mybatis 自动建表

1. pom 依赖

 <!--mybatis 自动建表-->
        <dependency>
            <groupId>com.gitee.sunchenbin.mybatis.actable</groupId>
            <artifactId>mybatis-enhance-actable</artifactId>
            <version>${mybatis-enhance-actable}</version>
        </dependency>
        <dependency>
            <groupId>commons-lang</groupId>
            <artifactId>commons-lang</artifactId>
            <version>${commons-lang.version}</version>
        </dependency>

2. resources 下新建 application.properties

#自动建表配置
mybatis.table.auto=update
mybatis.model.pack=com.artical.boot.domain
mybatis.database.type=mysql

3. 新建 MybatisTableConfig.java

package com.artical.boot.web.config.mybatis;

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;

/**

 * @Date: 2019/11/7 10:49
 */
@Configuration
@ComponentScan(basePackages = {"com.gitee.sunchenbin.mybatis.actable.manager.*"})
public class MybatisTableConfig {
    @Value("${spring.datasource.druid.driver-class-name}")
    private String driver;

    @Value("${spring.datasource.druid.url}")
    private String url;

    @Value("${spring.datasource.druid.username}")
    private String username;

    @Value("${spring.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.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"));
//实体类的位置
        sqlSessionFactoryBean.setTypeAliasesPackage("com.artical.boot.domain.*");
        return sqlSessionFactoryBean;
    }

}

其中 com.artical.boot.domain.* 为个人的entry包

4. 新建 MyBatisMapperScannerConfig.java

package com.artical.boot.web.config.mybatis;

import org.mybatis.spring.mapper.MapperScannerConfigurer;
import org.springframework.boot.autoconfigure.AutoConfigureAfter;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 * @Author: DaiKuangYin
 * @Date: 2019/11/7 10:50
 */
@Configuration
@AutoConfigureAfter(MybatisTableConfig.class)
public class MyBatisMapperScannerConfig {
    @Bean
    public MapperScannerConfigurer mapperScannerConfigurer() throws Exception{
        MapperScannerConfigurer mapperScannerConfigurer = new MapperScannerConfigurer();
        mapperScannerConfigurer.setBasePackage("com.artical.boot.mapper.*;com.gitee.sunchenbin.mybatis.actable.dao.*");
        mapperScannerConfigurer.setSqlSessionFactoryBeanName("sqlSessionFactory");
        return mapperScannerConfigurer;
    }
}

其中 com.artical.boot.mapper.* 为个人的mapper包

5. 增加 @Table @Column

package com.artical.boot.domain;

import com.gitee.sunchenbin.mybatis.actable.annotation.Column;
import com.gitee.sunchenbin.mybatis.actable.annotation.Table;
import com.gitee.sunchenbin.mybatis.actable.constants.MySqlTypeConstant;

/**
 * @Author: DaiKuangYin
 * @Date: 2019/11/7 10:30
 */
@Table(name = "sys_user")
public class SysUser extends BaseBean{
    @Column(name = "user_id",type = MySqlTypeConstant.INT,length = 20,isKey = true,isAutoIncrement = true)
    private Integer userId;
    @Column(name = "user_account",type = MySqlTypeConstant.VARCHAR,length = 20)
    private String userAccount;//用户账号
    @Column(name = "user_password",type = MySqlTypeConstant.VARCHAR,length = 20)
    private String userPassword;//用户密码
}
