如何將其他模塊中的類導入到澤西島？

Question

我想用兩個模塊創建一個Java項目。一個是用於數據分析的模塊，另一個是用於創建寧靜服務器的模塊，以便我可以遠程執行數據分析。結構如下：

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

在模塊2我使用澤西（我是一個綠色的手就可以了），而且我用GlassFish的和新澤西建立它。 （我指的是this link）。

我導入模塊1類的資源類模塊有兩個

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() 

    } 
} 

但是我得到一個例外如下：

這表明，在模塊1類未找到。

我想知道如何處理它。如果我的框架實現它是錯誤的，那麼將其他模塊導入澤西島的正確方法是什麼？

Answer 1

要訪問Module 2中的Module 1資源，您需要將Module 1添加到Module 2的模塊相關性中。在上下文菜單中選擇Open Module Settings，然後在Dependencies選項卡中添加該模塊。
