新建项目maven项目：microcloud-provider-dept-8001
在maven文件中新增springboot与mybatis整合相关依赖包
创建数据库脚本：DROP DATABASE IF EXISTS mldn_1 ;CREATE DATABASE mldn_1 CHARACTER SET UTF8 ;USE mldn_1 ;CREATE TABLE dept ( deptno BIGINT AUTO_INCREMENT , dname VARCHAR(50) , loc VARCHAR(50) , CONSTRAINT pk_deptno PRIMARY KEY(deptno)) ;INSERT INTO dept(dname,loc) VALUES ('开发部',database()) ;INSERT INTO dept(dname,loc) VALUES ('财务部',database()) ;INSERT INTO dept(dname,loc) VALUES ('市场部',database()) ;INSERT INTO dept(dname,loc) VALUES ('后勤部',database()) ;INSERT INTO dept(dname,loc) VALUES ('公关部',database()) ;
创建application.yml配置文件server: port: 8001mybatis: config-location: classpath:mybatis/mybatis.cfg.xml # mybatis配置文件所在路径 type-aliases-package: com.gwolf.vo # 定义所有操作类的别名所在包 mapper-locations: # 所有的mapper映射文件 - classpath:mybatis/mapper/**/*.xmlspring: datasource: type: com.alibaba.druid.pool.DruidDataSource # 配置当前要使用的数据源的操作类型 driver-class-name: com.mysql.cj.jdbc.Driver # 配置MySQL的驱动程序类 url: jdbc:mysql://localhost:3306/mldn_1?serverTimezone=UTC # 数据库连接地址 username: root # 数据库用户名 password: root # 数据库连接密码 dbcp2: # 进行数据库连接池的配置 min-idle: 5 # 数据库连接池的最小维持连接数 initial-size: 5 # 初始化提供的连接数 max-total: 5 # 最大的连接数 max-wait-millis: 200 # 等待连接获取的最大超时时间 application: name: microcloud-provider-deptsecurity: user: name: gwolf #用户名 password: gwolf #密码 role: #授权角色 - USER
创建VO对象：package com.gwolf.vo;public class Dept implements java.io.Serializable { private Long deptno; private String dname; private String loc; public Long getDeptno() { return deptno; } public void setDeptno(Long deptno) { this.deptno = deptno; } @Override public String toString() { return 'Dept{' + 'deptno=' + deptno + ', dname='' + dname + '\'' + ', loc='' + loc + '\'' + '}'; } public String getDname() { return dname; } public void setDname(String dname) { this.dname = dname; } public String getLoc() { return loc; } public void setLoc(String loc) { this.loc = loc; }}
创建mybatis配置文件：
创建dept.xml文件
创建service类DeptServiceImplpackage com.gwolf.microcloud.service.impl;import com.gwolf.microcloud.dao.IDeptDAO;import com.gwolf.microcloud.service.IDeptService;import com.gwolf.vo.Dept;import org.springframework.stereotype.Service;import javax.annotation.Resource;import java.util.List;@Servicepublic class DeptServiceImpl implements IDeptService{ @Resource private IDeptDAO deptDAO; @Override public Dept get(long id) { return this.deptDAO.findById(id); } @Override public boolean add(Dept dept) { return this.deptDAO.doCreate(dept); } @Override public List
创建项目启动类，注意项目启动类必须在所有类的父目录上面package com.gwolf.microcloud;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplicationpublic class Dept_8001_StartSpringCloudApplication { public static void main(String[] args) { SpringApplication.run(Dept_8001_StartSpringCloudApplication.class,args); }}
编写项目测试类：package com.gwolf.microcloud.service;import com.gwolf.microcloud.Dept_8001_StartSpringCloudApplication;import com.gwolf.vo.Dept;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.boot.test.context.SpringBootTest;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import org.springframework.test.context.web.WebAppConfiguration;import javax.annotation.Resource;@SpringBootTest(classes = Dept_8001_StartSpringCloudApplication.class)@RunWith(SpringJUnit4ClassRunner.class)@WebAppConfigurationpublic class IDeptServiceTest { @Resource private IDeptService deptService; @Test public void testGet() { System.out.println(this.deptService.get(1)); } @Test public void testAdd() { Dept dept = new Dept(); dept.setDname('测试部-' + System.currentTimeMillis()); System.out.println(this.deptService.add(dept)); } @Test public void testList() { System.out.println(this.deptService.list()); }}
整合完毕，执行测试类的list方法，查看结果：[Dept{deptno=1, dname='测试部46', loc='mldn_1'}, Dept{deptno=2, dname='测试部12', loc='mldn_1'}, Dept{deptno=3, dname='测试部83', loc='mldn_1'}, Dept{deptno=4, dname='web测试', loc='mldn_1'}, Dept{deptno=5, dname='web测试', loc='mldn_1'}, Dept{deptno=6, dname='web测试', loc='mldn_1'}, Dept{deptno=7, dname='测试部89', loc='mldn_1'}, Dept{deptno=8, dname='测试部90', loc='mldn_1'}, Dept{deptno=9, dname='测试部24', loc='mldn_1'}, Dept{deptno=10, dname='测试部19', loc='mldn_1'}, Dept{deptno=11, dname='测试部55', loc='mldn_1'}, Dept{deptno=12, dname='测试部-78', loc='mldn_1'}, Dept{deptno=13, dname='web测试', loc='mldn_1'}, Dept{deptno=14, dname='web测试365', loc='mldn_1'}]，成功打印，整合成功。
