SQLSyntaxErrorException：表/视图'BUYER'不存在。缺什么？

标签： java sql orm jpa glassfish

几个星期前我去度假了，我暂停了一个项目。当我回来时，我只是检查注册页面，当我得到一个SQLException表示一个表不存在时，我感到很惊讶。我不明白，因为该表存在，我是从一个实体创建的。我在这里粘贴代码，这样你就可以看到一切似乎都没问题。我认为它可能与数据库有关（我使用glassfish 3 app服务器）。

以下是来自用户界面的图片，该图片说明问题与某些验证方法有关（检查用户是否已存在并检查电子邮件是否已存在）：

以防万一我也会打印stackTrace：

这是错误所说的问题所在的EJB：

@Stateless(name = "ejbs/BuyersRegistratorEJB")
public class BuyersRegistratorEJB implements IBuyersRegistratorEJB {
  @PersistenceContext
  private EntityManager em;

  @Override
  public Buyer createBuyer(Buyer buyer) {
    Date date = new Date();
    DateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");
    buyer.setRegistrationDate(dateFormat.format(date));

    boolean textPatterCorrect = false;
    // TODO: Prepare regular expresion also for serbian latin characters
    String simpleTextPatternText = "^[a-zA-Z0-9]+$";
    Pattern textPattern = null;
    Matcher nameMatcher = null;
    Matcher secondNameMatcher = null;
    Matcher nickNameMatcher = null;
    Matcher passwordMatcher = null;

    textPattern = Pattern.compile(simpleTextPatternText);
    nameMatcher = textPattern.matcher(buyer.getName());
    secondNameMatcher = textPattern.matcher(buyer.getSecondName());
    nickNameMatcher = textPattern.matcher(buyer.getNickName());
    passwordMatcher = textPattern.matcher(buyer.getPassword());

    if (nameMatcher.matches() && secondNameMatcher.matches()
        && nickNameMatcher.matches() && passwordMatcher.matches()) {
      textPatterCorrect = true;
    } else {
      System.out
          .println("SOME OF THE INPUT DO NOT MATCH THE REGULAR EXPRESION FOR TEXT!");
    }

    if (textPatterCorrect) {
      em.persist(buyer);// EJB validation passed. Handle the input to the
                // next layer.
      return buyer;
    } else {
      throw new RuntimeException(
          "[BuyersRegistrationEJB] Text format validation FAILED!");
    }
  }

  // This will check if the email already exists!
  @Override
  public boolean emailAlreadyExists(String value) {
    Query checkEmailExists = em
        .createQuery("SELECT COUNT(b.email) FROM Buyer b WHERE b.email=:emailparam");
    checkEmailExists.setParameter("emailparam", value);
    long matchCounter = 0;
    matchCounter = (Long) checkEmailExists.getSingleResult();
    if (matchCounter > 0) {
      return true;
    }
    return false;
  }

  // This will check if the nickName already exists!
  @Override
  public boolean nickNameAlreadyExists(String value) {
    Query nickNameExists = em.createQuery("SELECT COUNT(n.nickName) FROM Buyer n WHERE n.nickName=:nicknameparam");
    nickNameExists.setParameter("nicknameparam", value);
    long matchCounter = 0;
    matchCounter = (Long) nickNameExists.getSingleResult();
    if (matchCounter > 0) {
      return true;
    }
    return false;
  }
}

我也会发布我的配置文件：

这一切都在3周前正常工作，但现在却没有。我不知道出了什么问题。

2 个答案:

答案 0 :(得分：3)

有几个可能的原因：

  1. 您的表格已被删除
  2. 您的凭据无法再查看或访问
  3. 您的凭据已更改
  4. 您的配置已损坏或已更改
  5. 您正在查看错误的数据库或类似的内容。

    6. 你需要按顺序排列其中的每一个，你将得到答案。这很可能是其中之一：）

答案 1 :(得分：2)

我刚刚完成了这个问题。我在NetBeans中使用了电子商务Affablebean。我发现这段代码：

<resource-ref>
<description>Connects to database for AffableBean application</description>
<res-ref-name>jdbc/affablebean</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
<res-sharing-scope>Shareable</res-sharing-scope>

应该是这样的

<resource-ref>
<description>Connects to database for AffableBean application</description>
<res-ref-name>jdbc/affablebean</res-ref-name>
<res-type>javax.sql.ConnectionPoolDataSource</res-type>
<res-auth>Container</res-auth>
<res-sharing-scope>Shareable</res-sharing-scope>
