當(dāng)我在maven test本地運(yùn)行時通過。但是，當(dāng)我在CI服務(wù)器上運(yùn)行該錯誤時，出現(xiàn)此錯誤。Error MessageCould not open JPA EntityManager for transaction; nested exception is org.hibernate.exception.JDBCConnectionException: Unable to acquire JDBC ConnectionStacktraceorg.springframework.transaction.CannotCreateTransactionException: Could not open JPA EntityManager for transaction; nested exception is org.hibernate.exception.JDBCConnectionException: Unable to acquire JDBC ConnectionCaused by: org.hibernate.exception.JDBCConnectionException: Unable to acquire JDBC ConnectionCaused by: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failureThe last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.Caused by: java.net.UnknownHostException: mysql運(yùn)行本地測試時，它們都通過了測試，并使用IntelliJ IDEA提供的maven測試默認(rèn)設(shè)置。由于該錯誤抱怨數(shù)據(jù)庫連接問題，因此我通過Jenkins Audit檢查了Database Plugin。連接成功！我的連接參數(shù)application.properties也與此對應(yīng)spring.datasource.url=jdbc:mysql://mysql:3306/database?useLegacyDatetimeCode=false&serverTimezone=Asia/Shanghaispring.datasource.username=rootspring.datasource.password=passwordspring.datasource.maxActive=5URL中的MySQL是MySQL docker容器名稱。如果用錯誤消息中的localhost或?qū)Ｓ肐P進(jìn)行更改docker container inspect mysql是相同的，而后兩行中的Stacktrace則有所不同。對于本地主機(jī)The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.Caused by: java.net.ConnectException: Connection refused (Connection refused)用于私有IPThe last packet sent successfully to the server was 0 milliseconds ago.

Jenkins插件成功連接到MySQL3.從Jenkins運(yùn)行時，集成測試失敗。4.本地測試環(huán)境為WIN10 64bit；Jenkins在Ubuntu 16.04 64位服務(wù)器上的docker容器中運(yùn)行，MySQL 5.7容器連接到同一網(wǎng)橋網(wǎng)絡(luò)。
