dubbo异步与一致性hash负载均衡

一致性hash

/**

 public static void setLoadbalance(ServiceConfig serviceConfig) {
 serviceConfig.setLoadbalance("consistenthash");
 MethodConfig methodConfig = new MethodConfig();
 methodConfig.setName("getByName");
 Map<String, String> params = new HashMap<>(10);
 params.put("hash.arguments", "0,1");
 params.put("hash.nodes", "200");
 methodConfig.setParameters(params);        serviceConfig.setMethods(Collections.singletonList(methodConfig));
 }

异步

public static void main(String[] args) throws IOException {
    ApplicationConfig applicationConfig = new ApplicationConfig("client");
    RegistryConfig registryConfig = new RegistryConfig("zookeeper://192.168.150.120:2181");
    ReferenceConfig referenceConfig = new ReferenceConfig();
    referenceConfig.setRegistry(registryConfig);
    referenceConfig.setInterface(UserService.class);
    // referenceConfig.setUrl("dubbo://192.168.21.1:20880/cn.jaminye.base.UserService");
    referenceConfig.setApplication(applicationConfig);
    // referenceConfig.setGroup("jamin");
    setLoadbalance(referenceConfig);
    BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(System.in));
    while (true) {
        if (bufferedReader.readLine().equals("quit")) {
            break;
        }
        UserService userService = (UserService) referenceConfig.get();

        System.out.println(userService.getByName("测试", "12"));
        System.out.println(userService.getByName("212121212", "313dsdas"));
        System.out.println(userService.getByName("1231asdas", "casdas"));
        System.out.println(userService.getByName("12cacas3344D", "12121213122112"));
        System.out.println(userService.getByName("12312adsd", "dasdas"));
        System.out.println(userService.getByName("测试", "12"));

    }
}
