Question

我有以下课程：

package models;

public class Test extends activejdbc.Model
{
}

：和：

import activejdbc.*;
import models.Test;

public class ActiveJdbc
{
    public static void main(String args [])  throws Exception
    {
        System.out.println("starting...");
        test();
    }


    public static void test() throws Exception
    {
        activejdbc.Base.open("org.h2.Driver", "jdbc:h2:tcp://localhost/~/test", "sa", "");

        models.Test t = models.Test.findFirst("id = ??",1);
        String s = t.get("name").toString();
        System.out.println(s);
    }

}

：但是当我用：

运行它时

java -cp .;../lib/h2.jar;../lib/activejdbc.jar;../lib/slf4j-simple.jar;../lib/javalite.jar ActiveJdbc

：我收到错误：

starting...
Exception in thread "main" activejdbc.DBException: failed to determine Model class name, are you sure models have been instrumented?
        at activejdbc.Model$ClassGetter.getClassName(Model.java:1577)

        at ActiveJdbc.main(ActiveJdbc.java:9)
Caused by: java.lang.RuntimeException: failed to determine Model class name, are you sure models have been instrumented?

：有人可以对此有所了解吗？

Answer 1

我已经弄明白了。你需要先运行：

java -DoutputDirectory =。 -cp .; activejdbc-instrumentation.jar; javassist.jar; activejdbc.jar; activejdbc.instrumentation.Main

无法使activejdbc正常工作？
