spring-aop在苹果硅（M1）上：非法方法名称-编程知识-白鹭情

我的作业项目使用 kotlin spring-boot。

当我尝试should success WHEN setting key is api updatable在 MacBookapple-m1机器上运行具有空间的测验用例时，我发现了这个问题。

例子

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

然后 JVM 抛出包含堆栈跟踪的例外看起来像这样

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

这发生在我的 MacBook m1 机器上，但从未发生在英特尔机器上。

我尝试调查这个问题，然后我发现@Transactional在bean中使用方法时，spring-aop会通过使用方法创建一个代理类java.lang.ClassLoader.defineClass。

我有很多看起来像这样的方法，而且很容易阅读。我可以使用包含space在 m1 机器中运行的方法名称，我该如何修复它？

谢谢你。

环境

JDK 1.8 版 (AArch64)
春季启动 1.5.16
JUnit 4

（我尝试使用 spring-boot2 JUnit5 测验用例名称包含空格进行 POC。但是 bean 中的方法Illegal method name也抛出了。）

uj5u.com热心网友回复：

您可能会遇到Spring 5.1 中修复的Spring 问题 #21674。如果可以的话，您可能想要升级。似乎有一个忽略这些方法的修复程序。这对你来说是否合适，我不知道。

一些背景信息：您的目标方法是事务性的，因此 Spring 尝试为它创建一个 CGLIB 代理。我在一个简单的 Spock (Groovy) 测验中快速验证了 CGLIB 似乎无法正确处理包含空格的方法——可能是因为它根本不知道像 Groovy 和 Kotlin 这样的语言允许这样的事情。这是一个概念证明。我使用了 Groovy 和 Spock，因为我很懒，不想建立 Kotlin 项目。但我希望结果是相同的。

被测Java类：

package de.scrum_master.stackoverflow.q70654015;

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

正在测验的 Groovy 类：

package de.scrum_master.stackoverflow.q70654015

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

Spock 测验创建 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!"
  }
}

第一个测验通过，第二个测验失败：

这与您遇到的错误相同。只要将 Groovy 方法重命名为在 JVM 中合法的名称，测验就会通过。

关于您声称该行为应该取决于硬件或作业系统平台的说法，我不同意。我认为您的运行时环境可能存在差异。你是如何构建和运行你的项目的？Maven，Gradle，还有别的吗？

Update: I have good news for you: I had run my test on JDK 8 and 15 and cglib:cglib-nodep:3.2.6. When upgrading to CGLIB 3.3.0, the test started passing. So you might want to version-manage CGLIB in your Maven POM's <dependencyManagement> section (or whatever is Gradle's equivalent) to that version. Maybe it helps. Please note that some tools might also depend on cglib:cglib, so you want to version-manage that one too. I.e., make sure that you use these versions:

cglib:cglib-nodep:3.3.0
cglib:cglib:3.3.0 (if it is used in your application)

Update 2: I am not a regular Spring user, so I forgot that Spring Core (artifact org.springframework:spring-core) includes its own CGLIB version, relocated to base package name org.springframework.cglib. Please note the package name difference from your stack trace to the original net.sf.cglib for my stand-alone example.

我查了一下，发现自版本以来5.2.0.RELEASE，Spring Core升级到了 CGLIB 3.3.0。因此，如果您可以使用 Spring 5.2.0 或更高版本，那么它很可能适合您。
