問題描述:
***************************
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(我的情況):
項目中引入了外部jar包,然後在pom文件中,增加jar包路徑的指引,應該是因爲單獨配置了jar包路徑,然後springboot默認配置文件全走路徑指引了,所以在pom文件中在增加對配置文件的路徑指引就可以
<resource>
<directory>lib</directory>
<targetPath>BOOT-INF/lib/</targetPath>
<includes>
<include>**/*.jar</include>
</includes>
</resource>
<resource>
<directory>src/main/resources</directory>
<targetPath>BOOT-INF/classes/</targetPath>
</resource>
這是我配置jar包的路徑.
解決方法就是如下配置:
pom文件中增加對配置文件的路徑指引
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.yml</include>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>false</filtering>
</resource>
<resource>
<directory>src/main/resources</directory>
<includes>
<include>**/*.yml</include>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>false</filtering>
</resource>
這個問題只在本地運行時出現了,因爲線上部署的時候是吧配置文件放在jar包同級目錄了,然後就不會出現找不到配置文件的問題.原因可以搜索一下<springboot的配置文件加載優先級>
