基于SSM框架流浪动物救助及领养管理系统(spring+springmvc+mybatis+jsp+jquery+layui)

这是一个基于SSM（Spring + Spring MVC + MyBatis）框架的流浪动物救助和领养管理系统的简化版本。以下是系统的核心部分代码示例：

applicationContext.xml（Spring配置）

<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.jdbc.Driver"/>
        <property name="url" value="jdbc:mysql://localhost:3306/db_pet"/>
        <property name="username" value="root"/>
        <property name="password" value="password"/>
    </bean>
 
    <!-- MyBatis的SqlSessionFactory -->
    <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接口的包路径 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.example.pet.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>
 
</beans>

PetController.java（Spring MVC控制器）

package com.example.pet.controller;
 
import com.example.pet.entity.Pet;
import com.example.pet.service.PetService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
 
@Controller
@RequestMapping("/pet")
public class PetController {
 
    @Autowired
    private PetService petService;
 
    @GetMapping("/list")
    public String list(Model model) {
        model.addAttribute("pets", petService.findAll());
        return "petList";
