一、配置application.properties

#指定bean所在包,默认值为 /**
mybatis.type-aliases-package=com.neusoft.domain
#指定映射文件
# 默认值为 classpath:/META-INF/resources/,classpath:/resources/,classpath:/static/,classpath:/public/,这里设置要指向的路径，多个使用英文逗号隔开

mybatis.mapperLocations=classpath:mapper/*.xml

二、Spring Boot的pom配置

添加依赖

<dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
            <version>1.0.19</version>
        </dependency>


        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
            <version>1.1.41</version>
        </dependency>
        <dependency>
            <groupId>javax.mail</groupId>
            <artifactId>mail</artifactId>
            <version>1.4.7</version>
        </dependency>
        <dependency>
            <groupId>org.apache.httpcomponents</groupId>
            <artifactId>httpclient</artifactId>
            <version>4.5.5</version>
        </dependency>

        <dependency>
            <groupId>com.belerweb</groupId>
            <artifactId>weibo4j-oauth2</artifactId>
            <version>2.1.1-beta2-3</version>
        </dependency>

三、在resources目录下创建mapper包

将所有的xml文件放置此处

四、mybatis配置文件

<?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">
<generatorConfiguration>
    <!-- 引入配置文件 -->
    <!-- 指定数据连接驱动jar地址 -->
    <classPathEntry  location="D:\MavenRepository\mysql\mysql-connector-java\5.1.30\mysql-connector-java-5.1.30.jar"/>
    <context id="DB2Tables"  targetRuntime="MyBatis3">
        <commentGenerator>
            <!-- 是否去除自动生成的注释 true：是 ： false:否 -->
            <property name="suppressDate" value="true"/>

            <property name="suppressAllComments" value="true"/>
        </commentGenerator>
        <!-- 数据库的相关配置 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://127.0.0.1/community" userId="root" password="root">
        </jdbcConnection>
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>
        <!-- 实体类生成的位置 -->
        <javaModelGenerator targetPackage="com.neusoft.domain" targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>
        <!-- *Mapper.xml 文件的位置 ，targetPackage：包名，targetProject：项目下的路径-->
        <sqlMapGenerator targetPackage="mapper" targetProject="src/main/resources">
            <property name="enableSubPackages" value="true"/>
        </sqlMapGenerator>
        <!-- Mapper 接口文件的位置 -->
        <javaClientGenerator type="XMLMAPPER" targetPackage="com.neusoft.mapper" targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>
        <!-- 配置表信息 -->
        <!--第三方服务类型-->
        <!--<table tableName="tab_user" domainObjectName="User2" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>-->
       <!--xxtable-->
        <!--如果生成n个表，那就将上面的那段table代码copy n份-->
    </context>
</generatorConfiguration>
