基于maven的springmvc+mybatis的javaweb项目

基于maven的springmvc+mybatis的javaweb项目

利用idea建立基于maven的项目开发步骤,基于tomcat 1.7 和 jdk1.7，idea 2016.1

一、利用idea建立项目的步骤

二、目录结构

java里面存放着代码结构，resources里面存放着配置文件。

jdbc.properties数据库链接数据

logback.xml 日志输出配置

mybatis-config.xml mybatis配置

spring-mybatis.xml mybatis和spring整合配置

spring-mvc.xml spring和springmvc整合配置

配置文件代码

1、jdbc.properties

driver=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/hello?useUnicode=true&characterEncoding=utf8
username=root
password=123456
#定义初始连接数
initialSize=0
#定义最大连接数
maxActive=20
#定义最大空闲
maxIdle=20
#定义最小空闲
minIdle=1
#定义最长等待时间
maxWait=60000

2、logback.xml

<?xml version="1.0" encoding="UTF-8"?>

<configuration debug="true" scan="true" scanPeriod="30 seconds">

<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">      <encoder>
<pattern>%d{yyyy-MM-dd HH:mm:ss} [%thread]  %-5level %logger{36} - %msg%n</pattern>
</encoder>
</appender>
<root level="debug">
<appender-ref ref="STDOUT"/>
</root>
</configuration>

3、mybatis-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">

<configuration>
<settings>
<!--使用jdbc的getGeneratedKeys 获取数据库自增主键值-->
<setting name="useGeneratedKeys" value="true"/>
<!--使用别名替换列名 默认true-->
<setting name="useColumnLabel" value="true"/>
<!--开启驼峰命名转换 Table(create_time) -> Entity(createTime)-->
<setting name="mapUnderscoreToCamelCase" value="true"></setting>
</settings>
</configuration>

4、spring-mybatis.xml

<?xml version="1.0" encoding="UTF-8"?>
