SpringBoot登錄用戶權(quán)限攔截器

第SpringBoot登錄用戶權(quán)限攔截器@Override

publicvoidpostHandle(HttpServletRequestrequest,HttpServletResponseresponse,Objecthandler,ModelAndViewmodelAndView)throwsException{

("=====UserAuthInterceptorpostHandle");

@Override

publicvoidafterCompletion(HttpServletRequestrequest,HttpServletResponseresponse,Objecthandler,Exceptionex)throwsException{

("====UserAuthInterceptorafterCompletion");

//記錄日志向文件里面寫日志

//獲取服務(wù)器記錄日志log文件所存放的目錄位置--tomcat下的真實路徑+log目錄

Stringlogdir=request.getServletContext().getRealPath("log");

//路徑不存在就創(chuàng)建

PathlogdirPath=Paths.get(logdir);

if(Files.notExists(logdirPath)){

Files.createDirectories(logdirPath);

//目錄存在就將數(shù)據(jù)[字符]寫入//存放日志的路徑+文件名

Pathlogfile=Paths.get(logdir,"userlog.log");

//logfile.toFile()paths轉(zhuǎn)換為File類型true以追加的方式寫入

BufferedWriterwriter=newBufferedWriter(newFileWriter(logfile.toFile(),true));

//獲取登錄用戶信息

Useruser=(User)request.getSession().getAttribute("loginUser");

//記錄user信息，存入日志

writer.write(newSimpleDateFormat("yyyy-MM-ddHH:mm:ss").format(newDate())+""+user+"\r\n");

writer.flush();

writer.close();

}

2.創(chuàng)建WebMvcConfigurer接口實現(xiàn)類，注冊并生效自定義的攔截器

*addInterceptors方法設(shè)置攔截路徑

*addPathPatterns：需要攔截的訪問路徑

*excludePathPatterns：不需要攔截的路徑，

*String數(shù)組類型可以寫多個用","分割

*@paramregistry

@Override

publicvoidaddInterceptors(InterceptorRegistryregistry){

("========LoginConfig.addInterceptors");

//添加對用戶未登錄的攔截器，并添加排除項

//error路徑，excludePathPatterns排除訪問的路徑在項目中不存在的時候，

//springboot會將路徑變成/error,導(dǎo)致無法進行排除。
