如何调用驻留在不同项目中的方法？

Question

我在Eclipse工作空间中有两个单独的项目是相同的，但是两个项目不同。 假设有两个项目A和B，我已经调用了一个类，假设Test.java具有项目b的主要方法和一个简单的显示方法，而我需要从项目B中调用。在主方法中，我正在调用Test.java类的显示方法。

并假设我在项目A中有另一个类Execute.java ，所以我需要从项目B到Execute.java类中的项目A的Execute.java类，我该怎么做？

任何建议将不胜感激

            //invoke run() - this will run your class.
            //myTestNG.run();




    }
    public static void main(String args[]) throws IOException
    {
        TestNGCreator testDriver = new TestNGCreator();
        testDriver.runTestNGTest();
    }
}

所以我需要调用main方法。

Answer 1

您可以按照以下步骤进行操作。

1. 生成第一个项目并创建jar
2. 右键单击第二个项目->构建路径->配置构建路径->库->添加外部Jar
3. 使用第一个项目中的课程

要么

如果要从任何Web服务发送/接收数据，请以REST API的方式公开您的方法，以使Web服务可以接受它。

您可以使用Apache HttpComponents将您的方法公开给Web服务，请找到以下示例代码。

CloseableHttpClient client = HttpClients.custom().setDefaultRequestConfig(config)
                    .disableContentCompression().setSSLSocketFactory(sslsf).build();

HttpPost postRequest = new HttpPost(url);
client.execute(postRequest);

Answer 2

如果您不使用Maven或Gradle，则可以执行以下步骤以包含项目：

属性->构建路径->项目->添加，添加所需的项目。
