スタンドアロンのTomcatでSpring Boot jdbcデータソースの自動設定が失敗する

スタンドアロンのTomcat（7）インスタンスでSpring Bootアプリケーションをデプロイして開始しようとしたときに、自動構成されたSpringデータソースBeanが見つからず、対応する例外がスローされるという問題が発生しました。

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: 
No qualifying bean of type [javax.sql.DataSource] found for dependency: 
expected at least 1 bean which qualifies as autowire candidate for this dependency.

単純なjdbc spring.datasourceはapplication.propertiesで適切に構成され、アプリケーション自体はスタンドアロンのSpringブートアプリケーションとして埋め込まれたTomcatインスタンスで完全に実行されます。

Application.propertiesファイルを正しく読み取ったり処理したりできないか、他のBean（RESTコントローラのサービスなど）のインジェクション）がデータソースの自動設定の前にトリガーされるようです行われました。

埋め込みTomcatを使用しない場合、追加の構成は必要ですか？または誰かが同様の問題に遭遇しましたか？

簡単なアプリケーションと構成：

@EnableAutoConfiguration
@Configuration
@ComponentScan("com.foo")
public class Application extends SpringBootServletInitializer {

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

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

}

application.properties：

spring.datasource.url=jdbc:mysql://localhost:3306/mydatabase
spring.datasource.username=username
spring.datasource.password=password
spring.datasource.driverClassName=com.mysql.jdbc.Driver

データソースの使用例：

@Repository
public class MyRepositoryImpl implements MyRepository {

    @Autowired
    private DataSource dataSource;

...
}

これは、使用している0.5.0.M6バージョンとTomcatバージョンの問題である可能性が高いです。 Spring Boot 0.5.0.M7およびTomcat 7.0.47で動作します。

こんにちは、JPAライブラリが欠落していないことを確認してください。

@EnableAutoConfiguration(exclude = { DataSourceAutoConfiguration.class,
        HibernateJpaAutoConfiguration.class,
        DataSourceTransactionManagerAutoConfiguration.class })

バージョン1.3.3のために私のために働いた

私は以前同じ問題に直面していましたが、同じことを追加することで解決しました

@PropertySource("classpath:application.properties")

application.Javaでこれが役立つことを願っています

私にとっては、JdbcTemplateAutoConfigurationで例外がスローされていました。 Application.Javaにexclude JdbcTemplateAutoConfigurationを追加しました。それが役に立てば幸い。

@SpringBootApplication(exclude = { DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class, JdbcTemplateAutoConfiguration.class })
