Caused by: org.apache.ibatis.builder.BuilderException: Error evaluating expression ‘dept.name

Caused by: org.apache.ibatis.builder.BuilderException: Error evaluating expression ‘dept.name != null and dept.name != ‘’’. Cause: org.apache.ibatis.ognl.OgnlException: source is null for getProperty(null, “name”)

注意了，与书写格式无关，是因为有些时候传入对象dept本来就是空值，导致空指针

解决办法：
加上dept ！=null
