springboot+mybatis自动创建表

2.添加依赖

本人pom.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            </plugin>
        </plugins>
    </build>
</project>

2.创建application.yml文件

3.配置application.properties

 4创建实体类

@Table(name = "user")
public class Test extends BaseModel{
 
    private static final long serialVersionUID = 5199200306752426433L;
 
    @Column(name = "id",type = MySqlTypeConstant.INT,length = 11,isKey = true,isAutoIncrement = true)
    private Integer id;
 
    @Column(name = "name",type = MySqlTypeConstant.VARCHAR,length = 111)
    private String  name;
 
   
    //省略Setter、Getter
 
}

5.创建MyBatisMapperScannerConfig和TestConfig的java类

@Configuration
@ComponentScan(basePackages = {"com.gitee.sunchenbin.mybatis.actable.manager.*"})
public class TestConfig {
 
    @Value("${spring.datasource.driver-class-name}")
    private String driver;
 
    @Value("${spring.datasource.url}")
    private String url;
 
    @Value("${spring.datasource.username}")
    private String username;
 
    @Value("${spring.datasource.password}")
    private String password;
 
    @Bean
    public PropertiesFactoryBean configProperties() throws Exception{
        PropertiesFactoryBean propertiesFactoryBean = new PropertiesFactoryBean();
        PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
        propertiesFactoryBean.setLocations(resolver.getResources("classpath*:application.properties"));
        return propertiesFactoryBean;
    }
 
    @Bean
    public DruidDataSource dataSource() {
        DruidDataSource dataSource = new DruidDataSource();
        dataSource.setDriverClassName(driver);
        dataSource.setUrl(url);
        dataSource.setUsername(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.example.entity.*");
        return sqlSessionFactoryBean;
    }
 
}

@Configuration
@AutoConfigureAfter(TestConfig.class)
public class MyBatisMapperScannerConfig {
 
    @Bean
    public MapperScannerConfigurer mapperScannerConfigurer() throws Exception{
        MapperScannerConfigurer mapperScannerConfigurer = new MapperScannerConfigurer();
        mapperScannerConfigurer.setBasePackage("com.example.mapper.*;com.gitee.sunchenbin.mybatis.actable.dao.*");
        mapperScannerConfigurer.setSqlSessionFactoryBeanName("sqlSessionFactory");
        return mapperScannerConfigurer;
    }
 
}

在配置文件中的，com.example.entity.*需要换成自己项目中的实体层目录，com.example.mapper.*需要换成自己项目中的mapper目录
