SpringBoot启动报错: Failed to configure a DataSource: url attribute is not specified and no embedded

 问题描述:

***************************
APPLICATION FAILED TO START
***************************
 
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).

原因是(我的情况):

项目中引入了外部jar包,然后在pom文件中,增加jar包路径的指引,应该是因为单独配置了jar包路径,然后springboot默认配置文件全走路径指引了,所以在pom文件中在增加对配置文件的路径指引就可以

	            lib
	            BOOT-INF/lib/
	            
	                **/*.jar
	            
	        
	        
	            src/main/resources
	            BOOT-INF/classes/
	        

这是我配置jar包的路径.

解决方法就是如下配置:

pom文件中增加对配置文件的路径指引

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

 

这个问题只在本地运行时出现了,因为线上部署的时候是吧配置文件放在jar包同级目录了,然后就不会出现找不到配置文件的问题.原因可以搜索一下
