苹果硅上的spring (M1)：非法方法名称

Question

我的工作项目使用kotlin +spring。

当我试图在MacBook apple-m1计算机上运行一个具有类似于apple-m1的空间的测试用例时，我发现了这个问题。

示例

@Test
@Transactional
fun `should success when setting key is api updatable`()

然后JVM抛出包含堆栈跟踪的异常，如下所示

Caused by: java.lang.ClassFormatError: Illegal method name "should success when setting key is api updatable" in class com/xxx/xxx/web/rest/CompanySettingResourceIntTest$$EnhancerBySpringCGLIB$$f0902682

这种情况发生在我的MacBook m1机器上，但从没有发生在英特尔机器上。

我试图研究这个问题，然后我发现当在bean中使用@Transactional时，spring-aop将使用方法java.lang.ClassLoader.defineClass创建代理类。

我有很多这样的方法，很容易读懂。我是否可以使用包含space的方法名在m1机器中运行，如何修复它？

谢谢。

环境

• JDK版本1.8 (AArch64)
• 弹簧引导1.5.16
• JUnit 4

(我尝试使用spring-boot2+JUnit5 5测试用例来实现POC，用例名称包含空间是可以的。)但是bean中的一个方法也抛出了Illegal method name。)

Answer 1

您可能会碰到在Spring5.1中修复的春季一期#21674。如果这是一个选项，您可能想升级。似乎有一种解决办法忽略了这些方法。如果你不介意的话，我不知道。

一些背景信息:您的目标方法是事务性的，因此Spring试图为它创建一个CGLIB代理。我在一个简单的Spock ( Groovy )测试中很快证实，CGLIB似乎无法正确地处理包含空格的方法，因为它根本不知道Groovy和Kotlin这样的语言允许这样的东西。这里是一个概念的证明。我使用Groovy和Spock，因为我很懒，不想设置Kotlin项目。但我希望结果是一样的。

测试中的Java类：

package de.scrum_master.stackoverflow.q70654015;

public class SampleJava {
  public String greet(String input) {
    return "Hello " + input + "!";
  }
}

测试中的Groovy类：

package de.scrum_master.stackoverflow.q70654015

class SampleGroovy {
  String "say hello to"(String input) {
    "Hello $input!"
  }
}

Spock测试创建CGLIB代理：

package de.scrum_master.stackoverflow.q70654015

import net.sf.cglib.proxy.Enhancer
import net.sf.cglib.proxy.MethodInterceptor
import spock.lang.Specification

class CGLIBProxyTest extends Specification {
  def "create CGLIB proxy for Java class"() {
    given:
    Enhancer enhancer = new Enhancer()
    enhancer.superclass = SampleJava
    enhancer.callback = { obj, method, args, proxy ->
      method.getDeclaringClass() != Object.class && method.getReturnType() == String.class
        ? "Hello cglib!"
        : proxy.invokeSuper(obj, args)
    } as MethodInterceptor

    when:
    SampleJava proxy = enhancer.create()

    then:
    proxy.greet("world") == "Hello cglib!"
  }

  def "create CGLIB proxy for Groovy class with spaces in method name"() {
    given:
    Enhancer enhancer = new Enhancer()
    enhancer.superclass = SampleGroovy
    enhancer.callback = { obj, method, args, proxy ->
      method.getDeclaringClass() != Object.class && method.getReturnType() == String.class
        ? "Hello cglib!"
        : proxy.invokeSuper(obj, args)
    } as MethodInterceptor

    when:
    SampleGroovy proxy = enhancer.create()

    then:
    proxy."say hello to"("world") == "Hello cglib!"
  }
}

第一个测试通过，第二个测试失败：

这是你所经历过的同样的错误。一旦将Groovy方法重命名为JVM中的合法方法，测试就会通过。

关于你说这种行为应该取决于硬件或操作系统平台的说法，我不同意。我认为您的运行时环境可能存在差异。你如何建立和运行你的项目？Maven，Gradle，还有别的事吗？

更新：我有好消息要告诉您:我已经在JDK 8和15以及cglib:cglib-nodep:3.2.6上运行了我的测试。升级到CGLIB 3.3.0时，测试开始通过。因此，您可能希望在Maven POM的<dependencyManagement>部分(或任何与Gradle等效的版本)中管理CGLIB。也许能帮上忙。请注意，有些工具也可能依赖于cglib:cglib，所以您也想要对其进行版本管理。也就是说，确保您使用这些版本：

• cglib:cglib-nodep:3.3.0
• cglib:cglib:3.3.0 (如果它在应用程序中使用)

更新2:我不是一个普通的用户，所以我忘记了Spring (工件org.springframework:spring-core)包含自己的CGLIB版本，重新定位到基本包名org.springframework.cglib。在我的独立示例中，请注意从堆栈跟踪到原始net.sf.cglib的包名差异。

我为您检查并发现，自版本5.2.0.RELEASE以来，Spring是升级到CGLIB 3.3.0。因此，如果您可以使用SpringVersion5.2.0或更近期的版本，那么它很可能适合您。
