使用idea 搭建SpringMVC+Mybatis



1.  工程目录结构整理

注意在Idea中所有的配置文件都必须放在Resource包中！！ 不然编译器无法编译配置文件(除了web.xml和springMvc-servlet.xml外）

2.  配置mavenPOM.xml文件

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

3.  配置web.xml文件

<?xml version="1.0"encoding="UTF-8"?>
<web-appxmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<url-pattern>/</url-pattern>
</servlet-mapping>

<welcome-file-list>
<welcome-file>/index</welcome-file>
</welcome-file-list>


</web-app>

 

4 . 配置springMvc_servlet.xml文件

 

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

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

5  .配置applicationContext.xml文件

<!--配置声明试事务配置-->

</beans>

6  .配置jdbc.properties文件

jdbc.driver=oracle.jdbc.driver.OracleDriver
jdbc.url=jdbc:oracle:thin:@192.168.161.201:1521:orcl
jdbc.username=fda
jdbc.password=fda

7  .定义一个接口存放增删改查方法

 

如：

8 配置映射User.xml文件

<mappernamespace="com.geok.mapper.UserMapper">

<resultMapid="UserResultMap"type="com.geok.entity.UserInfo">
<resultcolumn="NAME"property="name"jdbcType="VARCHAR"/>
<resultcolumn="PASSWORD"property="password"jdbcType="VARCHAR"/>
<resultcolumn="AGE"property="age"jdbcType="INTEGER"/>
</resultMap>

<selectid="selectUser"resultMap="UserResultMap">
SELECT*FROM USERINFO
</select>
</mapper>

9 .注入Mapper接口的映射类（注入后就可以调用mapper接口中的增删改查方法）

10.启动项目，在controller中调用方法
