將Swagger2與Spring引導應用程序集成時出錯。我堅持這個實現。任何實施或配置問題？Swagger 2與Spring引導應用程序集成
下面是我已經完成整合Swagger2的配置。
SwaggerConfig.java
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
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 SwaggerConfig {
@Bean
public Docket api(){
return new Docket(DocumentationType.SWAGGER_2)
.select()
.apis(RequestHandlerSelectors.any())
.paths(PathSelectors.regex("/api/.*"))
.build()
.apiInfo(apiInfo());
}
@SuppressWarnings("deprecation")
private ApiInfo apiInfo() {
ApiInfo apiInfo = new ApiInfo(
"My Project's REST API",
"This is a description of your API.",
"API TOS",
"[email protected]",
"API License",
"API License URL", null
);
return apiInfo;
}
}
的pom.xml
添加所需的swagger2

application.properties依賴
server.port=10080
server.contextPath=/approot
------------------Hibernate Datasource configuration------------------
spring.datasource.url=${.service.jdbc.url}

當我試圖訪問URL http://localhost:10080/approot/swagger-ui.html時，我得到的錯誤並沒有顯示在網頁上。

您有錯誤，但由於您配置了Spring的錯誤處理方式而沒有看到真正的錯誤。發佈你的Web應用程序配置加上任何東西圍繞錯誤處理。 –
我在application.properties中評論了'error.whitelabel.enabled = false'。現在在後端沒有錯誤。但是我得到了白標籤錯誤頁面。 白標籤錯誤頁面 此應用程序沒有顯式映射/錯誤，因此您將此視爲後備。 Mon Aug 08 12:32:55 BST 2016 有一個意外的錯誤（type = Not Found，status = 404）。 無可用信息 –
