Question

我创建了一个名为Configuration.java的自定义类，我希望将它放入我的Storm拓扑中的Config对象中。当我尝试拓扑时，我不断收到错误：

java.lang.IllegalArgumentException: Topology conf is not json-serializable

这是我的代码，它试图将Configuration对象放入Config

public static Config loadConf(String resource) {

        Configuration _epconf = null;
        Yaml yaml = new Yaml();

        Config conf = new Config();
        conf.registerSerialization(Configuration.class);  //register the Configuration class 

        try {

           //load the yaml file into the Configuration pojo
           _epconf = (Configuration)yaml.loadAs(new InputStreamReader(new FileInputStream(resource)), Configuration.class);

        } catch (FileNotFoundException e) {
            Log.error("Configuration file does not exist : " + resource);
            System.err.println("Conf file does not exist : " + resource);
            System.exit(-1);
        } catch (YAMLException e ) {
            Log.error("Error parsing YAML file for configuration : " + resource + "\n" + e.getMessage());
            System.err.println("Error parsing YAML file for configuration : " + resource);
            System.exit(-1);
        }

        //verify object is not empty
        if (_epconf == null) {
            Log.error("Empty configuration object created from : " + resource );
            System.err.println("Empty configuration object created from : " + resource);
            System.exit(-1);
        }

        conf.put("epconf", _epconf);  //add the Configuration to the Config object

        return conf;
    }

我认为问题在于我没有正确注册我的班级进行序列化。我怀疑conf.registerSerialization（Configuration.class）并不完全正确，但是我无法理解风暴主页上的文档要求的内容。

将自定义类对象添加到Apache Storm Config
