2、解决方法
1）使用了Google的protobuffer；
2）定位是序列化的问题；
at com.xs.fun.base.proto.service.WorldChannelProtoBuffer$ProclamationInfoProto$Builder.setContent(WorldChannelProtoBuffer.java:2859)
at com.xs.fun.base.bo.proclamation.ProclamationInfo.copyTo( ProclamationInfo.java:44)
at com.xs.fun.base.bo.proclamation.ProclamationInfoList.copyTo （ ProclamationInfoList.java:30)
at com.xs.fun.base.dao.redis.ProclamationRepo.saveProclamationNotice( ProclamationRepo.java:20)
at com.xs.fun.hall.service.ProclamationService.saveProclamationNotice( ProclamationService.java:22)
at org.apache.jsp.admin.proclamationtManager.sendProclamation_jsp._jspService( sendProclamation_jsp.java:184)
3）经过测试，是content为null，
if(Split.equals("1")){
proclamationInfo_robotClient.setContent("{c=100,111,11}{"+title2+"}{/}"
+"{c=100,111,11}{"+content2+"}{/}"
+"{c=255,239,28}{"+startTime+"}{/}"
+"{c=255,239,28}{"+endTime+"}{/}");
proclamationInfo_robotClient.setPostTime(Long.parseLong(startTime));
proclamationInfo_robotClient.setType(3);
proclamationInfo_robotClient.setProclamationId(Integer.parseInt(id));
proclamationInfo_robotClient.setPackageInfo(Integer.parseInt(Split));
proclamationInfo_robotClient.setProclamationReadState(ProclamationState.NEW.getCode());
accountService.notifyLogonPlayerWorldChannelMsg(proclamationInfo_robotClient.getType()
,(long)proclamationInfo_robotClient.getPostTime()
,"NEW_PROCLAMATION"
,Integer.parseInt(Split));
System.out.println("1");
}
4）继续找，原因找到了；就是逻辑出错了，将保存的步骤放在了if里头，导致没有遍历别的，但是保存了，空数据结构就会发生报错。如下所示为错的；
wrong：
if(type.equals("new")){
String[] proclamationChannelSplit = packageId.split(",");
System.out.println("0.size:"+proclamationChannelSplit.length);
for(String Split : proclamationChannelSplit){
if(Split.equals("-1")){
//四个WorldChannelInfo组合为list表，存储到redis
proclamationInfoList.addProclamationInfo(proclamationInfo_unknowClient);
proclamationInfoList.addProclamationInfo(proclamationInfo_devClient);
proclamationInfoList.addProclamationInfo(proclamationInfo_robotClient);
proclamationInfoList.addProclamationInfo(proclamationInfo_hanyanClient);
proclamationService.saveProclamationInfoList(proclamationInfoList);
System.out.println("** ProclamationInfoList: "+proclamationService.getProclamationNotice());
}
if(Split.equals("2")){
}
if(Split.equals("1")){
}
if(Split.equals("19588")){
}
}
}else if(type.equals("old")){ //old,当前无需发送公告
accountService.notifyLogonPlayerWorldChannelMsg(3,0l,"NO_PROCLAMATION",-11);
System.out.println("** no procalmation");
}
correct：
if(type.equals("new")){
String[] proclamationChannelSplit = packageId.split(",");
System.out.println("0.size:"+proclamationChannelSplit.length);
for(String Split : proclamationChannelSplit){
if(Split.equals("-1")){
}
if(Split.equals("2")){
}
if(Split.equals("1")){
}
if(Split.equals("19588")){
}
}
}else if(type.equals("old")){ //old,当前无需发送公告
accountService.notifyLogonPlayerWorldChannelMsg(3,0l,"NO_PROCLAMATION",-11);
System.out.println("** no procalmation");
}
//四个WorldChannelInfo组合为list表，存储到redis
proclamationInfoList.addProclamationInfo(proclamationInfo_unknowClient);
proclamationInfoList.addProclamationInfo(proclamationInfo_devClient);
proclamationInfoList.addProclamationInfo(proclamationInfo_robotClient);
proclamationInfoList.addProclamationInfo(proclamationInfo_hanyanClient);
proclamationService.saveProclamationInfoList(proclamationInfoList);
System.out.println("** ProclamationInfoList: "+proclamationService.getProclamationNotice());
