往往一个系统的日志部分也是非常重要的，日志可以用来分析系统出现的异常信息，下面就分享一篇使用spring aop切面来异步添加日志的操作，其中用到了 队列和多线程。
第一步：创建日志对象
import java.util.Date;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
import org.hibernate.annotations.GenericGenerator;
@Entity
@Table(name="t_xt_audit_log")
public class AuditLog
{
@Id
@GenericGenerator(name = "paymentableGenerator", strategy = "assigned")
private String id;
private String description;
private String method;
private Integer type;
@Column(name="request_ip")
private String requestIp;
@Column(name="exception_code")
private String exceptionCode;
@Column(name="exception_detail")
private String exceptionDetail;
private String params;
@Column(name="create_by")
private String createBy;
@Column(name="create_date")
private Date createDate;
@Column(name="app_id")
private String appId;
public String getId()
{
return id;
}
public void setId(String id)
{
this.id = id;
}
public String getDescription()
{
return description;
}
public void setDescription(String description)
{
this.description = description;
}
public String getMethod()
{
return method;
}
public void setMethod(String method)
{
this.method = method;
}
public Integer getType()
{
return type;
}
public void setType(Integer type)
{
this.type = type;
}
public String getRequestIp()
{
return requestIp;
}
public void setRequestIp(String requestIp)
{
this.requestIp = requestIp;
}
public String getExceptionCode()
{
return exceptionCode;
}
public void setExceptionCode(String exceptionCode)
{
this.exceptionCode = exceptionCode;
}
public String getExceptionDetail()
{
return exceptionDetail;
}
public void setExceptionDetail(String exceptionDetail)
{
this.exceptionDetail = exceptionDetail;
}
public String getParams()
{
return params;
}
public void setParams(String params)
{
this.params = params;
}
public String getCreateBy()
{
return createBy;
}
public void setCreateBy(String createBy)
{
this.createBy = createBy;
}
public Date getCreateDate()
{
return createDate;
}
public void setCreateDate(Date createDate)
{
this.createDate = createDate;
}
public String getAppId()
{
return appId;
}
public void setAppId(String appId)
{
this.appId = appId;
}
}第二步：创建存放日志的队列
import java.util.concurrent.BlockingQueue;
import java.util.concurrent.LinkedBlockingQueue;
import java.util.concurrent.TimeUnit;
import org.springframework.stereotype.Component;
import com.izhbg.typz.sso.audit.dto.AuditLog;
@Component
public class AuditLogQueue {
private BlockingQueue<AuditLog> blockingQueue = new LinkedBlockingQueue<AuditLog>();
public void add(AuditLog auditLog) {
blockingQueue.add(auditLog);
}
public AuditLog poll() throws InterruptedException {
return blockingQueue.poll(1, TimeUnit.SECONDS);
}
}第三步：保存日志的线程，从队列中读取日志
import java.util.ArrayList;
import java.util.List;
import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;
import javax.annotation.Resource;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
import com.izhbg.typz.sso.audit.dto.AuditLog;
import com.izhbg.typz.sso.audit.service.AuditLogService;
/**
*
* @ClassName: AuditLogConsumer
* @Description: 日志的保存线程
* @author caixl
* @date 2016-5-11 上午11:23:12
*
*/
@Component
public class AuditLogConsumer implements Runnable{
private static Logger logger = LoggerFactory.getLogger(AuditLogConsumer.class);
public static final int DEFAULT_BATCH_SIZE = 64;
private AuditLogQueue auditLogQueue;
private AuditLogService auditLogService;
private int batchSize = DEFAULT_BATCH_SIZE;
private boolean active = true;
private Thread thread;
@PostConstruct
public void init() {
thread = new Thread(this);
thread.start();
}
@PreDestroy
public void close() {
active = false;
}
public void run() {
while (active) {
execute();
}
}
public void execute() {
List<AuditLog> auditDtos = new ArrayList<AuditLog>();
try {
int size = 0;
while (size < batchSize) {
AuditLog auditLog = auditLogQueue.poll();
if (auditLog == null) {
break;
}
auditDtos.add(auditLog);
size++;
}
} catch (Exception ex) {
logger.info(ex.getMessage(), ex);
}
if (!auditDtos.isEmpty()) {
auditLogService.batchLog(auditDtos);//持久化日志到数据库
}
}
@Resource
public void setAuditLogQueue(AuditLogQueue auditLogQueue) {
this.auditLogQueue = auditLogQueue;
}
@Resource
public void setAuditLogService(AuditLogService auditLogService) {
this.auditLogService = auditLogService;
}
public void setBatchSize(int batchSize) {
this.batchSize = batchSize;
}
}第四步：创建 controller层 自定义注解
import java.lang.annotation.Documented;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
/**
*
* @ClassName: SystemControllerLog
* @Description: 自定义注解 拦截Controller
* @author caixl
* @date 2016-5-10 下午2:16:12
*
*/
@Target({ElementType.PARAMETER, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface SystemControllerLog {
String description() default "";
}第五步：创建service层自定义注解
import java.lang.annotation.Documented;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
/**
*
* @ClassName: SystemServiceLog
* @Description: 自定义注解 拦截service
* @author caixl
* @date 2016-5-10 下午2:17:12
*
*/
@Target({ElementType.PARAMETER, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface SystemServiceLog {
