在命名空间内使用Spring配置文件(Using Spring profiles inside a namespace)

你不需要知道CXF来回答这个问题。

假设我有下面的使用CXF创建JAXRS服务器的XML声明

<jaxrs:server id="customerService" address="/service1"> <jaxrs:serviceBeans> <ref bean="serviceBean1" /> <ref bean="serviceBean2" /> <ref bean="serviceBean3" /> </jaxrs:serviceBeans> </jaxrs:server>

现在我需要找到一种方法来使用Spring配置文件机制在每个环境中自定义此JAXRS服务器。我可以做一些事情：

但这并不是我想要的，因为我的真实世界的JAXRS服务器比我的例子要复杂一点。

我正在寻找的东西是这样的：

<jaxrs:server id="jaxrsServer" address="/service1"> <jaxrs:serviceBeans> <beans profile="dev"> <ref bean="serviceBean1" /> <ref bean="serviceBean2" /> </beans> <beans profile="dev"> <ref bean="serviceBean2" /> <ref bean="serviceBean3" /> </beans> </jaxrs:serviceBeans> </jaxrs:server>

但它不起作用。

我试图将我的列表创建外部化：

它仍然不起作用，因为CXF名称空间处理程序不会“扁平化”列表，因此它不处理2个serviceBeans对象的列表，而是处理1个ArrayList的列表，这不是由CXF处理的类型。

Spring XML解析试图获得一个列表。我发现在CXF名称空间处理代码中：

if ( "serviceBeans".equals(name) ) { List<?> list = ctx.getDelegate().parseListElement(el, bean.getBeanDefinition()); bean.addPropertyValue(name, list); }

而不是引用一个bean，是不是可以用Spring或其他可以工作的引用“xml声明片段”？

You don't need to know CXF to answer this question.

Suppose I have the following XML declaration which creates a JAXRS server using CXF

<jaxrs:server id="customerService" address="/service1"> <jaxrs:serviceBeans> <ref bean="serviceBean1" /> <ref bean="serviceBean2" /> <ref bean="serviceBean3" /> </jaxrs:serviceBeans> </jaxrs:server>

Now I need to find a way to customize this JAXRS server per environment, using Spring profiles mechanism. I could do something like:

But it is not what I would like to have, because my real-world JAXRS server is a bit more complicated than in my exemple.

What I am looking for is something like that:

<jaxrs:server id="jaxrsServer" address="/service1"> <jaxrs:serviceBeans> <beans profile="dev"> <ref bean="serviceBean1" /> <ref bean="serviceBean2" /> </beans> <beans profile="dev"> <ref bean="serviceBean2" /> <ref bean="serviceBean3" /> </beans> </jaxrs:serviceBeans> </jaxrs:server>

But it doesn't work.

I tried to externalize my list creation:

It still doesn't work because CXF namespace handler does not "flatten" the list, so instead of dealing with a list of 2 serviceBeans objects, it deals with a list of 1 ArrayList, which is not a type handled by CXF.

The Spring XML parsing tries to get a list. I found that in CXF namespace handling code:

if ( "serviceBeans".equals(name) ) { List<?> list = ctx.getDelegate().parseListElement(el, bean.getBeanDefinition()); bean.addPropertyValue(name, list); }

Instead of referencing a bean, isn't it possible to reference a "xml declaration fragment" with Spring or something else that could work?

最满意答案

你有没有尝试过使用别名+配置文件

<jaxrs:server id="jaxrsServer" address="/service1"> <jaxrs:serviceBeans> <ref bean="serviceBeanA" /> <ref bean="serviceBeanB" /> </jaxrs:serviceBeans> </jaxrs:server> <beans profile="profile1"> <alias name="serviceBean1" alias="serviceBeanA"/> <alias name="serviceBean2" alias="serviceBeanB" /> </beans> <beans profile="profile2"> <alias name="serviceBean3" alias="serviceBeanA"/> <alias name="serviceBean4" alias="serviceBeanB" /> </beans>

免责声明：这个答案是一个纯粹的幻想，但评论是有限的 - 我会删除，如果它不会工作

Have you tried using aliases + profiles

<jaxrs:server id="jaxrsServer" address="/service1"> <jaxrs:serviceBeans> <ref bean="serviceBeanA" /> <ref bean="serviceBeanB" /> </jaxrs:serviceBeans> </jaxrs:server> <beans profile="profile1"> <alias name="serviceBean1" alias="serviceBeanA"/> <alias name="serviceBean2" alias="serviceBeanB" /> </beans> <beans profile="profile2"> <alias name="serviceBean3" alias="serviceBeanA"/> <alias name="serviceBean4" alias="serviceBeanB" /> </beans>

disclaimer: this answer is a pure fantasy, but the comments are somewhat limited - I'll remove if it won't work
