SpringBoot学习（八）——Swagger

导入依赖

    org.springframework.boot
    spring-boot-starter-web


    io.springfox
    springfox-boot-starter
    3.0.0

创建HelloController

@RestController
public class HelloController {
    @RequestMapping("/hello")
    public String hello(){
        return "hello";
    }
}

@Configuration
@EnableSwagger2
public class SwaggerConfig {
}

在启动项目时报错，Failed to start bean ‘documentationPluginsBootstrapper

在application.properties中添加

spring.mvc.pathmatch.matching-strategy=ant_path_matcher

启动项目，访问http://localhost:8080/swagger-ui/index.html

@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Bean
    public Docket docket(){
        return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo());
    }

    private ApiInfo apiInfo(){
        Contact contact = new Contact("阿强", "https://blog.csdn.net/qq_41505957", "1758043090@qq.com");
        return new ApiInfo("我的API文档",
                "阿强的swagger文档",
                "v1.0",
                "https://blog.csdn.net/qq_41505957",// 自己的团队组织网站
                contact,
                "Apache 2.0",
                "http://www.apache.org/licenses/LICENSE-2.0",
                new ArrayList<>()
        );

    }
}

public Docket docket(){
    return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).
            select().
            apis(RequestHandlerSelectors.basePackage("com.example.demo.controller")).
            build();
}

使用groupName()为api文档分组。

当想创建多个分组时，需要创建多个Docket Bean

@Bean
public Docket docket(){
    return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).
            groupName("阿强").
            select().
            apis(RequestHandlerSelectors.basePackage("com.example.demo.controller")).
            build();
}

@Bean
public Docket docket1(){
    return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).
            groupName("A");

}

@Bean
public Docket docket2(){
    return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).
            groupName("B");

}
@Bean
public Docket docket3(){
    return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).
            groupName("C");

}

创建一个实体类，@ApiModel用于实体类上

@ApiModelProperty用于实体类属性上

@ApiModel("用户实体类")
public class User {
    @ApiModelProperty("用户名")
    private String userName;
    @ApiModelProperty("密码")
    private String passWord;
    public User(String userName, String passWord) {
        this.userName = userName;
        this.passWord = passWord;
    }
}

当实体类作为方法的返回值时，文档中会有实体类的说明

@GetMapping("/getUser")
public User getUser(User user){
    return user;
}
