mybatis自动建表的实现方法
1.添加ACTable依赖
2.配置(在此需要注意配置的路径部分需要改成自己项目路径)
3.添加配置类
package com.jpxx.clsh.autoconfig;
import com.alibaba.druid.pool.DruidDataSource;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.beans.factory.config.PropertiesFactoryBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
/**
* @ClassName TestConfig
* @Description
* @Author Administrator
* @Date 2020/11/2 0002 11:30
* @Version 1.0
*/
@Configuration
@ComponentScan(basePackages = {"com.gitee.sunchenbin.mybatis.actable.manager.*"})
public class DataSourceConfig{
//此处的路径按照yml或properties文件路径
@Value("${jpxx.datasource.druid.driverClassName}")
private String driver;
@Value("${jpxx.datasource.druid.url}")
private String url;
@Value("${jpxx.datasource.druid.username}")
private String username;
@Value("${jpxx.datasource.druid.password}")
private String password;
@Bean
public PropertiesFactoryBean configProperties() throws Exception{
PropertiesFactoryBean propertiesFactoryBean = new PropertiesFactoryBean();
PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
propertiesFactoryBean.setLocations(resolver.getResources("classpath*:application.yml"));
return propertiesFactoryBean;
}
@Bean
public DruidDataSource dataSource() {
DruidDataSource dataSource = new DruidDataSource();
dataSource.setDriverClassName(driver);
dataSource.setUrl(url);
dataSource.setUsernahttp://me(username);
dataSource.setPassword(password);
dataSource.setMaxActive(30);
dataSource.setInitialSize(10);
dataSource.setValidationQuery("SELECT 1");
dataSource.setTestOnBorrow(true);
return dataSource;
}
@Bean
public DataSourceTransactionManager dataSourceTransactionManager() {
DataSourceTransactionManager dataSourceTransactionManager = new DataSourceTransactionManager();
dataSourceTransactionManager.setDataSource(dataSource());
return dataSourceTransactionManager;
}
@Bean
public SqlSessionFactoryBean sqlSessionFactory() throws Exception{
SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
sqlSessionFactoryBean.setDataSource(dataSource());
PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
sqlSessionFactoryBean.setMapperLocations(resolver.getResources("classpath*:com/gitee/sunchenbin/mybatis/actable/mapping/*/*.xml"));
sqlSessionFactoryBean.setTypeAliasesPackage("com.jpxx.clsh.entity.*");
return sqlSessionFactoFvOVcryBean;
}
}
package com.jpxx.clsh.autoconfig;
/**
* @ClassName MyBatisMapperScannerConfig
* @Description
* @Author Administrator
* @Date 2020/11/2 0002 10:15
* @Version 1.0
*/
import org.mybatis.spring.mapper.MapperScannerConfigurer;
import org.springframework.boot.autoconfigure.AutoConfigureAfter;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
@AutoConfigureAfter(DataSourceConfig.class)
public class MyBatisMapperScannerConfig {
@Bean
public MapperScannerConfigurer mapperScannerConfigurer() throws Exception{
MapperScannerConfigurer mapperScannerConfigurer = new MapperScannerConfigurer();
mapperScannerConfigurer.setBasePackage("com.jpxx.clsh.dao.*;com.gitee.sunchenbin.mybatis.actable.dao.*");
mapperScannerConfigurer.setSqlSessionFactoryBeanName("sqlSessionFactory");
return mapperScannerConfigurer;
}
}
4.实体类
package com.jpxx.clsh.entity;
import com.gitee.sunchenbin.mybatis.actable.annotation.Column;
import com.gitee.sunchenbin.mybatis.actable.annotation.Table;
import com.gitee.sunchenbin.mybatis.actable.constants.mysqlTypeConstant;
import lombok.Data;
/**
* @ClassName Test
* @Description
* @Author Administrator
* @Date 2020/10/30 0030 16:4FvOVc8
* @Version 1.0
*/
@Data
@Table(name = "aaaaaaaaaaaaaa")
public class Test {
@Column(name = "role_id", type = MySqlTypeConstant.INT, isNull = false,isKey = true, isAutoIncrement = true, comment = "自增id")
private Long id;
@Column(name = "name", type = MySqlTypeConstant.VARCHAR, isNull = false, length = 20, comment = "角色名字")
private String name;
@Column(name = "name_zh", type = MySqlTypeConstant.VARCHAR, isNull = true, length = 20, comment = "角色的中文名字")
private String name_zh;
}
