使用 aws Lambda 的 activejdbc

如何解决使用 aws Lambda 的 activejdbc

我无法让 activejdbc 与 aws serverless 一起工作。

我添加了我的连接参数作为 ENV 变量并且 Base.findAll() 工作，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，并且检测似乎已经起作用了。

这条路是死路吗？我应该直接转移到 jdbc 吗？或者我可以让 actveJDBC 与 lambda 一起工作。

更新 在我的模型类地址之一上运行 javap，这是输出

解决方法

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，因为您似乎将非检测类发布到 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。您需要调查构建的问题。
