我在Eclipse中创建了一个Spring / Maven项目。然后我把它放在svn下的服务器上。然后我使用import＆gt;再次在Eclipse中导入它; maven项目等。
我当前的App.java应用程序包含以下代码：
package com.mycomany.app;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
@EnableAutoConfiguration
public class App {
public static void main(String[] args) {
SpringApplication.run(App.class, args);
}
}
但是当我尝试运行此文件时，我收到此错误：

我不知道为什么我遇到这个问题，但我想我不应该有这个问题。我对这些事情很陌生。

由于您的课程使用SpringBootApplication进行了注释，因此不需要EnableAutoConfiguration。
通过堆栈跟踪，Spring容器无法确定嵌入式数据库的类型。在您的pom.xml文件中，包含以下依赖项
<dependency>
<groupId>org.hsqldb</groupId>
<artifactId>hsqldb</artifactId>
<scope>runtime</scope>
</dependency>
或以下内容
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>
</dependency>

问题可能在于：测试类不在特定的程序包中。当我将测试类放到根目录时，我会看到一条类似的消息
答案 2 :(得分：0)
添加依赖项后我遇到了同样的问题
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
进入 pom.xml 。
解决方案是在application.properties中定义数据库设置。就我而言，我添加了下一个：
spring.datasource.driverClassName=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost:5432/webdemodb
spring.datasource.username=postgres
spring.datasource.password=1
spring.jpa.database-platform=org.hibernate.dialect.PostgreSQL95Dialect
spring.jpa.generate-ddl=true
spring.jpa.show-sql=true
spring.datasource.sql-script-encoding=UTF-8

在 DataSource 返回类型方法中删除@Bean批注。
答案 4 :(得分：0)
确保您在 .properties 文件中指定了正确的驱动程序。
例如 postgres：spring.datasource.driverClassName=org.postgresql.Driver
答案 5 :(得分：-1)
这个springboot启动类添加注释@EnableAutoConfiguration（exclude = {DataSourceAutoConfiguration.class}）
