Question

我使用Spring boot版本1.3.5.RELEASE为我的应用程序。当我配置数据源时，它会抛出一些例外。它显示library.datasource.driver-class-name = com.mysql.jdbc.Driver library.datasource.url = jdbc:mysql://192.168.0.188:3306/library_keycloak?autoReconnect=true library.datasource.username = jijesh library.datasource.password = jijesh # Keep the connection alive if idle for a long time (needed in production) spring.datasource.testWhileIdle = true spring.datasource.timeBetweenEvictionRunsMillis = 60000 spring.datasource.validationQuery = SELECT 1 # Number of ms to wait before throwing an exception if no connection is available. spring.datasource.max-wait=10000 # Maximum number of active connections that can be allocated from this pool at the same time. spring.datasource.max-active=50 # Validate the connection before borrowing it from the pool. spring.datasource.test-on-borrow=true # Show or not log for each sql query spring.jpa.hibernate.connection.provider_class=org.hibernate.hikaricp.internal.HikariCPConnectionProvider spring.jpa.hibernate.hikari.minimumIdle=5 spring.jpa.hibernate.hikari.maximumPoolSize=10 # Show or not log for each sql query spring.jpa.show-sql = true spring.jpa.generate-ddl=true spring.jpa.database-platform=org.hibernate.dialect.MySQL5Dialect hibernate.temp.use_jdbc_metadata_defaults = false #Hibernate ddl auto (create, create-drop, update) #spring.jpa.hibernate.ddl-auto = update #spring.jpa.hibernate.ddl-auto = create-drop # Naming strategy spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy # Use spring.jpa.properties.* for Hibernate native properties (the prefix is # stripped before adding them to the entity manager) # The SQL dialect makes Hibernate generate better SQL for the chosen database spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect。
