2.web工程配置文件`web.xml`

web.xml

<?xml version="1.0" encoding="GBK"?>
<!-- <web-app id="WebApp_ID" version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">  -->

3.数据库的配置文件

pom.xml

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/user
jdbc.username=root
jdbc.password=123
jdbc.maxWait=1000
jdbc.initialSize=20
jdbc.maxActive=100
jdbc.maxIdle=10
jdbc.minIdle=5

4.日志输出格式配置

log4j.properties

#\u5B9A\u4E49LOG\u8F93\u51FA\u7EA7\u522B  
log4j.rootLogger=INFO,Console,File
