Spring Boot的新功能。我正在尝试在Tomcat（8.0.30）服务器上运行Spring Boot应用程序。这是我的pom.xml：

这是配置类：

@EnableJpaRepositories("com.pr.hotels.apiconsumer")
@PropertySource("classpath:application.properties")
public class DataConfig
{

@Resource

public DataSource dataSource() throws NamingException
{

Context env = (Context) init.lookup("java:/comp/env/");
DataSource data = (DataSource) env.lookup("jdbc/hotels");
return data;
}
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() throws NamingException
{
LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
entityManagerFactoryBean.setDataSource(dataSource());
entityManagerFactoryBean.setPersistenceProviderClass(HibernatePersistenceProvider.class);
entityManagerFactoryBean.setPackagesToScan(env.getRequiredProperty(PROP_ENTITYMANAGER_PACKAGES_TO_SCAN));
entityManagerFactoryBean.setJpaProperties(getHibernateProperties());
return entityManagerFactoryBean;
}
@Bean
public JpaTransactionManager transactionManager() throws NamingException
{
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(entityManagerFactory().getObject());
return transactionManager;
}
private Properties getHibernateProperties()
{
Properties properties = new Properties();
properties.put(PROP_HIBERNATE_DIALECT, env.getRequiredProperty(PROP_HIBERNATE_DIALECT));
properties.put(PROP_HIBERNATE_SHOW_SQL, env.getRequiredProperty(PROP_HIBERNATE_SHOW_SQL));
properties.put(PROP_HIBERNATE_HBM2DDL_AUTO, env.getRequiredProperty(PROP_HIBERNATE_HBM2DDL_AUTO));
properties.put(PROP_LOB, env.getRequiredProperty(PROP_LOB));
return properties;
}
}
每次与关联的错误时ActiveMQ，但与ActiveMQ没有任何显式依赖关系（可能是我错了）。这是错误：

我究竟做错了什么？
最后，我在这里找到了答案https://stackoverflow.com/a/41326790/1912193需要ActiveMQAutoConfiguration从Spring Boot中排除。
