上周接到了一个模块。需要实现Log4j监控 管理员的操作,并且存入数据库中,同时要在JSP页面显示结果,并生成HTML文件。每300条显示生成一条记录。
在经过自己的努力和师父等朋友们的 指导下,完成了。
今天贴出来,和大家分享,有好东西大家开源下,日后学习,都会用的上。
首先,先看log4j插入数据库的操作:
首先项目中导入Log4j的jar,配置好他的log4j.properties文件
Java代码
log4j.rootLogger=WARN,DATABASE
# imporin jdbc.jar
log4j.appender.DATABASE=org.apache.log4j.jdbc.JDBCAppender
# connection
log4j.appender.DATABASE.URL=jdbc:mysql://localhost:3306/test
log4j.appender.DATABASE.driver=com.mysql.jdbc.Driver
log4j.appender.DATABASE.user=root
log4j.appender.DATABASE.password=viken
# sql
log4j.appender.DATABASE.sql=INSERT INTO log4j (Username,Class,Method,CreateTime,LogLevel,MSG) VALUES('%X{userName}','%C,%L','%M','%d{yyyy-MM-dd HH:mm:ss}','%p','%m')
log4j.appender.DATABASE.layout=org.apache.log4j.PatternLayout
log4j.rootLogger=WARN,DATABASE
# imporin jdbc.jar
log4j.appender.DATABASE=org.apache.log4j.jdbc.JDBCAppender
# connection
log4j.appender.DATABASE.URL=jdbc:mysql://localhost:3306/test
log4j.appender.DATABASE.driver=com.mysql.jdbc.Driver
log4j.appender.DATABASE.user=root
log4j.appender.DATABASE.password=viken
# sql
log4j.appender.DATABASE.sql=INSERT INTO log4j (Username,Class,Method,CreateTime,LogLevel,MSG) VALUES('%X{userName}','%C,%L','%M','%d{yyyy-MM-dd HH:mm:ss}','%p','%m')
log4j.appender.DATABASE.layout=org.apache.log4j.PatternLayout
ps:sql 语句:Java代码
log4j.appender.DATABASE.sql=INSERT INTO log4j (Username,Class,Method,CreateTime,LogLevel,MSG) VALUES('%X{userName}','%C,%L','%M','%d{yyyy-MM-dd HH:mm:ss}','%p','%m')
log4j.appender.DATABASE.sql=INSERT INTO log4j (Username,Class,Method,CreateTime,LogLevel,MSG) VALUES('%X{userName}','%C,%L','%M','%d{yyyy-MM-dd HH:mm:ss}','%p','%m')
接下来时在实现类中加入log4j调用。
Java代码
import org.apache.log4j.Logger;
import org.apache.log4j.MDC;
public class DaoImp implements UserDao {
private static Logger log=Logger.getLogger(DaoImp.class);
public void Loign(User us) {
System.out.println("-----------"+us.getUsername()+"登陆啦"+"------------");
MDC.put("userName", us.getUsername());
log.warn("管理员登陆啦~!!!");
}
import org.apache.log4j.Logger;
import org.apache.log4j.MDC;
public class DaoImp implements UserDao {
private static Logger log=Logger.getLogger(DaoImp.class);
public void Loign(User us) {
System.out.println("-----------"+us.getUsername()+"登陆啦"+"------------");
MDC.put("userName", us.getUsername());
log.warn("管理员登陆啦~!!!");
}
以上就完成了log4j的操作部分。
接下来 我们来查询他:
Java代码
public List<Log4j> listall(int pageCount,int begin,int end) {
List<Log4j> list=new ArrayList();
Connection con=null;
Statement stmt=null;
ResultSet rs=null;
DB db=new DB();
String sql="select * from log4j order by CreateTime desc limit "+begin+","+end;
try {
stmt=db.getConnection().createStatement();
rs=stmt.executeQuery(sql);
while(rs.next()){
Log4j lo=new Log4j();
lo.setId(rs.getInt("id"));
lo.setUsername(rs.getString("Username"));
lo.setMethod(rs.getString("Method"));
lo.setClasss(rs.getString("Class"));
lo.setLogLevel(rs.getString("LogLevel"));
lo.setCreateTime(rs.getString("CreateTime"));
lo.setMessage(rs.getString("MSG"));
list.add(lo);
}
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return list;
}
public int getPages(int pageCount) {
int pages = 0;
int allrecorders = 0;
DB db=new DB();
String sql="select count(id) as count from log4j order by CreateTime desc";
Statement stmt=null;
ResultSet rs = null;
try {
stmt=db.getConnection().createStatement();
rs=stmt.executeQuery(sql);
if(rs.next())
allrecorders = rs.getInt("count");
}catch(Exception e)
{
e.printStackTrace();
}
if(pageCount>0)
{
pages = (allrecorders+pageCount-1)/pageCount ;
}
return pages;
}
