1、maven引入jar
<dependency> <groupId>com.github.gonglb.tools</groupId> <artifactId>autoupdatetable-mybatis-tkmapper</artifactId> <version>0.0.2</version> </dependency>
2、mybatis开启驼峰转换
<settings> <!--需开启驼峰下划线自动转换 --> <setting name="mapUnderscoreToCamelCase" value="true" /> </settings>
3、SqlSessionFactory配置
xml方式 <!-- 配置SqlSessionFactory对象 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- 注入数据库连接池 --> <property name="dataSource" ref="dataSource" /> <!-- 扫描model包,使用别名,需要增加com.github.gonglb.tools.autoupdatetable.model--> <property name="typeAliasesPackage" value="com.xxxx.xxxx.*.model,com.github.gonglb.tools.autoupdatetable.model" /> <!-- 扫描sql配置文件:mapper接口需要的xml文件 --> <property name="mapperLocations"> <list> <value>classpath*:mapper/*.xml</value><!--需要扫描包内mapper--> <value>classpath*:mapper/*/*.xml</value> </list> </property> <!-- mybatis配置 --> <property name="configLocation" value="classpath:mybatis-settings.xml" /> </bean>
//注解方式 @Bean("sqlSessionFactoryBean") public SqlSessionFactory sqlSessionFactoryBean(DataSource dataSource) throws Exception { SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean(); sqlSessionFactoryBean.setDataSource(dataSource); PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver(); sqlSessionFactoryBean.setConfigLocation(resolver.getResource("classpath:mybatis-setting.xml"));
//扫描保内的mapper Resource[] resources = resolver.getResources("classpath*:mapper/*Mapper.xml"); sqlSessionFactoryBean.setMapperLocations(resources);
//增加扫描工具的model,com.github.gonglb.tools.autoupdatetable.model sqlSessionFactoryBean.setTypeHandlersPackage("com.xxx.xxx.*.model,com.github.gonglb.tools.autoupdatetable.model"); return sqlSessionFactoryBean.getObject(); }
4、MapperScannerConfigurer配置
xml方式 <!-- mapper接口扫描 --> <bean class="com.github.gonglb.tools.autoupdatetable.entrance.AutoTableTKMapperScannerConfigurer"> <property name="basePackage" value="com.xxxx.xxxx.*.mapper" /> <property name="properties"> <value> mappers=tk.mybatis.mapper.common.Mapper,tk.mybatis.mapper.common.special.InsertListMapper </value> </property> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
<!--关键配置--> <!--需要更新表结构的包路径 --> <property name="packs" value="com.xxx.xxx.test.model"/> <!-- 可选参数 create(所有表删除重新创建)、update(更新表)、none(不做操作) --> <property name="tableAuto" value="update"/> </bean>
//注解方式 @Bean public MapperScannerConfigurer getMapperScannerConfigurer() throws Exception { AutoTableTKMapperScannerConfigurer autoTableTKMapperScannerConfigurer = new AutoTableTKMapperScannerConfigurer(); autoTableTKMapperScannerConfigurer.setBasePackage("com.xxx.xxx.*.mapper"); autoTableTKMapperScannerConfigurer.setSqlSessionFactoryBeanName("sqlSessionFactoryBean"); Properties properties = new Properties(); properties.setProperty("mappers", "tk.mybatis.mapper.common.Mapper,tk.mybatis.mapper.common.special.InsertListMapper"); autoTableTKMapperScannerConfigurer.setProperties(properties);
//关键配置 autoTableTKMapperScannerConfigurer.setPacks("com.xxx.xxx.test.model"); autoTableTKMapperScannerConfigurer.setTableAuto("update"); return autoTableTKMapperScannerConfigurer; }
5、model配置方式
import org.apache.ibatis.type.JdbcType; import com.github.gonglb.tools.autoupdatetable.common.ColumnType; @Table(name = "t_test") public class Test{ @Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Column(name = "test_id",nullable = false,unique = false,length = 11,columnDefinition = "主键") @ColumnType(jdbcType = JdbcType.INTEGER) private Integer id;
//不指定name默认自动转换为驼峰下划线模式 @Column(name = "test_name",nullable = true,unique = false,length = 64,columnDefinition = "注释",table="默认值") @ColumnType(jdbcType = JdbcType.VARCHAR) private String name; }
附带自动生成java model 和sql http://47.98.124.10:8088/love-web//html/java/java-model-generate.html
4、注意事项
a、该项目根据 mybatis-enhance-actable-0.0.1 开源项目的思路改编而来
b、该项目会自动删除更新表结构,根据实际情况使用
c、建议单独建立一个模块只负责更新表结构
其他信息mvn clean deploy -P release
