我正在从Grails 2.5.6迁移我的应用程序 - ＆gt; 3.3.5。到目前为止，我只移动了我的域类以及域类中所需的一些服务。应用程序编译然后它似乎尝试启动但失败。这是我收到的错误：

正如你所看到的，Spring正在抛出一个不满意的依赖异常。我从application.yml的连接在下面，似乎遵循正确的格式。

我错过了依赖吗？什么会导致这个错误？
答案 0 :(得分：5)
您是否已选中此Upgrading from Grails 2.x
不需要许多回购，因此请使用下面的代码块进行更改：
repositories {
mavenLocal()
maven { url "https://repo.grails.org/grails/core" }
}
如果使用的是最新版本的MySQL，则驱动程序类和依赖项将更改：
dependencies {
runtime "mysql:mysql-connector-java:6.0.6"
}
和application.yml应该包含：
production:
dataSource:
dbCreate: update
pooled: true
url: jdbc:mysql://localhost:3306/yourDB?autoReconnect=true&useSSL=false&useUnicode=true
driverClassName: com.mysql.cj.jdbc.Driver
dialect: org.hibernate.dialect.MySQL5InnoDBDialect
我有以下休眠配置：
hibernate:
cache:
use_second_level_cache: true
provider_class: net.sf.ehcache.hibernate.EhCacheProvider
region:
factory_class: org.hibernate.cache.ehcache.EhCacheRegionFactory
如果您正在使用较低版本的MySql，请根据其使用MySQL依赖项。您可以检查所有MySQL依赖项版本here
处理'命令'/Library/Java/JavaVirtualMachines/jdk1.8.0_161.jdk/Contents/Home/bin/java''的退出值非零完成
为此，请尝试增加堆空间。通常在启动应用程序时，它会占用大量内存。
您是否检查了最后一条错误消息：
原因：java.lang.NullPointerException：null 在org.grails.orm.hibernate.cfg.GrailsDomainBinder.bindManyToOneValues（GrailsDomainBinder.java:2473）
我认为您还需要检查域类及其关系。
希望这对您有帮助
答案 1 :(得分：1)
尝试使用
{
...
compile('org.springframework.boot:spring-boot-autoconfigure') { excludes "hibernate-validator"}
}
答案 2 :(得分：0)
application.yml 中错过了hibernate配置。例如：
hibernate:
cache:
queries: false
use_second_level_cache: true
use_query_cache: false
region.factory_class: 'org.hibernate.cache.ehcache.EhCacheRegionFactory'
