一。今天主要是准备restful小课堂，但是代码关于小课堂的地方老是运行不对，所以就把小课堂延期到明天，扣了十分。写了一下PPT
二。SSM框架加上restful可以正常运行了，控制器是手打的，如下：
@Controller
public class StudentController{
private static final Logger log = LoggerFactory.getLogger(StudentController.class);
@Resource
private StudentService studentService;
@RequestMapping(Value = "/student/list", method = RequestMethod.GET)
public String getAll(Model model) {
log.info("/student/list GET");
List<Student> studentList = studentService.getAll();
model.addAttribute("studentList",studentList);
log.info("get student size is {}",studentList.size());
return "list";
}
@RequestMapping(value = "/student/{id}",method = Requestmethod.DELETE)
public String delStudent(@PathVariable Long id) {
log.info("/student/{id} DELETE id is {}",id);
studentService.deleteByPrimaryKey(id);
log.info("delete {} success",id);
return "redirect:/student/list";
}
@RequestMapping(value = "/student/a",method = RequestMethod.GET)
public String toAddStudent() {
log.info("open/student/a GET");
return "add";
}
@RequestMapping(value = "/student",method = RequestMethod.POST)
public String addStudent(Student student) {
studentService.insert(student);
log.info("insert student information is {}", student);
return "redirect:/student/list";
}
@RequestMapping(value = "/student/u/{id}", method = RequestMethod.GET)
public String toUpdateStudent(@PathVariable Long id, Model model){
Student student = studentService.selectByPrimaryKey(id);
model.addAttribute("student",student);
return "update";
}
@RequestMapping(value = "/student/{id}",method = RequestMethod.PUT)
public String UpdateStudent(@PathVariable Long id) {
System.out.println(id)
log.info("/student/{id} the request parameters are id:{});
System.out.println(comeFrom);
student.setId(id);
student.setCreateAt(createAt);
int success = studentService.updateBByPrimaryKey(student);
log.info("update student success is {}",success);
return "redirect:/student/list";
}
@RequestMapping(value = "/student/list/json", method = RequestMethod.GET)
public String getAllByJson(Model model) {
List<Student> studentList = studentService.getAll();
model.addAttribute("studentList", studentList);
return "jsonList";
}

<br>创建时间<input type="text" name="createAt" value="${student.createAt}" style="text-align: center">
<input type="submit" value="修改">
</form>
</body>
</html>
正常运行如图：
明天的计划：1.看看孟阳师兄的小课堂是怎么讲的2.把我的小课堂SSM代码弄好3.讲小课堂
遇到的问题：restful不太理解，以至于小课堂要延期了
今天的收获：SSM框架的restful可以运行的了
java任务二开始时间：2018.01.25
预计demo时间：2018.02.12
可能有延期风险，原因是：基础比较差，
