Java Spring到Spring引导迁移。嵌入式Spring数据源

目前，它已被用于SpringBoot应用程序的自定义数据源配置，如下面所示

之前

@SpringBootApplication(exclude={DataSourceAutoConfiguration.class, MongoAutoConfiguration.class})
public class SpringBootAppInitializer {

    public static void main(String[] args) {
        System.setProperty("java.awt.headless", "false");
        SpringApplication.run(SpringBootAppInitializer.class);
    }
}

---

上述代码正在运行

之后 （要使用嵌入式数据源，请删除数据源自动配置排除或vs）

另外，我正试图使用两组相同的属性使其正常工作，一组是整个教程中使用的标准属性，另一组是Spring boot中嵌入的Hikari impl。 Octava项目的业务子模块中的D:\Projects\Octava\Business\src\main\resources\application-businessProduction.properties文件的一部分

spring.datasource.platform=postgresql
spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.data=data-postgresql.sql
spring.datasource.url=jdbc:postgresql://localhost:5432/octavadb
spring.datasource.initialization-mode=always
spring.datasource.username=postgres
spring.datasource.password=1

duplicated props for HIkari impl
spring.datasource.hikari.connectionTimeout=30000
spring.datasource.hikari.idleTimeout=600000
spring.datasource.hikari.maxLifetime=1800000
spring.datasource.hikari.driver-class-name=org.postgresql.Driver
spring.datasource.hikari.data-source-properties.hibernate.hbm2ddl.import_files=classpath:data-postgresql.sql
spring.datasource.hikari.jdbc-url=jdbc:postgresql://localhost:5432/octavadb
spring.datasource.hikari.username=postgres
spring.datasource.hikari.password=1

现在，我正在尝试删除自定义数据源创建并使用嵌入式数据源。但这两组属性都不起作用

以下是嵌入式Hikari数据源的初始化

为什么这种方法不起作用，也许还有其他选择

更新：

IntelliJ IDEA重新启动后，将创建数据源，但出现新的异常

所以，我终于把它修好了

• 主要修复是从这里开始的 这都是关于依赖性的
• 还有，检查一下这个 在我的例子中没有这样做，但可能会有助于为旧的实现添加关闭/销毁方法

最终属性是（删除了spring.datasource.hikari.prefix的属性）

Gradle改变以使其工作

    compile('com.zaxxer:HikariCP:2.7.6') {
        exclude group: 'org.hibernate', module: 'hibernate-core'
    }
    compile('org.hibernate:hibernate-hikaricp:4.3.8.Final') {
        //they are pulled in separately elsewhere, to avoid version conflicts
        exclude group: 'org.hibernate', module: 'hibernate-core'
        exclude group: 'com.zaxxer', module: 'HikariCP'
    }

我不完全清楚你想做什么。属性显示未嵌入的postgresql数据库的配置。从调试断点看，似乎没有加载属性。如果您实际上正在尝试配置嵌入式数据库（而不是postgres），那么请检查显而易见的情况：您在运行时类路径上有一个嵌入式数据库（H2、HSQL、Derby等），对吗？如果没有得到有用的答案，您可能希望尝试澄清您的问题；我根本不想使用嵌入式数据库。只是尝试将SpringBootOOTB数据源bean配置（DataSource.class）与仅使用属性一起使用。因此，主要目标是不再手动创建DataSourceBean（在我的例子中是BasicDataSource）。UPD:restart my Intelij IDEA数据源开始工作，但使用web应用程序[ROOT]似乎启动了一个名为[Hikariol-1 housekeeper]的线程，但未能停止它。这很可能会造成内存泄漏。

Description:

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.

Reason: Failed to determine a suitable driver class


Action:

Consider the following:
    If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
    If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).
