Question

在我启动所有项目单元测试之前，每件事情似乎都是完美的。将我的项目从 2.2.1.1 升级到struts 2.3.15.1 后，我收到了以下错误：

java.lang.NoSuchMethodError: org.objectweb.asm.ClassWriter.<init>(Z)V
    at net.sf.cglib.core.DebuggingClassWriter.<init>(DebuggingClassWriter.java:47)
    at net.sf.cglib.core.DefaultGeneratorStrategy.getClassWriter(DefaultGeneratorStrategy.java:30)
    at net.sf.cglib.core.DefaultGeneratorStrategy.generate(DefaultGeneratorStrategy.java:24)

    at net.sf.cglib.core.KeyFactory.create(KeyFactory.java:104)
    at net.sf.cglib.proxy.Enhancer.<clinit>(Enhancer.java:69)

问题实际上是struts 2.3.15.1使用另一个版本的asm框架，它与前一个版本不同。这里是mvn tree的结果

你可以看到struts使用的是asm 3.3，它不是hibernate传递依赖中定义的那个。我的解决方案我从我的struts声明中排除了这种依赖

<dependency>
            <groupId>org.apache.struts</groupId>
            <artifactId>struts2-core</artifactId>
            <version>2.3.15.1</version>
            <exclusions>
                <exclusion>
                    <groupId>asm</groupId>
                    <artifactId>asm</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

问题已经解决，但我现在遇到了新的错误，我无法弄清楚是什么。？

@AleksandrM as Always，谢谢你的合作:) 实际上，在从struts核心传递依赖项中排除 ognl 工件后，问题得以解决。似乎用于编译所有单元测试的版本与用于运行这些单元测试的版本不同。

<dependency>
            <groupId>org.apache.struts</groupId>
            <artifactId>struts2-core</artifactId>
            <version>2.3.15.1</version>
            <exclusions>
                <exclusion>
                    <groupId>asm</groupId>
                    <artifactId>asm</artifactId>
                </exclusion>
                <exclusion>
                    <groupId>ognl</groupId>
                    <artifactId>ognl</artifactId>
                </exclusion>            
            </exclusions>       
        </dependency>
