设计原则和思路:
元注解方式结合AOP,灵活记录操作日志能够记录详细错误日志为运维提供支持日志记录尽可能减少性能影响1.定义日志记录元注解
package com.myron.ims.annotation;import java.lang.annotation.*;/** * 自定义注解 拦截Controller * * @author lin.r.x * */@Target({ ElementType.PARAMETER, ElementType.METHOD })@Retention(RetentionPolicy.RUNTIME)public @interface SystemControllerLog { /** * 描述业务操作 例:Xxx管理-执行Xxx操作 * @return */ String description() default "";}2.定义用于记录日志的实体类
package com.myron.ims.bean;import java.io.Serializable;import com.myron.common.util.StringUtils;import com.myron.common.util.UuidUtils;import com.fasterxml.jackson.annotation.JsonFormat;import java.util.Date;import java.util.Map;/** * 日志类-记录用户操作行为 * @author lin.r.x * */public class Log implements Serializable{ private static final long serialVersionUID = 1L; private String logId; //日志主键 private String type; //日志类型 private String title; //日志标题 private String remoteAddr; //请求地址 private String requestUri; //URI private String method; //请求方式 private String params; //提交参数 private String exception; //异常 @JsonFormat(pattern="yyyy-MM-dd HH:mm:ss", timezone = "GMT+8") private Date OperateDate; //开始时间 private String timeout; //结束时间 private String userId; //用户ID public String getLogId() { return StringUtils.isBlank(logId) ? logId : logId.trim(); } public void setLogId(String logId) { this.logId = logId; } public String getType() { return StringUtils.isBlank(type) ? type : type.trim(); } public void setType(String type) { this.type = type; } public String getTitle() { return StringUtils.isBlank(title) ? title : title.trim(); } public void setTitle(String title) { this.title = title; } public String getRemoteAddr() { return StringUtils.isBlank(remoteAddr) ? remoteAddr : remoteAddr.trim(); } public void setRemoteAddr(String remoteAddr) { this.remoteAddr = remoteAddr; } public String getRequestUri() { return StringUtils.isBlank(requestUri) ? requestUri : requestUri.trim(); } public void setRequestUri(String requestUri) { this.requestUri = requestUri; } public String getMethod() { return StringUtils.isBlank(method) ? method : method.trim(); } public void setMethod(String method) { this.method = method; } public String getParams() { return StringUtils.isBlank(params) ? params : params.trim(); } public void setParams(String params) { this.params = params; } /** * 设置请求参数 * @param paramMap */ public void setMapToParams(Map<String, String[]> paramMap) { if (paramMap == null){ return; } StringBuilder params = new StringBuilder(); for (Map.Entry<String, String[]> param : ((Map<String, String[]>)paramMap).entrySet()){ params.append(("".equals(params.toString()) ? "" : "&") + param.getKey() + "="); String paramValue = (param.getValue() != null && param.getValue().length > 0 ? param.getValue()[0] : ""); params.append(StringUtils.abbr(StringUtils.endsWithIgnoreCase(param.getKey(), "passWord") ? "" : paramValue, 100)); } this.params = params.toString(); } public String getException() { return StringUtils.isBlank(exception) ? exception : exception.trim(); } public void setException(String exception) { this.exception = exception; } public Date getOperateDate() { return operateDate; } public void setOperateDate(Date operateDate) { this.operateDate = operateDate; } public String getTimeout() { return StringUtils.isBlank(timeout) ? timeout : timeout.trim(); } public void setTimeout(String timeout) { this.timeout = timeout; } public String getUserId() { return StringUtils.isBlank(userId) ? userId : userId.trim(); } public void setUserId(String userId) { this.userId = userId; }}3.定义日志AOP切面类
package com.myron.ims.aop;import java.lang.reflect.Method;import java.text.SimpleDateFormat;import java.util.Date;import java.util.Map;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.Httpsession;import org.aspectj.lang.JoinPoint;import org.aspectj.lang.annotation.After;import org.aspectj.lang.annotation.AfterThrowing;import org.aspectj.lang.annotation.Aspect;import org.aspectj.lang.annotation.Before;import org.aspectj.lang.annotation.Pointcut;import org.aspectj.lang.reflect.MethodSignature;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.core.NamedThreadLocal;import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;import org.springframework.stereotype.Component;import com.myron.common.util.DateUtils;import com.myron.common.util.UuidUtils;import com.myron.ims.annotation.SystemControllerLog;import com.myron.ims.annotation.SystemServiceLog;import com.myron.ims.bean.Log;import com.myron.ims.bean.User;import com.myron.ims.service.LogService;/** * 系统日志切面类 * @author lin.r.x * */@Aspect@Componentpublic class SystemLogAspect { private static final Logger logger = LoggerFactory.getLogger(SystemLogAspect. class); private static final ThreadLocal<Date> beginTimeThreadLocal = new NamedThreadLocal<Date>("ThreadLocal beginTime"); private static final ThreadLocal<Log> logThreadLocal = new NamedThreadLocal<Log>("ThreadLocal log"); private static final ThreadLocal<User> currentUser=new NamedThreadLocal<>("ThreadLocal user"); @Autowired(required=false) private HttpServletRequest request; @Autowired private ThreadPoolTaskExecutor threadPoolTaskExecutor; @Autowired private LogService logService; /** * Controller层切点 注解拦截 */ @Pointcut("@annotation(com.myron.ims.annotation.SystemControllerLog)") public void controllerAspect(){} /** * 