整合Spring Boot 框架集成Knife4j

整合Spring Boot 和 Knife4j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：

# 可以根据需要配置Knife4j的基本属性，例如界面的标题、版本描述等
knife4j.basic.enable=true
knife4j.basic.kt=your-key
knife4j.basic.md=your-secret
knife4j.basic.sign=true

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

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 YourApplication {
    public static void main(String[] args) {
        SpringApplication.run(YourApplication.class, args);
    }
}

4. 在Controller中使用Knife4j提供的@Api和@ApiOperation注解来描述API：

import com.github.xiaoymin.knife4j.annotations.ApiOperationSupport;
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(value = "问候接口", notes = "返回一个简单的问候")
    @ApiOperationSupport(order = 1, ignore = true)
    public String greet() {
        return "Hello, Knife4j!";
    }
}

完成以上步骤后，你的Spring Boot应用将集成了Knife4j，并可以通过Swagger-UI界面查看和测试API。
