That's because there's no such thing as <code>&lt;array&gt;</code>, there's only <code>&lt;list&gt;</code>.

The good news is that Spring will auto-convert between lists and arrays as required, so defined your array as a <code>&lt;list&gt;</code>, and Spring will be coerce it into an array for you.

This should work:

<pre><code>&lt;bean id="googleGeocodingService" class="geocoding.GoogleGeocodingService"&gt;
 &lt;constructor-arg ref="proxy" /&gt;
 &lt;constructor-arg value="" /&gt;
&lt;/bean&gt;

&lt;bean id="geocodingService" class="geocoding.RandomGeocodingService"&gt;
 &lt;constructor-arg&gt;
 &lt;list&gt;
 &lt;ref bean="googleGeocodingService"/&gt;
 &lt;/list&gt;
 &lt;/constructor-arg&gt;
&lt;/bean&gt;
</code></pre>

Spring will also coerce a single bean into a list, if required:

<pre><code>&lt;bean id="geocodingService" class="geocoding.RandomGeocodingService"&gt;
 &lt;constructor-arg&gt;
 &lt;ref bean="googleGeocodingService"/&gt;
 &lt;/constructor-arg&gt;
&lt;/bean&gt;
</code></pre>

Spring can automatically convert a list into an array[]

I'm actually using <code>&lt;array&gt;</code> tag to inject an array of objects into a bean and it works.
Take a look at the following code...
<pre><code> &lt;bean id=&quot;song1&quot; class=&quot;mx.com.company.songs.Song&quot;&gt;
 &lt;property name=&quot;name&quot; value=&quot;Have you ever seen the rain?&quot;/&gt; 
 &lt;/bean&gt;
 
 &lt;bean id=&quot;song2&quot; class=&quot;mx.com.company.songs.Song&quot;&gt;
 &lt;property name=&quot;name&quot; value=&quot;La bamba&quot;/&gt; 
 &lt;/bean&gt;

 &lt;bean id=&quot;guitarPlayer&quot; class=&quot;mx.com.company.musician.GuitarPlayer&quot;&gt;
 &lt;property name=&quot;songs&quot;&gt;
 &lt;array&gt;
 &lt;ref bean=&quot;song1&quot;/&gt;
 &lt;ref bean=&quot;song2&quot;/&gt;
 &lt;/array&gt;
 &lt;/property&gt;
 &lt;/bean&gt; 
</code></pre>

I'm trying to create an array of objects in a Spring context file so I can inject it to a constructor that's declared like this:

<pre><code>public RandomGeocodingService(GeocodingService... services) { }
</code></pre>

I'm trying to use the <code>&lt;array&gt;</code> tag:

<pre><code>&lt;bean id="googleGeocodingService" class="geocoding.GoogleGeocodingService"&gt;
 &lt;constructor-arg ref="proxy" /&gt;
 &lt;constructor-arg value="" /&gt;
&lt;/bean&gt;

&lt;bean id="geocodingService" class="geocoding.RandomGeocodingService"&gt;
 &lt;constructor-arg&gt;
 &lt;array value-type="geocoding.GeocodingService"&gt;
 &lt;!-- How do I reference the google geocoding service here? --&gt;
 &lt;/array&gt;
 &lt;/constructor-arg&gt;
&lt;/bean&gt;
</code></pre>

I haven't been able to find an example or something in the in the documentation on how to do this. Also, you have any suggestions for a better way of acheiving what I'm trying to do, please let me know :).

Declaring an array of objects in a Spring bean context

我试图在Spring上下文文件中创建一个对象数组，这样我就可以将其注入到如下声明的构造函数中：public RandomGeocodingService(GeocodingService... services) { }我正在尝试使用<array>标记：<bean id="googleGeocodingService"...
