采用spring AOP 和注解解决日志

首先创建一个自定义注解

@Target({ElementType.METHOD})@Retention(RetentionPolicy.RUNTIME)public @interface RecordLog {    }

?然后采用spring Aop

@Component("logAround")public class LogAroundInterceptor implements MethodInterceptor {@Autowiredprivate SysLogService sysLogService;private final Logger logger = Logger.getLogger(LogAroundInterceptor.class);public Object invoke(MethodInvocation invocation) throws Throwable {// TODO Auto-generated method stubObject returnObject = invocation.proceed();Method method = invocation.getMethod();if (method.isAnnotationPresent(RecordLog.class)) {Object[] arguments = invocation.getArguments();Object saveObject = null;SysLog sysLog = new SysLog();if (null != arguments) {saveObject = arguments[0];sysLog = getSysLog(getOperaType(method.getName()), saveObject);sysLogService.saveSysLog(sysLog);}}return returnObject;}public int getOperaType(String methodName) {int type = 0;if (methodName.startsWith("save") || methodName.startsWith("add")|| methodName.startsWith("insert")|| methodName.startsWith("update")) {type = 1;} else if (methodName.startsWith("delete")|| methodName.startsWith("del")) {type = 2;}return type;}public SysLog getSysLog(int type, Object object) {SysLog sysLog = new SysLog();sysLog.setCreateTime(new Date());StringBuffer sysContent = new StringBuffer();if (type != 1 && type != 2) {logger.warn("此方法不能被记录日志");return null;}if (object instanceof User) {User user = (User) object;sysContent.append("用户:");if (type == 1) {sysContent.append(user.getUsername()).append("被保存.");} else if (type == 2) {sysContent.append(user.getDeleteUser()).append("删除了用户:" + user.getUniqueUserName());}} else if (object instanceof Tribe) {Tribe tribe = (Tribe) object;if (type == 1) {sysContent.append("用户:").append(tribe.getUser().getUniqueUserName()).append("保存了部落:").append(tribe.getName());} else if (type == 2) {sysContent.append("用户:").append(tribe.getDeleteUser()).append("删除了部落:").append(tribe.getUniqueTribeName());}} else if (object instanceof Assessment) {Assessment assessment = (Assessment) object;int assType = assessment.getType();User user = assessment.getUserByUserId();sysContent.append("用户:").append(user.getUniqueUserName()).append("举报了");if (assType == 1) {sysContent.append("资源").append(assessment.getResource().getTitle());} else if (assType == 2) {sysContent.append("部落").append(assessment.getTribeByAccTribeId().getUniqueTribeName());} else if (assType == 3) {sysContent.append("人").append(assessment.getUserByUserId().getUniqueUserName());}} else if (object instanceof Role) {Role role = (Role) object;sysContent.append("用户:").append(role.getOperaUser());if (type == 1) {sysContent.append("保存了").append(role.getRoleName());} else if (type == 2) {sysContent.append("删除了").append(role.getRoleName());}} else if (object instanceof Resource) {Resource res = (Resource) object;boolean isPass = res.getAppStatus() == 1;sysContent.append("一级审核人员:").append(res.getAppUser().getUniqueUserName());sysContent.append("审核").append(res.getUniqueResName());if (!isPass) {sysContent.append("未通过");} else if (isPass) {sysContent.append("通过");}}logger.info(sysContent.toString());sysLog.setContent(sysContent.toString());return sysLog;}}

?在需要插入注解的方法上面写上@RecordLog就可以啦
