DataSourceの構成に失敗しました： 'url'属性が指定されておらず、埋め込みデータソースを構成できませんでした。春

同様の質問をすべて確認しましたが、すべての回答で、すでに行っているdriverClassNameを指定する必要があると言われています。ここに私のapplication.ymlがあります：

spring:
  application:
    name: cibus-backend
  datasource:
    driverClassName: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/Cibus?useSSL=true
    username: root
    password: 1234567890
  jpa:
    show-sql: true
    hibernate:
      ddl-auto: update
      properties:
      hibernate:
        format_sql: true
        type: trace
    database-platform: org.hibernate.dialect.MySQL5InnoDBDialect
    database: mysql
logging:
  level:
    org:
      hibernate:
        type: trace

何か不足していますか？奇妙なことは、同じコードを持っている私のクラスメートがアプリを完璧に起動できるということです。これが私がそれがパスと関係があると思う理由です。たぶん、春はymlファイルにアクセスしていないのでしょう。 Springが検索するデフォルトの場所であるsrc.main.resourcesに含めました。スタックトレースは次のとおりです。

Error starting ApplicationContext. To display the conditions report re-run         
your application with 'debug' enabled.
2018-10-21 10:13:15.657 ERROR 10356 --- [JavaFX-Launcher]             
o.s.b.d.LoggingFailureAnalysisReporter   : 

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

これを含めるように求められたGradleビルドは次のとおりです。

buildscript {
    ext {
        springBootVersion = '2.0.5.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

apply plugin: 'Java'
apply plugin: 'Eclipse'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

group = ''
version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8
repositories {
    mavenCentral()
    jcenter()
}


dependencies {
    compile('org.springframework.boot:spring-boot-starter-data-jpa')
    runtime('mysql:mysql-connector-Java')
    testCompile('org.springframework.boot:spring-boot-starter-test')
    // https://mvnrepository.com/artifact/mysql/mysql-connector-Java
    compile group: 'mysql', name: 'mysql-connector-Java', version: '8.0.12'

    compileOnly 'org.projectlombok:lombok:1.18.2'
    annotationProcessor "org.projectlombok:lombok:1.18.2"
}

何か案は？前もって感謝します。

修正するには

組み込みデータベースエラーを特定できません

Spring BootアプリケーションクラスでDataSourceの自動構成を除外してみてください。これはEnableAutoConfigurationを使用して実行できます

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

また、言及する価値があるのは、コトリンでこれがどのように見えるかです：

@SpringBootApplication(
    exclude = [DataSourceAutoConfiguration::class]
)
class Launcher
...

... kotlinを書いているが、同じエラーでここに来た人のために。

Ymlファイル形式が正しくありません。開始行を

spring:
  ...
  datasource:
    driverClassName: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/Cibus?useSSL=true
    username: root
    password: 1234567890

すべてのファイルで必要に応じてこの形式のスペースを保持します

JPAおよび Hibernate を使用したSpring Bootの例：

spring.datasource.type = com.zaxxer.hikari.HikariDataSource spring.datasource.url = jdbc：postgresql：// localhost：5432/somedb

リンクで他のプロパティを確認できます

私のために働いた解決策は次のとおりです

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

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

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