SpringBoot - GemFire - 启动时初始化定位器和端口

Question

我正在使用带有 gemfire 8.2 的 springboot 1.5.2 并在 xml 中配置主机和端口运行良好。相反，我们硬编码需要从云服务器配置中读取的主机和端口的值，并且它无法在 xml 中读取这些值。计划将主机和端口设置从 xml 移动到 java 代码。启动时出现以下错误。

现有的 XML 配置

<gfe:pool id="clientPool" subscription-enabled="true">
        <gfe:locator host="x.x.x.x" port="x" />
    </gfe:pool> 

在spring启动时导入了这个xml。

XML 到 Java 代码

@Configuration
public class GeodeConfig {

    @Resource
    GemFireCache gemfireCache;

    @Bean
    ClientCacheFactoryBean gemfireCache() {
        ClientCacheFactoryBean gemfireCache = new ClientCacheFactoryBean();

        gemfireCache.setClose(true);
        gemfireCache.setCacheXml(new ClassPathResource("gemfirexml.xml"));
        return gemfireCache;
    }

    @Bean
    PoolFactoryBean gemfirePool(
          @Value("${host}") String host,
          @Value("${port}") int port) {
        PoolFactoryBean gemfirePool = new PoolFactoryBean();
        gemfirePool.setName("clientPool");
        gemfirePool.setSubscriptionEnabled(true);
        gemfirePool.setThreadLocalConnections(false);
        gemfirePool.setServers(Collections.singletonList(new ConnectionEndpoint(host, port)));
        return gemfirePool;
    }


}

Answer 1

@Vigneshwaran-

ClientCacheFactoryBean.setCacheXml(:Resource) 用于设置对 GemFire native cache.xml resource 的引用，不是 Spring XML 配置，因此是异常...

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'gemfireCache': FactoryBean threw exception on object creation; nested exception is com.gemstone.gemfire.cache.CacheXmlException: Unknown XML element "beans"

特别是...nested exception is com.gemstone.gemfire.cache.CacheXmlException: Unknown XML element "beans"，特别是...“未知元素'beans'”。

"beans" 显然是一个 Spring XML 配置元素，来自Spring beans namespace。当然，GemFire 的原生 cache.xml 解析器对 Spring XML 配置和命名空间（例如 beans）一无所知。

如果您想将 Spring XML 配置与 Spring 的 JavaConfig 结合使用，请执行以下操作...

@Configuration
@ImportResource("class/path/to/spring/config.xml")
class GeodeConfig {
 ...
}
