Hibernate认为参数为null

标签： java hibernate

我最近一直在使用数据库和休眠。

我正在尝试在两个表之间创建ManyToOne关系。

一个Testobject可以有多个CheckResults。 一个CheckResult与一个Testobject相关。

传递给addTestObject方法的对象已使用ids设置所有值。 Hibernate无法识别这些值，并希望将null写入数据库。

为什么？

我请求帮助。

更新：所以，我查看了代码。我先调用方法updatetestObject。这将在数​​据库中生成一个新条目就好了。然后我也会存储Checkresults。但是，当我这样做时，Hibernate的值为null（在调试控制台中，我看到了对象的正确值。）

更新II：当我从两个（testObject和CheckResult）中删除级联时，TestObjects存储在数据库中，但不存储CheckResults。 因此，对象和数据不为空。

更新III： 我删除了级联

@ManyToOne(cascade = {}, fetch = FetchType.LAZY)
    @JoinColumn(name = "testObject_id")
    private TestObject testObject = new TestObject();

现在我收到错误：

insert 
    into
        checkresult
        (name_id, error_typ_id, message, test_object_id, timestamp) 
    values
        (?, ?, ?, ?, ?)

org.hibernate.TransientPropertyValueException: object references an unsaved transient instance - save the transient instance before flushing.

更新IV： 我试图遍历CheckResults并将Testobject分配给它。现在错误消失了，但我为每个CheckResult获得了两倍的条目。

原件：

@Override
public synchronized TestObject addTestObject(Data.TestObject testObject){
    if (!testobjectDao.testObjectExists(testObject.getMrn())) {
        DbtestObject db = new DbtestObject();
        db.setOrganization(getOrganizationByName(testObject.getOrganizationId()));
        db.setMrn(testObject.getMrn());
        db.setName(testObject.getName());
        testobjectDao.addTestObject(db);
    }
    return testobjectDao.getTestobject(testObject.getMrn());
}

@Override
public synchronized boolean updateTestObject(Data.TestObject testObject, List<CheckResult> checkResults) {
    DbtestObject db = addTestObject(testObject);
    db.setCheckResults(convertCheckResults(checkResults));
    testobjectDao.addTestObject(db);
    return true;
}

来自DAO的方法

@Override
    public void addTestObject(TestObject testObject) {
        entityManager.persist(testObject);
    }

的TestObject 

@Entity
@Table(name = "testobject")
public class TestObject {
    @Id
    @Column(name="testobject_id", unique = true, nullable = false)
    @GeneratedValue(strategy = GenerationType.AUTO)
    private int id;

    @Column(name = "mrn", nullable = false, unique = true)
    private String mrn;

    @Column(name = "name", nullable = false)
    private String name;

    @ManyToOne(cascade = CascadeType.ALL)
    @JoinColumn(name="organization_id", nullable = false)
    private Organization organization;

    @OneToMany(cascade = {CascadeType.ALL}, mappedBy = "testObject")
    private List<CheckResult> checkResults = new ArrayList<>();

CheckResult 

@Entity
@Table(name = "checkresult")
public class CheckResult {
    @Id
    @Column(name="checkresult_id", unique = true, nullable = false)
    @GeneratedValue(strategy = GenerationType.AUTO)
    private int id;

    @Column(name = "timestamp")
    private Timestamp timestamp;

    @Column(name = "message", nullable = false, columnDefinition="LONGTEXT")
    private String message;

    @OneToOne(cascade = CascadeType.ALL)
    @JoinColumn(name="name_id", nullable = false)
    private CheckName checkName;

    @OneToOne(cascade = CascadeType.ALL)
    @JoinColumn(name="error_typ_id", nullable = false)
    private ErrorTyp errorTyp;

    @ManyToOne(cascade = CascadeType.ALL)
    @JoinColumn(name = "testobject_id")
    private TestObject testObject = new TestObject();

找到解决方案。

删除了从Testopject到TestResult的所有关系。

TestResult中：

@ManyToOne(cascade = {CascadeType.ALL}, fetch = FetchType.LAZY)
    @JoinColumn(name = "testObject_id")
    private TestObject testObject = new TestObject();

然后将TestObject设置为每个TestResult并将它们存储到数据库中。
