【问题描述】：

我很难弄清楚为什么 Grails 无法运行我创建的插件。这是我的环境：

Grails 版本：3.2.6
Groovy 版本：2.4.7
JVM 版本：1.8.0_91

这些是我的步骤：

我创建了插件：
```
grails create-plugin bioprofile
```
我添加 Spring Security 核心插件，将此行添加到 build.gradle:
```
compile 'org.grails.plugins:spring-security-core:3.1.1'
```
我运行s2-quickstart 命令来设置User、Role 和UserRole：
```
grails s2-quickstart cscie56.ps5 User Role
```
我修改了User 域类以包含一些新字段

创建了一些其他领域类

grails create-domain-class cscie56.ps5.BlogEntry
grails create-domain-class cscie56.ps5.Comment

我生成了控制器等...

grails generate-all BlogEntry
grails generate-all User
grails generate-all Role
grails generate-all UserRole

我在BootStrap.groovy文件中添加了如下初始化：

package bioprofile

import cscie56.ps5.Role
import cscie56.ps5.User
import cscie56.ps5.UserRole

class BootStrap {

    def init = { servletContext ->
        environments {
            development {
                setupData()
                setupUsersAndRoles()
                println "Developement execution"
            }
            test {
                setupData()
                setupUsersAndRoles()
                println "Test execution"
            }
            production {
                // do nothing
                println "Production execution"
            }
        }
    }

    def destroy = {
    }

    def setupUsersAndRoles() {
        User admin = new User(username: 'admin', password: 'password')
        admin.save(flush: true)
        User user = new User(username: 'user', password: 'user')
        user.save(flsuh:true)

        Role adminRole = new Role(authority: Role.ROLE_ADMIN)
        adminRole.save(flush:true)

        Role userRole = new Role(authority: Role.ROLE_USER)
        userRole.save(flush:true)

        UserRole.create(admin, adminRole)
        UserRole.create(admin, userRole)
        UserRole.create(user, userRole)
    }

    def setupData() {

    }
}

当我使用 grails run-app 运行应用程序时，我收到了这个乏味的错误：

Running application...
objc[84720]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.8.0_91.jdk/Contents/Home/bin/java and /Library/Java/JavaVirtualMachines/jdk1.8.0_91.jdk/Contents/Home/jre/lib/libinstrument.dylib. One of the two will be used. Which one is undefined.

我试着跑了

grails clean
grails clean --refresh-dependencies
grails compile

但结果相同。

有人遇到过这个问题或知道根本原因是什么？

【问题讨论】：

问题（我仍然不明白根本原因）似乎与以下指令有关： admin.save(flush: true) adminRole.save(flush:true) userRole.save( flush:true) ...所以某些东西可能没有正确初始化以允许持久性发生？
.withTransaction {
@vahid 你能提供更多细节吗？
这是一个重复的主题，您是否对该词进行了任何搜索。因为如果你确实很确定会返回很多结果。 grails 中的服务在 grails 3 上的任何其他地方都是自动事务的，您需要将事务包装在它周围。
类似的主题表明缺少休眠配置，但据我所知，在我的休眠 5 情况下，生成的配置样板看起来不错。这些是没有服务的域类。你能指出一个正确的例子，应该在哪里使用 .withTransaction 以及它应该实际包装什么？

【解决方案1】：

如果其他人遇到同样的问题，这对我有用。这似乎是一个休眠依赖问题。不明显，而且很可能是在多个文件中生成样板文件的任何细微错误（从来不是“我会为你做这一切”框架的忠实粉丝）。在我的特定情况下（这可能特定于我的环境），通过在 build.gradle 文件中用 hibernate4 替换生成的 hibernate5 依赖项，上面的错误就消失了。这就是我现在所拥有的（删除了 hibernate5 的东西）：

classpath "org.grails.plugins:hibernate4:5.0.10"

compile "org.grails.plugins:hibernate4"
compile "org.hibernate:hibernate-core:4.3.10.Final"
compile "org.hibernate:hibernate-ehcache:4.3.10.Final"

.withTransaction { hack 似乎对解决这个问题没有任何作用。
