服务端：基础框架搭建

（一）搭建框架

我这里用的开发工具时idea，服务端用的框架时Spring+SpringMVC+mybatis框架，之前一直是在用这个框架但还没有自己真正搭建过这个框架，所有说这里就从最基本的搭建框架开始，我这里也是按照一个前辈的来搭建的。废话不多说了直接干吧。
1.打开idea，创建maven项目，File-New-Project

这里写图片描述

2.选择Maven，勾选Create from archetype,选择org.apache.cocoon:cocoon-22-archetype-webapp,然后点击Next

这里写图片描述
3.填写Groupid和Artifactid点击Next

这里写图片描述
4.选择自己本地安装的maven

这里写图片描述

5.填写项目名创建项目完成

这里写图片描述
6.打开pom.xml加入坏境所需的依赖

7.添加Java目录

    <!--配置spring mvc-->

    <mvc:annotation-driven/>

    <!--2.静态资源默认servlet配置-->

jdbc.properties

driver=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8

password=admin

mybatis-config.xml

        "http://mybatis.org/dtd/mybatis-3-config.dtd">

        <!--开启驼峰命名转换Table:create_time到 Entity(createTime)-->
        <setting name="mapUnderscoreToCamelCase" value="true"/>
    </settings>
</configuration>

9.增加必要主要类

这里写图片描述

UserMapper

package com.cjq.dao;

import com.cjq.model.User;

import java.util.List;

/**
 * Created by struggle on 2017/7/26.
 */
public interface UserMapper {

    List<User> getAll();

    void save(User user);

    void delete(int id);

    void update(User user);

    User getUserById(int id);

}

UserMapper.xml

<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.cjq.dao.UserMapper">
    <!--目的:为dao接口方法提供sql语句配置
    即针对dao接口中的方法编写我们的sql语句-->

    <select id="getAll" resultType="com.cjq.model.User">
        select * from user
    </select>
    <select id="getUserById" resultType="com.cjq.model.User" parameterType="int">
        select * from user where id=#{id}
    </select>
    <insert id="save" parameterType="com.cjq.model.User">
        insert into user(id,name,age,password) values(#{id},#{name},#{age},#{password})
    </insert>
    <delete id="delete" parameterType="int">
        delete from user where id=#{id}
    </delete>
    <update id="update" parameterType="com.cjq.model.User">
        update user set name=#{name},age=#{age},password=#{password} where id=#{id}
    </update>
</mapper>

UserService

package com.cjq.service;

import com.cjq.model.User;
import org.springframework.transaction.annotation.Transactional;

import java.util.List;

/**
 * Created by struggle on 2017/7/26.
 */
@Transactional
public interface UserService {

    List<User> getAll();

    void save(User user);

    void delete(int id);

    void update(User user);

    User getUserById(int id);
}

UserServiceImpl

package com.cjq.service.impl;

import com.cjq.dao.UserMapper;
import com.cjq.model.User;
import com.cjq.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

/**
 * Created by struggle on 2017/7/26.
 */
@Service("userService")
public class UserServiceImpl implements UserService {

    @Autowired
    UserMapper userMapper;
    public List<User> getAll() {
        return userMapper.getAll();
    }

    public void save(User user) {
       userMapper.save(user);
    }

    public void delete(int id) {
      userMapper.delete(id);
    }

    public void update(User user) {
     userMapper.update(user);
    }

    public User getUserById(int id) {
        return userMapper.getUserById(id);
    }
}

10.使用Spring-test 测试
UserServiceImplTest

package com.cjq.servoce.impl;

import com.cjq.model.User;
import com.cjq.service.UserService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import javax.annotation.Resource;
import java.util.Date;
import java.util.List;

/**
 * Created by struggle on 2017/7/26.
 */

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:spring/spring-*.xml")
public class UserServiceImplTest {
    @Resource
    Date date;
    @Resource
    UserService userService;

    @Test
    public void testDate(){
        System.out.println(date);
    }
    @Test
    public void testGetAll(){
        List<User> list=userService.getAll();
        for(User user:list){
            System.out.println(user.getName());
        }
    }
    @Test
    public void testGetUserById(){
        System.out.println(userService.getUserById(1).getName());
    }
    @Test
    public void testSave(){
        User user=new User();
        user.setName("test");
        user.setAge(11);
        user.setPassword("pass");
        userService.save(user);
    }
    @Test
    public void testDelete(){
        userService.delete(1);
    }
    @Test
    public void testUpdate(){
        User user=userService.getUserById(2);
        user.setName("hello");
        userService.update(user);
    }
}

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4"
         xmlns="http://java.sun.com/xml/ns/j2ee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

  <!--用maven创建的web-app需要修改servlet的版本为3.1-->
  <!--配置DispatcherServlet-->
  <servlet>
    <servlet-name>cjq-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!--
        配置SpringMVC 需要配置的文件
        spring-dao.xml，spring-service.xml,spring-web.xml
        Mybites -> spring -> springMvc
    -->
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring/spring-*.xml</param-value>
    </init-param>
  </servlet>

  <servlet-mapping>
    <servlet-name>cjq-dispatcher</servlet-name>
    <!--默认匹配所有请求-->
    <url-pattern>/</url-pattern>
  </servlet-mapping>


  <welcome-file-list>
    <welcome-file>/login.jsp</welcome-file>
  </welcome-file-list>
</web-app>

好了基本上就是这样的了，我这个也是按照前辈的来的，转载出自
这里,其实这个搭建起来还是挺容易的，按照这个来的我这里一点问题都没有，好了基本的服务端的框架算是搭建起来了
