無法在Grails中創建池問題的初始連接

Question

我的高級創建了遠程oracle JDBC，我必須連接到特定的WiFi才能訪問數據庫方案。雖然配置我DataSource.groovy中的如下：

dataSource { 
pooled = true 
jmxExport = true 
driverClassName = "oracle.jdbc.OracleDriver" 
username = "test" 
password = "pass"} 

hibernate { 
cache.use_second_level_cache = true 
cache.use_query_cache = false 
} 

environments { 
development { 
    dataSource { 
     dbCreate = "create-drop" // one of 'create', 'create-drop', 'update', 'validate', '' 
     url = "jdbc:oracle:thin:@10.42.0.1:1521:xe" 
     username = "test" 
     password = "pass" 
     driverClassName = "oracle.jdbc.OracleDriver" 
     dialect = imocha.hibernate.dialect.Oracle11gDialect 
    } 
} 
test { 
    dataSource { 
     dbCreate = "update" 
     url = "jdbc:oracle:thin:@10.42.0.1:1521:xe" 
     username = "test" 
     password = "pass" 
     driverClassName = "oracle.jdbc.OracleDriver" 
     dialect = imocha.hibernate.dialect.Oracle11gDialect 
    } 
} 
production { 
    dataSource { 
     dbCreate = "update" 
     url = "jdbc:oracle:thin:@10.42.0.1:1521:xe" 
     username = "test" 
     password = "pass" 
     driverClassName = "oracle.jdbc.OracleDriver" 
     dialect = imocha.hibernate.dialect.Oracle11gDialect 
     properties { 
      // See http://grails.org/doc/latest/guide/conf.html#dataSource for documentation 
      jmxEnabled = true 
      initialSize = 5 
      maxActive = 50 
      minIdle = 5 
      maxIdle = 25 
      maxWait = 10000 
      maxAge = 10 * 60000 
      timeBetweenEvictionRunsMillis = 5000 
      minEvictableIdleTimeMillis = 60000 
      validationQuery = "SELECT 1" 
      validationQueryTimeout = 3 
      validationInterval = 15000 
      testOnBorrow = true 
      testWhileIdle = true 
      testOnReturn = false 
      jdbcInterceptors = "ConnectionState" 
      defaultTransactionIsolation = java.sql.Connection.TRANSACTION_READ_COMMITTED 
     } 
    } 
} 

但它仍然顯示無法創建Grails中的池問題的初步連接。我已經清除了我的Grails中的代理（我工作的地方需要代理連接到WiFi），因爲我的高級代理會影響Grails中的連接。我想知道我無法連接到遠程數據庫的原因是什麼。

我附上下面的錯誤日誌：

PS我使用的Grails 2

Answer 1

你得到一個ClassNotFoundException：oracle.jdbc.driver.OracleDriver

是您ojdbcXX.jar上的應用程序的類路徑？

根據Oracle版本你使用（好像是11），你可能只需要驅動程序包的名字從改變：

driverClassName = "oracle.jdbc.driver.OracleDriver" 

要

driverClassName: 'oracle.jdbc.OracleDriver'
