java – 设置属性值时出错;嵌套异常是org.springframework.bean

我试图使用Spring实用程序ResultSetExtractor从MySQL数据库获取数据,但我得到以下异常：

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'edao' defined in class path resource [applicationContext2.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'jdbcTemplate' of bean class [org.resultset.EmployeeDao]: Bean property 'jdbcTemplate' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?
