springboot3整合knife4j详细版，包会！

Spring Boot 3整合Knife4j的步骤大致如下：

1. 在pom.xml中添加Knife4j的依赖：

<dependency>
    <groupId>com.github.xiaoymin</groupId>
    <artifactId>knife4j-spring-boot-starter</artifactId>
    <version>3.x.x</version>
</dependency>

2. 配置Knife4j属性，通常在application.yml或application.properties中：

knife4j:
  enable: true
  # 其他可选配置

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

4. 创建Swagger配置类（如果需要自定义配置）：

import com.github.xiaoymin.knife4j.spring.annotations.EnableKnife4j;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
 
@Configuration
@EnableKnife4j
public class SwaggerConfig {
 
    @Bean(value = "defaultApi2")
    public Docket defaultApi2() {
        Docket docket=new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.example.yourproject.controller"))
                .paths(PathSelectors.any())
                .build();
        return docket;
    }
 
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("Knife4j 测试")
                .description("Knife4j 测试接口文档")
                .version("1.0")
                .build();
    }
}

5. 在Controller类中使用Swagger注解标注API：

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;
 
@Api(tags = "测试控制器")
@RestController
@RequestMapping("/test")
public class TestContr
