当我使用sql-compenent可以从数据库中检索记录时，Map<String,Object>可以。
<to uri="sql-clsivtrk:{{clsiv_tracker_config_se}}?outputType=SelectOne" />
但是，当我这样定义outputClass时：
<to uri="sql-clsivtrk:{{clsiv_tracker_config_se}}?outputType=SelectOne&outputClass=br.com.rwit.clsi.m2m.rs.model.TrackerConfig" />
我收到错误java.sql.SQLException: Fail to convert to internal representation

您可以显示您的outputClass吗？
在outputType下显示：
将使用者或生产者的输出作为Select List作为Map列表， 或通过以下方式将SelectOne作为单个Java对象：a）如果 查询只有一个列，则该JDBC列对象是 回到。 （例如SELECT COUNT（）FROM PROJECT将返回Long 宾语。 b）如果查询有多个列，则它将返回 该结果的地图。 c）如果设置了outputClass，则它将 通过调用所有，将查询结果转换为Java bean对象 与列名称匹配的设置器。它将假定您的班级有一个 用于创建实例的默认构造函数。 d）如果查询结果 在多行中，它将引发一个非唯一的结果异常。
应该做的一件事情是，列名应该与设置器匹配，并且应该存在一个默认的构造函数。是这样吗？
