带有 aws Lambda 的 activejdbc

Question

我无法让 activejdbc 与 aws serverless 一起使用。

我将连接参数添加为 ENV 变量，并且 Base.findAll() 有效，但我无法让模型工作，我收到以下错误

"org.javalite.activejdbc.InitException: you are trying to work with models, but no models are found. Maybe you have no models in project, or you did not instrument the models. It is expected that you have a file activejdbc_models.properties on classpath\n\tat org.javalite.activejdb

我检查了我的 jar 文件，它确实有一个 'activejdbc_models.properties' 文件，并且检测似乎已经工作了。

这条路是死路吗？我应该转向直接jdbc吗？或者我可以让 actveJDBC 与 lambda 一起使用。

更新 在我的一个模型类地址上运行 javap，这是输出

好的，考虑到您来自javap 命令的输出，您的类已被检测。但是，您的构建仍然存在一些问题，因为您似乎正在将非仪器类发布到 AWS Lambda，因此您的例外。我创建了一个非常简单的测试来在 Lambda 中运行 ActiveJDBC：

  @Override
  public String handleRequest(Map<String,String> event, Context context)  {

    context.getLogger().log("Starting to connect...");
    Base.open("org.mariadb.jdbc.Driver", "jdbc:mysql://database-1.xxxxx.us-east-2.rds.amazonaws.com/test", "admin", "xcxxxx");
    context.getLogger().log("connected!!");
//    Base.exec("create database test");
//    Base.exec("CREATE TABLE people (id  int(11) NOT NULL auto_increment PRIMARY KEY, name VARCHAR(56) NOT NULL, last_name VARCHAR(56), dob DATE, graduation_date DATE, created_at DATETIME, updated_at DATETIME) ENGINE=InnoDB DEFAULT CHARSET=utf8");

    context.getLogger().log("Found records  in table: " + Base.count("people"));
    context.getLogger().log("Found records  in table (with model): " + Person.count());
    Base.close();
    context.getLogger().log("Executed and  closed");
    return "Lambda done executing..." ;
  }

当我执行 Lambda 时，CloudWatch 提供了以下日志：

执行模型后记录的行。 如您所见，JavaLite ActiveJDBC 和 AWS Lambda 之间没有冲突。您需要调查您的构建问题。
