用Maven生成MaBatis的Mapper配置文件和接口

1.在pom.xml文件中加入依赖和插件

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        <pluginManagement>
            <plugins>

                    </configuration>
                    <version>3.3</version>
                </plugin>
                <plugin>
                    <groupId>org.mybatis.generator</groupId>

                    <dependencies>
                        <dependency>
                              <groupId>com.oracle</groupId>
                              <artifactId>ojdbc6</artifactId>
                              <version>11.2.0.4.0</version>
                          </dependency>
                    </dependencies>
                    <configuration>
                         <!--配置文件的路径-->
                         <configurationFile>src/main/resources/generatorConfig.xml</configurationFile> 
                        <overwrite>true</overwrite>
                    </configuration>
                </plugin>
            </plugins>
        </pluginManagement>
    </build>
</project>

2.在项目的classpath中(src/main/resources目录下)新增generatorConfig.xml配置文件

        <!-- 生成DAO的包名和位置 -->

            enableDeleteByExample="false" enableSelectByExample="false"
            selectByExampleQueryId="false"></table>
    </context>
</generatorConfiguration>

3.如果是在eclipse 中,选择pom.xml文件,击右键先择Run AS——>Maven Build… ——>在Goals框中输入:mybatis-generator:generate 

如果在命令行输入Maven命令即可,注意:一定是当前项目目录下运行该命令。

4.刷新当前项目,就可以看到自动生成的代码了,注意代码生成的路径
