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?

这些都是我正在使用的java文件.它说setter的返回类型与getter不匹配,但我检查了它,并且它在那里是正确的.
