环境启动正常，登录时报错key is null

jinshuqishi2010

前后台都启动成功，进入登录页面输入用户名、密码和验证码后出现“操作失败”的提示

同时还有“nested exception is org.apache.ibatis.builder.BuilderException: Error evaluating expression 'ew.sqlSegment != null and ew.sqlSegment != '' and ew.nonEmptyOfNormal'. Cause: org.apache.ibatis.ognl.OgnlException: sqlSegment [java.lang.NullPointerException: Cannot invoke "Object.hashCode()" because "key" is null]”

请问这个怎么解决....

下为后端的报告：

问题已解决

在jeecg-boot-base-common/pom.xml中修改修改mybatis-plus-boot-starter的version。改成3.4.0即可。

原因可能是mybatis-plus版本问题？

修改后代码截图：

liu398906114

我也是这个问题 但是我在idea上面没有问题只是在eclipse上碰到这个问题了  我是把版本指定去掉了就好了
