#ssm项目通过控制台启动

本文介绍了一个使用Spring框架整合MyBatis的示例，展示了如何通过Spring的依赖注入和事务管理特性来操作数据库。代码中包含了读取配置、创建数据源、设置SqlSessionFactory、扫描DAO接口以及进行数据库操作的过程。

import cn.jpp.model.*;
import cn.jpp.service.impl.AllService;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.stereotype.Component;
import org.springframework.web.servlet.ModelAndView;

import java.util.List;

@Component
public class main {
    //读取console.xml
    private static ApplicationContext applicationContext = new ClassPathXmlApplicationContext("console.xml");
   //获取服务    
private static AllService allService=(AllService)applicationContext.getBean("allService");

    public static void main(String[] args) {
        //StInstance
        List<StInstance2> user = allService.getList();
//        allService.insert(user);
        //XtInstance
        List<OldXtInstance> oldXtInstanceList = allService.getXtInstance();
//        allService.insertXtInstance(oldXtInstanceList);
        //UT_GW_ARCHIVE_INCEPT
        List<oldAchiveIncept> oldAchiveIncept = allService.getAchiveIncept();
//        allService.insertAchiveIncept(oldAchiveIncept);
        //ST_DYNAMIC_RESOURCE
        List<oldStDynamicResource> oldStDynamicResourceList = allService.getResourceList();
//        allService.insertStDynamicResource(oldStDynamicResourceList);
        //st_work_item_hist
        List<oldStWorkItemHist> oldStWorkItemHistList = allService.getOldStWorkItemHist();
//        allService.insertWorkItemHistList(oldStWorkItemHistList);
        //Ut_file
        List<oldFile> oldFiles = allService.getOldFiles();
    }

}
