1、添加依赖

在pom.xml 文件中添加 knife4j-spring-boot-starter 的依赖

<dependency>  
    <groupId>com.github.xiaoymin</groupId>  
    <artifactId>knife4j-spring-boot-starter</artifactId>  
    <version>3.0.3</version>  
</dependency>

2、配置

# application.yml  
knife4j:  
  enable: true # 开启Knife4j增强功能  
  base-package: com.xxx.xxx.controller # 设置需要扫描的包路径

3、使用Swagger注解

为实体类添加@ApiModel注解和ApiModelProperty注解
例如：

@ApiModel("用户实体类")
@Data
@TableName("employee")
public class Employee implements Serializable {

    @ApiModelProperty("用户Id")
    @TableField(value = "id", select = false)
    @TableId(type = IdType.ASSIGN_ID)
    private Long id;

    @ApiModelProperty("用户名称")
    private String name;

    @ApiModelProperty("用户密码")
    private String password;

    @TableField(value = "create_time",fill = FieldFill.INSERT)
    @JsonFormat(pattern="yyyy-MM-dd HH:mm:ss",timezone="GMT+8")
    private LocalDateTime createTime;

    @TableField(value = "update_time",fill = FieldFill.INSERT_UPDATE)
    @JsonFormat(pattern="yyyy-MM-dd HH:mm:ss",timezone="GMT+8")
    private LocalDateTime updateTime;
}

在 Controller 类和方法上使用 Swagger 的注解来描述 API

@Api(tags = "示例接口")  
@RestController  
@RequestMapping("/example")  
public class ExampleController {  
  
    @ApiOperation("获取示例数据")  
    @GetMapping("/data")  
    public String getData() {  
        return "示例数据";  
    }  
}

4、定义API文档的标题、描述、版本等信息

创建配置类 SwaggerConfig ：

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
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;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.any())
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfo(
                "你的API标题", // title
                "你的API描述", // description
                "1.0", // version
                "Terms of service", // termsOfServiceUrl
                "你的联系人名字", // contact
                "你的API许可证", // license
                "你的API许可证URL" // licenseUrl
        );
    }
}
