我有2个数据源bean，我使用spring boot，spring数据，我用@primary注释标记了一个数据源bean，我仍然收到错误：No qualifying bean of type [javax.persistence.EntityManagerFactory] is defined:: expected single matching bean but found 2.
下面是我的2个数据库配置类：

private RelaxedPropertyResolver propertyResolver;
@Inject
private Environment env;
@Override
public void setEnvironment(Environment environment) {
this.propertyResolver = new RelaxedPropertyResolver(environment, "spring.datasource.primary.");
}
@Bean
@Primary
public DataSource dataSource() {
log.debug("Configuring Datasource");
if (propertyResolver.getProperty("url") == null && propertyResolver.getProperty("databaseName") == null) {
log.error("Your database connection pool configuration is incorrect! The application" +
"cannot start. Please check your Spring profile, current profiles are: {}",
Arrays.toString(env.getActiveProfiles()));
throw new ApplicationContextException("Database connection pool is not configured correctly");

你可以帮我解决这个问题，我该如何避免这个错误。
由于
答案 0 :(得分：0)
我认为你的＆＃34; cacheConfiguration＆＃34;需要通过注释指定它想要使用的持久性单元名称（@PersistenceUnit或@PersistenceContext）
