今天做的事：

做小课堂PPT；整合任务一代码，完成任务二。

使用springMVC整合任务一代码，并实现服务，实现RESTful风格接口

另外springMVC的配置文件也做了一些了解

项目结构

关键代码如下

springMVC-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:p="http://www.springframework.org/schema/p"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
      http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
      http://www.springframework.org/schema/context
      http://www.springframework.org/schema/context/spring-context-4.1.xsd
      http://www.springframework.org/schema/mvc
      http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">

    <!--开启注解-->
    <context:annotation-config></context:annotation-config>


    <!--自动扫描包-->
    <context:component-scan base-package="com.jnshu.controller"></context:component-scan>



    <!-- 3.配置jsp 显示ViewResolver ，根据前后缀获取view物理文件路径-->
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix">
            <value>/WEB-INF/pages/</value>
        </property>
        <property name="suffix">
            <value>.jsp</value>
        </property>
    </bean>

</beans>

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app metadata-complete="true" version="3.1"
         xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemalocation="http://xmlns.jcp.org/xml/ns/javaee
                    http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd">

  <!--过滤器，解决浏览器form表单只支持GET与POST请求，而DELETE、PUT等method并不支持的问题-->
  <filter>
    <filter-name>HiddenHttpMethodFilter</filter-name>
    <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
  </filter>

  <!--是配置springMVC的第一步。-->

  <servlet-mapping>
    <servlet-name>springMVC</servlet-name>
    <!-- 默认匹配所有的请求 -->
    <url-pattern>/</url-pattern>
  </servlet-mapping>


</web-app>

然后是service层代码

StudentService.java

package com.jnshu.service;


import com.jnshu.entitiy.Student;

import java.util.List;

/**
 * Created by Administrator on 2017/08/03.
 */
public interface StudentService {

    public List<Student> getAll();

    public void insert(Student student);

    public void delete(int id);

    public Student selectById(int id);

    public List<Student> selectByName(String name);

    public void update(Student student,Integer id);

}

StudentServiceImpl.java

package com.jnshu.service;

import com.jnshu.dao.StudentJDBCDAO;
import com.jnshu.entitiy.Student;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.Iterator;
import java.util.List;

/**
 * Created by Administrator on 2017/08/03.
 */
@Service
public class StudentServiceImpl implements StudentService{

    @Autowired
    private StudentJDBCDAO studentJDBCDAO;



    public List<Student> getAll(){

       List<Student> students = studentJDBCDAO.getAll();

       Iterator iterator = students.iterator();
       while(iterator.hasNext()){
           System.out.println(iterator.next());
       }
       return students;
    }

    public void insert(Student student){
        Integer integer = studentJDBCDAO.insertStudent(student);

        if(integer>0){
            System.out.println("插入成功");
        }

    }

    public void delete(int id){
        Integer integer = studentJDBCDAO.deleteStudent(id);

        if(integer>0){
            System.out.println("删除成功");
        }

    }

    public Student selectById(int id){
        Student student = studentJDBCDAO.selectStudent(id);

        System.out.println(student);

        return student;

    }

    public List<Student> selectByName(String name){
        List<Student> students = studentJDBCDAO.getStudentListByName(name);

        Iterator iterator = students.iterator();

        while(iterator.hasNext()){
            System.out.println(iterator.next());
        }

        return students;

    }

    public void update(Student student,Integer id){
        Integer integer = studentJDBCDAO.updateStudent(student,id);

        if(integer>0){
            System.out.println("更新成功");
        }

    }

}

最后的是控制层

RestController.java

package com.jnshu.controller;

import com.jnshu.entitiy.Student;
import com.jnshu.service.StudentService;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import java.util.List;
import java.util.Map;


/**
 * Created by Administrator on 2017/07/25.
 */
@Controller
public class RestController {

    private static Logger logger = Logger.getLogger(RestController.class);
    @Autowired
    private StudentService studentService;


    //获取列表
    @RequestMapping(value = "/stus",method = RequestMethod.GET)
    public String getAll(Model model){
        List<Student> students = studentService.getAll();

//        logger.info(studentService.getAll());
        model.addAttribute("students",students);
        return "list";
    }



    //插入信息
    //获取插入界面
    @RequestMapping(value = "/addStu",method = RequestMethod.GET)
    public String input(Map<String,Object> map){
        map.put("student",new Student());

        return "input";
    }
    //返回列表查看更新数据
    @RequestMapping(value = "/addStu",method = RequestMethod.POST)
    public String insert(Student student){
        studentService.insert(student);
        return "redirect:stus";
    }


    //由ID删除数据
    @RequestMapping(value = "/delStu/{id}",method = RequestMethod.DELETE)
    public String delete(@PathVariable("id") Integer id){
        studentService.delete(id);
        return "redirect:stus";

    }


    //由ID查找数据
    @RequestMapping(value = "/seeStu/{id}",method = RequestMethod.GET)
    public String selectById(@PathVariable("id") Integer id,Model model){
        Student student = studentService.selectById(id);
        model.addAttribute("student",student);
        return "detail";
    }


    //由姓名查找数据
    @RequestMapping(value = "/seeStu2/{name}",method = RequestMethod.GET)
    public String selectByName(@PathVariable("name") String name,Model model){
        List<Student> students = studentService.selectByName(name);
        model.addAttribute("students",students);

        return "list";
    }


    //获取更新列表
    @RequestMapping(value = "/updStu/{id}",method = RequestMethod.GET)
    public String in(@PathVariable("id") Integer id,Model model){
        Student student = studentService.selectById(id);

        model.addAttribute("student",student);
        return "in";

    }

    //更新数据
    @RequestMapping(value = "/updStu/{id}",method = RequestMethod.PUT)
    public String update(Student student,@PathVariable("id") Integer id){
        studentService.update(student,id);
        return "redirect:stus";
    }

}

用postman测过接口，控制台打印全部通过，postman测试页面通过一些，但还是有一点bug，应该是jetty启动服务时无法解决中文乱码的问题。明天再看一下

学习Iterator迭代器的用法；不过只是简单实用，用着感觉和加强版for循环用处差不多，只不过更加隐蔽了，不会让调用者直接接触到数据。

Iterator iterator = students.iterator();
while(iterator.hasNext()){
    System.out.println(iterator.next());
}

而加强版for要这么写

for(Student student:students){
    System.out.println(student);
}

明天计划：上传任务；整理一下任务二的知识点；更新一下博客；看一下任务三要求

问题：目前jetty启动服务还有测试时中文乱码问题未解决

收获：jsp页面的编写，一些el表达式，c标签啥的；Iterator迭代器；springMVC的配置文件又做了一些了解；对REST接口又多了一点认识。
