Android 上传仓库 本地aar 安卓开发 上传文件

前言：
现在基本不怎么搞安卓的开发了，主要做java开发，在学习各种的框架，由于学校还有项目没搞定，打算改进一下，以前做过原生servlet单文件上传，写的也比较麻烦,大概花了一天的时间,找了一些框架,自己又加调试了一下,做了一个多文件上传,简单记录下。
安卓端：
关联下jar：

dependencies {
    //网络请求相关框架
    compile 'org.xutils:xutils:3.5.0'
    //选择本地文件框架
    compile 'com.github.LuckSiege.PictureSelector:picture_library:v2.1.1'
    //加载图片
    compile 'com.squareup.picasso:picasso:2.5.2'
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    testCompile 'junit:junit:4.12'
}

主要是用到了：

//网络请求相关框架
 compile ‘org.xutils:xutils:3.5.0’
 //选择本地文件框架
 compile ‘com.github.LuckSiege.PictureSelector:picture_library:v2.1.1’

网络框架有很多,此处就选用了xutils了。既然要从手机里选择图片，由于安卓系统各种开源,各大厂商定制原因,自己以前也试着做过从相册选择照片，但是对于机型兼容不好,这个框架主要就是用来从手机里选择照片，当然，也可以选择其他文件,感兴趣可以去他的GitHub了解下。

权限：

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.CAMERA" />

xutils需要在AndroidManifest.xml：

初始化下xutils：

public class MyApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        x.Ext.init(this);
    }
}

接下来还有两个布局文件文件和一个实体类,一个自定义适配器类,一个主类直接贴代码了：
Commodity.java:

/**
 * Created by Administrator on 2019/2/17.
 * 商品对应实体类
 */
public class Commodity {
    //唯一标,没有业务含义
    private Long id;
    //图片地址或者路径,1-6
    private List<String> imageAddress=new ArrayList<>();
    //商品标题
    private String title;
    //描述内容
    private String content;
    //商品价格
    private Double price;
    //商品分类
    private Integer classify;
    //联系手机
    private String mobile;
    //QQ or  weChat
    private String QQ;
    //发布地址
    private String address;
    public Long getId() {
        return id;
    }
    public void setId(Long id) {
        this.id = id;
    }
    public List<String> getImageAddress() {
        return imageAddress;
    }

    public void setImageAddress(List<String> imageAddress) {
        this.imageAddress = imageAddress;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getContent() {
        return content;
    }

    public void setContent(String content) {
        this.content = content;
    }

    public Double getPrice() {
        return price;
    }

    public void setPrice(Double price) {
        this.price = price;
    }

    public Integer getClassify() {
        return classify;
    }

    public void setClassify(Integer classify) {
        this.classify = classify;
    }

    public String getMobile() {
        return mobile;
    }

    public void setMobile(String mobile) {
        this.mobile = mobile;
    }

    public String getQQ() {
        return QQ;
    }

    public void setQQ(String QQ) {
        this.QQ = QQ;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    @Override
    public String toString() {
        return "Commodity{" +
                "imageAddress=" + imageAddress +
                ", title='" + title + '\'' +
                ", content='" + content + '\'' +
                ", price=" + price +
                ", classify=" + classify +
                ", mobile='" + mobile + '\'' +
                ", QQ='" + QQ + '\'' +
                ", address='" + address + '\'' +
                '}';
    }
}

CustomAdapter.java:

public class CustomAdapter extends BaseAdapter {
    private List<LocalMedia> mData;
    private LayoutInflater layoutInflater;
    public CustomAdapter(Context context, List<LocalMedia> data) {
        this.layoutInflater = LayoutInflater.from(context);
        this.mData = data;
    }
//适配器中数据源的个数
@Override
public int getCount() {
    return mData.size();
}

@Override
public Object getItem(int position) {
    return mData.get(position);
}

@Override
public long getItemId(int position) {
    return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    //将布局文件转化为View对象
    View view = layoutInflater.inflate(R.layout.listview_layout, null);
    ImageView imageView =view.findViewById(R.id.listView_layout_image);
    //获取相应索引的ItemBean对象
    LocalMedia bean = mData.get(position);
    //设置控件对应属性
    Bitmap bitmap = BitmapFactory.decodeFile(bean.getPath());
    imageView.setImageBitmap(bitmap);
    return view;
}
}

先来看下安卓端的效果：

服务端：

为了简便开发,服务直接就使用了springboot来开发了：

先使用idea创建一个支持web项目的springboot项目,此处就不演示了,此处使用了mybatisplus操作了下数据库,也对一些文字进行了处理,觉得比较烦就可以去掉了。。

maven关联：

<dependency>
        <groupId>commons-fileupload</groupId>
        <artifactId>commons-fileupload</artifactId>
        <version>1.4</version>
    </dependency>
    <dependency>
        <groupId>commons-io</groupId>
        <artifactId>commons-io</artifactId>
        <version>2.6</version>
    </dependency>

这是两个apache文件上传的jar,一定需要。

FileUploadApplication.java:

@SpringBootApplication
@ImportResource(locations = {"classpath:dispatcher.xml"})
public class FileUploadApplication {

    public static void main(String[] args) {
        SpringApplication.run(FileUploadApplication.class, args);
    }
}

FileUploadController.java:

@RestController
public class FileUploadController {
    @Autowired
    private CommodityMapper mapper;
    private Logger logger = LoggerFactory.getLogger(getClass());

    //Commodity不需要加注解
    @RequestMapping(value = "/upload", method = RequestMethod.POST)
    public String upload(@RequestParam(value = "pictures") MultipartFile[] pictures,
                         Commodity commodity) {
        // 判断文件是否为空
        if (pictures.length > 0 && pictures != null) {
            try {
                //判断文件目录是否存在，否则自动生成
                String innerPath = ResourceUtils.getURL("classpath:").getPath();
                String targetPath = innerPath + "static/images/upload/";
                File f = new File(targetPath);
                if (!f.exists()) {
                    f.mkdirs();
                }
                for (int i = 0; i < pictures.length; i++) {
                    MultipartFile file = pictures[i];
                    // 文件保存路径
                    String filePath = targetPath + file.getOriginalFilename();
                    // 转存文件
                    file.transferTo(new File(filePath));
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
//        StringBuilder builder = new StringBuilder();
//        for (int i = 0; i < commodity.getImageAddress().size(); i++) {
//            String randomName= UUID.randomUUID().toString().substring(0,10);
//            String filePath = commodity.getImageAddress().get(i);
//            String fileName = null;
//            int end = filePath.lastIndexOf(".");
//            //最后一张图片,做特殊处理
//            if (i == (commodity.getImageAddress().size() - 1)) {
//                fileName = filePath.substring(end, filePath.length() - 1);
//                //改文件名
//                //当前记录id+随机生成名称
//                builder.append("4"+randomName+fileName);
//                break;
//            }
//            fileName = filePath.substring(end);
//            builder.append("4"+randomName+fileName + "@");
//        }
//        logger.info(builder.toString());
//        commodity.setImagePath(builder.toString());
        return "上传成功";
    }
}
