java postgresql csv文件数据导入

1.使用jar驱动自带的CopyManager(我这里使用的是postgresql-9.4.1212.jre7.jar)

public class PGPool {
PGPoolingDataSource source = new PGPoolingDataSource();
public PGPool(){
//PG database server name
source.setServerName("数据库ip");
//PG db port number
source.setPortNumber(端口);
//PG database name
source.setDatabaseName("数据库");
source.setUser("账号");
source.setPassword("密码");
source.setMaxConnections(3);
}

public Connection getConn(){
try{
return source.getConnection();
}catch (Exception e){
e.printStackTrace();
}
return null;
}
}

@Test
public void testCopy() {
   String fileUploadSavePath="C:\\Users\\Administrator.SKY-20170224BTQ\\Desktop\\";
       String savedFileName="bendigongcan(1).csv";
       String tableName = "smartinsight.test_tpm";
   FileInputStream fileInputStream = null;
try {
try {
   PGPool pool = new PGPool();
               CopyManager copyManager = new CopyManager((BaseConnection)pool.getConn().getMetaData().getConnection());
// 程序csv文件路径

fileInputStream = new FileInputStream(fileUploadSavePath+savedFileName);

//如果导入字段与文件中完全相同可以不指定("copy tablename FROM STDIN delimiter ',' csv header encoding 'GBK'")
               String sql = "COPY " + tableName + "(province,city,region,cgi,chinesename,covertype,scenario,iscore,iscounty,istown,isvillage,iscityproper,vendor,flag,earfcnflag,isimportantscenario,admin_area,large_scenario,small_scenario,grid,optiroom,islivearea,ishospital,gaosuname,gaotiename,elevate,iszbcj,isjtsn) FROM STDIN delimiter ',' csv header encoding 'GBK'";//指定分隔符和编码默认是utf-8程序编码
               log.debug(sql);
               copyManager.copyIn(sql, fileInputStream);
           } catch (SQLException | IOException e) {
               e.printStackTrace();
           }
} finally {
if (fileInputStream != null) {
try {
fileInputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}

2.在数据库端命令执行本地文件

copy test_tpm from 'C:\\\\Users\\\\Administrator\\\\Desktop\\sshtest\\\\bendigongcan(1).csv'
delimiter ',' csv header encoding 'GBK';
