基于javaweb+mysql的ssm+maven民宿管理系统(java+ssm+jsp+bootstrap+jquery+mysql)

这是一个基于JavaWeb、SSM（Spring MVC + Spring + MyBatis）框架和Maven构建工具的民宿管理系统。以下是部分核心代码和配置文件的示例：

Maven依赖（pom.xml）

<dependencies>
    <!-- Spring MVC -->
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-webmvc</artifactId>
        <version>5.2.10.RELEASE</version>
    </dependency>
    <!-- MyBatis -->
    <dependency>
        <groupId>org.mybatis</groupId>
        <artifactId>mybatis-spring</artifactId>
        <version>2.0.6</version>
    </dependency>
    <!-- MySQL -->
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>8.0.23</version>
    </dependency>
    <!-- 其他依赖... -->
</dependencies>

Spring配置文件（spring-config.xml）

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
                           http://www.springframework.org/schema/beans/spring-beans.xsd">
 
    <!-- 数据源配置 -->
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
        <property name="driverClassName" value="com.mysql.cj.jdbc.Driver"/>
        <property name="url" value="jdbc:mysql://localhost:3306/your_database"/>
        <property name="username" value="your_username"/>
        <property name="password" value="your_password"/>
    </bean>
 
    <!-- SqlSessionFactoryBean -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
    </bean>
 
    <!-- 扫描Mapper接口 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.yourpackage.mapper"/>
    </bean>
 
    <!-- 其他Bean配置... -->
</beans>

MyBatis配置文件（mybatis-config.xml）

<configuration>
    <mappers>
        <mapper resource="com/yourpackage/mapper/YourMapper.xml"/>
        <!-- 其他Mapper配置 -->
    </mappers>
</configuration>

Controller层代码示例（HotelController.java）

@Controller
@RequestMapping("/hotel")
public class HotelController {
 
    @Autowired
    private IHotelService hotelService;
 
    @RequestMapping("/list")
    public ModelAndView list() {
        Lis
