如果使用maven，

<plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>${mybatis-generator}</version>
                <configuration>
                    <configurationFile>src/main/resources/mybatis-generator/generatorConfig.xml</configurationFile>
                    <verbose>true</verbose>
                    <overwrite>true</overwrite>
                </configuration>
                <executions>
                    <execution>
                        <id>Generate MyBatis Artifacts</id>
                        <goals>
                            <goal>generate</goal>
                        </goals>
                    </execution>
                </executions>
                <dependencies>
                    <dependency>
                        <groupId>org.mybatis.generator</groupId>
                        <artifactId>mybatis-generator-core</artifactId>
                        <version>${mybatis-generator}</version>
                    </dependency>
                </dependencies>
            </plugin>

 另外，生成的mapper.xml中，insert如果有默认值（如自增序列或创建时间等），需要使用insertSelective才能正确插入默认值。
