java.lang.IllegalStateException：在查询执行过程中提供的参数列表中找不到查询参数

我是JPA与Netbeans和EclipseLink合作的新手，我创建了一个实体管理器以及一个PK类，主类。java.lang.IllegalStateException：在查询执行过程中提供的参数列表中找不到查询参数

当我尝试从NetBeans中

@NamedQuery(name = "Company.findUser", query = "SELECT c FROM Company c WHERE c.companyPK.user = :user") 
@NamedQuery(name = "Company.findPass", query = "SELECT c FROM Company c WHERE c.password = :password")

我笑脸相迎的错误使用上述

但

@NamedQuery(name = "Company.findAll", query = "SELECT c FROM Company c")

作品预生成的名称，并显示我的一切...... ...

公司：

@Entity 
@Table(name = "Company") 
@XmlRootElement 
@NamedQueries({ 
    @NamedQuery(name = "Company.findAll", query = "SELECT c FROM Company c"), 
    @NamedQuery(name = "Company.findUser", query = "SELECT c FROM Company c WHERE c.companyPK.user = :user"), 
    @NamedQuery(name = "Company.findPass", query = "SELECT c FROM Company c WHERE c.password = :password")}) 
public class Company implements Serializable { 
    private static final long serialVersionUID = 1L; 
    @EmbeddedId 
    protected CompanyPK companyPK; 
    @Column(name = "Password") 
    private String password;

CompanyPK：

@Basic(optional = false) 
@Column(name = "User") 
private String user;

AdminControl：

EntityManagerFactory emf = Persistence.createEntityManagerFactory("UploaderPU"); 
    EntityManager em = emf.createEntityManager(); 


    em.getTransaction().begin(); 
    Company c = new Company(new CompanyPK(userF.getText()),pass.getText()); 
    em.persist(c); 
    em.getTransaction().commit(); 


     // TypedQuery<Company> query = em.createNamedQuery("Company.findUser", Company.class); 
    Query q1 = em.createQuery("SELECT c FROM Company c WHERE c.companyPK.user = :user"); 
    System.out.println(q1.getSingleResult());

上面的代码是错误的，但如果使用Company.find所有/“SELECT c从公司c“我将在我的数据库中获取所有数据。

我知道数据也存储，因为我每次查询我的数据库netbeans查看结果。

有趣的是，如果我把两次相同的数据，即用户=一个2x，我会得到一个错误，说主键是重复的等等等等。

所以我知道它可以读取它，但为什么当它不是重复的时候出现错误？

在100 AdminResult线，您正在执行的命名查询的一个（你的帖子没有显示它，但它可能是Company.findUser）。该查询在JPQL中有一个参数:user。如果q是您查询，您需要做的

q.setParameter("user", someValue);

分配在查询执行时间的值到该参数。

另外，最好在一个查询中查询用户名和密码，并确保它返回一个命中。

对不起，我张贴这之前，我昏了过去，我知道我会忘记一些东西，我已经更新了“AdminControl”结束基本上这是什么做的是创造一个新的用户帐户;然而从你最后一句似乎建议你谈论的用户登录/认证的单个查询还是......？基本上我会在这个新的acc创建中存储大约3-4条信息到db中，所以我应该一起查询它们吗？谢谢。我会尝试设置参数，但我认为， begin（）; em.persist（c）; em.getTransaction（）。commit（）; 是什么工程。 – XaolingBao 2014-09-27 12:52:13

这结束了工作，谢谢。我最初是在看http://www.objectdb.com/java/jpa/start/crud ，但发现http://www.objectdb.com/java/jpa/query/parameter，所以我会检查更多，再次感谢。 – XaolingBao 2014-09-27 13:52:16
