SpringBoot 项目整合源码
SpringBoot 项目整合
一、项目准备
1.1 快速创建 SpringBoot 项目
博客地址：快速搭建 SpringBoot 项目（看完 【 1. 快速创建 SpringBoot 项目】 就可以回到这里了）
1.2 项目结构图如下
1.3 数据表结构图如下
CREATE TABLE `employee` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`username` varchar(255) DEFAULT NULL,
`name` varchar(255) DEFAULT NULL,
`password` varchar(255) DEFAULT NULL,
`email` varchar(255) DEFAULT NULL,
`age` int(11) DEFAULT NULL,
`admin` bit(1) DEFAULT b'0',
`dept_id` bigint(20) DEFAULT NULL,
PRIMARY KEY (`id`) USING BTREE
) ENGINE=InnoDB AUTO_INCREMENT=10 DEFAULT CHARSET=utf8 ROW_FORMAT=DYNAMIC;
1.4 运行结果
二、项目实现
1. pom.xml 配置文件
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

2. application.properties 配置文件
# 修改端口号
server.port=80
# mysql 4要素
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql:///springboot?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8
spring.datasource.username=root
spring.datasource.password=admin
#设置SQL打印日志
logging.level.com.yy.mapper=trace
#一般我们会做3个配置,其余默认即可
#暴露session对象的属性
spring.freemarker.expose-session-attributes=true
#配置为传统模式，空值自动处理
spring.freemarker.settings.classic_compatible=true
#重新指定模板文件后缀 springboot 2.2.x 后 默认后缀为 .ftlh
spring.freemarker.suffix=.ftl
3. APP 启动类
package com.yy;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
// mybatis 接口扫描注解
@MapperScan("com.yy.mapper")
public class App {
public static void main(String[] args) {
SpringApplication.run(App.class, args);
}
}
4. EmployeeController 控制器
package com.yy.controller;
import com.github.pagehelper.PageInfo;
import com.yy.domain.Employee;
import com.yy.qo.EmployeeQueryObject;
import com.yy.service.IEmployeeService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
@RequestMapping("/employee")
public class EmployeeController {
@Autowired
private IEmployeeService employeeService;
@RequestMapping("/list")
public String list(Model model, @ModelAttribute("qo")EmployeeQueryObject qo) {
// mybatis 的分页插件，qo 是页面传过来的模糊条件查询参数以及当前页和每页条数
PageInfo<Employee> pageInfo = employeeService.query(qo);
model.addAttribute("pageInfo", pageInfo);
return "employee/list";
}
}
5. IEmployeeService 接口
package com.yy.service;
import com.github.pagehelper.PageInfo;
import com.yy.domain.Employee;
import com.yy.qo.EmployeeQueryObject;
import java.util.List;
public interface IEmployeeService {
int delete(Long id);
int add(Employee record);
Employee selectById(Long id);
List<Employee> selectAll();
int update(Employee record);
PageInfo<Employee> query(EmployeeQueryObject qo);
}
6. EmployeeServiceImpl 接口
package com.yy.service.impl;
import com.github.pagehelper.PageHelper;
import com.github.pagehelper.PageInfo;
import com.yy.domain.Employee;
import com.yy.mapper.EmployeeMapper;
import com.yy.qo.EmployeeQueryObject;
import com.yy.service.IEmployeeService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import java.util.List;
@Service
@Transactional
public class EmployeeServiceImpl implements IEmployeeService {
@Autowired(required = false)
private EmployeeMapper employeeMapper;
@Override
public int delete(Long id) {
return 0;
}
@Override
public int add(Employee record) {
return 0;
}
@Override
public Employee selectById(Long id) {
return null;
}
@Override
public List<Employee> selectAll() {
return null;
}
@Override
public int update(Employee record) {
return 0;
}
@Override
public PageInfo<Employee> query(EmployeeQueryObject qo) {
// 使用 mybatis 分页插件，传入当前页和每页条数
PageHelper.startPage(qo.getCurrentPage(), qo.getPageSize());
List<Employee> list = employeeMapper.selectForList(qo);
return new PageInfo<>(list);
}
}
7. EmployeeMapper 接口
package com.yy.mapper;
import com.yy.domain.Employee;
import com.yy.qo.EmployeeQueryObject;
import java.util.List;
public interface EmployeeMapper {
int deleteByPrimaryKey(Long id);
int insert(Employee record);
Employee selectByPrimaryKey(Long id);
List<Employee> selectAll();
int updateByPrimaryKey(Employee record);
List<Employee> selectForList(EmployeeQueryObject qo);
}
8. EmployeeMapper 接口
<?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.yy.mapper.EmployeeMapper" >
<resultMap id="BaseResultMap" type="com.yy.domain.Employee" >
<id column="id" property="id" />
<result column="username" property="username" />
<result column="name" property="name" />
<result column="password" property="password" />
<result column="email" property="email" />
<result column="age" property="age" />
<result column="admin" property="admin" />
<result column="dept_id" property="deptId" />
</resultMap>
<delete id="deleteByPrimaryKey" >
delete from employee
where id = #{id}
</delete>
<insert id="insert" useGeneratedKeys="true" keyProperty="id" >
insert into employee (username, name, password, email, age, admin, dept_id)
values (#{username}, #{name}, #{password}, #{email}, #{age}, #{admin}, #{deptId})
</insert>
<update id="updateByPrimaryKey" >
update employee
set username = #{username},
name = #{name},
password = #{password},
