WebSphere 9 Apache CXF - Bean 验证引发引发：java.lang.ClassNotFoundException：com.ibm.websphere.persistence.PersistenceProviderImpl

Question

我在 IBM 应用服务器版本 9 上部署了一个带有 Hibernate 验证的 Apache CXF 项目

我的休眠设置如下 休眠核心 - 5.2.10.Final org.hibernate.jpa.HibernatePersistenceProvider 作为我的 jpa 提供者

遇到 ClassNotFoundException：com.ibm.websphere.persistence.PersistenceProviderImpl

我在带有 bean 验证的 WAS 8.5 中没有遇到这个问题。

对于 gradle 依赖项

对于控制器

@POST
@Path("/authenticate")
@Consumes(MediaType.APPLICATION_JSON)
public Response authenticateCredentials(@BeanParam BaseRSParams params,
        @Valid @RequestBody AuthenticationParams authenticationParams) throws DirectoryServiceException {

    ldapService = (ILdapService) getService(LDAP_SERVICE_IMPL + params.getVersion());
    ldapService.isUserValid(authenticationParams.getUsername(), authenticationParams.getPassword());

    return Response.ok().build();
}

用于持久化 xml

<persistence-unit name="cifPersistenceUnit" >
    <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
    <properties>
        <property name="hibernate.generate_statistics" value="true"/> 
        <property name="hibernate.show_sql" value="true"/>
        <property name="hibernate.format_sql" value="true"/> 
        <property name="hibernate.temp.use_jdbc_metadata_defaults" value="false"/> 
    </properties>
</persistence-unit>

在 WebSphere Application Server 版本 9.0 中，默认的 JPA 提供程序从 WSJPA/OpenJPA 切换到 EclipseLink。异常堆栈显示您的应用程序正在尝试加载 WSJPA JPA 提供程序类，如果将 EclipseLink 设置为您的 JPA 提供程序（WebSphere 9 中的默认设置），则该提供程序类不可见。

如果您想使用 WSJPA 作为您的 JPA 提供程序，您可以通过转到管理控制台 -> 展开服务器 -> 应用程序服务器 -> 选择您的服务器 -> 展开容器服务 -> 默认 Java 持久性来切换您的默认 JPA 提供程序API 设置 -> 在 JPA 规范下，选择 2.0 并确保默认持久性提供程序设置为“com.ibm.websphere.persistence.PersistenceProviderImpl”
