Weld和Java SE [英] Weld and Java SE

问题描述

我是Weld的新手，并且一直试图了解它的概念。我对Spring有一点经验，对Guice没有任何帮助，所以我几乎是DI框架的新手。

I'm new to Weld and have been trying to get my head around it's concepts. I have a little experience with Spring and nothing with Guice, so I'm pretty much a novice with the DI frameworks.

这是一个介绍CDI的教程，但是在Web应用程序的上下文中。我很想知道它在Java SE中是如何工作的。我创建了以下类，但不知道如何在Java SE应用程序中使用DefaultItemDao类（或任何其他替代方法）测试ItemProcessor的execute方法。

Here's a tutorial that introduce CDI, but in the context of web apps. I'm interested to see how this works in Java SE alone. I have created the following classes, but have no idea how to test the ItemProcessor's execute method with the DefaultItemDao class (or any other alternative) in a Java SE app.

这里'是这些类：

public class Item {
    private int value;
    private int limit;

    public Item(int v, int l) {
        value = v;
        limit = l;
    }

    public int getValue() {
        return value;
    }
    public void setValue(int value) {
        this.value = value;
    }
    public int getLimit() {
        return limit;
    }
    public void setLimit(int limit) {
        this.limit = limit;
    }
    @Override
    public String toString() {
        return "Item [value=" + value + ", limit=" + limit + "]";
    }
}


import java.util.List;

public interface ItemDao {
    List<Item> fetchItems();
}

import java.util.ArrayList;
import java.util.List;

public class DefaultItemDao implements ItemDao {

@Override
public List<Item> fetchItems() {
    List<Item> results = new ArrayList<Item>(){{
        add(new Item(1,2));
        add(new Item(2,3));
    }};
    return results;
}

}


import java.util.List;

import javax.inject.Inject;

public class ItemProcessor {
@Inject
private ItemDao itemDao;

public void execute() {
    List<Item> items = itemDao.fetchItems();
    for (Item item : items) {
        System.out.println("Found item: "+item);
    }
}
}

我不知道如何为ItemProcessor类编写测试客户端。有人可以帮我理解如何用CDI写一个吗？

And I have no idea how to write a test client for the ItemProcessor class. Can someone help me understand how to write one with CDI?

谢谢，Kumar
