Spring Boot，JPA（Eclipselink）JDNI数据源为JavaConfig

目前，我的Spring Boot应用程序通过Web.xml使用JNDI查找数据源，效果良好：

<resource-ref>
    <res-ref-name>jdbc/DefaultDB</res-ref-name>
    <res-type>javax.sql.DataSource</res-type>
</resource-ref> 

无法以错误开始：

The dependencies of some of the beans in the application context form a cycle

有人能告诉我如何将资源引用添加到我的配置文件中吗？谢谢你的帮助

只要在application.properties中有

spring.datasource.jndi name=java:comp/env/jdbc/DefaultDB

即可配置jndi数据源。首先试试。如果要部署到容器，还需要

web.xml

（或

web fragment.xml

）中的条目。如果您使用的是嵌入式容器，那么不需要JNDI查找，因为这会使事情变得比需要的更复杂。就像Java类中的注释一样。但我不知道我的错。我还尝试了spring.datasource.jndi name=java:comp/env/jdbc/DefaultDB-end-with:name[jdbc/DefaultDB]在这个上下文中没有绑定。找不到[jdbc]。。。我想要部署我的应用程序的平台是SAP HCP（如果这有助于解决问题的话）。我在这篇文章中给出了所有建议，但它仍然不起作用
