使用 JDBC、tomcat 和 jpa 获取 oracle 连接

Question

我正在将一个 Web 服务从 .NET WCF 移植到一个独立的 Java Web 服务，该 Web 服务具有一些有助于控制的非生成类。

我很难理解连接到 Oracle 数据库 10g 的所有选项。我一直在扫描互联网，试图找到一种简单的方法来获得连接或使用 Spring Boot 提供的默认设置。

或多或少是我想要的： Connection conn = DriverManager.getConnection("connectionDB")

我在 Maven 中使用 Spring Boot、spring、jpa 和 tomcat (8.5) 连接池。这是 POM 文件：

这是我的 application.properties 文件：

spring.datasource.url=jdbc:oracle:oci:@tnsDBName
spring.datasource.username=usr
spring.datasource.password=pass
spring.datasource.driver-class-name=oracle.jdbc.OracleDriver

#hibernate config
spring.jpa.database-platform=org.hibernate.dialect.Oracle10gDialect

任何帮助将不胜感激。

你能解释一下你想要达到什么目标吗？如果您只需要设置与数据库（数据源）的连接，有两种方法：

• 使用application.properties (spring.datasource.*)，例如 spring.datasource.url= db_url

• 通过编写Java配置类 使用 @Configuration 注释，您可以阅读更多关于它的信息 here
