Springboot整合Swagger过程中遇到的坑

       Springboot整合swagger的步骤以及出现问题的解决

第一步：引入swagger的依赖文件：

<dependency>

         <groupId>io.springfox</groupId>

         <artifactId>springfox-swagger2</artifactId>

         <version>2.7.0</version>

  </dependency>

<dependency>

            <groupId>io.springfox</groupId>

            <artifactId>springfox-swagger-ui</artifactId>

            <version>2.7.0</version>

</dependency> 这里的版本为2.7.0。

第二步：写配置文件，纯Java配置。

@Configuration
@EnableSwagger2
public class Swagger2Config {
@Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.xxx.demo.web"))//扫描的是自己写Controller的包名。
                .paths(PathSelectors.any())
                .build();
    }
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("springboot利用swagger构建api文档")//swagger的title
                .description("简单优雅的restfun风格")//自己定义
                .termsOfServiceUrl("http://blog.csdn.net/")//自己定义
                .version("1.0")
                .build();
    }

       这样的话，当自己启动Springboot启动类，然后按照当初自己给的端口(如果自己在配置文件里面配置了访问的时候必须加项目名称，哪自己的记住！)例如我访问的就是：http://localhost:8080/swagger-ui.html。这样就可以看到自己定义的接口了。但如果自己要写测试类测试自己写的接口，按照这种方式配置的swagger，在进行单元测试的时候会报错误。如下：

这时我们只需在我们的测试类上加上@SpringBootApplication  和 @WebAppConfiguration 两个注解，问题解决了。
