我有一个Spring Boot应用程序集成了Hibernate Search来索引我的JPA实体，一切都在本地工作正常。我有以下组件来在应用程序启动时创建索引：
@Component
class SearchIndexBuilder implements ApplicationListener<ApplicationReadyEvent>{
@PersistenceContext
private EntityManager entityManager
void onApplicationEvent(ApplicationReadyEvent event) {
try {
FullTextEntityManager fullTextEntityManager =
Search.getFullTextEntityManager(entityManager);
fullTextEntityManager.createIndexer().startAndWait()
} catch (InterruptedException e) {
System.out.println(
"An error occurred trying to build the search index: " +
e.toString());
}
}
}
但是当我将我的应用程序部署到Pivotal Web Services时，MassIndexer失败并出现以下异常：

我尝试将我的ClearDB计划从Spark升级到Boost，这将DB上的最大连接数从4增加到15，但它没有改变任何内容。
知道我缺少什么吗？
