springcloud alibaba集成kenif4j

以下是Spring Cloud Alibaba集成Knife4j的步骤：

1.在pom.xml文件中添加Knife4j和Swagger的依赖：

<!-- Knife4j -->
<dependency>
    <groupId>com.github.xiaoymin</groupId>
    <artifactId>knife4j-spring-boot-starter</artifactId>
    <version>3.0.2</version>
</dependency>
<!-- Swagger -->
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>2.9.2</version>
</dependency>
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger-ui</artifactId>
    <version>2.9.2</version>
</dependency>

2.在启动类上添加注解@EnableSwagger2和@EnableKnife4j：

@SpringBootApplication
@EnableSwagger2
@EnableKnife4j
public class DemoApplication {
    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

3.在配置文件中添加Swagger和Knife4j的配置：

# Swagger配置
swagger:
  enabled: true
  title: Demo API
  description: Demo API文档
  version: 1.0
  base-package: com.example.demo.controller
  contact:
    name: demo
    url: https://www.example.com
    email: demo@example.com

# Knife4j配置
knife4j:
  enabled: true
  title: Demo API
  description: Demo API文档
  version: 1.0
  base-package: com.example.demo.controller
  contact:
    name: demo
    url: https://www.example.com
    email: demo@example.com

4.在Controller类上添加Swagger注解：

@RestController
@Api(tags = "DemoController", description = "Demo接口")
public class DemoController {
    @ApiOperation(value = "获取用户信息", notes = "根据用户ID获取用户信息")
    @ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long")
    @GetMapping("/user/{id}")
    public User getUser(@PathVariable Long id) {
        // ...
    }
}

5.启动应用程序并访问http://localhost:port/doc.html，即可查看Knife4j生成的API文档。
