我有这样的事情：
StudentBean.java
@PersistenceContext
EntityManager em;
@Override
public Boolean addStudent(Student s) {
try{
// Student s1 = new Student(10,"asd", "asd"); //this was for testing
em.persist(s);
em.flush();
} catch (Exception ex) {
ex.printStackTrace();
}
return true;
}
然后我用这个构造函数得到了Student.java：
public Student(Integer studentId, String firstName, String lastName) {
this();
this.studentId = studentId;
this.firstName = firstName;
this.lastName = lastName;
}
我有一个UTest.java类用于测试函数... 我得到了这个：
@Test public void testAddStudent() {
StudentBean sb = new StudentBean();
Student s1 = new Student(4, "Ognjen", "Car");
System.out.println(s1.toString()); //it does not print anything
Boolean s = sb.addStudent(s1);
assert (s == true);
// fail("Not yet implemented");
}
当我运行测试时，它会显示此错误，而我根本无法找到答案，请帮助
