Mybatis报错解决

Caused by: org.apache.ibatis.type.TypeException: Could not set parameters for mapping: ParameterMapping{property='input', mode=IN, javaType=class java.lang.String, jdbcType=null, numericScale=null, resultMapId='null', jdbcTypeName='null', expression='null'}. 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.sql.SQLException: No operations allowed after statement closed.

解决:mybatis SQL语句指定数据类型，比如：#{lala,jdbcType=VARCHAR}

原因:MyBatis 插入空值时，需要指定JdbcType 
mybatis insert,update空值报空值异常，但是在pl/sql不会提示错误，主要原因是mybatis无法进行转换，
