人力资源管理系统（大二数据库课设） spring boot，Mybatis+bootstap，ajax项目

由于您的问题涉及到一个完整的项目，我将提供一个简化的解决方案，包括Spring Boot项目的基本结构和配置，以及一个简单的MyBatis Mapper接口示例。

1. 创建Spring Boot项目：

// pom.xml 依赖
<dependencies>
    <!-- Spring Boot Web Starter -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
 
    <!-- MyBatis Framework -->
    <dependency>
        <groupId>org.mybatis.spring.boot</groupId>
        <artifactId>mybatis-spring-boot-starter</artifactId>
        <version>2.1.3</version>
    </dependency>
 
    <!-- Database Driver -->
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>8.0.19</version>
    </dependency>
</dependencies>

2. 配置application.properties:

spring.datasource.url=jdbc:mysql://localhost:3306/hrm?useSSL=false&serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=yourpassword
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
 
mybatis.mapper-locations=classpath:mapper/*.xml
mybatis.type-aliases-package=com.yourpackage.model

3. 创建一个简单的MyBatis Mapper接口:

// UserMapper.java
package com.yourpackage.mapper;
 
import com.yourpackage.model.User;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;
 
@Repository
public interface UserMapper {
    @Select("SELECT * FROM users WHERE id = #{id}")
    User getUserById(int id);
}

4. 创建一个Service层来使用Mapper:

// UserService.java
package com.yourpackage.service;
 
import com.yourpackage.mapper.UserMapper;
import com.yourpackage.model.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
 
@Service
public class UserService {
    @Autowired
    private UserMapper userMapper;
 
    public User getUserById(int id) {
        return userMapper.getUserById(id);
    }
}

5. 创建一个Con
