Spring Boot Not应用程序不适用于Liberty Server中的JDBC

websphere-liberty spring-boot spring java

afulz29 · 技术社区 · 7 年前

我对弹簧靴还不熟悉。

我正在尝试编写一个RESTAPI,它应该从数据库中获取数据并将其显示给消费者。我不知道如何处理这个问题。

请帮助在Liberty Server上使用JDBC数据源运行应用程序。简单的弹簧靴休息服务工作得非常好。

如果有这么多问题,请原谅我。我想学这个。

这是我的pom文件:

afulz29 7 年前

我已经解决了我所面临的问题。请找出我已经完成的以下步骤。

添加了所有与spring相关的( spring核心、spring Bean、spring jdbc等。 )jar收件人 WEB-INF/lib 文件夹
已添加 @组件 我遗漏了注释,因为应用程序提供了未为@Autowired定义的bean。
已删除' isolationLevel=“事务\u读取\u未提交” '来自 服务器xml .这是较早的设置,因此我 '无法获取JDBC连接异常' 。
添加的功能 “jndi-1.0”、“jdbc-4.1”、“jpa-2.1” 在里面 服务器xml

我不知道这是解决方法还是精确的解决方案,但它确实对我有效。

如果这只是一个解决方法,请纠正我。
