‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍今天完成的事情：

1.完成了service层的编码，记录下过程：

（1）配置创建一个spring配置dao层对象的配置文件spring-service.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:context="http://www.springframework.org/schema/context"

xsi:schemaLocation="http://www.springframework.org/schema/beans

        http://www.springframework.org/schema/beans/spring-beans-4.3.xsd

        http://www.springframework.org/schema/context 

        http://www.springframework.org/schema/context/spring-context.xsd">

<!--扫描service包下所有使用注解的类型 -->

<context:component-scan base-package="com.wanghao.springmvc.service" />

</beans>

 ( 2 )创建EnrollService类

package com.wanghao.springmvc.service.impl;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Service;

import org.springframework.transaction.annotation.Transactional;

import com.wanghao.springmvc.dao.EnrollDao;

import com.wanghao.springmvc.models.Enroll;

import com.wanghao.springmvc.service.EnrollService;

@Service

public class EnrollServiceImpl implements EnrollService{

    @Autowired

    private EnrollDao dao;

    public EnrollDao getDao() {

        return dao;

    }

    public void setDao(EnrollDao dao) {

        this.dao = dao;

    }

    @Override@Transactional

    public int insert(Enroll enroll)throws Exception {

return dao.insert(enroll);

    }

    @Override@Transactional

    public int update(Enroll enroll)throws Exception {

return dao.update(enroll);

    }

    @Override@Transactional

    public int deleteByCondition(Enroll enroll)throws Exception {

return dao.deleteByCondition(enroll);

    }

    @Override@Transactional

    public int deleteByID(Enroll enroll)throws Exception {

return dao.deleteByID(enroll);

    }

    @Override@Transactional

    public List<Enroll> findByCondition(Enroll enroll)throws Exception {

return dao.findByCondition(enroll);

    }

    @Override@Transactional

    public Enroll findByID(Enroll enroll)throws Exception {

return dao.findByID(enroll);

    }

    @Override@Transactional

    public Long findCountByCondition(Enroll enroll)throws Exception {

return dao.findCountByCondition(enroll);

    }

}

3.单元测试

package com.wanghao.springmvc.service;

import static org.junit.Assert.*;

import javax.annotation.Resource;

import org.junit.Test;

import org.junit.runner.RunWith;

import org.springframework.test.context.ContextConfiguration;

import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.wanghao.springmvc.models.Enroll;

@RunWith(SpringJUnit4ClassRunner.class)

@ContextConfiguration({"classpath:spring/spring-dao.xml","classpath:spring/spring-service.xml"})

public class EnrollServiceTest {

    @Resource

    EnrollService enrollService;

    @Test

    public void testFindByID() throws Exception {

        Long id=new Long(1);

        Enroll enroll=new Enroll();

        enroll.setId(id);

        enroll=enrollService.findByID(enroll);

        System.out.println(enroll);

    }

}

2.完成controller层的编码，并把web.xml加入springmvc，顺利完成按id查询，其余几项由于时间原因没能完成，明天在完善

package com.wanghao.springmvc.controller;

import java.util.HashMap;

import java.util.Map;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.PathVariable;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.bind.annotation.ResponseBody;

import com.wanghao.springmvc.models.Enroll;

import com.wanghao.springmvc.service.EnrollService;

@Controller  

@RequestMapping("/enroll")  

public class EnrollController {       

    @Autowired  

    private EnrollService enrollService;  

    @RequestMapping(value = "findbyid/{id}",method = RequestMethod.GET)

    @ResponseBody

    public Map<String, Object> list(@PathVariable("id") Long id) throws Exception

    {       

Enroll enroll=new Enroll();

enroll.setId(id);

enroll=enrollService.findByID(enroll);

Map<String, Object> map = new HashMap<String, Object>();

map.put("enroll", enroll);

return map;

    }

}  

明天计划的事情：

1.完成增删查改的restful接口

2.学习PostMan进行接口

遇到的问题：

今天完成的内容较少，没看懂关于请求和响应对象的使用，明天继续研究

收获：‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

基本了解了springmvc实现restful的流程

初步了解了json的语法
