点燃java.lang.ClassNotFoundException：对等加载类

时间：2016-11-09 05:16:55

标签： ignite

当我运行下面的代码时，我得到了＃34;无法对等加载类＆＃34;。

String objectIds = "1vxzn3ifggm4o,1a47fmqipb1u3,z56f5kkwlfk3,tths3z5k5l38,79lzqlrd4cg6";
for (String did : objectIds.split(",")) {
      calls.add(() -> {
           TLabObject object = RepositoryDao.getObject(did);
           System.out.println(">>> " + did + " on node = " + ignite.cluster().localNode().id());
           return object;
       });
}
Collection< TLabObject > res = ignite.compute(rmts).call(calls);

isPeerClassLoadingEnabled设置为true deployMode = SHARED

我们将不胜感激。

  

更多详细信息：

  • 我在IDE中使用junit测试用例运行此代码。
  • 服务器端是活动的，测试用例setClientMode（true）。

我试图打包项目并在终端中运行它，我得到了同样的异常。抛出异常后，客户端和服务器不会退出终端。服务器端日志显示客户端和服务器仍然存在：

  

[11:04:07]拓扑快照[ver = 5，servers = 1，clients = 1，CPUs = 4，   堆= 2.0GB

BTW：我发现如果依赖树是复杂的对等加载类失败了！在这种情况下，依赖深度为4 但是，当依赖深度= 2时，它可以工作

答案 0 :(得分：0)

服务器上出现异常后会出现此消息：

[10:20:37] Topology snapshot [ver=57, servers=1, clients=0, CPUs=4, heap=1.0GB]

这实际上意味着客户端由于某种原因而离开，因此服务器无法从中请求该类。检查客户端日志以找出原因。
