hibernate org.objectweb.asm.classwriter

Question

当我运行我使用 hibernate 的 java 应用程序时出现此错误：

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

和我添加了 asm

控制台的所有 jars:

当提供的库版本不具有所需的类时，就会发生这种情况。虽然没有通用的修复方法，但您可以尝试使用对我有用的方法。

您需要做的就是从 hibernate 中正确排除 ASM 库并单独包含它。看起来很模糊，但看一下工作 pom.xml 中的片段。这种方法背后的目的是包含项目中其他一些第三个库可能需要的更高版本的依赖库。

为了包含休眠实体管理器，我使用以下代码。

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

在这里，我明确地将 asm 从 hibernate-entity manager 包含中排除，并在其旁边单独包含它

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

，并且属性是。这些版本选择在最新的项目中对我有用。

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

希望这能解决您的问题。
