Question

当我使用hibernate运行我的java应用程序时出现此错误：

java.lang.NoSuchMethodError：org.objectweb.asm.ClassWriter

我添加了所有的asm

罐子

当提供的库版本没有所需的类时，会发生这种情况。虽然没有一般的解决办法，但你可以尝试这种方法对我有用。

您需要做的就是从hibernate中正确排除ASM库并单独包含它。看起来模糊，但看看工作pom.xml中的片段。这种方法背后的意图是包含一个更新版本的依赖库，这可能是项目中其他第三个库所需要的。

包含hibernate实体管理器我正在使用以下代码。

    <dependency>
     <groupId>org.hibernate</groupId>
     <artifactId>hibernate-entitymanager</artifactId>
     <version>${hibernate.version}</version>
    <exclusions>
        <exclusion>
         <groupId>asm</groupId>
         <artifactId>asm</artifactId>
        </exclusion>
      </exclusions>
    </dependency>

这里我明确地将hm从hibernate-entity manager include中排除，然后我将它单独包含在内

    <dependency>
      <groupId>asm</groupId>
      <artifactId>asm</artifactId>
      <version>${asm.version}</version>
    </dependency>

和属性是。这些版本选择在最新项目中对我有用。

    <properties>
            <hibernate.version>3.6.0.Final</hibernate.version>
            <asm.version>3.3</asm.version>
    </properties>

希望，这可以解决您的问题。

hibernate org.objectweb.asm.classwriter
