org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.lang.Object[]] to type [com.jzh.graduation.entity.SysPermission] for value '{1, 权限管理, /sys/permission/**}'; nested exception is org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type [java.lang.Integer] to type [com.jzh.graduation.entity.SysPermission]
原因：返回结果应该转换为对象SysPermission，JPA原生sql写在SysUserDao下（返回结果转换为SysUser），返回结果无法转换，应该写在SysPermissionDao下。
