我使用liquibase和maven。當我通過maven執行我的sql腳本時，我多次得到No operations allowed after connection closed錯誤。 奇怪的部分是，有時它的工作，很多時候我得到這個錯誤。通常它在我執行3-5次之後起作用。當與MySQL一起使用liquibase時，在連接關閉錯誤後，我得到無操作允許
我得到錯誤後，我將我的sql分成5個文件。現在我得到了4. sql或5. sql文件中的錯誤。這似乎是隨機的。
我使用liquibase 3.1.1版本。
數據庫連接配置：
db.driver=com.mysql.jdbc.Driver
db.url=jdbc:mysql://localhost:3306/ls?zeroDateTimeBehavior=convertToNull&useUnicode=yes&characterEncoding=UTF-8&connectionCollation=utf8_general_ci
db.username=root
db.password=
這是我changelog.xml文件。
