我尝试使用“TRACE_LEVEL_FILE = 4”上的服务器/ TCP在H2中，“TRACE_LEVEL_FILE = 4”仅适用于本地/嵌入式数据库吗？
DriverManager.getConnection("jdbc:h2:tcp://localhost/" + f.toURI() +";TRACE_LEVEL_FILE=4;", "sa", "");
和日志级别设置为与
java.util.logging.Logger h2database = java.util.logging.Logger.getLogger("h2database");
h2database.setLevel(Level.WARNING);
和所有我得到的是在scan123db.trace此消息警告。 db

我想知道为什么？
看起来服务器端缺少类org.slf4j.LoggerFactory。但“TRACE_LEVEL_FILE = 4”选项目前不影响客户端/服务器案例的客户端。 –
H2服务器是通过h2.bat启动的，这些错误在我运行客户端并且由客户端报告后开始显示。 – Alex
