废话不多说，直接上代码，相信都能看的懂
一共两布，第一步，创建拦截器拦截
包com.cy.example.config; import javax.servlet.http.httpservletrequest; import javax.servlet.http.httpservletresponse; import javax.serv.servlet.servlet.http.httpp.httpsession; org.springframework.web.servlet.handlerinterceptor; import org.springframework.web.servlet.modelandview; public class class loginInterceptor insterlersports handlerintercements handlerIntercters handlerInterInterpector {private logger logger = loggerfactory.getLogger.getLogger（loginInterpector.class.class.class）; public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception { // TODO Auto-generated method stub } public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception { // TODO Auto-generated方法stub} public boolean prehandle（httpservletrequest请求，httpservletresponse响应，对象处理程序）抛出异常{// todo auto-generated方法stub ///////////////////////////////////////////////////// // logger.info（“ -----进入登录拦截器-url：”+request.getServletPath（）+“ -----”）; if（session.getAttribute（webconfig.login_user）== null）{logger.info（“ -------- login login ligin页面------”）; wenspy.SendRedirect（request.getContextPath（）+“/index”）;返回false; } else {session.setAttribute（webconfig.login_user，session.getAttribute（webconfig.login_user）））;返回true; }}}}第二步，注册创建的拦截器
com.cy.cy.example.config; import org.springframework.context.annotation.configuration; import org.springframework.web.servlet.servlet.config.config.annotation.defeftservleservletservlethertservlethandlerconfigurer; org.springframework.web.servlet.config.annotation.resourcehandlerRegist; import org.springframework.web.servlet.config.config.annotation.webmvcconfigurerAdapter; @configurationpublic class exter “登录器”； public webconfig（）{super（）; } //因为新加了拦截器，这里需要重新设置资源地址 @ @override public void addresourcehandlers（resourceHandlerRegistry registry）{guberistry.addresourcehandler（“/static/**”）。addResourcelcelacation（“ classpath：classpath：/static/static/”）; registry.AddresourceHandler（“/templates/**”）。addResourcelocations（“ classPath：/templates/”）; Super.AddresourceHandlers（注册表）； } @Override public void configuredEfaultServleThandling（DefaultServleServleServleServleServleslerConfigurer configurer）{configurer.enable（）; } @Override公共void addInterceptors（interceptorRegistry registry）{//拦截规则：login，其他都拦截判断，dubludepathPatterns是排除拦截的路径，一个是登录验证地址super.addinterceptors（注册表）; }}}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。，也希望大家多多支持武林网。
