Parameters 使用参数进行HQL查询时出错

我有以下几节课定义了学生和课程之间的许多关系

课程类别：

import java.io.Serializable;

import javax.persistence.*;

import java.util.HashSet;
import java.util.Set;

@Entity
@Table(name = "course")
public class Course implements Serializable {

private String id;
private String title;
private String sched;
private int    units;

// The students enrolled in this class
private Set<Student> students = new HashSet<Student>();

public Course() {
    // empty const required by java bean
}

public Course(String course_id, String title, String sched, int units) {
    this.id = course_id;
    this.title = title;
    this.sched = sched;
    this.units = units;
}


@Id
@Column(name = "COURSE_ID")
public String getId() {
    return id;
}

public void setId(String id) {
    this.id = id;
}

    // Other setters/getters with mapping...

@ManyToMany
    @JoinTable(name = "student_course_join",
         joinColumns = @JoinColumn(name = "COURSE_ID"),
         inverseJoinColumns = @JoinColumn(name = "STUDENT_ID"))
public Set<Student> getStudents() {
    return this.students;
   }

    public void setStudents(Set<Student> students) {
        this.students = students;
   }


   public String toString() {
    return "Course - Id: " + id + " Title: " + title + " Sched: " + 
            sched + "Units: " + units;
   }
}

coure对象返回时带有有效的学生列表。我在查询课程信息时遇到问题。我正在使用以下查询：

Query query = session.createQuery("select distinct c from Course c where c.id = :id");
query.setParameter("id", id);
course = (Course)query.uniqueResult();

我得到以下HQL异常：

org.hibernate.LazyInitializationException:延迟初始化角色集合失败：
edu.univ.mht.domain.Course.students，没有课程或课程关闭

在本例中，我对检索学生列表不感兴趣，但Hibernate似乎在抱怨与学生列表相关的事情。我正在搜索的课程有一个有效的学生名单。即使我在db中搜索没有学生列表的课程，我也会得到这个例外

以下是为查询生成的HQL：

Hibernate: select course0_.COURSE_ID as COURSE1_0_, course0_.SCHED as SCHED0_, course0_.TITLE as TITLE0_, course0_.UNITS as UNITS0_ from course course0_ where course0_.COURSE_ID=?

以下是堆栈跟踪：

首先，您的映射是错误的。其中一个边必须是使用meppedBy属性的反向边，并且不能定义所使用的联接表，因为它已经在另一侧定义。第二：为什么要使用HQL查询以更好的方式完成Session.get（）所做的事情？第三，发布异常的堆栈跟踪。我敢打赌，异常不是由查询引起的，而是由一些代码引起的，这些代码稍后使用课程并访问其学生列表，但尚未加载。我确实尝试了您建议的映射，在课程类中，而不是在当前映射中，我尝试了@manytomy（mappedBy=“courses”，cascade=CascadeType.ALL）我还在课程类中尝试了@ManyToMany（mappedBy=“coures”，cascade=CascadeType.ALL），但在保存和删除学生时遇到了问题。JB-我只是返回并更改了课程类中的映射，并将映射更改为@ManyToMany（mappedBy=“courses”），但得到了相同的错误。我试图添加fetch=FetchType.LAZY，但没有效果。我还尝试使用session.get（当然，class，id）并得到了相同的结果。我有点没主意了非常感谢MikeLook的堆栈跟踪。执行查询时不会发生异常。它发生在JSP中，当您试图显示课程的学生时。您加载课程时没有初始化其学生，因此很明显，您会遇到此异常。确保在会话仍然打开（在您的服务或DAO中）时初始化学生（例如，通过调用

course.getStudents（）.size（）

）。

Hibernate: select course0_.COURSE_ID as COURSE1_0_, course0_.SCHED as SCHED0_, course0_.TITLE as TITLE0_, course0_.UNITS as UNITS0_ from course course0_ where course0_.COURSE_ID=?
