Java 由于相同的hibernate构造函数而导致NullPointerException
我正在使用Java 由于相同的hibernate构造函数而导致NullPointerException,java,hibernate,entitymanager,Java,Hibernate,Entitymanager,我正在使用hibernate4.2.0。我正在上以下课程： @Entity public class TestData { @Id @GeneratedValue private Long id; private String customerNr; private String FirstName; private String LastName; /** * */ public Tes
hibernate4.2.0@Entity
public class TestData {
@Id
@GeneratedValue
private Long id;
private String customerNr;
private String FirstName;
private String LastName;
/**

*/
public TestData() {
super();
}
/**
* @param customerNr
*/
public TestData(String customerNr) {
super();
this.customerNr = customerNr;
}
/**
* @param id
* @param customerNr
* @param firstName
* @param lastName
*/
public TestData(Long id, String customerNr, String firstName,
String lastName) {
super();
this.id = id;
this.customerNr = customerNr;
FirstName = firstName;
LastName = lastName;
}
//getter and setter etc.
}
@Transactional
@SuppressWarnings("all")
public List<TestData> getCustomerNrFilter(String customerNr) {
CriteriaBuilder cb = em.getCriteriaBuilder();
CriteriaQuery<TestData> criteria = cb.createQuery(TestData.class);
//which table we want to fetch
final Root root = criteria.from(TestData.class);
//create statement
criteria.select(cb.construct(TestData.class, root.get("customerNr"))).distinct(true);
// Pass the criteria list to the where method of criteria query
criteria.where(cb.and((Predicate[]) criteriaList.toArray(new Predicate[0])));
// Order by clause
criteria.orderBy(cb.asc(root.get("customerNr")));
return em.createQuery(criteria).getResultList();
}
public List createWhereCritera(String customerNr, CriteriaBuilder cb,
final Root root) {
// This list will contain all Predicates (where clauses)
List criteriaList = new ArrayList();
// CustomerNr: where condition: TestData.CustomerNr like '%'
Predicate predicateFirstName = cb.like(cb.upper(root.get("customerNr")),customerNr);
criteriaList.add(predicateFirstName);
return criteriaList;
