1.分布式服务注入为NULL,原因为DUBBO扫描位置不对

其他原因
服务上没有加注解@Service或者导入的时spring的注解,不是阿里的
Reference不是阿里的注解

原因:
在该位置没有pagehelper引用,将对应坐标引入即可
将坐标因如可能引发其他问题,见第3个问题

3.java.lang.NoClassDefFoundError: org/apache/ibatis/session/RowBounds

该异常是引入类pagehelper之后未引入mybatis所致,引入相应的坐标即可

4.Caused by: org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException: Expected mime type application/octet-stream but got text/html.image.png

在schema.xml文件配置了IK Analyzer 后显示找不到核心
原因:
IK Analyzer所需要的jar包放错了位置,没有方法到solr的lib目录下,而是放在了tomcat的lib目录下.
如果有错误找到可以在tomcat服务器的lib目录下放log4j.properties文件打印日志

原因是在拼接租户信息的时候需要在request中获取用户token然后获取用户信息.
由于查询数据库的操作不是用户发起的,而是项目启动成功后自动发起的.索所以不存在request信息,故报错
