我有一个集成 Hibernate Search 的 Spring Boot 应用程序来索引我的 JPA 实体，并且在本地一切正常。我有以下组件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，当我将应用程序部署到 Pivotal Web 服务时，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，但它没有改变任何东西。
知道我缺少什么吗？
