ignite有两种配置方式，一种是基于XML文件的配置，一种是基于JAVA代码的配置：
这里将ignite常用的配置集中罗列出来了，一般建议使用xml配置。
1，基于XML的配置

基于此XML配置启动ignite节点的方式如下:
@Configuration
public class IgniteConfig {
@Autowired
private IgniteConfiguration igniteCfg;
@Bean
@ConditionalOnMissingBean
public Ignite initIgnite() {
//推荐借助spring bean的方式注入ignite配置信息,只需要将配置xml文件import即可
//启动类加上注解@ImportResource(locations={"classpath:default-config.xml"})
Ignite ignite = Ignition.start(igniteCfg);
//Ignite ignite = Ignition.start(classpath:default-config.xml)
}
}
2，基于JAVA代码的配置
......
IgniteConfiguration cfg = new IgniteConfiguration();
cfg.setClientMode(false);
//配置集群发现
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代码配置启动
Ignition.start(cfg);
......
一般建议基于XML配置，spring bean注入，如果确实需要JAVA配置，可以结合XML配置灵活处理。
在ignite集群中，配置信息是可以动态传播的，而如果是修改配置文件，则需要重启节点才可生效，并且如果有些关键配置不一致，也会导致启动节点报错，无法加入集群。所以最好的做法是，在普通节点中只配置节点相关配置，以及集群发现配置，至于变动性最大的缓存cache配置，可以由应用节点配置，这样便于的集中管控缓存配置。除此之外，使用xml配置，可以保证普通节点与应用节点的配置的一致性，而不需要单独再维护一套代码配置。
