Springboot整合Knife4j接口文档

Spring Boot整合Knife4j创建Swagger接口文档的步骤如下：

1. 在pom.xml中添加Knife4j的依赖：

<dependency>
    <groupId>com.github.xiaoymin</groupId>
    <artifactId>knife4j-spring-boot-starter</artifactId>
    <version>最新版本号</version>
</dependency>

2. 在application.yml或application.properties中配置Knife4j相关的属性（可选）：

# 配置Knife4j的相关属性，例如标题、描述等
knife4j:
  basic:
    enable: true
  doc-title: "接口文档标题"
  doc-description: "接口文档描述"

3. 在Spring Boot启动类上添加@EnableKnife4j注解启用Knife4j：

import com.github.xiaoymin.knife4j.spring.annotations.EnableKnife4j;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
 
@SpringBootApplication
@EnableKnife4j // 启用Knife4j
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

4. 使用Swagger注解标注Controller和方法：

import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
 
@RestController
@RequestMapping("/api/demo")
@Api(tags = "示例接口")
public class DemoController {
 
    @GetMapping("/greet")
    @ApiOperation("问候接口")
    public String greet() {
        return "Hello, Knife4j!";
    }
}

完成以上步骤后，重启Spring Boot应用，访问http://<host>:<port>/doc.html即可看到Knife4j生成的Swagger接口文档。
