今天給大家?guī)淼氖顷P(guān)于Java的相關(guān)知識(shí),文章圍繞著java如何集成swagger組件展開,文中有非常詳細(xì)的介紹及代碼示例,需要的朋友可以參考下

一：簡(jiǎn)介

Swagger 是一個(gè)規(guī)范和完整的框架，用于生成、描述、調(diào)用和可視化 RESTful 風(fēng)格的 Web 服務(wù)?？傮w目標(biāo)是使客戶端和文件系統(tǒng)作為服務(wù)器以同樣的速度來更新。文件的方法，參數(shù)和模型緊密集成到服務(wù)器端的代碼，允許API來始終保持同步。Swagger 讓部署管理和使用功能強(qiáng)大的API從未如此簡(jiǎn)單。

二：集成swagger

1.引入pom.xml文件包（導(dǎo)入4個(gè)jar包）

注意：jdk1.8以上才能運(yùn)行swagger2

<!--swagger-->
	 <dependency>
	     <groupId>io.springfox</groupId>
	     <artifactId>springfox-swagger2</artifactId>
	     <version>2.8.0</version>
	 </dependency>
	 <!--swagger-ui-->
	 <dependency>
	     <groupId>io.springfox</groupId>
	     <artifactId>springfox-swagger-ui</artifactId>
	     <version>2.8.0</version>
	 </dependency>
	 <!--swagger-ui增強(qiáng)-->
	 <dependency>
	     <groupId>com.github.xiaoymin</groupId>
	     <artifactId>knife4j-spring-boot-starter</artifactId>
	     <version>2.0.4</version>
	 </dependency>
	 <!--swagger-xml bind-->
	 <dependency>
	     <groupId>javax.xml.bind</groupId>
	     <artifactId>jaxb-api</artifactId>
	     <version>2.3.0</version>
	 </dependency>

2.要想使用Swagger，必須編寫一個(gè)配置類來配置 Swagger，這里的配置類如下

@Configuration
@EnableSwagger2
public class SwaggerConfig {
    private String title = "標(biāo)題..";
    private String description = "";
    private String termsOfServiceUrl = "";
    private String version = "版本號(hào)..";

    @Bean
    public Docket createDefaultRestApi() {
        return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).select()
                .apis(RequestHandlerSelectors.withClassAnnotation(Api.class))
                .apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class)).paths(PathSelectors.any())
                .build().groupName("default").securitySchemes(securitySchemes()).securityContexts(securityContexts());
    }

    @Bean
    public Docket createTestRestApi() {
        return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).select()
                .apis(RequestHandlerSelectors.withClassAnnotation(Api.class))
                .apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class))
                .paths(PathSelectors.ant("/test/**")).build().groupName("測(cè)試/調(diào)試").securitySchemes(securitySchemes())
                .securityContexts(securityContexts());
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder().title(title).description(description).termsOfServiceUrl(termsOfServiceUrl)
                .version(version).build();
    }

    private List<SecurityReference> defaultAuth() {
        AuthorizationScope authorizationScope = new AuthorizationScope("global", "accessEverything");
        AuthorizationScope[] authorizationScopes = new AuthorizationScope[1];
        authorizationScopes[0] = authorizationScope;
        return newArrayList(new SecurityReference("token", authorizationScopes));
    }

    private List<SecurityContext> securityContexts() {
        return newArrayList(SecurityContext.builder().securityReferences(defaultAuth())
                .forPaths(PathSelectors.regex("^(?!auth).*$")).build());
    }

    private List<ApiKey> securitySchemes() {
        return newArrayList(new ApiKey("token", "token", "header"));
    }
}

3.集成RESTful風(fēng)格接口示例

@Api(tags = "測(cè)試")
@RestController
public class TestController {

    @ApiOperation("get方法")
    @GetMapping("getInfo")
    public void getInfo(){
       
    }
}

4.控制臺(tái)打印路徑地址（可選配置）

@Slf4j
@SpringBootApplication
public class SpringbootApplication implements ApplicationRunner {

    public static void main(String[] args) {
        SpringApplication.run(SpringbootApplication.class, args);
    }

    @Autowired
    Environment environment;

    @Override
    public void run(ApplicationArguments args) throws Exception {
        log.info("項(xiàng)目已啟動(dòng)，端口：" + environment.getProperty("local.server.port"));
        log.info("swagger文檔地址：http://localhost:" + environment.getProperty("local.server.port") + "/swagger-ui.html");
        log.info("swagger文檔地址：http://localhost:" + environment.getProperty("local.server.port") + "/doc.html");
    }
}
