Spring boot 无法从数据源（mysql）确定 jdbc url

Question

我正在尝试将 MySQL 数据库加载到 Spring Boot 应用程序中，但是当我启动应用程序时，我收到以下错误消息：

2018-07-17 13:46:31.426 WARN 2120 --- [ restartedMain] o.s.b.a.orm.jpa.DatabaseLookup : Unable to determine jdbc url from datasource

org.springframework.jdbc.support.MetaDataAccessException: Could not get Connection for extracting meta-data; nested exception is org.springframework.jdbc.CannotGetJdbcConnectionException: Failed to obtain JDBC Connection: 'url' not set

虽然我已经将 url 属性设置为application.properties：spring.datasource.url=jdbc:mysql://localhost:3306/mydatabase

谁能帮我解决这个问题？

编辑：这是我的主要课程：

package com.randomsoft.checkoff;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;

@SpringBootApplication
@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class})
public class CheckoffApplication {

public static void main(String[] args) {
    SpringApplication.run(CheckoffApplication.class, args);
}
}

Answer 1

您可以尝试删除 @EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class})

还尝试添加以下所有 jdbc 属性，

spring.datasource.url=jdbc:mysql://localhost:3306/mydatabase?verifyServerCertificate=false&useSSL=false&requireSSL=false
spring.datasource.username=<username>
spring.datasource.password=<password>
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.database-platform=org.hibernate.dialect.MySQL5Dialect
spring.jpa.hibernate.ddl-auto=update

Answer 2

只需尝试将此行附加到您的配置类中

@SpringBootApplication
@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
