我試圖使用Spring實(shí)用程序ResultSetExtractor從MySQL數(shù)據(jù)庫(kù)獲取數(shù)據(jù),但我得到以下異常：

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?

這些都是我正在使用的java文件.它說(shuō)setter的返回類(lèi)型與getter不匹配,但我檢查了它,并且它在那里是正確的.
