当我尝试添加应用和应用设置时,我收到以下错误。 以下是详细的错误消息:

21:23:15错误SqlExceptionHelper:146 - Column' company_id'不能为空
这是junit测试
@Test
public void testsSaveApps() {
List<AppSetting> settings = new ArrayList<AppSetting>();
//int settingid = types.getMaxSettingId()+1;
settings.add(createSettingsOne());
settings.add(createSettingsTwo());
assertEquals(true,types.addTVappsWithSettings( 1,13, "App1", settings, "Danka" ) );
}
private static AppSetting createSettingsOne(){
AppSetting setting = new AppSetting();
setting.setCreated_by("Kasun");
LocalDateTime time = new LocalDateTime();
setting.setCreated_time(time);
setting.setDisplayOrder(1);
setting.setEditable(true);
setting.setSettings_key("url");
setting.setSettings_value("www.google.com");
setting.setUpdated_time(time);
setting.setUpdated_by("Kasun");
//setting.setSettings_id(settingid);
return setting;
}
private static AppSetting createSettingsTwo(){
AppSetting setting = new AppSetting();
setting.setCreated_by("Kasun");
LocalDateTime time = new LocalDateTime();
setting.setCreated_time(time);
setting.setDisplayOrder(2);
setting.setEditable(true);
setting.setSettings_key("url2");
setting.setSettings_value("www.CBC.com");
setting.setUpdated_time(time);
setting.setUpdated_by("Kasun");
//setting.setSettings_id(settingid);
return setting;
}
这是应用和设置保存方法
public boolean addTVappsWithSettings(int appTypeId,int companyid, String appName, List<AppSetting> settings, String createdBy) {
//set properties of the app to persist
App app = new App();
//app.setSettings_id(settingid);
// app.setSettings_id(settingid);
app.setApp_id(appTypeId);
app.setCompany_id(companyid);
app.setApp_name(appName);
app.setCreated_by(createdBy);
LocalDateTime created_time = new LocalDateTime();
app.setCreated_time(created_time);
app.setUpdated_by(createdBy);
app.setUpdated_time(created_time);
app.setEnable(true);
app.setapps(settings);
session.save(app);
if (!HibernateUtil.INSTANCE.commitTransaction())
return false;
return true;
}
这些是DAO课程。
@Entity

private LocalDateTime update_time;
@Column(name= "updated_by", nullable = false)

@Column(name= "enable", nullable = false)

这是App DAO

@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "settings_id", insertable = false, updatable = false)

@ElementCollection

private List<AppSetting> tvsettings = new ArrayList<AppSetting>();
@Column(name = "company_id", insertable = false, updatable = false)

为什么我会收到上述错误?如果您需要更多信息,请告诉我们。
更新

答案 0 :(得分:4)
在您的情况下,您已将OneToMany作为company_id的拥有方。即公司类拥有一方。
在此方案中,插入App记录会导致两个查询,一个插入和一个更新。首先是insert语句,它在没有company_id的情况下执行插入到App表中(因为这不是拥有方),然后它会触发更新查询来更新company_id。因此,要使第一个insert语句成功,它需要company_id为数据库中的空字段。否则会抛出ConstraintViolationException。
如果您将ManyToOne作为拥有方,那么它会在App表中生成一个insert语句。因此,在这种情况下,company_id字段可以为null。
因此,我看到两个选项:
以下输出有助于理解上述陈述。我有Forest类,它与Tree类具有OneToMany关系。
与许多人一对一的
Hibernate: values identity_val_local()
Hibernate: insert into Tree (id, "COUNT", FOREST, name, version) values (default, ?, ?, ?, ?)
与一对多的一面
Hibernate: insert into Tree (id, "COUNT", name, version) values (default, ?, ?, ?)
Hibernate: values identity_val_local()
Hibernate: update Tree set FOREST=?, index=? where id=?
答案 1 :(得分:0)
问题似乎出现在App.java
中@Column(name = "company_id", insertable = false, updatable = false)
private int company_id;
通过设置insertable = false
,您告诉Hibernate不要将其包含在INSERT语句中。有了这个和updatable = false
,如果没有明确的查询,你就永远无法设置它。
答案 2 :(得分:0)
查看company_id antite的名称,它与数据库中的名称相同。如果是,则必须在表单级别提供公司ID。
答案 3 :(得分:-1)
我有同样的错误。我试图保存具有空值的实体。(数据库对A列具有Not Null约束,并且实体中的列具有空值)。
