转载：CLickHouse出现端口异常问题

执行一段代码，然后报错如下Port 9000 is for clickhouse-client program

详细的报错如下

java.lang.RuntimeException: ru.yandex.clickhouse.except.ClickHouseUnknownException: ClickHouse exception, code: 1002, host: 10.3.1.59, port: 9000; Port 9000 is for clickhouse-client program. You must use port 8123 for HTTP.

详细的代码如下

public void nativeClient3() throws Exception {
        Class.forName("com.github.housepower.jdbc.ClickHouseDriver");
        Connection connection = DriverManager.getConnection("jdbc:clickhouse://localhost:9000");

        PreparedStatement pstmt = connection.prepareStatement("insert into lcc.t_city values(?, ?, ?,?)");

        // insert 10 records
        for (int i = 0; i < 10; i++) {
            pstmt.setString(1, "panda_" + (i + 1));
            pstmt.setString(2, "panda_" + (i + 1));
            pstmt.setDate(2, new Date(System.currentTimeMillis()));
            pstmt.setInt(3, 18);
            pstmt.addBatch();
        }
        pstmt.executeBatch();
    }

后来测试发现，同时引入了两个jar包，一个官方jar包，一个非官方jar包

<dependency>
            <groupId>com.github.housepower</groupId>
            <artifactId>clickhouse-native-jdbc</artifactId>
            <version>1.7-stable</version>
        </dependency>
        <dependency>
            <groupId>ru.yandex.clickhouse</groupId>
            <artifactId>clickhouse-jdbc</artifactId>
            <version>0.2</version>
        </dependency>

官方jar包默认是8123端口，而第三方jar包（clickhouse-native-jdbc）默认端口是9000，如果同时引入两个jar包，虽然自己指定

Class.forName("com.github.housepower.jdbc.ClickHouseDriver")

为第三方jar包，实际执行中，使用官方端口.

2.源代码

2.1 官方

官方第三方jar包是继承了

public class ClickHouseDriver implements Driver

2.2 非官方

官方jar包是 直接继承 Driver类

public class ClickHouseDriver implements Driver {

    static {
        try {
            DriverManager.registerDriver(new ClickHouseDriver());
        } catch (SQLException e) {
            throw new RuntimeException(e);
        }
    }

3.解决方案

解决方案，只引入一个jar包，如果是官方的jar包就使用8123端口，如果是第三方是 9000端口

public class ClickHouseTest3 {
 
 
    public static void main(String[] args)  {
        System.out.println("test click house");
        try {
            Class.forName("com.github.housepower.jdbc.ClickHouseDriver");//第三方jar包
// Class.forName("ru.yandex.clickhouse.ClickHouseDriver");//官方
 
            //如果官方jar包引入,则下面不能执行，如果包官方jar包去掉，则可以执行
            Connection connection = DriverManager.getConnection("jdbc:clickhouse://127.0.0.1:9000");//第三方
            Statement statement = connection.createStatement();
            ResultSet rs = statement.executeQuery("select count(*) from test");
            if (rs.next()) {
                int count = rs.getInt(1);
                System.out.println(count);
            }
        }catch (Exception e){
            e.printStackTrace();
        }
    }
 
}
