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).
解决办法:
1、如果不需要数据库,把数据源去掉:
//去掉数据源,只需要添加:exclude = DataSourceAutoConfiguration.class @SpringBootApplication(exclude = DataSourceAutoConfiguration.class) public class DemoApplication { public static void main(String[] args) { SpringApplication.run(DemoApplication.class, args); } }
2、如果有数据库,看第二种:
<build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <!--这里写上main方法所在类的路径--> <configuration> <mainClass>com.example.demo.DemoApplication</mainClass> </configuration> <executions> <execution> <goals> <goal>repackage</goal> </goals> </execution> </executions> </plugin> </plugins> <resources> <resource> <directory>src/main/java</directory> <includes> <include>**/*.properties</include> <include>**/*.xml</include> </includes> <filtering>true</filtering> </resource> <resource> <directory>src/main/resources</directory> <includes> <include>*</include> <include>*/*</include> </includes> <filtering>true</filtering> </resource> <resource> <directory>src/main/webapp</directory> <targetPath>META-INF/resources</targetPath> <includes> <include>**/**</include> </includes> </resource> </resources> </build>
一定要把配置文件编译进去:
没添加前执行打包的图:
没有把配置文件打包进来,所以报错了
添加了<build>标签打包后:
