记录一下从零开始搭建一个springboot+springcloud+mybatis本地项目的demo的过程。纯代码小白一枚，若有不足或错误之处，欢迎广大朋友指出！

开发环境准备：  
IDE：IntelliJ Idea 2019.3  
数据库：mysql 8.0.2.2  
SpringBoot版本：2.2.0.RELEASE  
SpringCloud版本：Hoxton.RELEASE

一、创建一个新的Idea项目

打开Idea，单击New->File->Project，选择Maven，直接下一步  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xhb3poYW5nNDI_size_16_color_FFFFFF_t_70]  
输入我们的项目名，我这里起名为pam，单击Finish完成创建

二、右键单击project下的父节点->New->Module，创建一个注册中心服务端的Module，输入一下名称，我这里以pam-server为例，直接选finish；  
同理再创建一个客户端的Module，输入一下名称，我这里以pam-service为例，直接选finish，结构如图所示：

三、单击File->Settings->Maven，配置一下本地的maven，单击OK  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xhb3poYW5nNDI_size_16_color_FFFFFF_t_70 3]

四、在最外层pom文件引入一下springboot、springcloud及mybatis的依赖。这里引入的springboot版本为2.2.0-RELEASE，与之相对应的springcloud版本为Hoxton.RELEASE。注意二者版本需要相适配，否则会启动报错。这里额外引入了几个常用依赖，直接在maven单击一下刷新，仓库即可在线将所需依赖下载进去。

        </dependencies>

五、创建如图所示的目录结构：  
①编写注册中心，注册中心目录结构：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xhb3poYW5nNDI_size_16_color_FFFFFF_t_70 4]  
编写WebApplication启动类，添加注解@EnableEurekaServer和@SpringBootApplication，我这里想做一个纯注册中心，不与数据库挂钩，所以增加了一个exclude = DataSourceAutoConfiguration.class，启动项目时不自动与数据库连接，若想让注册中心也连接数据库，这个exclude也可以不要。如图所示：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xhb3poYW5nNDI_size_16_color_FFFFFF_t_70 5]  
编写application.yml

server:
      port: 8081
    eureka:
      instance:
        hostname: 127.0.0.1
      server:
        enable-self-preservation: false # 关闭自我保护模式（默认为打开）
        eviction-interval-timer-in-ms: 600000 # 续期时间，即扫描失效服务的间隔时间 一分钟，本地测试不需这么频繁，调为1小时
      client:
        register-with-eureka: false #自己就是注册中心，不用注册自己
        fetch-registry: false #是否去注册中心获取其他服务的地址
        serviceUrl:
          defaultZone: http://${ eureka.instance.hostname}:${ server.port}/eureka/
    spring:
      application:
        name: xinrong
      freemarker:
        prefer-file-system-access: false

编写bootstrap.yml：

spring:
      cloud:
        config:
          enabled: false

编写log4j.properties：

log4j.rootLogger=info, stdout
    
    log4j.appender.stdout=org.apache.log4j.ConsoleAppender
    log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
    log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m%n
    
    log4j.appender.logfile=org.apache.log4j.FileAppender
    log4j.appender.logfile.File=target/spring.log
    log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
    log4j.appender.logfile.layout.ConversionPattern=%d %p [%c] - %m%n

②编写消费者pam-service，消费者目录结构：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xhb3poYW5nNDI_size_16_color_FFFFFF_t_70 6]  
编写消费者启动类PamApplication.java，添加注解@MapperScan(basePackages = \{“com.xinrong.pam.\*.mapper”\})  
含义：mybatis中Mapper文件对应的包，启动项目时会自动扫描  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xhb3poYW5nNDI_size_16_color_FFFFFF_t_70 7]  
编写消费者application.yml：

server:
      port: 8088 #端口号8088
    eureka:
      instance:
        hostname: 127.0.0.1
      server:
        enable-self-preservation: false # 关闭自我保护模式（默认为打开）
        eviction-interval-timer-in-ms: 600000 # 续期时间，即扫描失效服务的间隔时间 一分钟
      client:
        register-with-eureka: true #注册到注册中心
        fetch-registry: true #是否去注册中心获取其他服务的地址：是
        serviceUrl:
          defaultZone: http://127.0.0.1:8081/eureka/ #注册中心地址
    mybatis:
      mapper-locations: mapper/*  #mybatis映射文件路径
      config-location: classpath:/mybatis/mybatis-config.xml #mybatis配置文件路径
    spring:
      application:
        name: pam #项目名
      datasource:
        url: jdbc:mysql://127.0.0.1:3306/pam?characterEncoding=utf-8&serverTimezone=Asia/Shanghai
        username: root
        password: root
        driver-class-name: com.mysql.cj.jdbc.Driver
      freemarker:
        prefer-file-system-access: false
    jdbc:
      driverClass: com.mysql.jdbc.Driver
      url: jdbc:mysql://localhost:3306/pam
      username: root
      password: root

在数据库中创建一个pam\_user表：

create table pam_user(
    	objectId varchar(50) not null primary key ,
    	userName varchar(50),
    	password varchar(255),
    	phoneNo varchar(20),
    	sex varchar(5),
    	birthDay date,
    	Email varchar(50)
    );

插入一条测试数据：  
![在这里插入图片描述][20210113010627176.png]

编写user文件夹，创建五层架构，在domain中创建一个实体类User：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xhb3poYW5nNDI_size_16_color_FFFFFF_t_70 8]  
创建controller类接口及实现类，添加@RestController注解，在接口上添加@RequestMapping注解：  
接口：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xhb3poYW5nNDI_size_16_color_FFFFFF_t_70 9]  
实现类：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xhb3poYW5nNDI_size_16_color_FFFFFF_t_70 10]  
同理，添加service接口及实现类，注意在实现类上添加@Service注解：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xhb3poYW5nNDI_size_16_color_FFFFFF_t_70 11]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xhb3poYW5nNDI_size_16_color_FFFFFF_t_70 12]  
创建mapper文件，编写Mapper接口，添加@Repository注解：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xhb3poYW5nNDI_size_16_color_FFFFFF_t_70 13]

在resources中创建mybatis文件夹，编写mybatis-config.xml配置文件：  
![在这里插入图片描述][20210113010000927.png]

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">
    <configuration>
        <settings>
            
            <setting name="mapUnderscoreToCamelCase" value="true"/>
            
            <setting name="logImpl" value="STDOUT_LOGGING" />
        </settings>
    </configuration>

编写mapper文件，创建一个User类的mybatis映射文件：  
![在这里插入图片描述][20210113010101783.png]

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
    
    <mapper namespace="com.xinrong.pam.user.mapper.UserMapper">
        <select id="getAll" resultType="com.xinrong.pam.user.domain.User">
            select * from pam_user
        </select>
    </mapper>

至此，Demo代码编写完毕，首先启动注册中心pam\_server，启动成功，通过地址http://127.0.0.1:8081/，成功查看到了注册中心管理界面：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xhb3poYW5nNDI_size_16_color_FFFFFF_t_70 14]

启动服务pam\_service：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xhb3poYW5nNDI_size_16_color_FFFFFF_t_70 15]  
启动成功，再次查看注册中心管理界面，可以看到pam服务成功注册到了注册中心：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xhb3poYW5nNDI_size_16_color_FFFFFF_t_70 16]  
通过浏览器地址栏键入“http://127.0.0.1:8088/controller/pam/user/getAll”，成功查询到了库中录入的测试数据。至此，springBoot的项目基本架构搭建成功！
