背景
系统出现数据莫名丢失,业务人员的反馈无法复现问题。纠结了很久,最终老板发话要记录操作,通过日志进行分析重现
环境
SSH框架
目标
1、记录访问了那个方法,使用的参数及返回的内容
2、记录新增、修改、删除的数据持久化记录
关键
监听器(Interceptor)
实现
1、访问记录,使用Struts的MethodFilterInterceptor监听器
import org.apache.log4j.Logger;
import org.apache.struts2.ServletActionContext;
import org.codehaus.jackson.map.ObjectMapper; import com.opensymphony.xwork2.ActionInvocation;
import com.opensymphony.xwork2.interceptor.MethodFilterInterceptor;
/**
* Action方法监听
* @author ZhangLi
* @date 2018年8月28日 下午4:42:57
*/
public class MethodInterceptor extends MethodFilterInterceptor { private static final long serialVersionUID = 1L; @SuppressWarnings("rawtypes")
@Override
protected String doIntercept(ActionInvocation AI) throws Exception {
String result = null;
Logger logger = null;
try{
result = AI.invoke();
String methodName = AI.getProxy().getMethod();
if (methodName.length() > 0) {
Object action = AI.getAction();
Class clazz = action.getClass();
logger = Logger.getLogger(clazz);
ObjectMapper mapper = new ObjectMapper(); StringBuilder sbInfo = new StringBuilder();
sbInfo.append("[ Log ] 操作记录 (Start)");
sbInfo.append("\n");
sbInfo.append(String.format("访问后台:%s访问[%s]类[%s]方法",ServletActionContext.getRequest().getRemoteAddr(),clazz.getName(),methodName));
sbInfo.append("\n");
sbInfo.append(String.format("访问URL:%s",ServletActionContext.getRequest().getRequestURI()));
sbInfo.append("\n");
sbInfo.append(String.format("访问参数:%s",mapper.writeValueAsString(ServletActionContext.getRequest().getParameterMap())));
sbInfo.append("\n");
sbInfo.append(String.format("返回结果:%s",result));
sbInfo.append("\n");
sbInfo.append("[ Log ] 操作记录 (End)"); logger.warn(sbInfo);
}
}catch(Exception e){
logger.error("Log - 访问错误", e);
}
return result;
} }
struts.xml配置
<package name="default" extends="json-default" namespace="/">
<!-- 配置拦截器和拦截器栈 -->
<interceptors>
<interceptor name="methodInterceptor" class="com.ytforever.interceptor.MethodInterceptor">
</interceptor>
<interceptor-stack name="methodStack">
<interceptor-ref name="methodInterceptor"></interceptor-ref>
</interceptor-stack>
</interceptors>
<!-- 默认拦截器 -->
<default-interceptor-ref name="methodStack"></default-interceptor-ref>
</package>
<!-- 假如多个package,每个首行拷贝默认拦截器,不然,方法不被监听,无法记录 -->
<!-- 默认拦截器 -->
<default-interceptor-ref name="methodStack"></default-interceptor-ref>
2、数据库持久化记录,使用hibernate的EventListener事件监听
import org.apache.log4j.Logger;
import org.codehaus.jackson.map.ObjectMapper;
import org.hibernate.event.PostDeleteEvent;
import org.hibernate.event.PostDeleteEventListener;
import org.hibernate.event.PostInsertEvent;
import org.hibernate.event.PostInsertEventListener;
import org.hibernate.event.PostUpdateEvent;
import org.hibernate.event.PostUpdateEventListener;
/**
* HIBERNATE删除、修改监听
* @author ZhangLi
* @date 2018年8月28日 下午4:44:26
*/
public class UpdateDeleteListener implements PostInsertEventListener,PostUpdateEventListener, PostDeleteEventListener { private static final long serialVersionUID = 1L;
Logger logger = null;
ObjectMapper mapper = new ObjectMapper(); @Override
public void onPostDelete(PostDeleteEvent PD) {
try {
logger = Logger.getLogger(PD.getEntity().getClass()); StringBuffer sbInfo = new StringBuffer();
sbInfo.append("[ Data ] 删除数据 (Start)");
sbInfo.append("\n");
sbInfo.append(String.format("实体名:%s", PD.getEntity().getClass().getName()));
sbInfo.append("\n");
sbInfo.append(String.format("主键值:%s", PD.getId()));
sbInfo.append("\n");
sbInfo.append(String.format("表字段:%s", mapper.writeValueAsString(PD.getPersister().getPropertyNames())));
sbInfo.append("\n");
sbInfo.append(String.format("删数据:%s",mapper.writeValueAsString(PD.getDeletedState())));
sbInfo.append("\n");
sbInfo.append("[ Data ] 删除数据 (End)"); logger.warn(sbInfo);
} catch (Exception e) {
logger.error("[ Data ] 删除数据失败", e);
} } @Override
public void onPostUpdate(PostUpdateEvent PU) {
try {
logger = Logger.getLogger(PU.getEntity().getClass()); StringBuffer sbInfo = new StringBuffer();
sbInfo.append("[ Data ] 修改数据 (Start)");
sbInfo.append("\n");
sbInfo.append(String.format("实体名:%s", PU.getEntity().getClass().getName()));
sbInfo.append("\n");
sbInfo.append(String.format("修改前:%s",mapper.writeValueAsString(PU.getOldState())));
sbInfo.append("\n");
sbInfo.append(String.format("修改后:%s",mapper.writeValueAsString(PU.getEntity())));
sbInfo.append("\n");
sbInfo.append("[ Data ] 修改数据 (End)"); logger.warn(sbInfo);
} catch (Exception e) {
logger.error("[ Data ] 数据修改失败", e);
}
} @Override
public void onPostInsert(PostInsertEvent PI) {
try {
logger = Logger.getLogger(PI.getEntity().getClass()); StringBuffer sbInfo = new StringBuffer();
sbInfo.append("[ Data ] 新增数据 (Start)");
sbInfo.append("\n");
sbInfo.append(String.format("实体名:%s", PI.getEntity().getClass().getName()));
sbInfo.append("\n");
sbInfo.append(String.format("表字段:%s", mapper.writeValueAsString(PI.getPersister().getPropertyNames())));
sbInfo.append("\n");
sbInfo.append(String.format("新增的数据:%s",mapper.writeValueAsString(PI.getState())));
sbInfo.append("\n");
sbInfo.append("[ Data ] 新增数据 (End)"); logger.warn(sbInfo);
} catch (Exception e) {
logger.error("[ Data ] 新增数据失败", e);
}
} }
applicationContext.xml文件配置
<bean id="auditlogEvent" class="com.ytforever.interceptor.UpdateDeleteListener"></bean>
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<!-- 注入数据源 -->
<property name="dataSource" ref="dataSource" />
<!-- 设置Spring取那个包中查找相应的实体类 -->
<property name="packagesToScan">
<value>com.ytforever.bean,com.ytforever.workflow.bean</value>
</property>
<property name="hibernateProperties">

效果
小结
想完成系统访问记录、数据操作记录,重现操作过程。选用框架监听,完成记录,非常好使。
