一。今天改SSM，增加可以，删除可以，编辑可以跳转，写完之后提交不可以。还是rest的问题

public class StudentController {
    @Autowired
    StudentService studentService;

    @RequestMapping(value = "/listStudent",method = RequestMethod.GET)
    public ModelAndView listStudent(Page page){

        ModelAndView mav = new ModelAndView();
        List<Student> ss= studentService.list(page);
        int total = studentService.total();

        page.caculateLast(total);

        // 放入转发参数
        mav.addObject("ss", ss);
        // 放入jsp路径
        mav.setViewName("listStudent");
        return mav;
    }

    @RequestMapping(value = "/addStudent",method = RequestMethod.POST)
    public ModelAndView addStudent(Student student){
        studentService.add(student);
        ModelAndView mav = new ModelAndView("redirect:/listStudent");
        return mav;
    }
    @RequestMapping(value = "/deleteStudent/{id}",method = RequestMethod.DELETE)
    public ModelAndView deleteStudent(Student student){
        studentService.delete(student);
        ModelAndView mav = new ModelAndView("redirect:/listStudent");
        return mav;
    }
    @RequestMapping(value = "editStudent/{id}",method = RequestMethod.POST)
    public ModelAndView editStudent(Student student){
        Student s= studentService.get(student.getId());
        ModelAndView mav = new ModelAndView("editStudent");
        mav.addObject("s", s);
        return mav;
    }
    @RequestMapping(value = "updateStudent/{id}",method = RequestMethod.PUT)
    public ModelAndView updateStudent(Student student){
        studentService.update(student);
        ModelAndView mav = new ModelAndView("redirect:/listStudent");
        return mav;
    }

二。根据教程做了一个图书馆的SSM，双表联查。看看效果怎么样

架构如下：

@Controller
@RequestMapping("/book") // url:/模块/资源/{id}/细分 /seckill/list
public class BookController {
    private Logger logger = (Logger) LoggerFactory.getLogger(this.getClass());

    @Autowired
    private BookService bookService;

    @RequestMapping(value = "/list", method = RequestMethod.GET)
    private String list(Model model) {
        List<Book> list = bookService.getList();
        model.addAttribute("list", list);
        // list.jsp + model = ModelAndView
        return "list";// WEB-INF/jsp/"list".jsp
    }

    @RequestMapping(value = "/{bookId}/detail", method = RequestMethod.GET)
    private String detail(@PathVariable("bookId") Long bookId, Model model) {
        if (bookId == null) {
            return "redirect:/book/list";
        }
        Book book = bookService.getById(bookId);
        if (book == null) {
            return "forward:/book/list";
        }
        model.addAttribute("book", book);
        return "detail";
    }

    //ajax json
    @RequestMapping(value = "/{bookId}/appoint", method = RequestMethod.POST, produces = {
            "application/json; charset=utf-8" })
    @ResponseBody
    private Result<AppointExecution> appoint(@PathVariable("bookId") Long bookId, @RequestParam("studentId") Long studentId) {
        if (studentId == null || studentId.equals("")) {
            return new Result<>(false, "学号不能为空");
        }
        //AppointExecution execution = bookService.appoint(bookId, studentId);//错误写法，不能统一返回，要处理异常（失败）情况
        AppointExecution execution = null;
        try {
            execution = bookService.appoint(bookId, studentId);
        } catch (NoNumberException e1) {
            execution = new AppointExecution(bookId, AppointStateEnum.NO_NUMBER);
        } catch (RepeatAppointException e2) {
            execution = new AppointExecution(bookId, AppointStateEnum.REPEAT_APPOINT);
        } catch (Exception e) {
            execution = new AppointExecution(bookId, AppointStateEnum.INNER_ERROR);
        }
        return new Result<AppointExecution>(true, execution);
    }

别的都没问题，唯有控制器报错：

Error:(30, 14) java: 找不到符号

  符号:   方法 addAttribute(java.lang.String,java.util.List<com.how2java.lyf.entity.Book>)

  位置: 类型为javax.enterprise.inject.Model的变量 model

Error:(44, 14) java: 找不到符号

  符号:   方法 addAttribute(java.lang.String,com.how2java.lyf.entity.Book)

  位置: 类型为javax.enterprise.inject.Model的变量 model

搞不定，明天再搞。

三。准备小课堂的APP，小课堂的题目是：什么是RESTFUL？REST的请求方法有哪些，有什么区别？

明天的计划：准备小课堂

遇到的问题：项目还是无法运行

今天的收获：做了个图书馆的项目，后天做好；

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，
