使用连接池，你只需添加
validationQuery=”SELECT CURRENT DATE FROM sysibm.sysdummy1”我的context.xml ？如果是的话，你的服务器可能会消除空闲的连接（或重新启动数据库服务器）。您是否为连接池配置了验证查询，以便在将连接提供给您的webapp之前检查该查询？如果没有，那就这样做。 – Andreas'<资源 \t \t名称= “JDBC/DB2_IBS_BSV” \t \t AUTH = “容器” \t \t类型= “javax.sql.DataSource中” \t \t用户名= “*******” \t \t密码= “******” \t \t driverClassName = “com.ibm.as400.access.AS400JDBCDriver” \t \t URL = “JDBC：AS400：// SV4013CB /” \t \t maxActive = “50” \t \t maxIdle =“30” />' –
