兩個持久單元和「無法解析與persistence-context-ref-name對應的持久單元」錯誤

我在寫Spring/JPA項目，我需要兩個數據庫的持久單元。當只有一個 - 一切都很好，但是當我添加第二持續性單元，我收到以下錯誤：兩個持久單元和「無法解析與persistence-context-ref-name對應的持久單元」錯誤

連接池：

Resource Type: javax.sql.XADataSource 
Datasource Classname: com.microsoft.sqlserver.jdbc.SQLServerXADataSource

DAO類：

@Repository 
@Transactional(value = "CentralTransactionManager") 
public class BranchDAO { 

    protected EntityManagerFactory emf; 
    private EntityManager em; 

    @PersistenceContext(unitName = "qp_centralPU")

    } 
}

請幫幫忙！

你如何檢索你的類中的'EntityManager'？我想還沒有在那裏指定PersistenceUnit ... – unwichtich

將你的'peristence.xml'重命名爲別的東西，並明確聲明哪一個用於'LocalContainerEntityManagerFactory'。「persistence.xml」的存在觸發GlassFish掃描「@PersistenceUnit」和「@PersistenceContext」註釋，並將應用程序視爲EJB3應用程序。 –

@ unwichtich，'public class BranchGroupDAO {0} { }受保護的EntityManagerFactory emf; private EntityManager em; @PersistenceUnit（的unitName = 「qp_centralPU」） @Qualifier（值= 「CentralEmf」）公共無效setEntityManagerFactory（EntityManagerFactory的電動勢）{ this.emf =電動勢; em = emf.createEntityManager（）; } public List getAllBranchGroups（）{ List brList = null; brList = em.createQuery（「SELECT b FROM BranchGroup b」）。getResultList（）; return brList; } } ' –

我在一個JPA + Spring + Glassfish項目中遇到了兩個持久單元的相同錯誤。

有兩個提示該結合導致了成功：

第一個是this，並且第二個是this。
