Question

我开始将应用程序从Grails 2.5.5迁移到在Postgres DB上运行的Grails 3.3.8，但是在IntelliJ中启动应用程序时出现错误。以下是详细信息：

错误：

    org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'methodValidationPostProcessor' defined in class path resource [org/springframework/boot/autoconfigure/validation/ValidationAutoConfiguration.class]: Unsatisfied dependency expressed through method 'methodValidationPostProcessor' parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'hibernateDatastoreServiceRegistry': Cannot resolve reference to bean 'hibernateDatastore' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'hibernateDatastore': Bean instantiation via constructor failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.grails.orm.hibernate.HibernateDatastore]: Constructor threw exception; nested exception is java.lang.NoSuchMethodError: org.hibernate.boot.internal.MetadataBuildingContextRootImpl.<init>(Lorg/hibernate/boot/spi/MetadataBuildingOptions;Lorg/hibernate/boot/spi/ClassLoaderAccess;Lorg/hibernate/boot/spi/InFlightMetadataCollector;)V

application.yml：

hibernate:
    cache:
        queries: false
        use_second_level_cache: true
        use_query_cache: false

            username: XXXX
            password: XXXX
            logSql: false

gradle.properties：

grailsVersion=3.3.8
gormVersion=6.1.10.RELEASE
gradleWrapperVersion=3.5

我遵循了grails迁移指南，并给出了正确的依赖关系和Postgres方言。我还在外部库中看到了postgresql-9.0-801.jdbc4.jar，因此无法找出错误原因。

谢谢

Answer 1

您使用的jdbc驱动程序来自2010年-使用更新的驱动程序，例如https://mvnrepository.com/artifact/org.postgresql/postgresql/42.2.5

GORM 6.1最多支持Hibernate 5.2-您正在使用Hibernate 5.3。

Answer 2

按照@erichelgeson的建议，我升级了jdbc驱动程序，但还必须进行其他一些更改，例如添加dict1 = {} def createCarDictionary(datafile): for line in datafile.splitlines(): line = line.replace(',', '') key, value, value2 = map(str.strip, line.split('|')) dict1[key] = [int(value), int(value2)] return dict1 datafile = open('data.txt', 'r').read() createCarDictionary(datafile) print(dict1)并将org.jadira.usertype:usertype.core:5.0.0.GA更改为region.factory_class才能获得它完全正常工作。

build.gradle：

org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory

application.yml：

buildscript {
    repositories {
        mavenLocal()
        mavenCentral()
        maven { url "https://repo.grails.org/grails/core" }

    runtime "org.postgresql:postgresql:42.2.5" // POSTGRES
}

无法使用Postgres DB启动Grails 3.3.8应用程序
