Mybatis Exception Date cannot be cast to String

org.apache.ibatis.type.TypeException: 


最重要是这个提示信息：
Mybatis 不能完成参数映射


Could not set parameters for mapping: 


这个参数是cffDate

ParameterMapping{property='cffDate', 
mode=IN, javaType=class java.lang.String, 
jdbcType=null, numericScale=null, 
resultMapId='null', jdbcTypeName='null', 
expression='null'}. 


原因是类型转换异常

Cause: org.apache.ibatis.type.TypeException: 

Error setting non null for parameter 

#1 with JdbcType null . 

Try setting a different JdbcType for this parameter 

or 

a different configuration property. Cause: java.lang.ClassCastException: 


异常时不能把Date 转换成String

class java.util.Date cannot be cast to class java.lang.String 


(java.util.Date and java.lang.String are 

in module java.base of loader 'bootstrap')
