1.话不多说,我们创建一个工程........

2.拷贝pom文件,  里面需要手动配置生成文件的目录,,,,,,记住了,,,

<properties>
            <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
            <targetJavaProject>${basedir}/src/main/java</targetJavaProject>
            <targetMapperPackage>cn.csdn.mapper</targetMapperPackage>      通用mapper,生成的文件位置
            <targetModelPackage>cn.csdn.pojo</targetModelPackage>          pojo生成的文件目录
            
            <targetResourcesProject>${basedir}/src/main/resources</targetResourcesProject>
            <targetXMLPackage>mapper</targetXMLPackage>
            
            <mapper.version>3.4.6</mapper.version>
            <mysql.version>5.1.29</mysql.version>
        </properties>
    
        <dependencies>
            <dependency>
                <groupId>junit</groupId>
                <artifactId>junit</artifactId>
                <version>3.8.1</version>
                <scope>test</scope>
            </dependency>
            <dependency>
                <groupId>tk.mybatis</groupId>
                <artifactId>mapper</artifactId>
                <version>${mapper.version}</version>
            </dependency>
            
            <dependency>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-core</artifactId>
                <version>1.3.2</version>
            </dependency>
    
        </dependencies>
    
        <build>
            <plugins>
                <plugin>
                    <groupId>org.mybatis.generator</groupId>
                    <artifactId>mybatis-generator-maven-plugin</artifactId>
                    <version>1.3.2</version>
                    <configuration>
                        <configurationFile>${basedir}/src/main/resources/generator/generatorConfig.xml</configurationFile>
                        <overwrite>true</overwrite>
                        <verbose>true</verbose>
                    </configuration>
                    <dependencies>
                        <dependency>
                            <groupId>mysql</groupId>
                            <artifactId>mysql-connector-java</artifactId>
                            <version>${mysql.version}</version>
                        </dependency>
                        <dependency>
                            <groupId>tk.mybatis</groupId>
                            <artifactId>mapper</artifactId>
                            <version>${mapper.version}</version>
                        </dependency>
                    </dependencies>
                </plugin>
            </plugins>
        </build>
    </project>

3.在resources创建目录以及文件,

4.配置genertorConfig.xml 配置文件,

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPEgeneratorConfiguration         PUBLIC"-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"         "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd"> <generatorConfiguration>
        <properties resource="config.properties"/>
    
        <context id="Mysql" targetRuntime="MyBatis3Simple" defaultModelType="flat">
            <property name="beginningDelimiter" value="`"/>
            <property name="endingDelimiter" value="`"/>
    
    
                     <plugin type="org.mybatis.generator.plugins.SerializablePlugin"></plugin>
    
            <plugin type="${mapper.plugin}">
                <property name="mappers" value="${mapper.Mapper}"/>
                <property name="forceAnnotation" value="${mapper.forceAnnotation}" />
            </plugin>
    
            <jdbcConnection driverClass="${jdbc.driverClass}"                         connectionURL="${jdbc.url}"                         userId="${jdbc.user}"                         password="${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>

5.resources目录增加config.properties文件,

# 数据库配置 jdbc.driverClass=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/mybatis jdbc.user=root jdbc.password=1039191520 # 通用Mapper固定配置 mapper.plugin=tk.mybatis.mapper.generator.MapperPlugin mapper.Mapper=tk.mybatis.mapper.common.Mapper mapper.forceAnnotation=true

6.最后运行命令,

mybatis-generator:generate

7.错误解决:我运行后,只在resource目录下生成了mapper配置文件,并没有生成mapper 接口啊,啥的, 解决方案步骤如下

1.手动创建一个java目录

最后就生成成功啦,如果还有问题的话,留言出问题所在,
