log4j 滚动日志 及 实现操作日志
1、建立log4j.xml 文件
<log4j:configuration>
<appender name="CONSOLE" class="org.apache.log4j.ConsoleAppender">
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern"
value="%d{yyyy-MM-dd HH:mm:ss} [%t] %-5p %c - %m%n" />
layout>
<filter class="org.apache.log4j.varia.LevelRangeFilter">
<param name="LevelMax" value="ERROR"/>
<param name="LevelMin" value="TRACE"/>
filter>
appender>
<appender name="FILE" class="org.apache.log4j.FileAppender">
<param name="File" value="/data/log/error.log"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern"
value="%d{yyyy-MM-dd HH:mm:ss} [%t] %-5p %c - %m%n" />
layout>
<filter class="org.apache.log4j.varia.LevelRangeFilter">
<param name="LevelMax" value="ERROR"/>
<param name="LevelMin" value="TRACE"/>
filter>
appender>
<apender name="ROLLING_FILE" class="org.apache.log4j.RollingFileAppender">
<param name="File" value="/data/log/rolling.log"/>
<param name="Append" value="true"/>
<param name="MaxFileSize" value="1024KB"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern"
value="%d{yyyy-MM-dd HH:mm:ss} [%t] %-5p %c - %m%n" />
layout>
apender>
<appender name="DATABASE" class="com.test.sys.log.MyJDBCAppender">
<param name="Threshold" value="INFO" />
<filter class="com.test.sys.log.CustomWarnLevelFilter">
filter>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern"
value="INSERT INTO account_operate_log (aol_id,operate_type,operate_content,operate_result,user_id,user_name,operate_date,operate_ip,organization) VALUES(UUID(),'%X{operate}','%X{content}',1,%X{userid},'%X{username}',%d{yyyyMMddHHmmss},'%X{ip}','%X{organization}')" />
layout>
appender>
<appender name="ASYNC" class="org.apache.log4j.AsyncAppender">
<param name="BufferSize" value="256" />
<appender-ref ref="ROLLING_FILE" />
<appender-ref ref="FILE" />
appender>
<root>
<priority value="debug" />
<appender-ref ref="CONSOLE" />
<appender-ref ref="FILE" />
<appender-ref ref="ROLLING_FILE" />
<appender-ref ref="DATABASE" />
<appender-ref ref="ASYNC" />
root>
log4j:configuration> 2、com.test.sys.log.MyJDBCAppender 依赖类的实现
import java.sql.Connection;
import java.sql.SQLException;
import org.apache.log4j.jdbc.JDBCAppender;
import org.apache.log4j.spi.ErrorCode;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.alibaba.druid.pool.DruidDataSource;
/**
* @Description MyJDBCAppender.java
* 用于Log4j的数据库Session管理[连接池用Druid]
* @version 1.0
*/
public class MyJDBCAppender extends JDBCAppender
{
/* Druid数据源 */
private static DruidDataSource dataSource;
public MyJDBCAppender() {
super();
}
static{
ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
dataSource= (DruidDataSource) context.getBean("dataSource");
// 这里博主是用的alibaba 的Druid 的连接池 ,原先使用的c3p0连接池，使用此种方式获取不到连接池，而且项目中，c3p0总是关闭连接错误，所以果断改为了Druid ，不失所望，Druid 很好用，效率很高，Druid连接池的配置会贴在此文最后
}
@Override
protected void closeConnection(Connection con) {
try {
/* 如果数据库连接对象不为空和没有被关闭的话，关闭数据库连接 */
if ( con != null && !con.isClosed())
con.close();
} catch (SQLException e) {
errorHandler.error("Error closing MyJDBCAppender.closeConnection() 's connection",e,ErrorCode.GENERIC_FAILURE);
}
}
@Override
protected Connection getConnection() throws SQLException {
return dataSource.getConnection();
}
/* 取消初始化 */
public void uninitialize() {
try {
if (dataSource != null)
dataSource.close();
} finally {
super.close();
}
}
}3、com.test.sys.log.CustomWarnLevelFilter 依赖类的实现
import java.util.regex.Matcher;
import java.util.regex.Pattern;
import org.apache.log4j.spi.LoggingEvent;
import org.slf4j.MDC;
public class CustomWarnLevelFilter extends org.apache.log4j.spi.Filter{
@Override
public int decide(LoggingEvent event) {
//大于等于WARN的日志不允许输出
// if(event.getLevel().toInt() >= Level. WARN.toInt()) {
// return DENY;
// } else {
// return ACCEPT;
// }
event.getMDCCopy();
