Maven+ssm（spring、springmvc、mybatis）开发Web应用

来源：互联网发布：淘宝上最帅的男模特编辑：程序博客网时间：2024/06/07 01:00

最近自己一直在学习javeEE开发的基础知识，最近自己学习如何用Maven和ssm框架整合开发web应用；

Maven的安装这里就不再讲解了，如果不清楚的可以看我的另一篇文章win7安装Maven插件

我使用Eclipse开发的，MyEclipse大概差不多。

1.首先集成tomcat

点击“Window-Preferences-Runtime Environments”

2.创建Maven-web应用

首先给eclipse配置Maven

点击“Window-Preferences-Maven”

选择Maven文件的路径；

选中刚才添加的那个Maven文件，点击apply

设置User Settings ，如下图，将Maven文件中conf文件下的settings.xml文件路径选择上去，点击apply；

Maven的配置完成了

到此准备工作算是做好了，下面就是开始创建工程了

--1、

这里报该错误不要管，没有事的

然后在src-webapp下面添加一些文件和文件夹，如下：

接下来建dao、service、model、action包，几个配置的xml文件和mapper文件夹

现在就是要去配置各个xml文件了：

pom.xml文件：

保存之后，要右击工程名，Maven-Upload Project；

在com.model包下建一个UserModel；

mybatiscfg.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">

    </typeAliases>
    <mappers>
        <mapper resource="Mappers/FindUserMapper.xml" />
    </mappers>
</configuration>

bean.xml:

             <property name="user" value="root"/>

      <bean id="dataSourceTransactionManagerID" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
             <property name="dataSource" ref="dataSource"/>
      </bean>
</beans>

application.xml:(其实要是简单的demo，可以不用配置的)

web.xml：

</web-app>

FindUserMapper.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="Maven001">

    <select id="findUser" parameterType="int" resultType="User">
        select * from user_info where userId = #{13}
    </select>

</mapper>

至此xml文件就都配置完成了，现在就是编写service、dao、action等类了；

FindUserDao:

UserModel:

FindUserService:

FindUserAction:

现在部署到tomcat中；

在浏览器输入如图所示：

大功告成。。。
