mybatis使用selectByPrimaryKey出錯

mybatis使用selectByPrimaryKey查詢時須要主鍵是String類型的，所以須要將表對應的實體類中的類型改爲String不能爲其它類型

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. Cause: java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Integer
