Invalid property 'jt' of bean class [cn.xiaozhang.a_jdbctemplate.UserDaoImpl

在学spring框架时遇到了一个错误
Invalid property ‘jt’ of bean class [cn.xiaozhang.a_jdbctemplate.UserDaoImpl]: Bean property ‘jt’ is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?
解决方法：
在UserDaoImpl中添加jt 的get和set方法
