1.首先引入依赖,我的2.2.5版本需要引入,但是另一个2.1.5版本是不需要引入就可以使用注解
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-aop</artifactId>
</dependency>
2.创建一个自定义注解类
import java.lang.annotation.*;
/**
* @Auther: DELL
* @Date: 2020/3/26 10:17
* @Description:
*/
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
@Inherited
@Documented
public @interface Log {
String value() default "";
}
3.创建我们的AOP配置class
import com.example.demo.dao.WebBankLogDao;
import com.example.demo.entity.ebbanklog;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.aspectj.lang.reflect.MethodSignature;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.core.LocalVariableTableParameterNameDiscoverer;
import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestAttributes;
import org.springframework.web.context.request.RequestContextHolder;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
import java.lang.reflect.Method;
import java.util.Date;
/**
* @Auther: DELL
* @Date: 2020/3/26 10:06
* @Description:
*/
@Aspect
@Component
public class myAspect {
@Autowired
private WebBankLogDao webBankLogDao;
@Pointcut("@annotation(com.example.demo.aspect.Log)")
public void pointcut() { }
@Around("pointcut()")
public Object around(ProceedingJoinPoint point) {
RequestAttributes requestAttributes = RequestContextHolder.getRequestAttributes();
Object result = null;
long beginTime = System.currentTimeMillis();
try {
// 执行方法
result = point.proceed();
} catch (Throwable e) {
e.printStackTrace();
}
// 执行时长(毫秒)
long time = System.currentTimeMillis() - beginTime;
// 保存日志
saveLog(point, time);
//System.out.println("point=="+point+";time"+time+"Session"+session.getAttribute("loginUser"));
return result;
}
private void saveLog(ProceedingJoinPoint joinPoint, long time) {
MethodSignature signature = (MethodSignature) joinPoint.getSignature();
Method method = signature.getMethod();
ebbanklog sysLog = new ebbanklog();
Log logAnnotation = method.getAnnotation(Log.class);
if (logAnnotation != null) {
// 注解上的描述
sysLog.setOption(logAnnotation.value());
}
// 请求的方法名
String className = joinPoint.getTarget().getClass().getName();
String methodName = signature.getName();
sysLog.setMethod(className + "." + methodName + "()");
// 请求的方法参数值
Object[] args = joinPoint.getArgs();
// 请求的方法参数名称
LocalVariableTableParameterNameDiscoverer u = new LocalVariableTableParameterNameDiscoverer();
String[] paramNames = u.getParameterNames(method);
if (args != null && paramNames != null) {
String params = "";
for (int i = 0; i < args.length; i++) {
params += " " + paramNames[i] + ":" + args[i];
}
sysLog.setParams(params);
}
// 获取request
RequestAttributes requestAttributes = RequestContextHolder.getRequestAttributes();
//从获取RequestAttributes中获取HttpServletRequest的信息
HttpServletRequest request = (HttpServletRequest) requestAttributes.resolveReference(RequestAttributes.REFERENCE_REQUEST);
HttpSession session=request.getSession();
// 设置IP地址
sysLog.setIp(IPUtils.getIpAddr(request));
// 模拟一个用户名
sysLog.setUsercode(session.getAttribute("userCode").toString());
sysLog.setRuntime(Long.toString(time));
sysLog.setCreatetime(new Date());
// 保存系统日志
webBankLogDao.save(sysLog);
}
4.在需要记录的方法地方加上我们的自定义注解,不局限于Controller
5.日志记录在数据库中
建表语句
create table WEBBANKLOG
(
ID NUMBER(12) not null,
USERCODE VARCHAR2(30),
OPTIONS VARCHAR2(200),
RUNTIME NUMBER,
METHOD VARCHAR2(200),
PARAMS VARCHAR2(2000),
IP VARCHAR2(200),
CREATETIME DATE
)