String description() default "";
}第六步：创建切点
import java.lang.reflect.Method;
import java.util.Date;
import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
import net.sf.json.util.JSONUtils;
import org.apache.log4j.Logger;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;
import com.izhbg.typz.base.util.CommonUtil;
import com.izhbg.typz.base.util.IdGenerator;
import com.izhbg.typz.sso.audit.component.AuditLogQueue;
import com.izhbg.typz.sso.audit.dto.AuditLog;
import com.izhbg.typz.sso.audit.manager.AuditLogManager;
import com.izhbg.typz.sso.util.SpringSecurityUtils;
/**
*
* @ClassName: AuditLogAspect
* @Description: 切点类
* @author caixl
* @date 2016-5-10 下午2:50:34
*
*/
@Aspect
@Component
public class AuditLogAspect
{
private AuditLogQueue auditLogQueue;
//本地异常日志记录对象
private static final Logger logger = Logger.getLogger(AuditLogManager.class);
//Service层切点
@Pointcut("@annotation(com.izhbg.typz.sso.annotation.SystemServiceLog)")
public void serviceAspect() {
}
//Controller层切点
@Pointcut("@annotation(com.izhbg.typz.sso.annotation.SystemControllerLog)")
public void controllerAspect() {
}
@Before("controllerAspect()")
public void doBefore(JoinPoint joinPoint) { //@ TODO 异步线程处理
HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
HttpSession session = request.getSession();
//读取session中的用户
//请求的IP
String ip = CommonUtil.getIpAddress(request);
//获取用户请求方法的参数并序列化为JSON格式字符串
String params = "";
if (joinPoint.getArgs() != null && joinPoint.getArgs().length > 0) {
for ( int i = 0; i < joinPoint.getArgs().length; i++) {
params += JSONUtils.valueToString(joinPoint.getArgs()[i]) + ";";
}
}
try {
//*========控制台输出=========*//
System.out.println("=====前置通知开始=====");
System.out.println("请求方法:" + (joinPoint.getTarget().getClass().getName() + "." + joinPoint.getSignature().getName() + "()"));
System.out.println("方法描述:" + getControllerMethodDescription(joinPoint));
System.out.println("请求人:" + SpringSecurityUtils.getCurrentUsername());
System.out.println("请求IP:" + ip);
//*========数据库日志=========*//
AuditLog log = new AuditLog();
log.setId(IdGenerator.getInstance().getUniqTime()+"");
log.setDescription(getControllerMethodDescription(joinPoint));
log.setMethod((joinPoint.getTarget().getClass().getName() + "." + joinPoint.getSignature().getName() + "()"));
log.setType(0);
log.setRequestIp(ip);
log.setExceptionCode( null);
log.setExceptionDetail( null);
log.setParams( params);
log.setCreateBy(SpringSecurityUtils.getCurrentUsername()+"("+SpringSecurityUtils.getCurrentUserId()+")");
log.setCreateDate(new Date());
log.setAppId(SpringSecurityUtils.getCurrentUserAppId());
//保存数据库
auditLogQueue.add(log);
System.out.println("=====前置通知结束=====");
} catch (Exception e) {
//记录本地异常日志
logger.error("==前置通知异常==");
}
}
/**
* 获取注解中对方法的描述信息 用于service层注解
*
* @param joinPoint
* 切点
* @return 方法描述
* @throws Exception
*/
public static String getServiceMthodDescription(JoinPoint joinPoint) throws Exception
{
String targetName = joinPoint.getTarget().getClass().getName();
String methodName = joinPoint.getSignature().getName();
Object[] arguments = joinPoint.getArgs();
Class targetClass = Class.forName(targetName);
Method[] methods = targetClass.getMethods();
String description = "";
for (Method method : methods)
{
if (method.getName().equals(methodName))
{
Class[] clazzs = method.getParameterTypes();
if (clazzs.length == arguments.length)
{
description = method.getAnnotation(SystemServiceLog.class).description();
break;
}
}
}
return description;
}
/**
* 获取注解中对方法的描述信息 用于Controller层注解
*
* @param joinPoint
* 切点
* @return 方法描述
* @throws Exception
*/
public static String getControllerMethodDescription(JoinPoint joinPoint) throws Exception
{
String targetName = joinPoint.getTarget().getClass().getName();
String methodName = joinPoint.getSignature().getName();
Object[] arguments = joinPoint.getArgs();
Class targetClass = Class.forName(targetName);
Method[] methods = targetClass.getMethods();
String description = "";
for (Method method : methods)
{
if (method.getName().equals(methodName))
{

if (clazzs.length == arguments.length)
{
description = method.getAnnotation(SystemControllerLog.class).description();
break;
}
}
}
return description;
}
@Resource
public void setAuditLogQueue(AuditLogQueue auditLogQueue) {
this.auditLogQueue = auditLogQueue;
}
}使用方式:
@RedisCache(type=TXtYh.class,fieldKey="parameterMap.yhId")
@RequestMapping("user-edit")
@SystemControllerLog(description = "编辑用户")
public String userEdit(@RequestParam Map<String, Object> parameterMap, Model model) throws Exception{
String yhId= StringUtils.getString(parameterMap.get("yhId"));
String currentAppId= StringUtils.getString(parameterMap.get("currentAppId"));
TXtYh user = null;
if(StringHelper.isNotEmpty(yhId))
user = tXtYhService.findByYhId(yhId);
String result = tXtJgService.getJgsJSON(currentAppId);
model.addAttribute("user", user);
model.addAttribute("result", result);
model.addAttribute("currentAppId", currentAppId);
List<TXtYy> tXtYyList = tXtYyService.queryAll();
model.addAttribute("txtYy", tXtYyList);
return "admin/guser/getguser";
}
