接上一项目【springboot】简易模块化开发项目整合MyBatis-plus，进行拓展项目

1.新建模块

右键项目→New→Module，新建一个模块

在这里插入图片描述

父项目选择fast-demo，命名为fast-demo-config，用于存放所有配置项

添加后，项目结构如图

2.添加swagger依赖

fast-demo-config模块的pom.xml中添加swagger依赖

    <dependencies><dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger-ui</artifactId><version>2.8.0</version></dependency><dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger2</artifactId><version>2.8.0</version></dependency><dependency><groupId>javax.xml.bind</groupId><artifactId>jaxb-api</artifactId><version>2.3.0</version></dependency></dependencies>

在fast-demo-config模块新建SwaggerConfig类，用于配置swagger相关设置，配置内容如下

@Configuration
@EnableSwagger2
@ConditionalOnProperty(name = "swagger.enable", havingValue = "true")
public class SwaggerConfig {public Docket createRestApi(){return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).select()// 这里填写的是controller层的路径，填写自己的.apis(RequestHandlerSelectors.basePackage("com.cyfy.fastdemo.controller")).paths(PathSelectors.any()).build();}private ApiInfo apiInfo(){return new ApiInfoBuilder().title("页面标题").contact(new Contact("创建人名称","项目路径","邮箱")).version("版本号").description("描述").build();}
}

项目结构如图

3.swagger测试

fast-demo-web模块中导入fast-demo-config模块

		<dependency><groupId>com.cyfy</groupId><artifactId>fast-demo-config</artifactId><version>0.0.1-SNAPSHOT</version></dependency>

进入application.yml配置文件中，增加如下字段

swagger:enable: true

进入fast-demo-web模块中d UserController类中，增加swagger注解内容

@RestController
@Api("用户信息接口")
public class UserController {@Autowiredprivate UserService userService;@RequestMapping("/user")@ApiOperation(value = "获取所有用户信息", notes = "返回用户信息")public List<User> getUserList(){return userService.getUserList();}
}

运行项目后，浏览器输入http://localhost:8080/swagger-ui.html，便可查看到相关接口文档
