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("http://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：
http://localhost:8080/swagger-ui.html
以上是SpringBoot基于Swagger2怎么构建API文档的详细内容。更多信息请关注PHP中文网其他相关文章！
