**1、创建SpringBoot工程**

**2、模块选择**

**3、pom文件**

            </plugins>
        </build>
    
    </project>

**4、application.yml配置文件**

spring:
      datasource:
        username: root
        password: 5808074wujiajun
        url: jdbc:mysql://localhost:3306/springboot_library?characterEncoding=utf-8
        driver-class-name: com.mysql.jdbc.Driver
    mybatis:
      mapper-locations: classpath:mappers/*.xml # mapper映射文件路径
      type-aliases-package: com.example.springbootlibrary.pojo # 实体类路径

**5、generator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>
        
        <classPathEntry  location="C:\Users\jdbc\5.1.6\mysql-connector-java-5.1.6.jar"/>
        <context id="DB2Tables"  targetRuntime="MyBatis3">
            <commentGenerator>
                <property name="suppressDate" value="true"/>
                
                <property name="suppressAllComments" value="true"/>
            </commentGenerator>
            
            <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/springboot_library?characterEncoding=utf-8" userId="root" password="5808074wujiajun">
            </jdbcConnection>
            <javaTypeResolver>
                <property name="forceBigDecimals" value="false"/>
            </javaTypeResolver>
            
            <javaModelGenerator targetPackage="com.example.springbootlibrary.pojo" targetProject="src/main/java">
                <property name="enableSubPackages" value="true"/>
                <property name="trimStrings" value="true"/>
            </javaModelGenerator>
            
            <sqlMapGenerator targetPackage="mappers" targetProject="src/main/resources">
                <property name="enableSubPackages" value="true"/>
            </sqlMapGenerator>
            
            <javaClientGenerator type="XMLMAPPER" targetPackage="com.example.springbootlibrary.dao" targetProject="src/main/java">
                <property name="enableSubPackages" value="true"/>
            </javaClientGenerator>
            
            <table tableName="user" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
            <table tableName="admin" domainObjectName="Admin" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
            <table tableName="book" domainObjectName="Book" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false">
                <columnOverride column="icon" jdbcType="VARCHAR"></columnOverride>
            </table>
            <table tableName="record" domainObjectName="Record" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
            <table tableName="black_list" domainObjectName="BlackList" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
        </context>
    </generatorConfiguration>

**6、启动generator插件**

**7、运行成功**

**8、项目包结构**

**9、想要使用Mybatis还要在启动类加上扫描dao层接口文件的注解@MapperScan**
