如何详细解析SpringBoot结合Swagger2构建API文档的步骤？

本文共计508个文字，预计阅读时间需要3分钟。

一、添加依赖--SpringBoot使用Swagger2构建API文档的依赖dependency groupId: io.springfox artifactId: springfox-swagger2 version: 2.7.0/dependencydependency groupId: io.springfox artifactId: springfox-swagger-ui version: 2.7.0/dependency

一、添加依赖

<!--SpringBoot使用Swagger2构建API文档的依赖--> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger2</artifactId> <version>2.7.0</version> </dependency> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger-ui</artifactId> <version>2.7.0</version> </dependency>

二、创建Swagger2配置类

package com.offcn.config; 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; import springfox.documentation.swagger2.annotations.EnableSwagger2; @Configuration//表示该类为一个配置类，相当于spring中的xml配置文件 @EnableSwagger2 //开启在线文档 public class SwaggerConfig { //1.声明 api 文档的属性 private ApiInfo apiInfo() { return new ApiInfoBuilder() .title("Spring Boot中使用Swagger2构建RESTful APIs") .description("优就业") .termsOfServiceUrl("www.ujiuye.com/") .contact("小刘同学") .version("1.0") .build(); } //配置核心配置信息 public Docket createRestApi() { return new Docket(DocumentationType.SWAGGER_2) .apiInfo(apiInfo()) .select() .apis(RequestHandlerSelectors.basePackage("com.offcn.controller")) .paths(PathSelectors.any()) .build(); } }

三、修改Controller 增加文档注释

通过@ApiOperation注解来给API增加说明

通过@ApiImplicitParams@ApiImplicitParam注解来给参数增加说明

package com.offcn.controller; import com.offcn.dao.UserDao; import com.offcn.entity.User; import io.swagger.annotations.ApiImplicitParam; import io.swagger.annotations.ApiImplicitParams; import io.swagger.annotations.ApiOperation; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.DeleteMapping; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; @RequestMapping("/rest") @RestController public class RestFulController { @Autowired private UserDao userDao; @GetMapping("/getUserById") @ApiOperation(value="查找指定id用户信息", notes="根据id查找用户信息") @ApiImplicitParams({ @ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Integer"), }) public User getUserById(Integer id){ User user = userDao.getOne(id); return user; } @DeleteMapping("/del") @ApiOperation(value="删除指定id用户信息", notes="根据id删除用户信息") @ApiImplicitParams({ @ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Integer"), }) public String delUserById(Integer id){ userDao.deleteById(id); return "success"; } }

四、查看Swagger2文档

重启项目

访问：

localhost:8080/swagger-ui.html
