如何在服务器模式下运行H2数据库？
提问于 2012-02-17 03:53:30
我需要从我的应用程序中以服务器模式启动H2数据库。我已经尝试过以下代码：
server = Server.createTcpServer().start();以下是该连接的属性：
javabase.jdbc.url = jdbc:h2:tcp://localhost:9092/nio:~/source/db/database/db;AUTO_SERVER=TRUE
javabase.jdbc.driver = org.h2.Driver
javabase.jdbc.username = sa
javabase.jdbc.password =当我运行这个程序时，我得到了以下错误：
client.db.exception.DAOException: org.h2.jdbc.JdbcSQLException: Database may be already in use: "Locked by another process". Possible solutions: close all other connection(s); use the server mode [90020-164]

在命令行中，
java -jar h2-1.3.160.jar -webAllowOthers -tcpAllowOthers这将在服务器模式下启动h2数据库：
Web Console server running at http://A.B.C.D:8082 (others can connect)
TCP server running at tcp://A.B.C.D:9092 (others can connect)
PG server running at pg://A.B.C.D:5435 (only local connections)打开浏览器以获得管理员GUI

关闭所有使用H2的应用程序(web控制台等)，然后在h2控制台和java程序中将AUTO_SERVER=TRUE添加到该位置的末尾(您已经这样做了)

还有一种方法。您可以定义@Configuration bean，例如：‘@Configuration公共类H2Configuration {
@Bean
public void startTCPServer(){
try {
Server h2Server = Server.createTcpServer().start();
if (h2Server.isRunning(true)) {
System.out.println(h2Server.getStatus());
} else {
throw new RuntimeException("Could not start H2 server.");
}
} catch (SQLException e) {
throw new RuntimeException("Failed to start H2 server: ", e);
}
}}‘
