Spring Boot - 使用Exclude的EnableAutoConfiguration不起作用 [英] Spring Boot - EnableAutoConfiguration with Exclude not working

问题描述

我正在使用最新的Spring启动版本，我正在尝试设置应用程序，但我想禁用DataSource配置。我的配置类如下所示：

  @Configuration 
 @ComponentScan 
 @EnableAutoConfiguration（exclude = {DataSourceAutoConfiguration .class}）
公共类ApiApplicationConfig {} 
  

但是当我运行应用程序时，我我得到以下stacktrace：

 引起：org.springframework.beans.factory.BeanCreationException：无法确定嵌入式数据库驱动程序类数据库类型NONE。如果您想要一个嵌入式数据库，请在类路径上放置一个受支持的数据库。

我错过了配置中的任何内容以完全禁用数据源配置？我将手动设置一个DataSource，所以我不希望Spring为我处理这个。

解决方案

这似乎是一个奇怪的情况，其中 DataSourceAutoConfiguration.NonEmbeddedDataSourceCondition 找到一个DataSource类加载器，但没有DataSource。我们在运行集成测试时遇到了spring-boot 1.2.2的问题。

无论如何，我们运行了 gradle依赖项找出在tomcat-jdbc中引入的内容，最后用普通的spring-jdbc替换spring-boot-jdbc依赖项。如果您的依赖项中没有tomcat-jdbc，则可以在 DataSourceAutoConfiguration.NonEmbeddedDataSourceCondition.getDataSourceClassLoader（）中设置断点，以找出它找到的驱动程序。 / p>

I am using the latest spring boot version and I am trying to setup an application but I want to disable the DataSource configuration. My configuration class looks like this:

@Configuration
@ComponentScan
@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
public class ApiApplicationConfig { }

but when I run the application, I am getting the following stacktrace:

Caused by: org.springframework.beans.factory.BeanCreationException: Cannot determine embedded database driver class for database type NONE. If you want an embedded database please put a supported one on the classpath.

Am I missing anything in my configuration to completely disable datasource configuration? I will be manually setting up a DataSource, so I dont want spring to handle this for me.

解决方案

This seems to be a weird situation where DataSourceAutoConfiguration.NonEmbeddedDataSourceCondition finds a DataSource class loader, but no DataSource. We had this problem with spring-boot 1.2.2 while running an integration test.

Anyway, we ran gradle dependencies to find out what was pulling in tomcat-jdbc and ended up replacing our spring-boot-jdbc dependency with plain spring-jdbc. If you don't have tomcat-jdbc in your dependencies, it may help to set a breakpoint in DataSourceAutoConfiguration.NonEmbeddedDataSourceCondition.getDataSourceClassLoader() to find out what driver it finds.
