使用maven快速构建SSM项目

这里我就假设大家都已经配置好Maven，就不在重复说明了。若没有配置可以参考《首次使用maven的配置过程》。

1.新建Maven项目

工作区–右键—new—other–搜索maven

现在maven项目新建完毕，需要将其转化为一个动态web项目。

2.将Maven项目转为动态web项目

选中项目—右键–properties—project facets—Dynamic Web Module—（RunTime）Appache Tomcat—…

上面的步骤一般首次都会报如下错误，我们重复刚刚的操作就行

重复步骤如下：注意依然要再次选择Dynamic Web Module ,然后选择 Appache Tomcat，再重复下面的

这样Maven转为Web项目就成功了。现在来配置一下SSM架构了。

3.构建SSM框架

3.1配置pom.xml

3.2配置web.xml

3.3有关Maven与Web基础的配置

选中项目—右键—properties—deployment Assembly–add(目的：让maven的jar映射到web的lib下）

最后，apply —ok保存即可

3.4新建Source Folder

在资源夹是专门用来放置配置文件的

3.5 applicationContext.xml配置

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"

        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory">property>
    bean>

3.6 jdbc.properties配置

# remark
#driver=oracle.jdbc.driver.OracleDriver
#url=jdbc:oracle:thin:@localhost:1521:orcl
#user=test1
#password=test1

#mysql connection
jdbc_driver=com.mysql.jdbc.Driver
jdbc_url=jdbc:mysql://localhost:3306/mybatis
jdbc_user=root
jdbc_password=123

这样使用Maven构建SSM项目就成功来。可以自己可以测试一下。

我的小demo项目–《Maven_SSM_Demo》，项目做了测试，有相关的sql文件，直接可以直接测试。
