01 idea下快速搭建项目（SSH框架）

1创建项目：

这个就不用讲了，本人创建的是名为bigdata工程

2:配置tomcat服务器：

3：添加名为eshop名称的模块并添加Web application的支持：

4：运行时配置：

添加tomcat服务：

另外在deployment添加：

5：创建index.html运行。即刻

6：给eshop模块中添加maven支持：

修改工件名称：

点击右侧的刷新

7：创建相关包：

8：添加测试依赖，运行测试。

9:在win10mysql中创建eshop数据库和users表：

    a)创建数据库eshop
     登录mysql
$mysql>create database eshop ;

    b)创建users表
$mysql>create table eshop.users(id int primary key auto_increment,name varchar(20),password     varchar(20),regdate datetime) ;

    c)显式表结构

$mysql>desc users;

10：采用c3p0数据源，添加依赖。

11：创建User类：

/**
* User类
*/
public class User {
private Integer id ;
private String name ;
private String password ;
private Date regDate ;
//getXxx/setXxx
}

12：引入新的maven依赖,hibernate.

13：在User类同包下创建User.hbm.xml文件：

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
    <class name="com.chenway.eshop.model.User" table="users">
        <id name="id" column="id" type="integer">
            <generator class="identity"></generator>
        </id>
        <property name="name" column="name" type="string"></property>
        <property name="password" column="password" type="string"></property>
        <property name="regDate" column="regdate" type="date"></property>
    </class>
</hibernate-mapping>

14：引入springframework、mysql依赖：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.17</version>
        </dependency>
    </dependencies>
</project>

15:创建spring配置文件beans.xml 注：采用配置文件外部化，方便维护：

jdbc.properties配置文件：

jdbc.driverclass=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/eshop
jdbc.username=root
jdbc.password=123456

c3p0.pool.size.max=10
c3p0.pool.size.min=2
c3p0.pool.size.ini=3
c3p0.pool.size.increment=2

beans.xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
   <!--指定外部文件的位置-->
    <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
       <property name="location" value="classpath:jdbc.properties"></property>
   </bean>
    <!--c3p0数据源-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="${jdbc.driverclass}"></property>
        <property name="jdbcUrl" value="${jdbc.url}"></property>
        <property name="user" value="${jdbc.username}"></property>
        <property name="password" value="${jdbc.password}"></property>
        <property name="maxPoolSize" value="${c3p0.pool.size.max}"></property>
        <property name="minPoolSize" value="${c3p0.pool.size.min}"></property>
        <property name="initialPoolSize" value="${c3p0.pool.size.ini}"></property>
        <property name="acquireIncrement" value="${c3p0.pool.size.increment}"></property>

    </bean>
</beans>

16:创建测试数据源类：

public class TestDataSource {
    @Test
    public void getConn() throws Exception {
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("beans.xml");
        DataSource dataSource = (DataSource) applicationContext.getBean("dataSource");
        Connection connection = dataSource.getConnection();
        System.out.println(connection);
    }
}

运行输出：

到现在为止，javaee的项目已搭建
