基于javaweb+mysql的ssm鲜花商城系统(java+ssm+jsp+jquery+mysql)

这是一个基于JavaWeb技术栈的鲜花商城系统，使用了SSM（Spring MVC + Spring + MyBatis）框架进行开发。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/flower_shop"/>
        <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 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>
 
    <!-- 开启注解事务 -->
    <tx:annotation-driven transaction-manager="transactionManager"/>
 
</beans>

核心代码片段：控制器类FlowerController.java

package com.example.controller;
 
import com.example.entity.Flower;
import com.example.service.FlowerService;
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.RequestParam;
 
@Controller
@RequestMapping("/flower")
public class FlowerController {
 
    @Autowired
    private FlowerService flowerService;
 
    @RequestMapping("/list")
    public String list(Model model) {
        model.addAttribute("flowers", flowerService.getAllFlowers());
        return "flowerList";
    }
 
    @RequestMapping("/add")
    public String add(@RequestParam String name, @RequestParam double price, Model model) {
        Flower
