java phoenix 连接hbase

 <dependency>
     <groupId>org.apache.phoenix</groupId>
     <artifactId>phoenix-core</artifactId>
     <version>5.0.-HBase-2.0</version>
 </dependency>

除此之外还需要导入phoenix-5.0.0-HBase-2.0-client.jar

把以下文件拷贝到resources文件夹下

 public class Demo {
     public static void main(String[] args) throws SQLException {
         Connection connection = BaseDB.getConnection();

         String sql = "select * from test";
         PreparedStatement prepareStatement = connection.prepareStatement(sql);
         ResultSet rs = prepareStatement.executeQuery();
         while (rs.next()) {
             System.out.println(rs.getInt());
             System.err.println(rs.getString());
         }

     }
 }
 public class BaseDB {
     public static Connection getConnection() {
         try {
             Class.forName("org.apache.phoenix.jdbc.PhoenixDriver");
             return DriverManager.getConnection("jdbc:phoenix");
         } catch (Exception e) {
             e.printStackTrace();
             return null;
         }
     }
 }
