java - 如何在 JRuby 中编写此代码？

Question

爪哇：

import java.util.*;
import org.scribe.builder.*;
import org.scribe.builder.api.*;
import org.scribe.model.*;
import org.scribe.oauth.

JRuby：

java_import org.scribe.builder.*;
java_import org.scribe.builder.api.*;
java_import org.scribe.model.*;
java_import org.scribe.oauth.*;

收到此错误 JRuby ：

wrong constant name OrgScribeBuilder*

Answer 1

您需要使用include_package：https ://github.com/jruby/jruby/wiki/JRuby-Reference#importing-a-package-into-a-class-or-module

Answer 2

你应该得到错误NameError: cannot load Java class org.scribe.builder.。Java 类必须以其完整的限定名导入。

require 'java'
require 'scribe-1.3.4.jar'
# you can't use the start import -> java_import 'org.scribe.builder.*'
java_import 'org.scribe.builder.ServiceBuilder'
service = ServiceBuilder.new;

或如@Idan 所写，使用 include_package

require 'java'
require 'scribe-1.3.4.jar'

# use include_package to have an analogue way like in Java -> 'import org.scribe.builder.*'
module Demo
  include_package 'org.scribe.builder'
  service = ServiceBuilder.new;
end
