java - HikariPool-1 - 驱动程序不支持获取/设置连接的网络超时。 (com.mysql.jdbc.JDBC4Connection.getNetworkTimeout()I)

Question

我正在使用 Spring Boot 和 Hibernate 创建一个简单的 Maven 项目，我想使用 Hibernate 在 mysqlDB 中创建我的表。当我运行 Spring 应用程序时，它不会创建我的表，我没有错误，但会出现标题按摩，我认为这就是我的问题的原因

`2019-05-31 14:02:54.781  INFO 25517 --- [  restartedMain] com.zaxxer.hikari.pool.PoolBase          : HikariPool-1 - Driver does not support get/set network timeout for connections. (com.mysql.jdbc.JDBC4Connection.getNetworkTimeout()I)`

Answer 1

查看您的日志，在我看来，hibernate 正在使用 hibernate.properties 中的属性

2019-05-31 14:35:56.164  INFO 26667 --- [  restartedMain] org.hibernate.cfg.Environment            : HHH000205: Loaded properties from resource hibernate.properties: {jdbc.url=jdbc:mysql://localhost/3306/test, hibernate.dialect=org.hibernate.dialect.H2Dialect, hibernate.show_sql=true, jdbc.user=root, hibernate.bytecode.use_reflection_optimizer=false, hibernate.hbm2ddl.auto=create-drop, jdbc.driverClassName=org.h2.Driver, jdbc.pass=dani861}

此行显示它正在尝试使用 H2 数据库作为驱动程序和方言。

在您的 pom.xml 中，您声明了对 spring data jpa 和 hibernate 的所有依赖项，但使用 spring boot 如果您使用 spring-boot-starter-jpa 依赖项，则更有意义。它提供自动配置类来帮助您。
