记录springboot 启动时报错:If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

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).

从报错来看是启动时找不到数据库的url,但是项目之前时没有问题的,且已经合适过自己的配置和数据库运行结果,查询网上的说法,大概分成几种情况
1>添加 exclude = {DataSourceAutoConfiguration.class},排除springboot启动时的自动加载;
2>在pom.xml添加 <resource> <directory>src/main/resources</directory> <includes> <include>**/*.yml</include> </includes></resource> ,在pom.xml中指定加载的配置文件
3> 还有说时多个环境导致配置文件没有被加载正确
事实上我们启动的的代码时我们编译的target,首先需要确认target中的dataSource配置是否正确,这个时候发现target中并没有相应的*.yml文件;到这里我们真正的找到程序报错的原因,那么接下来就要解决是什么原因导致的target中没有相应的,这是因为我的pom.xml文件中增加了一条数据:<packaging>pom</packaging>,将该条信息删除,重新 mvn install,可以看到target下
,重新启动springboot就可以了
