1、SSMAOP日志1.數(shù)據(jù)庫與表結(jié)構(gòu)1.1.日志表信息描述sysLog1.2.sql語句CREATE TABLE sysLog(id VARCHAR2(32) default SYS_GUID() PRIMARY KEY,visitTime timestamp, username VARCHAR2(50), ip VARCHAR2(30),url VARCHAR2(50),executionTime int, method VARCHAR2(200)1.3.實體類北京市昌平區(qū)建材城西路 龍辦公樓一層：序號字段名稱字段類型字段描述1idVARCHAR2主鍵 無意義uuid2visitTimetim

5、();/ 獲取 的方法的名稱Object args = jp.getArgs();/ 獲取 的方法的參數(shù)if (args = null | args.length = 0) / 無參數(shù)executionMethod = executionClass.getMethod(methodName); / 只能獲取無參數(shù)方法 else / 有參數(shù)，就將args中所有元素遍歷，獲取對應(yīng)的Class,裝入到一個Class Class classArgs = new Classargs.length;北京市昌平區(qū)建材城西路 龍辦公樓一層：for (int i = 0; i < args.length;

9、(url);/ 獲取ipString ip = request.getRemoteAddr(); sysLog.setIp(ip);/ 可以通過securityContext獲取，也可以從request.getSession中獲取SecurityContext context = SecurityContextHolder.getContext(); / request.getSession().getAttribute("SPRING_SECURITY_CONTEXT")String username = (User) (context.getAuthentication

10、().getPrincipal().getUsername();sysLog.setUsername(username);sysLog.setMethod("類名" + executionClass.getName() + "方法名" + executionMethod.getName();sysLog.setVisitTime(startTime);/ 調(diào)用Service，調(diào)用dao將sysLog insert數(shù)據(jù)庫sysLogService.save(sysLog);在切面類中我們需要獲取登錄用戶的username，還需要獲取ip地址，我們怎么處理？

11、username獲取SecurityContextHolder獲取ip地址獲取ip地址的獲取我們可以通過request.getRemoteAddr()方法獲取到。在Spring中可以通過ReqontextListener來獲取request或session對象。2.3.SysLogControllerRequestMapping("/sysLog") Controllerpublic class SysLogController Autowiredprivate ISysLogService sysLogService;RequestMapping("/findA
