无法实例化默认tuplizer [org.hibernate.tuple.entity.PojoEntityTuplizer]

时间：2012-01-17 07:42:34

标签： java database hibernate

我正在使用Hibernate开发一个应用程序，当我连接数据库时出现异常。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>

包含getter / setter的课程：

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

我将javassist.jar包含在classpath中。我不知道是什么问题。有人会帮助我。

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：

我也面临同样的问题。

添加了相同的依赖项并且它有效（如下所示）：

<dependency>
    <groupId>javassist</groupId>
    <artifactId>javassist</artifactId>
    <version>3.12.1.GA</version>
</dependency>

答案 1 :(得分：48)

当我遇到这个错误时，修复很简单。我只是错过了一个房产的二传手。确保为所有属性定义匹配的getter / setter。

答案 2 :(得分：23)

对我而言，这意味着我“需要在我的maven项目中包含javassist jar”。

答案 3 :(得分：9)

我在我的项目中使用spring 3.0和Hibernate 3.6。我刚才遇到了同样的错误。谷歌搜索此错误消息将我带到此页面。

Funtik在12月1日8点49分的评论帮助我解决了这个问题 -

“这告诉我无法访问javassist。如何将此库包含在项目中？”

所以，我在我的maven pom文件中包含了java assist，如下所示：

<dependency>
    <groupId>javassist</groupId>
    <artifactId>javassist</artifactId>
    <version>3.12.1.GA</version>
</dependency>

这解决了我的问题。谢谢Funtik。

答案 4 :(得分：6)

我知道这是一个古老的问题，很多答案会有所帮助，但就我而言，不幸的是，我遇到了相同的错误，原因有所不同。 （春季启动版本2.0.5.RELEASE）如果使用

  

IntelliJ idea 2018.1.5或更高版本，您将JDK版本设置为JDK 11

发生相同的异常。

更新后
  

JDK版本为8

错误消失了。

答案 5 :(得分：4)

我遇到了同样的问题，并解决了添加此依赖项的问题。

<dependency>
    <groupId>javassist</groupId>
    <artifactId>javassist</artifactId>
    <version>3.12.1.GA</version>
</dependency>

我正在使用hibernate 3.6版本。

答案 6 :(得分：3)

将以下内容添加到pom.xml中，并从hibernate中的asm jars中取出依赖项，并在单独的部分中向asm添加单独的依赖项。我做了同样的事情并且一次性工作。 

    <!-- Hibernate core -->
    <dependency>
      <groupId>org.hibernate</groupId>
      <artifactId>hibernate</artifactId>
      <version>3.2.7.ga</version>

   <exclusions>      
      <exclusion>
         <groupId>asm</groupId> 
           <artifactId>asm</artifactId>
         </exclusion>
      <exclusion>   
          <groupId>asm</groupId>
            <artifactId>asm-attrs</artifactId>
          </exclusion>
      </exclusions>
    </dependency>


    <dependency>
      <groupId>asm</groupId>
      <artifactId>asm</artifactId>
      <version>3.1</version>

答案 7 :(得分：2)

对我而言，这是通过添加显式默认构造函数

来解决的 
public MyClassName (){}

答案 8 :(得分：1)

检查您的Hibernate映射文件* .hbm.xml并检查用于创建getter和setter方法的类。映射文件中的每个属性都应作为填充类中的getter和setter存在。一旦你解决了错误就解决了。

同样通过阅读控制台，您可能会看到提示缺少getter / setter的错误。

希望这会对你有所帮助。

答案 9 :(得分：1)

我知道这篇文章很旧，但是我遇到了同样的问题，我只需将配置从Java 11更改为Java 8即可解决。

答案 10 :(得分：0)

此处与 Jasper Reports Server (JRS) v7.2.0 相同，显然 与 Oracle JDK 11（可能还有 OpenJDK 11）不兼容，但分布式Ora JDK 1.8.0_201运行良好。 这也记录在 JRS 社区论坛中：https://community.jaspersoft.com/questions/1141881/jasper-installation-community-version

答案 11 :(得分：0)

设置“long”类型的id而不是java.lang.Integer。并在您的字段中添加getter和setter。

答案 12 :(得分：0)

我的问题是由于版本冲突引起的。 我通过从springfox中排除字节伙伴依赖性来解决了这个问题

<dependency>
  <groupId>io.springfox</groupId>
  <artifactId>springfox-swagger2</artifactId>
  <version>2.7.0</version>
  <exclusions>
  <exclusion>
    <groupId>net.bytebuddy</groupId>
    <artifactId>byte-buddy</artifactId>
  </exclusion>
  </exclusions>
</dependency>

<dependency>

  <exclusions>
  <exclusion>
    <groupId>net.bytebuddy</groupId>
    <artifactId>byte-buddy</artifactId>
  </exclusion>
</exclusions>
</dependency>

答案 13 :(得分：0)

在我的情况下，我有一个Kotlin类，其中的某些字段未打开，因此生成的Java  设置者和获取者将是最终决定。通过在每个字段中添加$ ./bin/passengercnt <dat/passengers.txt total passengers: 18 关键字来解决该问题。

之前：

open

之后：

open class User(
    var id: String = "",
    var email: String = ""
)

我遇到了同样的例外情况，由于issue with javassist，我排除了powermock。然后我再次添加它，如下所示，但它无法正常工作：

<dependency>
   <groupId>org.powermock</groupId>
   <artifactId>powermock-module-junit4</artifactId>
   <version>1.7.0</version>
   <scope>test</scope>
   <exclusions>
      <exclusion>
         <groupId>org.javassist</groupId>
         <artifactId>javassist</artifactId>
      </exclusion>
   </exclusions>
</dependency>

<dependency>
   <groupId>org.javassist</groupId>
   <artifactId>javassist</artifactId>
   <version>3.20.0-GA</version>
   <scope>test</scope>
</dependency>

最后我发现我必须从<scope>test</scope>依赖项中删除javassist。希望它可以帮到某人。

请同时检查Hibernate Property Name和Id Name。

答案 16 :(得分：0)

在我的案例中，有助于从hibernate中排除javax.transaction.jta依赖：

<dependency>
  <groupId>org.hibernate</groupId>
  <artifactId>hibernate</artifactId>
  <version>3.2.7.ga</version>
  <exclusions>
    <exclusion>
      <groupId>javax.transaction</groupId>
      <artifactId>jta</artifactId>
    </exclusion>
  </exclusions>
</dependency>

答案 17 :(得分：0)

我遇到了类似的问题，经过大量的堆栈溢出和花时间在jar依赖项上，我发现在我的情况下，我有两套asm.jar。我删除了其中一个并且工作正常......

答案 18 :(得分：0)

根据堆栈跟踪：

Caused by: java.lang.NoClassDefFoundError: javassist/util/proxy/ProxyObject at     java.lang.ClassLoader.defineClass1(Native Method)

问题是由“java.lang.NoClassDefFoundError”引起的，所以我认为你应该专注于此。

直接解决方案是添加依赖

<dependency>
    <groupId>javassist</groupId>
    <artifactId>javassist</artifactId>
    <version>3.12.1.GA</version>
</dependency>

到你的pom.xml。

答案 19 :(得分：0)

即使在添加了no-arg构造函数之后我也遇到了同样的错误，然后我发现我错过了几个JAR。我发布这个，这样如果有人得到了我得到的错误，请确保添加了这些JAR在你的lib文件夹中：
