Question

我使用spring-boot + gorm + sqlserver数据源创建一个小应用程序（非常类似于Tim Yates＆＃39; https://github.com/timyates/data-gorm-mysql/）。

我的数据源属性位于application.properties中：

dbDriverClassName=...
dbUsername=...

我的build.gradle有

compile("org.springframework.boot:spring-boot-starter-web")
compile("org.grails:gorm-hibernate4-spring-boot:1.0.0.RC1")

工作正常。但是当我将执行器添加到build.gradle时，我会收到错误：

compile("org.springframework.boot:spring-boot-starter-actuator")

我错过了什么？谢谢！

Answer 1

解决方案：

我将build.gradle行从RC1更改为RC2并且现在没有错误（测试切换回RC1以确认错误，然后返回RC2 - 没有错误）。

compile("org.grails:gorm-hibernate4-spring-boot:1.0.0.RC2")

@Dave，谢谢你的提示。但是为什么你说没有理由使用自定义DataSource，有更好的方法吗？

我应该看一下repo.spring.io的最新版本，但堆栈跟踪让我觉得这是执行器环境的一个问题。

外部化数据源属性和使用执行器时的spring-boot属性异常
