我已将Actuator添加到现有的Spring Boot（v1.2.2）项目中 . 我的目标是从/ health endpoints 查看数据库信息 . 目前该 endpoints 返回：
{
"status": "UP",
"diskSpace": {
"status": "UP",
"free": 400667607040,
"threshold": 10485760
}
}
我已将这些属性添加到项目的属性文件中：
management.health.db.enabled=true
endpoints.health.enabled=true
endpoints.health.sensitive=false
该项目已经有一个@Configuration类，可以创建一个DataSource bean，如下所示：
@Import({
HealthIndicatorAutoConfiguration.class,
...
@Configuration
public class FooConfig {
@Bean
public DataSource dataSource() {
final HikariConfig hikariConfig = new HikariConfig();
...
return new HikariDataSource(hikariConfig);
}
@EnableAutoConfiguration注释未在项目中的任何位置使用 .
我可以从beans endpoints 看到'dataSource'bean：
{
"bean": "dataSource",
"scope": "singleton",
"type": "com.zaxxer.hikari.HikariDataSource",
"resource": "com.example.FooConfig",
"dependencies": []
},
/ configprops endpoints 包含以下内容：
"healthEndpoint": {
"prefix": "endpoints.health",
"properties": {
"timeToLive": 1000,
"id": "health",
"sensitive": false
}
},
"diskSpaceHealthIndicatorProperties": {
"prefix": "management.health.diskspace",
"properties": {
"path": "/bar/foo/.",
"threshold": 10485760
}
}
但没有dataSource的迹象; ^（
该项目使用的是MySql DB，因此它可以正确响应“SELECT 1”查询 .
我想知道在构建HealthIndicators之后是否正在创建dataSource bean但是到目前为止我的Spring foo已经失败了 .
我宁愿不要写一个自定义的HealthIndicator，但如果必须的话 .
我还将Actuator添加到一个示例项目中，不同之处在于它没有显式创建DataSource bean，而是使用了许多@ Repository标记的接口，这些接口使用H2 DB扩展了CrudRepository，并且它只是工作，例如
{
"status": "UP",
"diskSpace": {
"status": "UP",
"free": 400610689024,
"threshold": 10485760
},
"db": {
"status": "UP",
"database": "H2",
"hello": 1
}
}
正如预期的那样，示例项目的/ configprops endpoints 返回dataSource和diskSpace属性：

感谢一位出色的同事，将以下内容添加到FooConfig解决了我的问题：
即/ health endpoints 现在返回：
