Spring集成swagger步驟(包含Header)

1、添加依賴，2.4.0：

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>${springfox.version}</version>
</dependency>
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger-ui</artifactId>
    <version>${springfox.version}</version>
</dependency>
<dependency>
    <artifactId>classmate</artifactId>
    <groupId>com.fasterxml</groupId>
    <version>1.3.3</version>
</dependency>

　　

2、swagger配置：

@Configuration
@EnableSwagger2
@EnableWebMvc
public class SwaggerConfigure extends WebMvcConfigurerAdapter {

    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
            .genericModelSubstitutes(DeferredResult.class)
            .useDefaultResponseMessages(false)
            .forCodeGeneration(true)
            .pathMapping("")
            .select()
            .apis(RequestHandlerSelectors.basePackage("com.xxx.controller"))
            .paths(PathSelectors.any())
            .build().apiInfo(apiInfo());
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder().title("API文檔").description("API文檔").termsOfServiceUrl(
            "http://localhost:8080/api")
            .contact(new Contact("[e-mail]",
                                 "http://www.cnblogs.com/qiang-cnblog",
                                 "[e-mail]")).version("2.0").build();
    }

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("**/**").addResourceLocations("classpath:/META-INF/resources/");
        registry.addResourceHandler("swagger-ui.html").addResourceLocations("classpath:/META-INF/resources/");
        registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
    }

}

3、web.xml中spring servlet mapping路徑必須包含/，否則不能加載某些資源，導致各種失敗（Important）

<servlet>
    <servlet-name>webapp</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value></param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>webapp</servlet-name>
    <url-pattern>/api/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>webapp</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

　　

4、某些資源文件可能被攔截器攔截，需過濾掉，比如：

"/swagger-resources"
"/v2/api-docs"
"/configuration/ui"

　　

補充：增加Header默認參數

    @Bean
    public Docket createRestApi() {
        ParameterBuilder parameterBuilder = new ParameterBuilder();
        List<Parameter> parameters = new ArrayList<Parameter>();
        parameterBuilder.name("Authentication")
            .description("token")
            .modelRef(new ModelRef("string"))
            .parameterType("header")
            .required(false).build();
        parameters.add(parameterBuilder.build());

        return new Docket(DocumentationType.SWAGGER_2)
            .genericModelSubstitutes(DeferredResult.class)
            .useDefaultResponseMessages(false)
            .forCodeGeneration(true)
            .pathMapping("")
            .select()
            .apis(RequestHandlerSelectors.basePackage("com.xxx.controller"))
            .paths(PathSelectors.any())
            .build()
            .globalOperationParameters(parameters)
            .apiInfo(apiInfo());
    }

　　

效果：
