Question

我使用的是Hazelcast 2.5。最近我们在生产服务器上发现了“APPARENT DEADLOCK”问题。在某处我们发现升级到Hazelcast 3.0或更高版本可以解决问题。现在，当我尝试升级到3.1时，我在ApplicationContext.xml中遇到以下错误，并且它不再识别命名空间“hz”。

applicationContext-hazelcast.xml内容在升级到3.1之前（删除了一些名称空间）

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:cache="http://www.springframework.org/schema/cache"
    xmlns:hz="http://www.hazelcast.com/schema/spring"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd 
        http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache.xsd
        http://www.hazelcast.com/schema/spring http://www.hazelcast.com/schema/spring/hazelcast-spring-2.5.xsd">

升级到3.1（删除一些名称空间）后的applicationContext-hazelcast.xml内容

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:cache="http://www.springframework.org/schema/cache"
    xmlns:hz="http://www.hazelcast.com/schema/spring"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd 
        http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache.xsd
        http://www.hazelcast.com/schema/spring http://www.hazelcast.com/schema/spring/hazelcast-spring-3.1.xsd">

错误讯息：

Multiple annotations found at this line:
    - schema_reference.4: Failed to read schema document 'http://www.hazelcast.com/schema/spring/hazelcast-spring-3.1.xsd', because 1) could not find the document; 2) the document could not be read; 3) 
     the root element of the document is not <xsd:schema>.
    - cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'hz:hazelcast'.

我该怎么做？

你似乎在下载3.1 XSD时遇到问题。当我尝试使用hazelcast-spring-3.1时，我收到了HTTP 403。

当我升级到使用hazelcast-spring-3.2时，一切都适合我，我可以通过Spring Bean获得Hazelcast实例。您是否可以尝试升级到3.2并告诉我这是否适合您。与此同时，我将在github.com/hazelcast中针对3.1问题提出问题。

将Hazelcast从2.5升级到3.1
