# 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）][SpringBoot _ _ _1. _ SpringBoot _]

### 1.2 项目结构图如下 ###

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3p6dmFy_size_16_color_FFFFFF_t_70]

### 1.3 数据表结构图如下 ###

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3p6dmFy_size_16_color_FFFFFF_t_70 1]

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 ###

### 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 ###
