休眠org.objectweb.asm.classwriter

Question

当我运行与hibernate一起工作的Java应用程序时出现此错误：

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

我添加了所有罐子的asm

安慰：

当提供的库版本没有所需的类时，就会发生这种情况。 虽然没有一般性的解决方法，但是您可以尝试这种对我有用的方法。

您需要做的就是从休眠中适当排除ASM库，并单独包含它。 似乎很模糊，但请查看工作的pom.xml中的代码段。 这种方法的目的是包括依赖库的更高版本，而项目中的其他第三库可能会需要该库。

对于包括休眠实体管理器，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>

在这里，我明确将冬眠实体管理器中的asm排除在外，在其旁边我分别将其包括在内

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

和属性。 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。
