一、自定义拦截器实现 HandlerInterceptor 接口
/** * * Created by zhh on 2018/04/20. */public class MyInterceptor implements HandlerInterceptor { @Autowired private NetworkProxyInfoService networkProxyInfoService; @Override public void afterCompletion(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2, Exception arg3) throws Exception { // TODO Auto-generated method stub } @Override public void postHandle(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2, ModelAndView arg3) throws Exception { networkProxyInfoService.getAllNetworkProxyInfoByIsValid(GobalConstant.ProxyValid.VALID); } @Override public boolean preHandle(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2) throws Exception { // TODO Auto-generated method stub return true; }}二、自定义拦截器配置
/** * * Created by zhh on 2018/04/20. */@Configurationpublic class MyWebMvcConfig extends WebMvcConfigurerAdapter { /** * 将自定义拦截器作为Bean写入配置 * @return */ @Bean public MyInterceptor myInterceptor() { return new MyInterceptor(); } @Override public void addInterceptors(InterceptorRegistry registry) { /** * 多个拦截器组成一个拦截器链 * addPathPatterns 用于添加拦截规则 * excludePathPatterns 用户排除拦截 */ registry.addInterceptor(myInterceptor()).addPathPatterns("/**"); super.addInterceptors(registry); } }以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持武林网。
