我正在使用MongoDB处理 Spring Boot Batch 示例，并且我已经启动了mongod服务器.

I am working on a Spring Boot Batch example with MongoDB and I have already started the mongod server.

启动应用程序时，出现以下错误.

When I launch my application, I am getting the error below.

这个问题有什么指针吗?

Any pointers for this issue?

*************************** 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

我已经开始mongod并显示以下输出:

推荐答案

检查您的application.properties

check your application.properties

改变

spring.datasource.driverClassName=com.mysql.jdbc.Driver

到

spring.datasource.driver-class-name=com.mysql.jdbc.Driver

为我工作.完整配置:

spring.datasource.url=jdbc:mysql://localhost:3306/db spring.datasource.username= spring.datasource.password= spring.datasource.driver-class-name=com.mysql.jdbc.Driver spring.jpa.database-platform = org.hibernate.dialect.MySQL5Dialect spring.jpa.generate-ddl=true spring.jpa.hibernate.ddl-auto = update
