transactionAdviser (Spring 부트 응용 프로그램)의 NullPointerException

Question

스프링 부트 응용 프로그램을 개발하는 동안 이상한 예외가 있습니다. 나는 많은 것을 탐색했지만 구출에별로 도움이되지 못했다. 여기에 내가 무엇입니까 :

프로젝트가 오류없이 실행되고 올바르게 작동합니다. 나는 코드를 변경하지 않았고,이 예외를 한 순간에 얻었다. 사전에 https://github.com/oler117/oler-web-store

감사 :

다음

@Configuration 
@EnableTransactionManagement 
@EnableJpaRepositories({ 
     "com.webstore.common.repository.jpa", 
     "com.webstore.web.repository.jpa" 
}) 
public class JpaConfig implements TransactionManagementConfigurer { 

    @Value("${dataSource.url}") 
    private String datasourceUrl; 
    @Value("${dataSource.username}") 
    private String datasourceUsername; 
    @Value("${dataSource.password}") 
    private String datasourcePassword; 
    @Value("${dataSource.driverClassName}") 
    private String datasourceDriverClassName; 
    @Value("${hibernate.dialect}") 
    private String hibernateDialect; 
    @Value("${hibernate.hbm2ddl.auto}") 
    private String hibernateHbm2ddlAuto; 

    @Bean 
    public DataSource configureDataSource() { 
     HikariConfig hikariConfig = new HikariConfig(); 
     hikariConfig.setDriverClassName(datasourceDriverClassName); 
     hikariConfig.setJdbcUrl(datasourceUrl); 
     hikariConfig.setUsername(datasourceUsername); 
     hikariConfig.setPassword(datasourcePassword); 
     return new HikariDataSource(hikariConfig); 
    } 

    @Bean(name = "entityManagerFactory") 
    public LocalContainerEntityManagerFactoryBean configureEntityManagerFactory() { 
     LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean(); 
     entityManagerFactoryBean.setDataSource(configureDataSource()); 
     entityManagerFactoryBean.setPackagesToScan("com.webstore"); 
     entityManagerFactoryBean.setJpaVendorAdapter(new HibernateJpaVendorAdapter()); 

     Properties jpaProperties = new Properties(); 
     jpaProperties.put(org.hibernate.cfg.Environment.DIALECT, hibernateDialect); 
     jpaProperties.put(org.hibernate.cfg.Environment.HBM2DDL_AUTO, hibernateHbm2ddlAuto); 
     entityManagerFactoryBean.setJpaProperties(jpaProperties); 

     return entityManagerFactoryBean; 
    } 

    @Bean 
    @Override 
    public PlatformTransactionManager annotationDrivenTransactionManager() { 
     return new JpaTransactionManager(); 
    } 
}

여기 내 JpaConfig입니다!

Answer 1

pom.xml의 스냅 샷 버전 관리에 의존하고 있습니다. 즉, 완전히 버그가없는 최신 릴리스를 가져올 것입니다. 오류 메시지를 보면

spring-boot-1.4.0.BUILD-20160727.140415-585.jar:1.4.0.BUILD-SNAPSHOT 

오늘은 완전히 안정되지 않은 버전입니다. 대신 현재의 일반용 버전을 사용하여 안정성을 유지하십시오.
