小编Jos*_*dez的帖子

我正在使用Hibernate开发一个应用程序,当我连接数据库时,我得到一个Exception.例外是:

Unable to instantiate default tuplizer [org.hibernate.tuple.entity.PojoEntityTuplizer]

我的映射文件是:

<hibernate-mapping>
<class name="com.cartif.database.SetPoint" table="SetPoint">
    <id name="iSetPointId" column="setpointid" type="java.lang.Integer">
        <generator class="sequence">
            <param name="sequence">s_setpoint</param>
        </generator>
    </id>
    <property column="sensorType" generated="never" lazy="false" name="sSensortype" type="java.lang.String"/>
    <property column="value" generated="never" lazy="false" name="dValue" type="java.lang.Double"/>
    <property column="relationship" generated="never" lazy="false" name="sRelation" type="java.lang.String"/>
    <property column="deviceid" generated="never" lazy="false" name="iDeviceId" type="java.lang.Integer"/>
</class>
</hibernate-mapping>

并且包含getter/setter的课程不包括在内:

public class SetPoint {
    private int iSetPointId;
    private String sSensorType;
    private double dValue;
    private String sRelationship;
    private int iDeviceId;
}

我把javassist.jar包含在classpath中.我不知道是什么问题.有人会帮我.

谢谢!

我发现错误发生时.如果我在映射文件中包含属性抛出异常.如果我只声明表的id,则不抛出异常.可能的原因是什么？

完整的堆栈跟踪是:

162980 [btpool0-2 - /Gateway/zigbeedriver/app] ERROR org.hibernate.proxy.pojo.BasicLazyInitializer  - …

我正在使用线程.但是,当我尝试启动一个线程时,我得到一个例外.具体来说就是java.lang.IllegalThreadStateException.我的代码是:

public void readCommand() {
    readThread = new Thread("Thread for reading") {
        public void run() {
            while (running) {
                readBuffer = usbservice.receiveData();
                put(readBuffer);
            }
        }
    };
    readThread.start();
}

问题是什么？

我正在将Spring与Hibernate集成.但是,当我运行应用程序时,我得到一个错误,如:

在类路径资源[resources/spring.xml]中定义名为'sessionFactory'的bean时出错:init方法的调用失败; 嵌套异常是org.hibernate.HibernateException:无法获取默认的Bean Validation工厂

我的spring.xml看起来像:

我正在开发一个数据库连接器,以便从Oracle数据库中检索数据.我已经使用Hibernate工具作为Eclipse中的插件来生成Hibernate映射文件,因为我有很多要映射的类和表.但是,当我运行应用程序时,我刚刚得到以下异常:

java.lang.ClassCastException: org.hibernate.type.StringType cannot be cast to org.hibernate.type.VersionType
    at org.hibernate.tuple.PropertyFactory.buildVersionProperty(PropertyFactory.java:107)

我认为问题可能是hbm文件的属性类型:

<hibernate-mapping>

    <id name="role" type="string">
        <column name="ROLE" length="50" />

我想解析一个约会.我的字符串日期是"Thu Jan 19 2012 08:00 PM".我要解析的代码是:

format = new SimpleDateFormat("EEE MMM dd yyyy hh:mm aaa");
this.settDate(new Timestamp((format.parse(sDate)).getTime()));

但是,它不起作用.我怎么解析这个日期？

完整的方法是:

public void saveTask(int iDevice, String description, String sDate) throws ParseException {
    format = new SimpleDateFormat("EEE MMM dd yyyy hh:mm aaa");
    this.setiDeviceId(iDevice);
    this.setsDescription(description);
    this.settDate(new Timestamp((format.parse(sDate)).getTime()));
    DatabaseManager.save(this);
}

例外:

java.text.ParseException: Unparseable date: "Thu Jan 19 2012 01:00 AM"

调试图片:

谢谢!

我的GWT应用程序有问题.我在Jetty服务器上部署并运行.但是当我执行服务器调用(GWT的服务器包上的类)时,服务器返回错误消息.消息是:

7|0|6|http://localhost/zbapp/zb_app/|A31E1254E17F9AD731856D6BE34124A2|main.java.com.gwt.app.client.GreetingService|greetServer|java.lang.String/2004016611||1|2|3|4|2|5|5|6|6|
//EX[2,1,["com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException/3936916533","This application is out of date, please click the refresh button on your browser. ( Expecting version 5 from client, got 7. )"],0,5]

但是,服务器返回200代码即可.

我更新了浏览器,清理了浏览器缓存并重新编译了应用程序,但它没有运行.解决方案是什么？

提前致谢!

问候!

我是Spring DM的新成员,我想访问Bundlecontext.我的问题是我有一个与Activator捆绑,但它没有xml配置文件.我无法触摸此捆绑包,然后我需要访问BundleContext和serviceReference以获取我的捆绑包中的服务.我在捆绑中使用Spring DM.那么,我怎么能得到BundleContext？

谢谢!

问候!

我正在开发 GWT 应用程序。该应用程序正在服务器中运行。好吧，我实现了一个按钮，该按钮调用在服务器端生成本地文件的方法。但是我想在客户端下载/生成这个文件。我怎样才能在 GWT 中做到这一点？

谢谢

我正在使用Eclipse.在我开发过程中一切都是正确的,但我有两天有一些奇怪的问题.我有一个包含几个包的子项目.我想在包之间使用一些类,Eclipse会识别导入.但是,当我尝试导入时,它表明无法解析导入.我看到了日志文件,我得到了下一行:

非常感谢!祝你今天愉快!

我想知道如何开发一个Handler来管理用户键入ENTER密钥.例如,在登录屏幕上,您键入登录名和密码,然后按下ENTER.是否需要在RootPanel中添加Handler？在一个按钮？我不知道.

提前感谢您的解决方案.
