誰かがこれを助けることができますか?

現在、いくつかの問題に遭遇しました.spring、jpa、hibernateを使用しています。ここに問題があります。いくつかのオブジェクトを保存しようとした後、solrj が false を返したときのように手動でロールバックします。

私は次のことを試しました:
1. usertransaction (例外: Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException)

2. entitymanager.gettransaction().begin(例外: 共有マネージャー)

ありがとう、私が理解するのを手伝ってくれるなら。

ヘッダ:

@Service("jpaWallPostService")
@Repository
public class WallPostServiceImpl implements WallPostService {
    //........
    @PersistenceContext
    private EntityManager em;

======================================

  @Transactional(readOnly=false)
public boolean save(String solrURL,int userid,wall_post wallPost,List<String> groupsid,List<String> hashtag){


    try{
        em.getTransaction().begin();// ***error occur on here*** and stop here
        //...............proccess
        boolean ok = SolrJ.IndexingWallPost(solrURL,userid, wallPost.getTitle(), wallPost.getMessage(), hashtag,groupsid);
        if(!ok)
            em.getTransaction().rollback();



        em.getTransaction().commit();
        return true;
    }
    catch(Exception e)
    {
        em.getTransaction().rollback();
        return false;
    }
}

ここにエラーログがあります

問題は、save メソッドに Transactional アノテーションが付けられていることです。これは、トランザクションが Spring によって処理されることを意味しますが、メソッド内で、JPA API を使用してプログラムでトランザクションを管理しようとしています。

したがって、 2つのアプローチを誤って混合しています。理想的には、Transactional アノテーションのみを使用する必要があります。

以下に、これを処理する Spring ヘルパー クラスのソース コードを追加しました。関連するクラスは org.springframework.orm.jpa.SharedEntityManagerCreator です。プライベートな静的クラス SharedEntityManagerInvocationHandler があり、エラーがスローされる関連コードは以下のとおりです。

public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
  .....
  .....
  else if (method.getName().equals("getTransaction")) {
      throw new IllegalStateException("Not allowed to create transaction on shared"
                             +" EntityManager - use Spring transactions or EJB CMT instead");
.....
.....
  }

それで、これが私が上で述べたことです。

getTransaction メソッドを呼び出していますが、エラーが発生しています。

したがって、メソッド内のトランザクション処理を取り除き、Transactional アノテーションのみに固執します。
