windows下创建h2集群，及java集成详细步骤

Posted 2020-10-02 游浪踏

1.下载h2包，解压

2.cmd操作，进入bin目录

3.创建两个目录

 

4.建立集群

输入以下命令(需要进入h2的bin目录)

java -cp "h2-1.4.195.jar;%H2DRIVERS%;%CLASSPATH%" org.h2.tools.Server -tcpAllowOthers -tcpPort 9101 -webAllowOthers -webPort 8081 -baseDir D:\\database\\h2Cluter\\h2_1

java -cp "h2-1.4.195.jar;%H2DRIVERS%;%CLASSPATH%" org.h2.tools.Server -tcpAllowOthers -tcpPort 9102 -webAllowOthers -webPort 8082 -baseDir D:\\database\\h2Cluter\\h2_2

java -cp h2-1.4.195.jar org.h2.tools.CreateCluster -urlSource "jdbc:h2:tcp://127.0.0.1:9101/testCluster" -urlTarget "jdbc:h2:tcp://127.0.0.1:9102/testCluster" -user "sa" -serverList "127.0.0.1:9101,127.0.0.1:9102"

 5.浏览器查看集群

http://192.168.30.50:8081

或者http://192.168.30.50:8082

6.java连接

导入jar包

public static void main(String[] args) throws ClassNotFoundException, SQLException {
        String sourceURL = "jdbc:h2:tcp://localhost:9101,localhost:9102/testCluster";// H2DB mem
                                                                    // mode
        String user = "sa";
        String key = "";
        Class.forName("org.h2.Driver");// HSQLDB Driver
        Connection conn = DriverManager.getConnection(sourceURL, user, key);// 把驱动放入连接
        Statement stmt = conn.createStatement();
        stmt.execute("CREATE TABLE mytable(name VARCHAR(100),sex VARCHAR(10))");
        // String sql = "SELECT VALUE FROM INFORMATION_SCHEMA.SETTINGS WHERE
        // NAME=\'CLUSTER\'";
        stmt.executeUpdate("INSERT INTO mytable VALUES(\'Steven Stander\',\'male\')");
        stmt.executeUpdate("INSERT INTO mytable VALUES(\'Elizabeth Eames\',\'female\')");
        stmt.executeUpdate("DELETE FROM mytable WHERE sex=\'male\'");
        stmt.close();
        conn.close();
    }
