1、新增相關依賴
<!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger2 -->
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>2.9.2</version>
</dependency>
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>2.9.2</version>
</dependency>
2、建立Swagger自動配置類
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 Swagger {
@Bean
public Docket createRestApi() {
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
.apis(RequestHandlerSelectors.basePackage("com.ck.demo"))
.paths(PathSelectors.any())
.build();
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("Spring Boot中使用Swagger2構建RESTful APIs")
.description("更多Spring Boot相關文章請關注:https://www.yuque.com/chaohen")
.termsOfServiceUrl("https://www.yuque.com/chaohen")
.contact("潮痕")
.version("1.0.0")
.build();
}
}
- 首先通過
@Configuration
註解,讓Spring來載入該類配置。再通過@EnableSwagger2
註解來啟用Swagger2。 - 其次通過
createRestApi
函式建立Docket
的Bean之後,使用apiInfo()
用來建立該Api的基本資訊(這些基本資訊會展現在文件頁面中)。- - 再次通過
select()
函式返回一個ApiSelectorBuilder
例項用來控制哪些介面暴露給Swagger來展現,本例採用指定掃描的包路徑來定義,Swagger會掃描該包下所有Controller定義的API,併產生文件內容,這裡除了被@ApiIgnore
指定的請求。
實際使用:
import com.ck.demo.bean.BlogsUserInfo;
import com.ck.demo.service.UserInfoService;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiOperation;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.BeanPropertyRowMapper;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.core.RowMapper;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;
import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import java.util.List;
@RestController
@RequestMapping("user")
public class UsreInfoController {
@Resource
private JdbcTemplate jdbcTemplate;
@Autowired
private UserInfoService userInfoService;
@ApiOperation(value = "獲取使用者列表",notes = "")
@RequestMapping(value = "/getusers",method = RequestMethod.GET)
public Object getDbType() {
String sql = "select * from blogs_user_info";
RowMapper<BlogsUserInfo> rowMapper = new BeanPropertyRowMapper<BlogsUserInfo>(BlogsUserInfo.class);
List<BlogsUserInfo> list = jdbcTemplate.query(sql, rowMapper);
ServletRequestAttributes servletRequestAttributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
HttpServletRequest request = servletRequestAttributes.getRequest();
Integer times = (Integer) request.getSession().getAttribute("times");
;
if (times == null) {
times = new Integer(1);
} else {
times = new Integer(times.intValue() + 1);
}
request.getSession().setAttribute("times", times);
System.out.println("***********************" + times);
return list;
}
@ApiOperation(value = "根據使用者ID獲取使用者資訊",notes = "")
@ApiImplicitParam(name = "id", value = "使用者ID", required = true, dataType = "Long")
@RequestMapping("/getId/{id}")
public Object getUserInfoByParmityKey(@PathVariable String id) {
BlogsUserInfo blogsUserInfo = userInfoService.getUserInfoByParmityKeyService(id);
return blogsUserInfo;
}
}
註解語法用例:
@Api:用在請求的類上,表示對類的說明
tags="說明該類的作用,可以在UI介面上看到的註解"
value="該引數沒什麼意義,在UI介面上也看到,所以不需要配置"
eg: @Api(tags = "使用者資訊Controller")
@ApiOperation:用在請求的方法上,說明方法的用途、作用
value="說明方法的用途、作用"
notes="方法的備註說明"
eg: @ApiOperation(value="使用者登入",notes="手機號、密碼都是必填!")
@ApiImplicitParams:用在請求的方法上,表示一組引數說明
@ApiImplicitParam:用在@ApiImplicitParams註解中,指定一個請求引數的各個方面
name:引數名
value:引數的漢字說明、解釋
required:引數是否必須傳
paramType:引數放在哪個地方
· header --> 請求引數的獲取:@RequestHeader
· query --> 請求引數的獲取:@RequestParam
· path(用於restful介面)--> 請求引數的獲取:@PathVariable
· body(不常用)
· form(不常用)
dataType:引數型別,預設String,其它值dataType="Integer"
defaultValue:引數的預設值
eg: @ApiImplicitParams({
@ApiImplicitParam(name="username",value="使用者名稱",required=true,paramType="String"),
@ApiImplicitParam(name="password",value="密碼",required=true,paramType="form"),
@ApiImplicitParam(name="vcode",value="驗證碼",required=true,paramType="form",dataType="Integer")
})
@ApiResponses:用在請求的方法上,表示一組響應
@ApiResponse:用在@ApiResponses中,一般用於表達一個錯誤的響應資訊
code:數字,例如400
message:資訊,例如"請求引數沒填好"
response:丟擲異常的類
eg:@ApiOperation(value = "select1請求",notes = "多個引數,多種的查詢引數型別")
@ApiResponses({
@ApiResponse(code=400,message="請求引數沒填好"),
@ApiResponse(code=404,message="請求路徑沒有或頁面跳轉路徑不對")
})
@ApiModel:用於響應類上,表示一個返回響應資料的資訊
(這種一般用在post建立的時候,使用@RequestBody這樣的場景,
請求引數無法使用@ApiImplicitParam註解進行描述的時候)
@ApiModelProperty:用在屬性上,描述響應類的屬性
eg:
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import java.io.Serializable;
@ApiModel(description= "返回響應資料")
public class RestMessage implements Serializable{
@ApiModelProperty(value = "是否成功")
private boolean success=true;
@ApiModelProperty(value = "返回物件")
private Object data;
@ApiModelProperty(value = "錯誤編號")
private Integer errCode;
@ApiModelProperty(value = "錯誤資訊")
private String message;
/* getter/setter */
}
3、在Swagger視覺化介面展示
輸入 http://localhost:8080/user/getusers 結果如下:
{"uuid":"d882f714-c015-4c46-a92e-5d7e2a8b3380","name":"丫丫","age":12,"address":"浙江省","phone":"1898*****63","company":"alibaba"}
在瀏覽器開啟:http://localhost:8080/swagger-ui.html
頁面如下:
get請求
post請求
delete請求
4、詳情測試
get請求測試:
post請求測試
此時執行成功,已經達到所需的目標,End。
