springboot3整和swagger

要整合Swagger和Spring Boot，需要进行以下步骤：

1. 在pom.xml文件中添加Swagger依赖：

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>3.0.0</version>
</dependency>
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger-ui</artifactId>
    <version>3.0.0</version>
</dependency>

2. 创建Swagger配置类，用于配置Swagger的基本信息和扫描的包路径：

@Configuration
@EnableSwagger2
public class SwaggerConfig {
    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.example.demo.controller"))
                .paths(PathSelectors.any())
                .build()
                .apiInfo(apiInfo());
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("Spring Boot REST API")
                .description("Spring Boot REST API for Online Store")
                .version("1.0.0")
                .build();
    }
}

3. 在Controller类中添加Swagger注解，用于描述接口信息：

@RestController
@RequestMapping("/api")
@Api(value = "onlineStore", description = "Operations pertaining to products in Online Store")
public class ProductController {

    @Autowired
    private ProductService productService;

    @ApiOperation(value = "View a list of available products", response = List.class)
    @GetMapping("/products")
    public List<Product> getAllProducts() {
        return productService.getAllProducts();
    }

    @ApiOperation(value = "Get a product by Id")
    @GetMapping("/products/{id}")
    public Product getProductById(@PathVariable(value = "id") Long productId) {
        return productService.getProductById(productId);
    }

    @ApiOperation(value = "Add a product")
    @PostMapping("/products")
    public Product addProduct(@RequestBody Product product) {
        return productService.addProduct(product);
    }

    @ApiOperation(value = "Update a product")
    @PutMapping("/products/{id}")
    public Product updateProduct(@PathVariable(value = "id") Long productId, @RequestBody Product productDetails) {
        return productService.updateProduct(productId, productDetails);
    }

    @ApiOperation(value = "Delete a product")
    @DeleteMapping("/products/{id}")
    public ResponseEntity<?> deleteProduct(@PathVariable(value = "id") Long productId) {
        productService.deleteProduct(productId);
        return ResponseEntity.ok().build();
    }
}

4. 启动Spring Boot应用程序，访问http://localhost:8080/swagger-ui.html，即可查看Swagger UI界面。
