切入业务日志

2025-01-20 技术教程

创建接口BizAnnotation.java

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

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

//操作模块
String moduleName();
//操作
String option();

}

标记业务接口StudentService.java

import java.util.List;
import com.shenzhen.management.pojo.Student;
public interface StudentService {
public List<Student> getAllStudents();
@BizAnnotation(moduleName="Student Management",option="Add Student")
public void addStudent(Student student);
}

添加业务接口StudentService.java实现类StudentServiceImpl.java，此处未贴代码。

创建业务日志类BizLogger.java

import java.lang.reflect.Method;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.reflect.MethodSignature;
import com.opensymphony.xwork2.ActionContext;
import com.shenzhen.management.dao.BizLoggerDao;
import com.shenzhen.management.service.BizAnnotation;

public class BizLogger {

private BizLoggerDao bizLoggerDao;

public void log(JoinPoint joinPoint, Object returnObj) {

//方法名
String methodName = joinPoint.getSignature().getName();
//参数
Object[] parameters = joinPoint.getArgs();
//返回值
Object returnValue = returnObj;
//获取模块，操作
Method method = ((MethodSignature)joinPoint.getSignature()).getMethod();
BizAnnotation bizAnnotation = method.getAnnotation(BizAnnotation.class);
String moduleName = bizAnnotation.moduleName();
String option = bizAnnotation.option();
//获取用户ID
String userId = getUserId();
//获取用户IP
String ip = getIP();
//执行插入
bizLoggerDao.saveLog(选择需要保存的数据作为参数);
}

public String getTime()
{
Date now = new Date();
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
String time = dateFormat.format( now );
return time;
}

public String getUserId()
{
Map session = ActionContext.getContext().getSession();
String userId = (String)session.get("userId");
return userId;
}

public String getIP() {

HttpServletRequest request = org.apache.struts2.ServletActionContext.getRequest();

String ip = request.getHeader("x-forwarded-for");
if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getHeader("Proxy-Client-IP");
}
if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getHeader("WL-Proxy-Client-IP");
}
if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getRemoteAddr();
}
return ip;
}

public BizLoggerDao getBizLoggerDao() {
return bizLoggerDao;
}

public void setBizLoggerDao(BizLoggerDao bizLoggerDao) {
this.bizLoggerDao = bizLoggerDao;
}
