拦截器-接口配置拦截器

接口配置拦截器

根据配置的接口拦截对应的接口（addPathPatterns），过滤拦截接口（excludePathPatterns）

拦截接口配置

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

import javax.annotation.Resource;

/***
 *  拦截器配置
 *  @author 陈植斌
 *  @date 2022/10/20 11:27
 */
@Configuration
public class WebConfig implements WebMvcConfigurer {

    @Resource
    ControlInterceptor interceptor;

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        // 添加拦截器，配置拦截地址
        //1.游客可以进入查看游戏
        //2.play进入接口再验证合法性
        //3.第3方回调不在过滤器验证合法性，前端发起支付请求时也不需要过滤验证
//        addPathPatterns 拦截接口
//        excludePathPatterns 过滤接口
        registry.addInterceptor(interceptor)
                .addPathPatterns("/HelloWord/**", "/sdkLogin/token")
                .excludePathPatterns("/error/**", "/HelloWord/getUrl");
    }
}

拦截逻辑处理

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
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;

/***
 *  拦截器操作类
 *  拦截下来后进行操作
 *
 *  @author 陈植斌
 *  @date 2022/10/20 12:04
 */
@Component
public class ControlInterceptor implements HandlerInterceptor {

    private final Logger logger = LoggerFactory.getLogger(ControlInterceptor.class);

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object object) throws Exception {
        logger.info("进入拦截器");
        return true;
    }

    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object object, ModelAndView modelAndView){
        System.out.println("postHandle");
    }

    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object object, Exception exception){
        System.out.println("afterCompletion");
    }

}
