今天完成的事情：
服务器上用jar包插入一百万条数据
复习一下mvn命令，使用mvn命令运行了下jar包
mvn test 运行测试
mvn site 产生site
mvn package 打包
mvn install 在本地Repository中安装jar：
mvn clean 清除产生的项目：
mvn eclipse:eclipse 生成eclipse项目：
mvn idea:idea 生成idea项目：
mvn -Dtest package 组合使用goal命令，如只打包不测试：
mvn test-compile 编译测试的内容：
mvn jar:jar 只打jar包:
package mybatis;
import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;
import java.io.IOException;
import java.io.InputStream;
public class MapperTest {
private static SqlSessionFactory sqlSessionFactory;
public static void main(String[] args) throws IOException {
long start=System.currentTimeMillis();
String resource = "sqlMapConfig.xml"; //mybatis配置文件
//得到配置文件的流
InputStream inputStream = Resources.getResourceAsStream(resource);
//创建会话工厂SqlSessionFactory,要传入mybaits的配置文件的流
sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream);
SqlSession sqlSession = sqlSessionFactory.openSession();
User user=new User("韩","梁家键","前端工程师");
int aa = Integer.valueOf(args[0]);
for (int s=0;s<=aa;s++){
// User user=new User("韩");
sqlSession.insert("mybatis.UserMapper.insertUser",user);
sqlSession.commit();
// long a = user.getId();
}
sqlSession.close();
long end=System.currentTimeMillis();
long a = user.getId();
System.out.println(a);
System.out.println("程序运行时间： "+(end-start)/1000+"S");
}
}

明天计划的事情：
任务一深度思考
遇到的问题：
输入中文字符报错
本地能运行，但是jar包无法运行
原因一，大小写的问题
原因二：依赖的缺失
这时候需要正确的包
<plugin>

<configuration>
<appendAssemblyId>false</appendAssemblyId>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>

还有一种路径配置方法

<filtering>true</filtering>

<include>**/*.xml</include>
