SpringBoot整合swagger-ui并修改访问路径

用该方法之前要看一下自己swagger的版本,我一开始用的时候，就是因为版本的问题而出错

这是我的maven引用

    io.springfox
	springfox-swagger2
	2.9.2



	io.springfox
	springfox-swagger-ui
	2.9.2

如果想加上标题之类的,下面的这些也可以放进上面的类中

    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                //controller的目录
                .apis(RequestHandlerSelectors.basePackage("com.swagger.api"))
                .paths(PathSelectors.any())
                .build();
    }
	//用来创建该Api的基本信息（这些基本信息会展现在文档页面中）
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("swagger")
                .description("http://www.baidu.com/")
                .termsOfServiceUrl("http://www.baidu.com/")
                .version("1.0")
                .build();
    }
