Swagger
前后端分离
Vue + SpringBoot
后端时代:前端只用管理静态页面; html==> 后端。模板引擎JSP =>后端是主力
前后端分离式时代:
●后端:后端控制层，服务层,数据访问层[后端团队]
●前端:前端控制层，视图层[前端团队]
。伪造后端数据，json。 已经存在了，不需要后端，前端工程依旧能够跑起来
●前端后如何交互? ===> API
●前后端相对独立，松耦合;
●前后端甚至可以部署在不同的服务器上;

官网https://swagger.io/
在项目使用Swagger需要springbox;
●swagger2
●ui
SpringBoot集成Swagger
1,新建一个springboot-web项目
2,导入maven
<!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger-ui -->
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>3.0.0</version>
</dependency>
<!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger2 -->
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>3.0.0</version>
</dependency>
spring boot老版本使用以上配置
或者
<!-- https://mvnrepository.com/artifact/io.springfox/springfox-boot-starter -->
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-boot-starter</artifactId>
<version>3.0.0</version>
</dependency>
3.编写一-个Hello工程
4.配置Swagger ==> Config
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import springfox.documentation.oas.annotations.EnableOpenApi;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
@Configuration
@EnableOpenApi
public class SwaggerConfig {
}
访问地址http://localhost:8080/swagger-ui/
使用swagger3出现Failed to start
bean‘documentationPluginsBootstrapper 错误，还可以在application.properties里面加"spring.mvc.pathmatch.matching-strategy= ANT_PATH_MATCHER"
配置Swagger信息
默认调用的是ApiInfo里面的
this.apiInfo = ApiInfo.DEFAULT;
public static final Contact DEFAULT_CONTACT = new Contact("", "", "");
static {
DEFAULT = new ApiInfo("Api Documentation", "Api Documentation", "1.0", "urn:tos", DEFAULT_CONTACT, "Apache 2.0", "http://www.apache.org/licenses/LICENSE-2.0", new ArrayList());
}
@Configuration
@EnableOpenApi
public class SwaggerConfig {
//配置了Swagger的Docker的bean实例,替换默认值 this.apiInfo = ApiInfo.DEFAULT;
/* static {
DEFAULT = new ApiInfo("Api Documentation", "Api Documentation", "1.0", "urn:tos", DEFAULT_CONTACT, "Apache 2.0", "http://www.apache.org/licenses/LICENSE-2.0", new ArrayList());
}*/
@Bean
public Docket docket(){
return new Docket(DocumentationType.OAS_30).apiInfo(apiInfo());
}
//配置Swagger信息=apiInfo
private ApiInfo apiInfo(){
//作者信息
Contact contact = new Contact("陈平安", "urn:tos", "2188671488.com");
return new ApiInfo("陈平安的Swagger API文档",
"有不开心，也有在努力生活",
"1.0",
"urn:tos",
contact,
/* DEFAULT_CONTACT,*/
"Apache 2.0",
"http://www.apache.org/licenses/LICENSE-2.0",
new ArrayList());
}
}
Swagger配置扫描接口
Docket.select()
@Bean
public Docket docket(){
return new Docket(DocumentationType.OAS_30).
apiInfo(apiInfo()).
select()
//requestHandler ->
//RequestHandlerSelectors 配置要扫描接口的方式
//basePackage("")指定扫描的包
//any()扫描全部
//none()都不扫描
//withClassAnnotation 扫描类上的注解 withClassAnnotation.(RestController.class)
//withMethodAnnotation 扫描方法上的注解 withMethodAnnotation.(GetMapping.class)
.
apis(RequestHandlerSelectors.basePackage("com.controller")).
//过滤什么路径
paths(PathSelectors.ant("/com/**")).
build();
}
配置是否启动swagger
@Bean
public Docket docket(){
return new Docket(DocumentationType.OAS_30).
apiInfo(apiInfo()).
enable(true).//enable是否启动swagger, 如果为False, 则swagger不能再浏览器中访问
select()
//requestHandler ->
//RequestHandlerSelectors 配置要扫描接口的方式
//basePackage("")指定扫描的包
//any()扫描全部
//none()都不扫描
//withClassAnnotation 扫描类上的注解 withClassAnnotation.(RestController.class)
//withMethodAnnotation 扫描方法上的注解 withMethodAnnotation.(GetMapping.class)
.
apis(RequestHandlerSelectors.basePackage("com.controller")).
//过滤什么路径
//paths(PathSelectors.ant("/com/**")).
build();
}
我只希望我的Swagger在生产环境中使用，在发布的时候不使用
●判断是不是生产环境flag = false
●注入enable (flag)
@Bean //获取项目环境
public Docket docket(Environment environment){
//设置要显示的Swagger环境
Profiles profiles = Profiles.of("dev","test");
//environment.acceptsProfiles 判断是否处在自己设定的环境当中
boolean flag = environment.acceptsProfiles(profiles);
return new Docket(DocumentationType.OAS_30).
apiInfo(apiInfo()).
//enable(true).//enable是否启动swagger, 如果为False, 则swagger不能再浏览器中访问
enable(flag).
select()
.apis(RequestHandlerSelectors.basePackage("com.controller")).
build();
}
application.properties
spring.profiles.active=dev
applicationdev.properties
server.port=8081
配置API文档分组
groupName("陈平安")
配置多个分组:多个Docket实例既可
@Bean
public Docket docket1(){
return new Docket(DocumentationType.OAS_30).groupName("A");
}
@Bean
public Docket docket2(){
return new Docket(DocumentationType.OAS_30).groupName("B");
}
@Bean
public Docket docket3(){
return new Docket(DocumentationType.OAS_30).groupName("C");
}
实体类配置
@Api(tags = “”)
类注释
@ApiModel(“”)
方法注释
@ApiOperatio
//@Api(注释)
@ApiModel("用户类")
public class User {
@ApiModelProperty("用户名")
public String username;
@ApiModelProperty("密码")
public String password;
}
controller
@Api(tags = "HelloController控制类")
@RestController
public class HelloController {
@GetMapping( value = "/hello")
public String hello(){
return "hello";
}
//只要我们的接口中，返回值中存在实体类，他就会被扫描到swagger中
@GetMapping( value = "/user")
public User user(){
return new User();
}
//Operation接口,不是放在类上的，是方法
// @ApiOperation("hello控制类")
@GetMapping(value = "/hello2")
public String hello2(@ApiParam("用户名") String username){
return "hello" + username;
}
@PostMapping( value = "/postt")
public User postt(@ApiParam("用户名") User user){
return user;
}
