添加Swagger2依赖
在pom.xml中加入Swagger2的依赖
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>2.2.2</version>
</dependency>
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>2.2.2</version>
</dependency>
创建Swagger2配置类
在Application.java同级创建Swagger2的配置类Swagger2。
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;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
@Configuration
@EnableSwagger2
public class Swagger2 {
@Bean
public Docket createRestApi() {
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
.apis(RequestHandlerSelectors.basePackage("你自己的外部接口包名称"))
.paths(PathSelectors.any())
.build();
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("词网Neo4j RESTful APIs")
.description("The Neo4j RESTful APIs description/")
.termsOfServiceUrl("")
.contact("李庆海")
.version("5.0")
.build();
}
}
添加文档内容
在完成了上述配置后,其实已经可以生产文档内容,但是这样的文档主要针对请求本身,而描述主要来源于函数等命名产生,对用户并不友好,我们通常需要自己增加一些说明来丰富文档内容。
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import io.swagger.annotations.ApiParam;
/**
* 系统用户Controller
*
* @author 李庆海
*
*/
@Api(value = "系统用户接口", tags = "系统管理")
@RestController
@RequestMapping("/v3/edu/users")
public class UserController {
@Autowired
private UserService userService;
/**
* 添加用户,注册
*
* @param loginName
* 登录账号
* @param userName
* 用户名称
* @param password
* 登录密码
* @param roleId
* 用户角色
* @return
* @throws ResourceExistsException
*/
@ApiOperation(value = "添加用户")
@PostMapping("/")
public JsonResult create(
@ApiParam(name = "loginName", value = "登录账号", required = true) @RequestParam(required = true) @RequestBody String loginName,
@ApiParam(name = "userName", value = "用户名称", required = true) @RequestParam(required = true) @RequestBody String userName,
@ApiParam(name = "password", value = "登录密码", required = true) @RequestParam(required = true) @RequestBody String password,
@ApiParam(name = "roleId", value = "用户角色编号", required = true) @RequestParam(required = true) @RequestBody String roleId)
throws ResourceExistsException {
boolean exists = this.userService.exists(loginName);
if (exists) {
throw new ResourceExistsException(loginName);
}
User user = userService.create(loginName, password, userName, roleId);
return new JsonResult(user);
}
}
查看API
启动Spring Boot程序,访问:http://localhost:8080/swagger-ui.html
微信截图_20180106154957.pngAPI文档访问与调试
Swagger除了查看接口功能外,还提供了调试测试功能,我们可以点击上图中右侧的Model Schema(黄色区域:它指明了数据结构),此时Value中就有了user对象的模板,我们只需要稍适修改,点击下方Try it out!按钮,即可完成了一次请求调用!可以通过几个GET请求来验证之前的POST请求是否正确。
