风暴kafka-spout和jdbc-bolt

Question

有人帮我查看我的kafkaspout和jdbcbolt代码！他们不工作！

预览：

我的目的是处理来自kafka，然后storge数据到Mysql的数据！所以，我使用内置的风暴Kafkaspout从kafka获取数据，然后我直接用风暴内置的jdbcbolt将数据存储到MySql ！但他们都不工作！

以下代码是我的拓扑：

        ZkHosts zkHosts = new ZkHosts("dn1:2181,dn2:2181,dn3:2181");

        String topic = "logsinfo";
        String consumer_group_id = "c1";
        SpoutConfig spoutConf = new SpoutConfig(zkHosts, topic, "/brokers/topics", consumer_group_id);
/* #####  */    
        spoutConf.scheme = new SchemeAsMultiScheme(new StringScheme());
        TopologyBuilder topologyBuilder = new TopologyBuilder();

        topologyBuilder.setSpout("kafka2Stormspout",new KafkaSpout(spoutConf),5);

        hikariConfigMap.put("dataSourceClassName","com.mysql.jdbc.jdbc2.optional.MysqlDataSource");  
        hikariConfigMap.put("dataSource.url", "jdbc:mysql://192.168.1.119/logs");  
        hikariConfigMap.put("dataSource.user","root");

        ConnectionProvider connectionProvider = new HikariCPConnectionProvider(hikariConfigMap);  

        String tableName = "logsinfo";

        JdbcMapper myMapper = new MyJDBCMapper(tableName, connectionProvider);

        JdbcInsertBolt userPersistanceBolt = new JdbcInsertBolt(connectionProvider, myMapper)  
                                            .withTableName("logsinfo")

/* #####  */            
        topologyBuilder.setBolt("MySqlBolt", userPersistanceBolt,1);

        Config config = new Config();
        StormSubmitter.submitTopology("WYL Spout from Kakfa", config, topologyBuilder.createTopology());

    }
}

        connectionProvider.prepare();

        this.schemaColumns = client.getColumnSchema(tableName);

        String[] split = tuple.toString().split(" ");
        for (int i = 0; i < schemaColumns.size(); i++) {
            String columnName = schemaColumns.get(i).getColumnName();
            Integer columnSqlType = schemaColumns.get(i).getSqlType();
            if (Util.getJavaType(columnSqlType).equals(String.class)) {
                String value=split[i];
                columns.add(new Column(columnName, value, columnSqlType));
            }
        }
        return columns;
    }

}

这就是我的代码！下图是拓扑运行时截图！ enter image description here

我不知道我哪里错了？
