基于spring boot的宠物领养管理系统代码

基于Spring Boot的宠物领养管理系统是一个典型的Web应用程序，利用Spring Boot框架的快速开发和高效配置特性来实现。以下是一个基本的代码结构和关键组件的介绍： ### 1. 项目结构 ``` pet-adoption-system ├── src │ ├── main │ │ ├── java │ │ │ └── com.example.petadoption │ │ │ ├── controller │ │ │ ├── service │ │ │ ├── repository │ │ │ └── model │ │ └── resources │ │ └── application.properties └── pom.xml ``` ### 2. `pom.xml` ```xml <project xmlns="http://maven.apache.org/POM/4.0.0" ...> <modelVersion>4.0.0</modelVersion> <groupId>com.example</groupId> <artifactId>pet-adoption-system</artifactId> <version>0.0.1-SNAPSHOT</version> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jpa</artifactId> </dependency> <dependency> <groupId>com.h2database</groupId> <artifactId>h2</artifactId> <scope>runtime</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project> ``` ### 3. `application.properties` ```properties spring.datasource.url=jdbc:h2:mem:petdb spring.datasource.driverClassName=org.h2.Driver spring.datasource.username=sa spring.datasource.password= spring.jpa.database-platform=org.hibernate.dialect.H2Dialect spring.h2.console.enabled=true ``` ### 4. `model` 包 ```java package com.example.petadoption.model; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.GenerationType; import javax.persistence.Id; @Entity public class Pet { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id; private String name; private String species; private String breed; private String description; // Getters and Setters } ``` ### 5. `repository` 包 ```java package com.example.petadoption.repository; import com.example.petadoption.model.Pet; import org.springframework.data.jpa.repository.JpaRepository; import org.springframework.stereotype.Repository; @Repository public interface PetRepository extends JpaRepository<Pet, Long> { } ``` ### 6. `service` 包 ```java package com.example.petadoption.service; import com.example.petadoption.model.Pet; import com.example.petadoption.repository.PetRepository; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import java.util.List; import java.util.Optional; @Service public class PetService { @Autowired private PetRepository petRepository; public List<Pet> getAllPets() { return petRepository.findAll(); } public Optional<Pet> getPetById(Long id) { return petRepository.findById(id); } public Pet savePet(Pet pet) { return petRepository.save(pet); } public void deletePet(Long id) { petRepository.deleteById(id); } } ``` ### 7. `controller` 包 ```java package com.example.petadoption.controller; import com.example.petadoption.model.Pet; import com.example.petadoption.service.PetService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.*; import java.util.List; import java.util.Optional; @RestController @RequestMapping("/pets") public class PetController { @Autowired private PetService petService; @GetMapping public List<Pet> getAllPets() { return petService.getAllPets(); } @GetMapping("/{id}") public Optional<Pet> getPetById(@PathVariable Long id) { return petService.getPetById(id); } @PostMapping public Pet savePet(@RequestBody Pet pet) { return petService.savePet(pet); } @DeleteMapping("/{id}") public void deletePet(@PathVariable Long id) { petService.deletePet(id); } } ``` ### 8. 启动类 ```java package com.example.petadoption; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class PetAdoptionApplication { public static void main(String[] args) { SpringApplication.run(PetAdoptionApplication.class, args); } } ``` 通过上述代码结构和关键组件的介绍，你可以快速搭建一个基于Spring Boot的宠物领养管理系统。你可以根据实际需求进一步扩展和优化功能。
