Spring Boot Actuator DataSourceHealthIndicator不适用于自动配置的DataSource

Question

我在Spring Boot 1.3.6中使用自动配置的DataSource，并且使用Actuator的健康端点。但是，运行状况端点不包括输出中的任何数据库组件。

我application.properties如下：

spring.datasource.url=jdbc:oracle:thin:@localhost:1521:local 
spring.datasource.username=vagrant 
spring.datasource.password=vagrant 
spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver 

endpoints.enabled=false 
endpoints.health.enabled=true 

从/健康端点的输出是：

{"status":"UP","diskSpace":{"status":"UP","total":499863515136,"free":121851781120,"threshold":10485760}} 

我启用跟踪日志记录，它看起来像春天开机自动配置前的卫生指标数据源。下面是来自跟踪日志的摘录（注意时间戳）：

我做得不对，或者这是春天启动的错误吗？有没有办法改变顺序，以便数据源首先被初始化？

Answer 1

我的问题是由从Eclipse运行应用程序引起的。我在src/test/java中也有一个TestApplication类，它排除了DataSourceAutoConfiguration。我从组件扫描中排除TestApplication类（通过excludeFilter,@ComponentScan），并且健康端点按预期工作（即它包括数据库信息）。
