spring cloud不需要操作数据库的模块由于引用其他公共模块,公共模块中依赖mybatis后,导致运行报错Failed to configure a DataSource。
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).
经查,因引入了myBatis的jar包:
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>1.3.1</version>
</dependency>
解决办法:
1、在@SpringBootApplication注解上加上exclude,解除自动加载DataSourceAutoConfiguration。
@EnableEurekaServer
@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
public class EurekaServerApplication {
public static void main(String[] args) {
SpringApplication.run(EurekaServerApplication.class, args);
}
}
2、在parent项目的pom.xml文件中保存所有子模块的共有jar依赖,非共有的依赖则在各模块自身的pom.xml文件中进行申明。建议采用此方法,好处在于各模块的依赖不会相互产生干扰。
