I have a problem configuring sqlite3 with hibernate 5.2. When I launch the application I have the following exception: org.sqlite.SQLiteException: [SQLITE_ERROR] SQL error or missing database (no such column: type0_.id_type) at org.sqlite.core.DB.newSQLException(DB.java:909) ~[sqlite-jdbc-3.20.1.jar:na] at org.sqlite.core.DB.newSQLException(DB.java:921) ~[sqlite-jdbc-3.20.1.jar:na] at o
用hibernate 5.2配置sqlite3时遇到问题。 当我启动应用程序时，我有以下例外情况： org.sqlite.SQLiteException: [SQLITE_ERROR] SQL error or missing database (no such column: type0_.id_type) at org.sqlite.core.DB.newSQLException(DB.java:909) ~[sqlite-jdbc-3.20.1.jar:na] at org.sqlite.core.DB.newSQLException(DB.java:921) ~[sqlite-jdbc-3.20.1.jar:na] at org.sqlite.core.DB.throwex(DB.java:886) ~[
I have one Table in postgresql database with two id Sequence. @JsonProperty("id") @Column(name = "id", nullable = false,unique=true) @Id @GeneratedValue(strategy = GenerationType.IDENTITY,generator = "order_seq_gen") @SequenceGenerator(name = "order_seq_gen", sequenceName ="order_id_seq") private Integer id; @JsonProperty("state") private Strin
我在postgresql数据库中有两个id序列的表。 @JsonProperty（“id”）@Column（name =“id”，nullable = false，unique = true）@Id @GeneratedValue（strategy = GenerationType.IDENTITY，generator =“order_seq_gen”）@SequenceGenerator（name =“order_seq_gen”， sequenceName =“order_id_seq”） private Integer id; @JsonProperty("state") private String state; @JsonProperty("order_id") @Column(name="order_id", nul
Good day. So i have mapping @Id @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "discount_fares_id_sequence") @SequenceGenerator( name = "discount_fares_id_sequence", sequenceName = "discount_fares_id_seq", allocationSize = 1 ) private Long id; @Column private Long discount; @Column(name = "fare_code", length = 255) private String fareCode; @Many
美好的一天。 所以我已经映射@Id @GeneratedValue（strategy = GenerationType.SEQUENCE，generator =“discount_fares_id_sequence”）@SequenceGenerator（name =“discount_fares_id_sequence”，sequenceName =“discount_fares_id_seq”，allocationSize = 1）private Long id; @Column private Long discount; @Column(name = "fare_code", length = 255) private String fareCode; @ManyToOne @JoinColumn(name = "aircompa
I have a code which uses JPA annotations to generate DB primary key.A DB sequence is used to generate the PK.Am using Oracle DB @Id @Column(name = "rec_id", scale = 0) @GeneratedValue(generator = "RecIdSequence", strategy = GenerationType.SEQUENCE) @SequenceGenerator(name = "RecIdSequence", sequenceName = "P_REC_ID_SEQUENCE") public Long getRecordId() { return outboundPackageRecordId; } Now
我有一个代码使用JPA注释来生成DB主键。DB序列用于使用Oracle DB生成PK.Am @Id @Column(name = "rec_id", scale = 0) @GeneratedValue(generator = "RecIdSequence", strategy = GenerationType.SEQUENCE) @SequenceGenerator(name = "RecIdSequence", sequenceName = "P_REC_ID_SEQUENCE") public Long getRecordId() { return outboundPackageRecordId; } 现在我的理解是：DB定序器返回的序列ID用作rec_id。 它是否正确
to create a sequence on JPA I normaly use this @GeneratedValue(strategy=GenerationType.AUTO) @SequenceGenerator(name="example_sequence", sequenceName="example_sequence") But I want to create a sequence that is also generated automatically but it increments from 0 to 255 and when this value is acheived it restarts from zero you will need to create your own sequence generato