前置通知 用于拦截Controller层记录用户的操作的开始时间 * @param joinPoint 切点 * @throws InterruptedException */ @Before("controllerAspect()") public void doBefore(JoinPoint joinPoint) throws InterruptedException{ Date beginTime=new Date(); beginTimeThreadLocal.set(beginTime);//线程绑定变量(该数据只有当前请求的线程可见) if (logger.isDebugEnabled()){//这里日志级别为debug logger.debug("开始计时: {} URI: {}", new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS") .format(beginTime), request.getRequestURI()); } //读取session中的用户 HttpSession session = request.getSession(); User user = (User) session.getAttribute("ims_user"); currentUser.set(user); } /** * 后置通知 用于拦截Controller层记录用户的操作 * @param joinPoint 切点 */ @SuppressWarnings("unchecked") @After("controllerAspect()") public void doAfter(JoinPoint joinPoint) { User user = currentUser.get(); if(user !=null){ String title=""; String type="info"; //日志类型(info:入库,error:错误) String remoteAddr=request.getRemoteAddr();//请求的IP String requestUri=request.getRequestURI();//请求的Uri String method=request.getMethod(); //请求的方法类型(post/get) Map<String,String[]> params=request.getParameterMap(); //请求提交的参数 try { title=getControllerMethodDescription2(joinPoint); } catch (Exception e) { e.printStackTrace(); } // 打印JVM信息。 long beginTime = beginTimeThreadLocal.get().getTime();//得到线程绑定的局部变量(开始时间) long endTime = System.currentTimeMillis(); //2、结束时间 if (logger.isDebugEnabled()){ logger.debug("计时结束:{} URI: {} 耗时: {} 最大内存: {}m 已分配内存: {}m 已分配内存中的剩余空间: {}m 最大可用内存: {}m", new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS").format(endTime), request.getRequestURI(), DateUtils.formatDateTime(endTime - beginTime), Runtime.getRuntime().maxMemory()/1024/1024, Runtime.getRuntime().totalMemory()/1024/1024, Runtime.getRuntime().freeMemory()/1024/1024, (Runtime.getRuntime().maxMemory()-Runtime.getRuntime().totalMemory()+Runtime.getRuntime().freeMemory())/1024/1024); } Log log=new Log(); log.setLogId(UuidUtils.creatUUID()); log.setTitle(title); log.setType(type); log.setRemoteAddr(remoteAddr); log.setRequestUri(requestUri); log.setMethod(method); log.setMapToParams(params); log.setUserId(user.getId()); Date operateDate=beginTimeThreadLocal.get(); log.setOperateDate(operateDate); log.setTimeout(DateUtils.formatDateTime(endTime - beginTime)); //1.直接执行保存操作 //this.logService.createSystemLog(log); //2.优化:异步保存日志 //new SaveLogThread(log, logService).start(); //3.再优化:通过线程池来执行日志保存 threadPoolTaskExecutor.execute(new SaveLogThread(log, logService)); logThreadLocal.set(log); } } /** * 异常通知 记录操作报错日志 * @param joinPoint * @param e */ @AfterThrowing(pointcut = "controllerAspect()", throwing = "e") public void doAfterThrowing(JoinPoint joinPoint, Throwable e) { Log log = logThreadLocal.get(); log.setType("error"); log.setException(e.toString()); new UpdateLogThread(log, logService).start(); } /** * 获取注解中对方法的描述信息 用于service层注解 * @param joinPoint切点 * @return discription */ public static String getServiceMthodDescription2(JoinPoint joinPoint) { MethodSignature signature = (MethodSignature) joinPoint.getSignature(); Method method = signature.getMethod(); SystemServiceLog serviceLog = method .getAnnotation(SystemServiceLog.class); String discription = serviceLog.description(); return discription; } /** * 获取注解中对方法的描述信息 用于Controller层注解 * * @param joinPoint 切点 * @return discription */ public static String getControllerMethodDescription2(JoinPoint joinPoint) { MethodSignature signature = (MethodSignature) joinPoint.getSignature(); Method method = signature.getMethod(); SystemControllerLog controllerLog = method .getAnnotation(SystemControllerLog.class); String discription = controllerLog.description(); return discription; } /** * 保存日志线程 */ private static class SaveLogThread implements Runnable { private Log log; private LogService logService; public SaveLogThread(Log log, LogService logService) { this.log = log; this.logService = logService; } @Override public void run() { logService.createLog(log); } } /** * 日志更新线程 */ private static class UpdateLogThread extends Thread { private Log log; private LogService logService; public UpdateLogThread(Log log, LogService logService) { super(UpdateLogThread.class.getSimpleName()); this.log = log; this.logService = logService; } @Override public void run() { this.logService.updateLog(log); } }}4.spring 配置扫描切面,开启@AspectJ注解的支持
<!-- 启动对@AspectJ注解的支持 --> <aop:aspectj-autoproxy/> <!-- 扫描切点类组件 --> <context:component-scan base-package="com.myron.ims.aop" /> <context:component-scan base-package="com.myron.ims.service"/> <bean id="taskExecutor" class="org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor"> <property name="corePoolSize" value="5" /> <property name="maxPoolSize" value="10" /> <property name="WaitForTasksToCompleteOnShutdown" value="true" /> </bean>5.使用范例LoginController方法中添加日志注解
/** *系统登入 */ @RequestMapping("/login.do") @SystemControllerLog(description="登入系统") @ResponseBody public Map<String, Object> login(String username, String password, Boolean rememberMe, HttpServletRequest req){ //业务代码省略...} /** * 安全退出登入 * @return */ @SystemControllerLog(description="安全退出系统") @RequestMapping("logout.do") public String logout(){ Subject subject=SecurityUtils.getSubject(); if(subject.isAuthenticated()){ subject.logout(); // session 会销毁,在SessionListener监听session销毁,清理权限缓存 } return "/login.jsp"; }6.运行效果
