【问题描述】：
我正在尝试将我的 Grails 应用程序从 3.1.10 升级到 3.2.5，以使用新的 GORM 等，但在达到数据库迁移时启动失败。
我明白了：

我已将以下依赖项更新或添加到我的 build.gradle：
buildscript {
...
dependencies {
....
classpath "org.grails.plugins:hibernate5:6.0.4"
classpath 'org.grails.plugins:database-migration:3.0.0'
}
}
dependencies {
...
runtime 'mysql:mysql-connector-java:5.1.40'
compile "org.grails.plugins:hibernate5"
compile "org.hibernate:hibernate-core:5.1.1.Final"
compile "org.hibernate:hibernate-ehcache:5.1.1.Final"
runtime 'org.grails.plugins:database-migration:3.0.0'
compile 'org.liquibase:liquibase-core:3.5.3'
compile 'org.grails.plugins:mongodb'
}
人们之前在这些 Github 问题中看到过 liquibase 错误“PM: liquibase: Can not use class org.grails.plugins.databasemigration.liquibase.GormDatabase as a Liquibase service because it does not have a no-argument constructor”：
https://github.com/grails-plugins/grails-database-migration/issues/81
https://github.com/grails-plugins/grails-database-migration/issues/64#issuecomment-256739113
但对他们来说，这并不是一个重大错误。
当我尝试更新到 Grails 3.2.3 时，我还看到了 liquibase 错误消息，但除此之外一切正常（迁移日志也不可见）。可能问题就出在这里，Grails 3.2.3 使用的是 Spring Boot 1.4.1，而 Grails 3.2.5 使用的是 Spring Boot 1.4.4。
无论如何我迷路了，我希望有人可以帮助我。
编辑：我使用数据库迁移插件来设置我的数据库表，我现在也使用它来更改它。我还在启动时启用了数据库迁移。
EDIT2：问题本身似乎与数据库迁移没有太大关系
我使用多个数据源（application.yml 中的相关部分）：
hibernate:
cache:
queries: false
use_second_level_cache: true
use_query_cache: false
region.factory_class: org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory
dataSources:
dataSource:
pooled: true
jmxExport: true
driverClassName: com.mysql.jdbc.Driver
dialect: org.hibernate.dialect.MySQL5InnoDBDialect
dbCreate: none
properties:
testOnBorrow: true
validationQuery: SELECT 1
myOtherDataSource:
pooled: true
jmxExport: true
driverClassName: net.sourceforge.jtds.jdbc.Driver
dialect: org.hibernate.dialect.SQLServerDialect
dbCreate: none
environments:
development:
dataSources:
dataSource:
url: jdbc:mysql://localhost/my_default_db?useUnicode=yes&characterEncoding=UTF-8&autoReconnect=true
username: my_user
password: my_pass
myOtherDataSource:
driverClassName: com.mysql.jdbc.Driver
dialect: org.hibernate.dialect.MySQL5InnoDBDialect
url: jdbc:mysql://localhost/my_other_db?useUnicode=yes&characterEncoding=UTF-8&autoReconnect=true&failOverReadOnly=false&maxReconnects=10
username: my_user
password: my_pass
当启动时没有数据库迁移时，我也可以启动我的应用程序，但随后出现与 db 相关的不同错误：
ERROR org.hibernate.engine.jdbc.spi.SqlExceptionHelper - PooledConnection has already been closed.
ERROR org.grails.web.errors.GrailsExceptionResolver - SQLException occurred when processing request: [GET] /my-endpoint
