我有一个grails项目，我想在其中配置Hazelcast。但是我做不到。我已经下载了hazelcast并添加到lib文件夹中。然后我尝试在资源文件中初始化

hazelcastConfigurer(MethodInvokingFactoryBean){ 
        targetClass = "com.hazelcast.core.Hazelcast" 
        targetMethod = "init" 
        Config hazelcastConfig = new Config("hazelcast.xml") 
        arguments = hazelcastConfig 
} 

它只是不编译而引发错误

是否有任何博客或网站可以帮助我在Grails项目中进行配置？

请您参考如下方法:

这是我在Grails 2.1.2应用程序中配置Hazelcast 3.2以便与Spring缓存批注一起使用的方式:

BuildConfig.groovy

dependencies { 
    ... 
 
    compile "com.hazelcast:hazelcast:3.2" 
    compile "com.hazelcast:hazelcast-spring:3.2" 
} 

Hazelcast实例配置， src/java/spring/hazelcast.xml:

<beans xmlns="http://www.springframework.org/schema/beans" 
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
       xmlns:context="http://www.springframework.org/schema/context" 
       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/context 
                http://www.springframework.org/schema/context/spring-context-3.1.xsd 
                http://www.hazelcast.com/schema/spring 
                http://www.hazelcast.com/schema/spring/hazelcast-spring-3.2.xsd"> 
 
    <hz:hazelcast id="hazelcastInstance"> 
        <hz:config> 
 
            <hz:map name="myCache" 
                    backup-count="0" 
                    in-memory-format="OBJECT" 
                    > 
            </hz:map> 
 
        </hz:config> 
    </hz:hazelcast> 
 
</beans> 

启用S​​pring缓存注释 src/java/spring/spring-cache.xml:

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
       xmlns:cache="http://www.springframework.org/schema/cache" 
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd 
        http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache.xsd"> 
 
    <cache:annotation-driven/> 
 
</beans> 

全部连接在一起-Spring缓存注释所使用的缓存管理器bean是使用Hazelcast实例bean grails-app/conf/spring/resources.groovy配置的:

beans = {           
 
        importBeans('classpath:/spring/spring-cache.xml')               
        importBeans('classpath:/spring/hazelcast.xml') 
 
        cacheManager(com.hazelcast.spring.cache.HazelcastCacheManager, ref('hazelcastInstance'))                        
} 

现在，您可以将Spring缓存注释(如 @Cacheable和 @CacheEvict)与Hazelcast缓存一起使用:

    @Cacheable(value = 'myCache') 
    SomethingDto getSomethingDto(Long id) { 
        SomethingDto dto = convertToSomethingDto(Something.get(id)) 
        return dto 
    } 

我通常将域对象转换为DTO，因为如果懒惰地提取普通域对象的某些属性，则将其存储到缓存中可能会引起问题。

一些注意事项:

我将Spring XML文件放入src/java中，因为在grails-app/conf/spring中在生产中找不到它们，请参见Load spring beans from custom groovy files in grails app

您可以使用resources.groovy中的环境块来实现每个环境的Hazelcast配置。我使用了它，但是为了简单起见，我没有在这里发布它。
