ibatis实体类有构造方法resultClass必须和构造方法参数一致否则报错(九宫格抽奖遇到的问题)
2.spring 和 dubbo包冲突

###加上这个就对了 <exclusions> <exclusion> <groupId>org.springframework</groupId> <artifactId>spring</artifactId> </exclusion> </exclusions> </dependency>
3.shell报错
原因是通过windows上传的脚本 是dos编辑的 在Linux中vim sh文件 :set ff可以查看文件格式为dos 修改 set ff=unix 保存之后再执行就正常了
4.zookeeper启动报错

由于以前服务器意外关闭，现在重启服务器 在启动zkServer.sh start的时候 只能启动两台第三台始终启动不了
解决办法:到data目录下 删除version-2 启动成功
