寫入mysql的grails bootstrap錯誤

Question

我在一個簡單的應用程序中使用spring安全性。連接到amazon RDS實例時，該應用在本地運行良好。當我上傳我的應用程序彈性魔豆創建一個角色的失敗，在引導：

def init = { servletContext -> 

    println log.name 

    log.debug("hello 1") 
    def adminRole = new Role(authority: 'ROLE_ADMIN') 
    log.debug("hello 2") 
    if (!adminRole.save(flush: true, failOnError: true)) { 
     log.debug("hello 3") 
     adminRole.errors.each { 
      println it 
      log.error(it) 
     } 
    }

如果它是一個數據庫連接的問題 - 它可能是 - 我還以爲錯誤會一直「哎， '連接到數據庫'。不是無法找到Role.save（）的非描述性錯誤。

編輯： 全部引導：

import com.nrfa.Role 
import com.nrfa.User 
import com.nrfa.UserRole 

class BootStrap { 
    def springSecurityService 

    def init = { servletContext -> 

     println log.name 

     log.debug("hello 1") 
     def adminRole = new Role(authority: 'ROLE_ADMIN') 
     log.debug("hello 2") 
     if (!adminRole.save(flush: true, failOnError: true)) { 
      log.debug("hello 3") 
      adminRole.errors.each { 
       println it 
       log.error(it) 
      } 
     } 
     log.debug("hello 4") 
     def userRole = new Role(authority: 'ROLE_USER').save(flush: true, failOnError: true) 

     def testUser = new User(username: 'me', password: 'password') 
     testUser.save(flush: true, failOnError: true) 

     UserRole.create testUser, userRole, true 

     assert User.count() == 1 
     assert Role.count() == 2 
     assert UserRole.count() == 1 


    } 

    def destroy = { 
    } 
} 

編輯：包括BuildConfig.Groovy：

dependencies { 
    // specify dependencies here under either 'build', 'compile', 'runtime', 'test' or 'provided' scopes e.g. 

    //runtime 'mysql:mysql-connector-java:5.1.27' 

    runtime 'org.slf4j:slf4j-api:1.7.5' 
} 

plugins { 
    build ":hibernate:$grailsVersion" 
    runtime ":jquery:1.8.3" 
    runtime ":resources:1.2" 
    runtime ":mysql-connectorj:5.1.22.1" 
    compile ':spring-security-core:2.0-RC2' 


    // Uncomment these (or add new ones) to enable additional resources capabilities 
    //runtime ":zipped-resources:1.0" 
    //runtime ":cached-resources:1.0" 
    //runtime ":yui-minify-resources:0.1.5" 

    build ":tomcat:$grailsVersion" 

    build ":database-migration:1.3.2" 

    compile ':cache:1.0.1' 

//運行 「的：mysql-的ConnectorJ：5.1.22.1」 }

Answer 1

該錯誤通常表明hibernate插件沒有被安裝或工作。你能看到遠程服務器上的擴展戰爭嗎？我不熟悉豆杆本身的運作，所以也許有些東西在那裏發生衝突。

Answer 2

在依賴項中添加「runtime'mysql：mysql-connector-java：5.1.27'」並將其從插件中刪除？
