WritableByteChannel channel 为null

使用版本为1.0.26 CanalConnector connector = CanalConnectors.newSingleConnector(new InetSocketAddress(ip, 11111), destination,"","");

1.在创建CanalConnector 对象之后发现channel 为null不知道是什么问题

2.mysql的账号，也是根据教程的语句直接生成的

3.server也启动了

start cmd : java -Xms128m -Xmx512m -XX:PermSize=128m -Djava.awt.headless=true -Djava.net.preferIPv4Stack=true -Dapplication.codeset=UTF-8 -Dfile.encoding=UTF-8 -server -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,address=9099,server=y,suspend=n -DappName=otter-canal -Dlogback.configurationFile="E:\canal-dep\bin..\conf\logback.xml" -Dcanal.conf="E:\canal-dep\bin..\conf\canal.properties" -classpath "E:\canal-dep\bin..\conf..\lib*;E:\canal-dep\bin..\conf" java -Xms128m -Xmx512m -XX:PermSize=128m -Djava.awt.headless=true -Djava.net.preferIPv4Stack=true -Dapplication.codeset=UTF-8 -Dfile.encoding=UTF-8 -server -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,address=9099,server=y,suspend=n -DappName=otter-canal -Dlogback.configurationFile="E:\canal-dep\bin..\conf\logback.xml" -Dcanal.conf="E:\canal-dep\bin..\conf\canal.properties" -classpath "E:\canal-dep\bin..\conf..\lib*;E:\canal-dep\bin..\conf" com.alibaba.otter.canal.deployer.CanalLauncher Java HotSpot(TM) 64-Bit Server VM warning: ignoring option PermSize=128m; support was removed in 8.0 Listening for transport dt_socket at address: 9099 2018-05-17 15:17:09.947 [main] WARN o.s.beans.GenericTypeAwarePropertyDescriptor - Invalid JavaBean property 'connectionCharset' being accessed!

运行canal.example-1.0.26-SNAPSHOT 闪退
