トラクションコントロールシステムは大きく分けて、車輪の回転を検出するセンサーと空転を抑える動作を行うアクチュエータ、センサーからの信号に基づいて計算を行いエンジンやアクチュエータを制御する電子制御ユニット(英: Electronic Control Unit, ECU)で構成されている。車輪の回転を検出するセンサーは各車輪に取り付けられ、駆動輪に取り付けられるものを駆動輪速度センサー、駆動輪ではない車輪に取り付けられるものを従動輪速度センサーと呼び分ける場合がある。車輪の回転に従ってパルス信号を発生するセンサーで、これを基に電子制御ユニットが各輪の回転速度を計算する。電子制御ユニットは、ある駆動輪が他の車輪よりも極端に回転速度が速い場合は空転したと判断し、空転している駆動輪の回転を抑える制御を行う。

I have successfully enabled authorization on MongoDB and I have created an account on the admin database and then I created an account for my database called test. The following connection string to connect to my test database works successfully: mongo --host 192.168.17.52 --port 27017 -u user1 -p password --authenticationDatabase test Only problem I have now is, I cannot execute commands such as: show dbs. I get the following error when I try to do so: "errmsg" : "not authorized on admin to execute command { listDatabases: 1.0, lsid: { id: UUID("a1d5bc0d-bc58-485e-b232-270758a89455") }, $db: "admin...

I tried to upgrade a yummy sandwich made of two test slices (@JsonTest and @JdbcTest in my case, crunchy test code in between) adding spring boot 2.1 flavour to it. But it seems it was not much of a success. I cannot annotate my tests with many @...Test since they are now each bringing their own XxxTestContextBootstrapper. It used to work when they all used same SpringBootTestContextBootstrapper. @RunWith(SpringRunner.class) @JdbcTest @JsonTest public class Test { @Test public void test() { System.out.printn("Hello, World !"); } } The error I get from BootstrapUtils is illegalStateException : Configuration error: found multiple declarations of @BootstrapWith for test class I understand I might be doing something wrong here but is there an easy way I could load both Json and Jdbc contex...
