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

我已经启动了mongod，输出如下:

当前回答

当我开始一个新项目时，我遇到了同样的错误。我用命令行就行。

./gradlew bootRun

我也有同样的问题，尝试了上面所有的建议，但都没有奏效。我把我的答案贴出来供将来的读者参考。之前它工作正常，但不知怎的它又出现了。我通过从pom.xml中删除一些不必要的插件和依赖来解决这个问题

First of all, I changed default packaging type to jar (Spring Boot Initializer gives pom in packaging) <packaging>jar</packaging> I added unintentional some plugins: <plugin> <artifactId>maven-war-plugin</artifactId> <configuration> <attachClasses>true</attachClasses> <webXml>target/web.xml</webXml> <webResources> <resource> <directory>src/main/webapp</directory> <filtering>true</filtering> </resource> </webResources> </configuration> </plugin>

我希望我的回答能帮助到一些人。

这可能是因为您有jpa依赖关系和插件……

如果不使用(build.;)Gradle或pom文件)

e . g。

// kotlin("plugin.jpa") version "1.3.61"

// implementation("org.springframework.boot:spring-boot-starter-data-jpa")

我认为当导入模块时，你已经导入了另一个包，去模块并删除它们。之后，从项目包中导入模块

在主java文件中添加此注释

@EnableAutoConfiguration(exclude=DataSourceAutoConfiguration.class)
