mybatis的mapper.xml使用parameterType使用的报错
错误在于一个写的get(Long id)的查询方法, 而在Mapper.xml中我定义了这个接收的参数的类型是int类型, 结果就报了如下的错误
1 org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.type.TypeException: Could not set parameters for mapping: ParameterMapping{property='id', mode=IN, javaType=class java.lang.Integer, 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.

它说我的类型不匹配, 然后我看一下报错的提示, 直接定位到上面的地方, 只要把xml中定义的参数类型改成long就好了
