未启动Elasticsearch时Spring Data Elasticsearch启动报错求助

当机器未启动Elasticsearch服务，且实体类添加@Document(indexName = "t_source_item", createIndex = true)注解时，Spring Boot项目启动失败，抛出连接拒绝的Bean创建异常，具体报错栈如下：

已尝试方案 #

• 使用@Lazy注解，但由于其他Bean依赖ElasticsearchRepository，该方案无法生效，除非调整代码结构增加封装层
• 目前只能在启动Spring Boot应用前手动修改createIndex的值来适配Elasticsearch状态

需求 #

是否有办法避免Spring Data Elasticsearch抛出该错误，或让Spring Boot捕获错误后继续启动？

相关代码 #

@Repository
interface SourceItemESRepository : ElasticsearchRepository<SourceItemDocument, Long>

@Document(indexName = "t_source_item", createIndex = true)
data class SourceItemDocument
