1 <dependency>
2     <groupId>org.apache.phoenix</groupId>
3     <artifactId>phoenix-core</artifactId>
4     <version>5.0.0-HBase-2.0</version>
5 </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

 1 public class Demo {
 2     public static void main(String[] args) throws SQLException {
 3         Connection connection = BaseDB.getConnection();
 4 
 5         String sql = "select * from test";
 6         PreparedStatement prepareStatement = connection.prepareStatement(sql);
 7         ResultSet rs = prepareStatement.executeQuery();
 8         while (rs.next()) {
 9             System.out.println(rs.getInt(1));
10             System.err.println(rs.getString(2));
11         }
12 
13     }
14 }
15 public class BaseDB {
16     public static Connection getConnection() {
17         try {
18             Class.forName("org.apache.phoenix.jdbc.PhoenixDriver");
19             return DriverManager.getConnection("jdbc:phoenix");
20         } catch (Exception e) {
21             e.printStackTrace();
22             return null;
23         }
24     }
25 }
