，可以做一些资源释放之类的工作
    }
}
