这是一个基于JavaWeb技术栈的SSM（Spring MVC + Spring + MyBatis）框架的茶叶商城管理系统。由于代码量较大，我将提供一些核心代码片段和配置文件的示例。
核心配置文件applicationContext.xml：
<?xml version="1.0" encoding="UTF-8"?>
<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">
<!-- 数据库连接池 -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver"/>
<property name="url" value="jdbc:mysql://localhost:3306/tea_store"/>
<property name="username" value="root"/>
<property name="password" value="password"/>
</bean>
<!-- 配置SqlSessionFactory -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="configLocation" value="classpath:mybatis-config.xml"/>
</bean>
<!-- 配置Mapper扫描器 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.example.mapper"/>
</bean>
<!-- 事务管理器配置, 使用DataSourceTransactionManager -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean>
<!-- 开启注解事务管理 -->
<tx:annotation-driven transaction-manager="transactionManager"/>
</beans>核心控制器类TeaController.java：
package com.example.controller;
import com.example.model.Tea;
import com.example.service.TeaService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
@RequestMapping("/tea")
public class TeaController {
@Autowired
private TeaService teaService;
@RequestMapping(value = "/list", method = RequestMethod.GET)
public String listTeas(Model model) {
model.addAttribute("teas", teaService.findAll());
return "tea_list";
}
// 其他CRUD操作的映射
}服务层接口TeaService.java：
package com.example.service;
import com.example.mod
