使用Spring Boot对于替换Corda服务器给予隐私盐应该是32位的exception
我尝试从Corda Server迁移到Spring Boot.I在Kotlin中提到了Joel的项目（Corda官方），但在尝试使用rpcOps时却得到了这个exception。

private CordaRPCOps rpcOps; @PostConstruct private void init() { System.out.println("RPConnector [host=" + host + ", username=" + username + ", password=" + password + ", rpcPort=" + rpcPort + "]"); NetworkHostAndPort rpcAddress = new NetworkHostAndPort(host, Integer.valueOf(rpcPort)); CordaRPCClient rpcClient = new CordaRPCClient(rpcAddress); CordaRPCConnection rpcConnection = rpcClient.start(username, password); rpcOps = rpcConnection.getProxy(); } public CordaRPCOps getRPCops() { return rpcOps; }
连接成功发生，但是当我尝试使用RPC连接器时出现以下错误：下面是我的控制器。 当我尝试获取所有节点时，出现错误：
@Autowired private RPConnector rpcOps; private final List serviceNames = ImmutableList.of("Controller", "Network Map Service"); @GetMapping("/allnodes") @Produces(MediaType.APPLICATION_JSON) public Map<String, List> getAllNodes() { List nodeInfoSnapshot = rpcOps.getRPCops().networkMapSnapshot(); return ImmutableMap.of("allnodes", nodeInfoSnapshot.stream().map(node -> node.getLegalIdentities().get(0).getName()).filter( name -> !name.equals(rpcOps.getRPCops().nodeInfo().getLegalIdentities().get(0).getName()) && !serviceNames.contains(name.getOrganisation())) .collect(toList())); }
谢谢。
更新错误，有一个空指针exception：

这可以通过清除本地缓存来解决。