在JPA I上创建序列通常使用此@GeneratedValue（strategy = GenerationType.AUTO）@SequenceGenerator（name =“example_sequence”，sequenceName =“example_sequence”） 但是我想创建一个也是自动生成的序列，但它从0增加到255，当这个值达到时，它从零开始 您将需要创建自己的序列生成器 http://www.objectdb.com/api/java/jpa/SequenceGenerator http://openjpa.apache.org/builds/1.1.0/docs/jpa_overview_mapping_seq
I'm reading up on the activity lifecycle, and reading the documentation on starting and destroying activities, at the follow link: http://developer.android.com/training/basics/activity-lifecycle/starting.html The following text is from the link: Destroy the Activity While the activity's first lifecycle callback is onCreate(), its very last callback is onDestroy(). The system calls
我正在阅读活动生命周期，并阅读有关开始和销毁活动的文档，请点击以下链接：http://developer.android.com/training/basics/activity-lifecycle/starting.html 以下文字来自链接： 销毁活动 虽然活动的第一个生命周期回调函数是onCreate（），但它的最后一个回调函数是onDestroy（）。 系统在您的活动中调用此方法，作为您的活动实例从系统内存中完全删除的最终信号。 大多数应用程序不需要实现此方法，因为本地类引用
I have some questions about getting the version of application developed on top of libgdx (and also on robovm for ios) I want to get the version information That is declared in android:versionName tag of AndroidManifest.xml for Android That is declared in app.version key of robovm.properties for IOS. (Which, I believe, is eventually replaced for value of CFBundleShortVersionString key in I
我有一些关于获取在libgdx之上开发的应用程序版本的问题（以及针对ios的robovm） 我想获取版本信息 这是在android:versionName的AndroidManifest.xml android:versionName标记中声明的 这是在app.version的robovm.properties app.version密钥中robovm.properties的。 （我相信这最终将替换为Info.plist.xml中CFBundleShortVersionString键的值） 我的第一个问题是，libgdx提供了一个独立于平台的获取应用程序版本的方法
Id like to add an my app version and possibly build on the my SettingsActivity. Im trying to show an "About Phone" style activity on my app. But I dont know how to go about it. I am currently using EditTextPreference in my preference.xml which calls a dialog on Click, but I want it to be like this, where the onClick event doesnt produce a dialog.: SettingsActivity.java public cl
编号喜欢添加我的应用程序版本，并可能建立在我的设置活动。 我试图在我的应用上显示“关于手机”风格的活动。 但我不知道该怎么去做。 我目前在我的preference.xml中使用EditTextPreference，它在Click上调用对话框，但我希望它是这样的，onClick事件不会产生对话框。 SettingsActivity.java public class SettingsActivity extends PreferenceActivity { @Override protected void onCreate(Bundle savedInstanceState)
I want to add a "Check for update" button in apps so that when someone clicks it, it will display a toast message / progress dialog for checking the app's version. If new version is found the apps will auto download it to the phone and let user to manually install the updated apps. Or any others method will do as long as it can check for latest version and notify the user to upd
我想在应用程序中添加一个“检查更新”按钮，这样当有人点击它时，它会显示一个Toast消息/进度对话框来检查应用程序的版本。 如果找到新版本，应用程序会自动将其下载到手机，并让用户手动安装更新的应用程序。 或者只要可以检查最新版本并通知用户更新， 任何其他方法都会执行 。 Google在两个月前更新了Play商店。 这是我现在正在解决的解决方案.. class GetVersionCode extends AsyncTask<Void, String, String> {
如何检查Android手机是否处于横向或纵向状态？ The current configuration, as used to determine which resources to retrieve etc, as available from the Resources' Configuration object as: getResources().getConfiguration().orientation http://developer.android.com/reference/android/content/res/Configuration.html#orientation If you use getResources().getConfiguration().orientation on some devices
如何检查Android手机是否处于横向或纵向状态？ 当前配置用于确定要检索哪些资源等，可从资源的配置对象获取，如下所示： getResources().getConfiguration().orientation http://developer.android.com/reference/android/content/res/Configuration.html#orientation 如果你在某些设备上使用getResources（）。getConfiguration（）方向，你会发现它错了。 我们最初在http://apphance.com中使用了该方法。 感谢Apphance的
