Summary
This article designs and implements a pet trading management system applet based on the SSM framework. As a growing industry, pet trading requires an efficient, safe, and easy-to-use management system to meet users' needs for pet purchase, transaction, and information management. For this purpose, we chose to use the SSM framework, which integrates Spring, SpringMVC and MyBatis to provide a comprehensive solution.
In the system requirements analysis stage, we clearly defined the functional requirements of the system, including pet information management, user registration and login, pet trading and order management, etc. At the same time, we have divided user roles to ensure the security and rationality of the system. In terms of technology selection, we compared a variety of technical solutions and finally selected the SSM framework based on its maturity, stability and flexibility.
In the system design, we elaborated on the system's architectural design, including the module division of front-end and back-end. In terms of database design, we designed a clear table structure and relationships to support the data operation requirements of the system. In the system implementation, we show the key code snippets, including the code of the controller, service and persistence layer, and also introduce the technologies used in the front end.
Finally, through the user manual and deployment instructions, we provide the system usage and deployment steps. In the summary, we summarize our experience in system design and implementation, and look forward to possible future improvements and expansion directions.

Backend code implementation:
Controller layer
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
@RestController
@RequestMapping("/pet")
public class PetController {
@Autowired
private PetService petService;
@GetMapping("/{petId}")
public Pet getPetById(@PathVariable int petId) {
return petService.getPetById(petId);
}
@PostMapping("/add")
public void addPet(@RequestBody Pet pet) {
petService.addPet(pet);
}
// 其他宠物管理的接口，如更新宠物信息、删除宠物等
}
Service layer
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
@Service
public class PetService {
@Autowired
private PetDao petDao;
public Pet getPetById(int petId) {
return petDao.getPetById(petId);
}
public void addPet(Pet pet) {
petDao.addPet(pet);
}
// 其他宠物管理的业务逻辑，如更新宠物信息、删除宠物等
}
DAO layer
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;
@Mapper
public interface PetDao {
Pet getPetById(@Param("petId") int petId);
void addPet(Pet pet);
// 其他宠物管理的数据库操作，如更新宠物信息、删除宠物等
}
Front-end implementation page code:
<template>
<div>
<h2>宠物列表</h2>
<ul>
<li v-for="pet in pets" :key="pet.petId">
{

</li>
</ul>
</div>
</template>
<script>
export default {
data() {
return {
pets: []
};
},
mounted() {
// 从后端获取宠物列表数据
this.fetchPetList();
},
methods: {
fetchPetList() {
// 调用后端接口获取宠物列表数据
// 可以使用axios或其他HTTP库进行请求
// 示例：axios.get('/pet/list').then(response => { this.pets = response.data; });
}
}
