[SPRING] Sprint 부트 데이터 JPA : 'java.util.Set <javax.persistence.EntityManager>'유형의 유효한 bean이 없습니다.

Sprint 부트 데이터 JPA : 'java.util.Set '유형의 유효한 bean이 없습니다.

나는 spring-boot-startter-data-jpa로 시작할 수 없다. 나는이 가이드 다음에 간단한 Spring Boot app를 만들었지 만, Hibernate와 관련된 설정을 가지고있다.

build.gradle :

dependencies {
    // Spring stuff
    compile 'org.springframework.boot:spring-boot-starter-data-jpa:1.5.1.RELEASE'
    compile 'org.springframework.data:spring-data-jpa'
    compile 'org.springframework:spring-webmvc'
    // Jackson
    compile 'com.fasterxml.jackson.core:jackson-databind:+'
    compile 'com.fasterxml.jackson.dataformat:jackson-dataformat-yaml:+'
    // Postgres
    compile 'org.postgresql:postgresql:+'
    // Hibernate
    compile 'org.hibernate:hibernate-core:5.2.8.Final'
}

앱을 실행하려고 할 때마다 다음과 같이 끝납니다.

나는이 버그 (1.10.7로보고 된 바에 따르면 고정되어 있음)를 보았지만 spring-data-jpa를 1.9.x로 다운 그레이드하는 것은 도움이되지 않았지만 여전히 같은 오류가 발생했습니다.

어떤 아이디어?

해결법

1. ==============================

   1.문제는 최대 절전 모드 코어에 있습니다. 종속성에서 제거하면 문제가 해결됩니다.

   문제는 최대 절전 모드 코어에 있습니다. 종속성에서 제거하면 문제가 해결됩니다.

2. ==============================

   2.Spring Boot 2.0.3-RELEASE를 PostgreSQL 10에서 Hibernate / JPA와 함께 사용할 때도 같은 문제가있었습니다. JPA에는 다음과 같은 구성이 있습니다.

   Spring Boot 2.0.3-RELEASE를 PostgreSQL 10에서 Hibernate / JPA와 함께 사용할 때도 같은 문제가있었습니다. JPA에는 다음과 같은 구성이 있습니다.

   @EnableJpaRepositories
   public class DomainConfiguration {
   
      @Value("${database.password}")
      private String password;
   
      @Value("${database.url}")
      private String url;
   
      @Value("${database.username}")
      private String userName;
   
      @Bean
      public DataSource dataSource() {
         DriverManagerDataSource dataSource = new DriverManagerDataSource();
         dataSource.setDriverClassName(Driver.class.getCanonicalName());
         dataSource.setUrl(this.url);
         dataSource.setUsername(this.userName);
         dataSource.setPassword(this.password);
         return dataSource;
      }
   
      @Bean
      @DependsOn("flyway")
      public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
   
         HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
         vendorAdapter.setGenerateDdl(false);
   
         LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
         factory.setJpaVendorAdapter(vendorAdapter);
         factory.setJpaDialect(new HibernateJpaDialect());
         factory.setPersistenceUnitName("MTH");
         factory.setPackagesToScan("nl.mth.sync.domain");
         factory.setDataSource(dataSource());
         return factory;
      }
   
      @Bean
      public Flyway flyway(DataSource dataSource) {
         log.debug("--- configurating flyway ---");
         Flyway fly = new Flyway();
         fly.setDataSource(dataSource);
         fly.migrate();
         return fly;
      }
   
      @Bean
      public PlatformTransactionManager transactionManager(EntityManagerFactory entityManagerFactory) {
         JpaTransactionManager txManager = new JpaTransactionManager();
         txManager.setEntityManagerFactory(entityManagerFactory);
         return txManager;
      }
   

   그리고 다음 방법을 추가하여 문제를 해결했습니다.

      @Bean
      public EntityManager entityManager(LocalContainerEntityManagerFactoryBean localContainerEntityManagerFactoryBean) {
         return localContainerEntityManagerFactoryBean.getObject().createEntityManager();
      }
   

3. ==============================

   3.다음과 같이 표기법에 인수를 추가하여 해결할 수 있습니다.

   다음과 같이 표기법에 인수를 추가하여 해결할 수 있습니다.

   @SpringBootApplication
   

   이것은 주요한 방법 일 것입니다 :

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