スタンドアロンの tomcat (7) インスタンスに 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に遭遇しました。
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException:

単純な jdbc spring.datasource は application.properties で適切に構成されており、アプリケーション自体は、組み込みの Tomcat インスタンスをスタンドアロンの Spring Boot アプリケーションとして完全に実行します。
application.properties ファイルを適切に読み取ったり処理したりできないか、データソースの自動構成が完了する前に他の Bean (たとえば、REST コントローラーのサービス) の注入がトリガーされたようです。
組み込みの tomcat を使用しない場合、追加の構成が必要ですか? または、誰かが同様の問題に遭遇しましたか?
シンプル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);
}
}
アプリケーションのプロパティ:
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;
...
}
