ignite有兩種配置方式，一種是基于XML檔案的配置，一種是基于JAVA代碼的配置：
這裡将ignite常用的配置集中羅列出來了，一般建議使用xml配置。
1，基于XML的配置

基于此XML配置啟動ignite節點的方式如下:
@Configuration
public class IgniteConfig {
@Autowired
private IgniteConfiguration igniteCfg;
@Bean
@ConditionalOnMissingBean
public Ignite initIgnite() {
//推薦借助spring bean的方式注入ignite配置資訊,隻需要将配置xml檔案import即可
//啟動類加上注解@ImportResource(locations={"classpath:default-config.xml"})
Ignite ignite = Ignition.start(igniteCfg);
//Ignite ignite = Ignition.start(classpath:default-config.xml)
}
} 2，基于JAVA代碼的配置
......
IgniteConfiguration cfg = new IgniteConfiguration();
cfg.setClientMode(false);
//配置叢集發現
cfg.setDiscoverySpi(new TcpDiscoverySpi().setLocalPort(48500).setLocalPortRange(20)
.setIpFinder(new TcpDiscoveryVmIpFinder().setAddresses(Arrays.asList("127.0.0.1:48500..48520"))));
//基本配置
cfg.setCommunicationSpi(new TcpCommunicationSpi().setLocalPort(48100));
cfg.setDeploymentMode(CONTINUOUS);
cfg.setPeerClassLoadingEnabled(true);
cfg.setPeerClassLoadingLocalClassPathExclude("com.org.ignite.*");
cfg.setIncludeEventTypes(EventType.EVT_TASK_STARTED, EventType.EVT_TASK_FINISHED, EventType.EVT_TASK_FAILED);
cfg.setPublicThreadPoolSize(64);
cfg.setSystemThreadPoolSize(32);
//添加cache配置
List<CacheConfiguration> cacheConf = new ArrayList<>();
CacheConfiguration<String, Integer> conf = new CacheConfiguration<String, Integer>("test")
.setCacheMode(CacheMode.REPLICATED)
.setIndexedTypes(String.class, Integer.class)
.setAtomicityMode(CacheAtomicityMode.ATOMIC)
.setCopyOnRead(false)
.setBackups(1);
cacheConf.add(conf);
cfg.setCacheConfiguration(cacheConf.toArray(new CacheConfiguration[]{}));
//基于java代碼配置啟動
Ignition.start(cfg);
...... 一般建議基于XML配置，spring bean注入，如果确實需要JAVA配置，可以結合XML配置靈活處理。
在ignite叢集中，配置資訊是可以動态傳播的，而如果是修改配置檔案，則需要重新開機節點才可生效，并且如果有些關鍵配置不一緻，也會導緻啟動節點報錯，無法加入叢集。是以最好的做法是，在普通節點中隻配置節點相關配置，以及叢集發現配置，至于變動性最大的緩存cache配置，可以由應用節點配置，這樣便于的集中管控緩存配置。除此之外，使用xml配置，可以保證普通節點與應用節點的配置的一緻性，而不需要單獨再維護一套代碼配置。