if(event.getMessage()!=null && isContainChinese(event.getMessage().toString()) && null !=event.getMDC("userid")){
if( isContainGt(event.getMessage().toString())){
String[] split = event.getMessage().toString().split(">");
MDC.put("operate", split[0]+"");
MDC.put("content", event.getMessage().toString()+"");
return ACCEPT;
}else if( event.getMessage().toString().indexOf("登录")>-1 || event.getMessage().toString().indexOf("退出")>-1
|| event.getMessage().toString().indexOf("列表")>-1 || event.getMessage().toString().indexOf("主页")>-1 || event.getMessage().toString().indexOf("导入")>-1){
MDC.put("operate", event.getMessage().toString());
MDC.put("content", event.getMessage().toString());
return ACCEPT;
}else{
return DENY;
}
}else{
return DENY;
}
}
public static boolean isContainChinese(String str) {
Pattern p = Pattern.compile("[\u4e00-\u9fa5]");
Matcher m = p.matcher(str);
if (m.find()) {
return true;
}
return false;
}
public static boolean isContainGt(String str) {
Pattern p = Pattern.compile("(.*)(?:>)");
Matcher m = p.matcher(str);
if (m.find()) {
return true;
}
return false;
}
}4、在登陆的拦截器 中要将 userId 和 企业id 放入MDC 中去，然后在log4j.xml 中 用 %X{userid} 方式可取出其值
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.slf4j.MDC;
import org.springframework.web.method.HandlerMethod;
import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;
public class LoginInterceptor extends HandlerInterceptorAdapter{
private static final Logger LOG = LoggerFactory.getLogger(LoginInterceptor.class);
@Override
public boolean preHandle(HttpServletRequest request,
HttpServletResponse response, Object handler) throws Exception {
HandlerMethod handlerMethod = (HandlerMethod) handler;
if ("GET".equalsIgnoreCase(request.getMethod())) {
}
String requestUri = request.getRequestURI();
LOG.info("requestUri:"+requestUri);
String requestURI = request.getRequestURI();
if(null != request.getSession(false)){
UserInfo user = (UserInfo) request.getSession(false).getAttribute("UserInfo");
if(null == user){
LOG.info("未登录，请先登录");
request.getSession(false).setAttribute("msg", "用户未登录，请先登录");
request.getRequestDispatcher("/pages/login.jsp").forward(request, response);
return false;
}else{
MDC.put("userid", user.getUserId()+"");
MDC.put("username", user.getUserName()+"");
MDC.put("ip", request.getRemoteAddr()+"");
Enterprise enter = (Enterprise) request.getSession(false).getAttribute("Enterprise");
if(null !=user.getOrganizationId()){
MDC.put("organization", enter.getEnterprise()+"");
}else{
MDC.put("organization","");
}
}
}else{
LOG.info("未登录，请先登录");
request.getRequestDispatcher("/pages/login.jsp").forward(request, response);
return false;
}
return true;
}
}
5、applicationContext.xml 中的Druid 连接池的配置
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://********:3306/logistic?useUnicode=true&characterEncoding=utf-8" />
<property name="username" value="****" />
<property name="password" value="****" />
<property name="initialSize" value="5" />
<property name="minIdle" value="10" />
<property name="maxActive" value="20" />
<property name="maxWait" value="60000" />
<property name="timeBetweenEvictionRunsMillis" value="60000" />
<property name="minEvictableIdleTimeMillis" value="300000" />
<property name="validationQuery" value="SELECT 'x'" />
<property name="testWhileIdle" value="true" />
<property name="testOnBorrow" value="false" />
<property name="testOnReturn" value="false" />
<property name="poolPreparedStatements" value="true" />
<property name="maxPoolPreparedStatementPerConnectionSize" value="20" />
<property name="filters" value="stat" />
bean>6、在web.xml 中加入Druid 的监控，启动应用，访问http://localhost/应用名/monitor/ 就可以看到Druid 的监控页面了
<servlet>
<servlet-name>DruidStatViewservlet-name>
<servlet-class>com.alibaba.druid.support.http.StatViewServletservlet-class>
servlet>
<servlet-mapping>
<servlet-name>DruidStatViewservlet-name>
<url-pattern>/monitor/*url-pattern>
