mybatis自动建表的实现方法

1.添加actable依赖

   <!--mybatis-plus自动建表-->
    <dependency>
      <groupid>com.gitee.sunchenbin.mybatis.actable</groupid>
      <artifactid>mybatis-enhance-actable</artifactid>
      <version>1.1.1.release</version>
    </dependency>

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)

   <!--mybatis-plus自动建表-->
    <dependency>
      <groupid>com.gitee.sunchenbin.mybatis.actable</groupid>
      <artifactid>mybatis-enhance-actable</artifactid>
      <version>1.1.1.release</version>
    </dependency>

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.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.jpxx.clsh.entity.*");
    return sqlsessionfactorybean;
  }

}

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 16:48
 * @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;
}
