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

Question

我正在使用 Hibernate 开发应用程序，但在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>

还有不包含 getter/setter 的类：

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

我将javassist.jar 包含在类路径中。我不知道是什么问题。请有人帮助我。

谢谢！

我在启动错误时发现。如果我在映射文件中包含属性，则会引发异常。如果我只声明表的 id，则不会抛出异常。可能的原因是什么？

Answer 1

设置“长”类型的 id 而不是 java.lang.Integer。并将 getter 和 setter 添加到您的字段中。

Answer 2

当我遇到这个错误时，修复很简单。我只是缺少一个属性的设置器。确保为所有属性定义匹配的 getter / setter。

Answer 3

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 2012 年 1 月 17 日 8:49 的评论帮助我解决了这个问题-

“这告诉我javassist无法访问。你如何将这个库包含到项目中？”

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

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

这为我解决了这个问题。感谢 Funtik。

Answer 4

我也遇到了同样的问题。

添加了相同的依赖并且它工作了（像这样）：

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

Answer 5

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。一旦你修复，错误就解决了。

另外，通过阅读控制台，您可能会看到提到缺少 getter/setter 的错误。

希望对你有所帮助。

Answer 6

对我来说，这是通过添加显式默认构造函数来解决的

public MyClassName (){}

Answer 7

此问题是由于 name="iSetPointId" 使“i”大写和相应的模型类更改而产生的。

Answer 8

在我的例子中，我有一个 isSomething() boolean getter 并得到了这个错误。

我通过使用 JPA @Transient 批注对方法进行批注来解决它，并在 this SO question 的答案中找到确认，因此告诉提供者不要保留该属性。

Answer 9

即使在添加无参数构造函数后我也遇到了同样的错误，然后我发现我缺少几个 JAR。我发布这个是为了如果有人像我一样遇到错误，请确保你已经添加了这些 JAR在你的 lib 文件夹中：

Answer 10

将以下内容添加到您的pom.xml 并从休眠中的asm jar 中取出依赖项，并在单独的部分中将单独的依赖项添加到asm。我也做了同样的事情，而且一次就奏效了。

    <!-- 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>

Answer 11

根据堆栈跟踪：

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

这个问题是由“java.lang.NoClassDefFoundError”引起的，所以我认为你应该关注这个。

直接的解决方法是添加依赖

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

到你的 pom.xml。

Answer 12

我遇到了类似的问题，在经历了很多关于堆栈溢出和花时间处理 jar 依赖项之后，我发现在我的情况下，我有两组 asm.jar。我删除了其中一个，它工作正常......

Answer 13

我遇到了同样的问题并通过添加此依赖项解决了它。

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

我使用的是休眠 3.6 版本。

Answer 14

在我的情况下，有助于从休眠中排除 javax.transaction.jta 依赖项：

<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>

Answer 15

请同时检查 Hibernate 属性名称和 Id 名称。

Answer 16

我有同样的例外，我排除了javassist，因为它的issue withpowermock。然后我再次添加它，如下所示，但它不起作用：

<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 javassist 依赖项中删除 <scope>test</scope>。希望它可以帮助某人。

Answer 17

我知道这是一个老问题，很多答案很有帮助，但就我而言，不幸的是，我遇到了同样的错误，原因不同。 (Spring boot 2.0.5.RELEASE) 如果你使用的是

IntelliJ IDEA 2018.1.5 或以上且你设置JDK版本为JDK 11

发生了同样的异常。更新后

JDK 版本为 8

错误消失了。

Answer 18

在我的情况下，我有一个 Kotlin 类，其中一些字段未打开，因此生成的 Java setter 和 getter 将是最终的。通过在每个字段中添加 open 关键字来解决它。

之前：

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

之后：

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

Answer 19

我的问题是由于版本冲突。 我通过从 springfox 中排除 byte-buddy 依赖解决了这个问题

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