0701~放假总结

今天集成了swagger自动生成模板和注册功能的店铺logo上传,都是以前做过的功能;

swagger自动生成步骤;

1.新建模板类,把swagger配置类的代码放进去;

2.自动生成的路径选好即可;

 1.新建模板类,把swagger配置类的代码放进去;

package cn.itsource.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;


@Configuration
@EnableSwagger2
public class Swagger2 {

    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                //对外暴露服务的包,以controller的方式暴露,所以就是controller的包.
                .apis(RequestHandlerSelectors.basePackage("cn.itsource.controller"))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("系统服务API")
                .description("平台服务接口文档说明")
                .contact(new Contact("colin", "", "wujiangbo@itsource.cn"))
                .version("1.0")
                .build();
    }

}

2.自动生成的路径选好即可; 

//swagger的输出配置
focList.add(new FileOutConfig("/templates/swagger2.java.vm") {
    @Override
    public String outputFile(TableInfo tableInfo) {
        //合并好的内容输出到哪儿？
        return rb.getString("OutputDir")+ "/cn/itsource/config/swagger2.java";
    }
});

 阿里云oss上传步骤;

1.后端代码参考官网,把模板扒下来用;

2.前端记得给name;后端接参数的时候用name的值接即可;

3.后端业务完成后拼接参数,把路径返回给前端展示;

 1.后端代码参考官网,把模板扒下来用;

@Override
public JSONResult getFileOss(MultipartFile file) {
    //文件上传接口（上传到OSS中的bucket）
    // Endpoint：地域节点
    String endpoint = "oss-cn-chengdu.aliyuncs.com";
    // 阿里云账号AccessKey拥有所有API的访问权限，风险很高。强烈建议您创建并使用RAM用户进行API访问或日常运维，请登录RAM控制台创建RAM用户。
    String accessKeyId = "这里填id";
    String accessKeySecret = "这里填密钥";
    // 填写Bucket名称，例如examplebucket。
    String bucketName = "0217blog";

    //获取上传文件的后缀
    String originalFilename = file.getOriginalFilename();//.jpg.jng

    int i = originalFilename.lastIndexOf(".");
    String fileType = originalFilename.substring(i);

    // 填写Object完整路径，完整路径中不能包含Bucket名称，例如exampledir/exampleobject.txt。
    //
    String fileName = UUID.randomUUID().toString().replace("-", "") + fileType;

    // 创建OSSClient实例。
    OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);

    try {
        InputStream inputStream = file.getInputStream();
        // 创建PutObject请求。
        ossClient.putObject(bucketName, fileName, inputStream);

    } catch (OSSException oe) {
        System.out.println("Caught an OSSException, which means your request made it to OSS, "
                + "but was rejected with an error response for some reason.");
        System.out.println("Error Message:" + oe.getErrorMessage());
        System.out.println("Error Code:" + oe.getErrorCode());
        System.out.println("Request ID:" + oe.getRequestId());
        System.out.println("Host ID:" + oe.getHostId());
    } catch (Exception ce) {
        System.out.println("上传文件OSS异常：" + ce.getMessage());
        return JSONResult.error(ce.getMessage());
    } finally {
        if (ossClient != null) {
            ossClient.shutdown();
        }
    }
    //拼接URL地址返回给前端
    //https://blog0217.oss-cn-chengdu.aliyuncs.com/77786f3d6f31445bad462e5464085de8.jpg
    String url = "https://" + bucketName + "." + endpoint + "/" + fileName;
    return JSONResult.success(url);

 2.前端记得给name;后端接参数的时候用name的值接即可;

@RequestMapping("/file")
public JSONResult fileOss(@RequestParam("fileName") MultipartFile file){

    return iFileService.getFileOss(file);
}

  点击上传
  只能上传jpg/png文件，且不超过500kb

这里的name要与后端接口的接收参数保持一致;

 3.后端业务完成后拼接参数,把路径返回给前端展示;

//拼接URL地址返回给前端 //https://blog0217.oss-cn-chengdu.aliyuncs.com/77786f3d6f31445bad462e5464085de8.jpg

String url = "https://" + bucketName + "." + endpoint + "/" + fileName;

   return JSONResult.success(url);
