mybatis 自动更新表结构 ，兼容通用tkmapper

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
