mybatis自动生成实体xml--generator

1.

resources目录下创建 mybatis-generator文件夹，并添加generatorConfig.xml 文件。

2.

粘进去
修改 mysql驱动jar包位置，这里加完pom plugin里面可以不加，相反这里不加pom里需要加上；
数据库连接地址，
entity、mapper、存放位置，
修改 table标签 数据库对应的表明，和要生成实体的表明。

3.

pom 文件添加mysql驱动

 <!--mybatis-generator-->
            <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.5</version>
                <!--    多了这个 加上mysql驱动 generatorComfig.xml 可以不用配置-->
                <dependencies>
                    <dependency>
                        <groupId>mysql</groupId>

                        <version>5.1.21</version>
                    </dependency>
                </dependencies>
                <configuration>
                    <configurationFile>${basedir}/src/main/resources/mybatis-generator/generatorConfig.xml
                    </configurationFile>
                    <overwrite>true</overwrite>
                    <verbose>true</verbose>
                </configuration>
            </plugin>

双击 mybatis-generator:generate 就可以生成了，下面附上完整的pom’
