springboot配置数据源错误得几种原因分析及解决方式

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).

Disconnected from the target VM, address: '127.0.0.1:55284', transport: 'socket'

Process finished with exit code 0

写项目得过程中遇到了上面得错误,寻找了好久没有找到原因,在网上看了很多博客都大同小异,并没有解决我得问题。在这里说一下我得问题:自己得数据源配置得没有问题,但是启动得时候总是抛出上面得异常。后来发现是application-druid.yml没有被扫描到,后来在maven中加入了插件:

默认maven在src/main/java中只编译java文件,其他的文件会被忽略,但可以通过配置pom.xml,改变默认的设置,但在此建议,非java相关的资源,写在src/main/resources中比较好,这样条理清晰。

问题:maven打包时 ,src/main/java目录下的xml等资源文件打包不进去

解决方法:在pom.xml文件的标签中添加以下内容
 


            
                
                    src/main/java
                    
                        **/*.xml
                        **/*.yml
                        **/*.properties
                    
                    true
                
                
                    src/main/resources
                    
                        **/*.xml
                        **/*.yml
                        **/*.properties
                    
                    true
