0、确保通用Mapper被正确配置

1、pom.xml追加

    <properties>

        <targetJavaProject>${basedir}/src/main/java</targetJavaProject>

        <targetResourcesProject>${basedir}/src/main/resources

        </targetResourcesProject>

        <!-- MyBatis Generator mapper接口的生成位置 -->

        <targetMapperPackage>com.spldeolin.demoapp.dao</targetMapperPackage>

        <!-- MyBatis Generator model类的生成位置 -->

        <targetModelPackage>com.spldeolin.demoapp.po</targetModelPackage>

        <!-- MyBatis Generator mapper.xml生成位置 -->

        <targetXMLPackage>mapper</targetXMLPackage>

    </properties>

            <!--Mybatis Generator-->

            <plugin>

                <groupId>org.mybatis.generator</groupId>

                <artifactId>mybatis-generator-maven-plugin</artifactId>

                <version>1.3.6</version>

                <configuration>

                    <configurationFile>

                        ${basedir}/src/main/resources/mybatis/generator-config.xml

                    </configurationFile>

                    <overwrite>false</overwrite>

                    <verbose>true</verbose>

                </configuration>

                <dependencies>

                    <dependency>

                        <groupId>mysql</groupId>

                        <artifactId>mysql-connector-java</artifactId>

                        <version>5.1.43</version>

                    </dependency>

                    <dependency>

                        <groupId>tk.mybatis</groupId>

                        <artifactId>mapper</artifactId>

                        <version>3.4.6</version>

                    </dependency>

                </dependencies>

            </plugin>

2、追加代码生成器配置文件

generator-config.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">

<generatorConfiguration>

    <properties resource="mybatis/db.properties" />

    <context id="Mysql" targetRuntime="MyBatis3Simple" defaultModelType="flat">

        <property name="beginningDelimiter" value="`" />

        <property name="endingDelimiter" value="`" />

        <plugin type="tk.mybatis.mapper.generator.MapperPlugin">

            <!--自定义通用Mapper接口，将来所有生成的mapper接口都会继承这个接口-->

            <property name="mappers"

                    value="com.spldeolin.demoapp.component.Mapper" />

        </plugin>

        <jdbcConnection driverClass="${jdbc.driver}"

                connectionURL="${jdbc.url}"

                userId="${jdbc.username}"

                password="${jdbc.password}">

        </jdbcConnection>

        <javaModelGenerator targetPackage="${targetModelPackage}"

                targetProject="${targetJavaProject}" />

        <sqlMapGenerator targetPackage="${targetXMLPackage}"

                targetProject="${targetResourcesProject}" />

        <javaClientGenerator targetPackage="${targetMapperPackage}"

                targetProject="${targetJavaProject}" type="XMLMAPPER" />

        <table tableName="%">

            <generatedKey column="id" sqlStatement="Mysql" identity="true" />

        </table>

    </context>

</generatorConfiguration>
