如何将其他模块中的类导入Jersey？

Question

我想创建一个包含两个模块的 Java 项目。一个是数据分析模块，另一个是创建restful服务器的模块，这样我就可以远程做数据分析了。结构如下：

├── MyProject
|   ├── Module 1: classA
|   └── Module 2: 
|            └── HelloWorld (resource class)
|            └── MyApplication (configuration class)

在模块 2 中，我使用 Jersey。（我是新手）我使用 glassfish 和 Jersey 来构建它. （我指的是this link）。

我将模块 1 中的 classes 导入到模块二class 中的资源 class

import module1.classA

public class HelloWorld {

    classA a;

    public HelloWorld(){

        classA a = new classA();

    }

    @GET
    @Consumes({MediaType.TEXT_PLAIN})
    @Produces(MediaType.TEXT_PLAIN)
    public String getClichedMessage(@QueryParam("test") String test){

        return a.data_analysis()

    }
}

但是我得到如下异常：

表示没有找到module1中的class。

我想知道如何处理它。如果我实现它的框架是错误的，那么将其他模块导入 Jersey 的正确方法是什么？

Answer 1

为了访问 Module 2 中的 Module 1 资源，您需要将 Module 1 添加到 Module 2 的模块依赖项中。 Select Open Module Settings 在上下文菜单中并在 Dependencies 选项卡中添加模块。
