首先搭建後臺環境:
- 先用maven下載依賴包 pom.xml檔案如下:

這個地方因為是簡單的表操作,所以使用逆向工程來生成mapper和mapper.xml 配置檔案如下 generatorConfig.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
"http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

<context id="MysqlTable2" targetRuntime="Mybatis3">

<property name="suppressAllComments" value="true"/>
</commentGenerator>
<!-- 資料庫連線配置 -->

<!--jdbcConnection driverClass="com.mysql.jdbc.Driver"

</javaTypeResolver>
<!--配置生成的實體包

<javaModelGenerator targetPackage="com.HopeRun.SSM.Crm.entity"
targetProject="src/main/java"/>
<!-- 實體包對應對映檔案位置及名稱,預設存放在src目錄下 -->
<sqlMapGenerator targetPackage="mybatis.mappers" targetProject="src/main/resources"/>

</context>

這裡面一定要主要有一個地方就是TargetRunTime這個地方一定要使用mybatis3,因為我改了一下名稱,執行不出來,最後看了文件才生成成功。
2.spring 配置檔案 applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>
