knif4j是什么，和swagger是什么关系

Knif4j 是一个基于 SpringBoot 和 Swagger 的 Java 接口文档生成工具。Swagger 是一个用于设计、构建和文档化 RESTful 接口的开源工具集，它提供了一种简单的方式来描述和定义 RESTful 接口，使得开发者能够轻松地生成可视化的 API 文档。而 Knif4j 则是在 Swagger 的基础上进行了一些拓展和优化，提供了更加便捷的接口文档生成和管理功能，使得接口文档的编写和维护更加高效和易用。因此，Knif4j 可以看作是 Swagger 的一个增强版，提供了更多功能和特性。

spingboot整合knif4j

Spring Boot整合Knife4j可以快速生成API接口文档，可以让前后端更好的协作，提高开发效率。下面是整合步骤：

1. 引入依赖

在pom.xml文件中添加Knife4j的依赖：

<dependency>
    <groupId>com.github.xiaoymin</groupId>
    <artifactId>knife4j-spring-boot-starter</artifactId>
    <version>2.0.2</version>
</dependency>

2. 配置Swagger

在Spring Boot启动类上添加@EnableSwagger2注解开启Swagger，示例代码如下：

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

3. 配置Knife4j

在application.properties文件中配置Knife4j的相关属性，示例代码如下：

# 设置Knife4j文档页面的标题
spring.application.name=Demo

# 配置Knife4j的访问路径
springfox.documentation.swagger.v2.path=/api-docs

# 配置Knife4j的UI页面访问路径
knife4j.swagger-ui.path=/doc.html

4. 编写API文档

在Controller类上使用Swagger注解编写API文档，示例代码如下：

@RestController
@RequestMapping("/user")
@Api(tags = "用户管理")
public class UserController {

    @ApiOperation(value = "获取用户列表", notes = "获取所有用户列表")
    @GetMapping("/")
    public List<User> list() {
        // ...
    }

    @ApiOperation(value = "创建用户", notes = "根据User对象创建用户")
    @PostMapping("/")
    public String create(@RequestBody User user) {
        // ...
    }

    @ApiOperation(value = "更新用户", notes = "根据User对象更新用户")
    @PutMapping("/")
    public String update(@RequestBody User user) {
        // ...
    }

    @ApiOperation(value = "删除用户", notes = "根据用户ID删除用户")
    @DeleteMapping("/{id}")
    public String delete(@PathVariable Long id) {
        // ...
    }
}

5. 查看API文档

启动Spring Boot应用程序后，访问http://localhost:8080/doc.html即可查看API文档页面。

以上就是Spring Boot整合Knife4j的步骤，希望对你有所帮助。

springboot集成knif4j

Sure! To integrate Spring Boot with Knife4j, you can follow these steps:

1. Add the required dependencies to your project's `pom.xml` file:

<dependency>
    <groupId>com.github.xiaoymin</groupId>
    <artifactId>knife4j-spring-boot-starter</artifactId>
    <version>2.0.2</version>
</dependency>

2. Create a new configuration class, typically named `SwaggerConfiguration`, and annotate it with `@Configuration`:

@Configuration
public class SwaggerConfiguration {
    
}

3. Inside the `SwaggerConfiguration` class, add the necessary bean definitions for `Docket` and `ApiInfo`:

@Configuration
public class SwaggerConfiguration {
    
    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)
            .apiInfo(apiInfo())
            .select()
            .apis(RequestHandlerSelectors.basePackage("com.example.controller")) // Set your controller package
            .paths(PathSelectors.any())
            .build();
    }
    
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
            .title("Your API Documentation")
            .description("Description of your API")
            .version("1.0.0")
            .build();
    }
    
}

4. Make sure to update the `basePackage` value in the `RequestHandlerSelectors` to match the package where your Spring MVC controllers are located.

5. Run your Spring Boot application, and you should be able to access the Knife4j swagger UI at `http://localhost:8080/doc.html`, where `8080` is your application's port.

That's it! You have now integrated Knife4j with your Spring Boot application. You can customize the Swagger configuration further according to your requirements.
