当Coldfusion从'jar'文件中调用方法时，未编译的Java程序可以正常工作，但会产生错误？

问题描述 投票：1回答：1

项目：

将JWT转换为已签名的加密JWE

环境：

  1. Windows 10
  2. Jdk1.d
  3. Apache Maven 3.5.4
  4. VSCode 1.25.1包含所有必需的Java扩展
  5. 带有JRE1.8的Adobe Coldfusion 11 Application Server

依赖关系：

  1. 灵气何塞 - 智威汤逊 - 6.0
  2. JSON-智能2.3
  3. ASM-1.0.2

问题：

首先，请理解我是Java的新手，但我对Coldfusion [CFML，如PHP]有很好的理解。

当我从VSCode中运行我的程序时，我得到序列化JWT字符串的预期结果。

当我尝试从'jar'文件中访问该方法时，使用我的服务器端语言Coldfusion [类似于PHP]，我得到一个错误，来自最后一行。

构造函数已成功初始化，并且大多数方法调用都会执行。

我仔细测试了每一行，绝大多数代码在外部调用'JwtSignEncrypt'类的'Encrypt（）'方法时都有效，但是最后一行失败并出现以下错误。

The JWE object must be in an encrypted or decrypted state

我已经正确地将所有必需的库包含在我的'jar'中。当我打包'jar'时，我还需要采取其他措施。我正在使用'pom.xml'文件，有3个依赖项。出于某种原因，当我跑：

nvm package

不包含依赖项。所以，我已经使用'jarsplice'来捆绑依赖项。可以在外部独立地正确访问所有依赖项。

问题：

  1. 当我尝试生成签名加密的JWT时，为什么我在使用Coldfusion调用'.jar'文件中的方法时会收到错误？
  2. 为什么我的依赖项不包含在打包的“.jar”文件中？

更新：

这是我的git回购：

https://bitbucket.org/charlesrobertson/chamika-jwt-app/src/master/

我的java类基于官方文档片段：

https://connect2id.com/products/nimbus-jose-jwt/examples/signed-and-encrypted-jwt

java maven jar coldfusion-11

  1. 当我尝试生成签名加密的JWT时，为什么我在使用Coldfusion调用'.jar'文件中的方法时会收到错误？

我和CF11有同样的错误。问题是try/catch代码基本上吞下了错误，因为CF没有在屏幕上显示e.printStackTrace()的输出。它被发送到默认日志文件。因此，您甚至不会知道发生异常 - 除非您检查CF日志。

错误处理全部取决于应用程序，但我的想法是，如果方法不能对错误做任何有用的事情，也可以让它冒泡并让调用者决定如何处理它。无论如何，一旦我摆脱了所有的try/catch并为所有方法添加了throws XYZException，如下所示：

public String Encrypt(byte[] secretKeyEncoded) throws KeyLengthException, JOSEException {
    // ...
    jweObject.encrypt(new DirectEncrypter(secretKeyEncoded));
    // ...
}

...我可以在屏幕上看到错误消息。无法创建AES / GCM / NoPadding密码：密钥大小非法。这意味着除非安装了Unlimited JCE files，否则无法创建256位密钥（或更高）。解决方案是下载并安装Unlimited JCE文件并重新启动CF.之后，jar工作正常（具有3个依赖项）。

  • 下载java版本的文件。例如，对于java 8 - jce_policy-8.zip
  • 备份local_policy.jar中现有的US_export_policy.jar和<java-home>\lib\security文件
  • 解压缩文件并将新的local_policy.jar和US_export_policy.jar复制到<java-home>\lib\security
  • 重启CF服务器（必填）
  1. 为什么我的依赖项不包含在打包的“.jar”文件中？

Maven不包含依赖项，除非它是specified in the pom.xml，它不适用于此项目。就个人而言，我避免这样做。将所有内容打包到一个大的超级jar中很方便，但是更难以处理依赖项中的版本更改。我只是分别加载相关的罐子。
