配置数据源失败:没有指定'url'属性，无法配置嵌入式数据源

我正在用MongoDB做一个Spring Boot Batch示例，我已经启动了mongod服务器。

当我启动我的应用程序时，我得到下面的错误。

对这个问题有什么建议吗?

***************************
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).

application.properties:

# Mongo database URI. Cannot be set with host, port and credentials.
spring.data.mongodb.uri=mongodb://localhost/test

pom.xml

我已经启动了mongod，输出如下:

我通过添加<scope>提供</scope>解决了同样的问题

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
            <scope>provided</scope>
        </dependency>

这个方法对我来说很管用，适用于MySQL: (应用程序属性)

spring.datasource.url=jdbc:mysql://localhost:3306/db?useSSL=false&useUnicode=true&useJDBCCompliantTimezoneShift=true&
useLegacyDatetimeCode=false&serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=admin
spring.jpa.hibernate.ddl-auto=create
spring.jpa.show-sql=true

如果您在pom.xml中添加了“spring-boot-start -data-jpa”依赖项，请在依赖项中添加相应的数据库，如h2等。

只需添加:@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class}) 对我有用。

我得到相同的错误，我尝试@EnableAutoConfiguration(排除=…)没有工作。

对于那些想知道在哪里添加@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})的人，因为它已经被用户问到了。你需要把它添加到主应用程序类，它在src>main>java下。默认情况下，它被设置为@SpringBootApplication

如果您使用YAML进行配置，那么可能会出现缩进问题。彻底检查YAML文件。

这并不是问题的关键(虽然可能是相关的)，但是，如果您引导一个新项目，并想知道为什么会得到相同的错误，它可能来自依赖项部分spring-boot-start -data-jpa的artifactId。我在下面给出了依赖关系。您将需要定义数据库来消除这种情况。

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
