public com.baidu.core.core.ServiceResult com.baidu.controller.StudentController.updOneStudent(com.baidu.entity.Student)
to {POST /stu/updOne}: There is already 'studentController' bean method

重点是这句

com.baidu.controller.StudentController.updOneStudent(com.baidu.entity.Student)
to {POST /stu/updOne}: There is already 'studentController' bean method
翻译为:
com.baidu.controller.StudentController.updOneStudent (com.baidu.entity.Student)
到{POST /stu/updOne}:已经有'studentController' bean方法
