项目配置

项目在第三方插件进行二次开发,基于 SpringBoot 注解配置实现。

application.properties 配置:

# 执行类,内部调用,实现前端相关功能
file-manager.command=com.itstyle.cloud.common.elfinder.command
file-manager.thumbnail.width=80
file-manager.volumes[0].Node=
file-manager.volumes[0].source=fileSystem
file-manager.volumes[0].alias=file
# 文件存放目录,可以自定义
file-manager.volumes[0].path=D:/cloudFile
file-manager.volumes[0]._default=true
file-manager.volumes[0].locale=
file-manager.volumes[0].constraint.locked=false
file-manager.volumes[0].constraint.readable=true
file-manager.volumes[0].constraint.writable=true

ElfinderConfiguration 读取配置:

@Component
@ConfigurationProperties(prefix="file-manager") //接收application.properties中的file-manager下面的属性
public class ElfinderConfiguration {

  private Thumbnail thumbnail;

  private String command;

  private List volumes;

  private Long maxUploadSize = -1L;

  //省略部分代码
}

elfinderStorageFactory 初始化 基础Bean:

@Configuration
public class ElFinderConfig {

  @Autowired
  private ElfinderConfiguration elfinderConfiguration;

  @Bean(name = "commandFactory")
  public CommandFactory getCommandFactory() {
    CommandFactory commandFactory = new CommandFactory();
    commandFactory.setClassNamePattern(elfinderConfiguration.getCommand()+".%sCommand");
    return commandFactory;
  }

  @Bean(name = "elfinderStorageFactory")
  public ElfinderStorageFactory getElfinderStorageFactory() {
    DefaultElfinderStorageFactory elfinderStorageFactory = new DefaultElfinderStorageFactory();
    elfinderStorageFactory.setElfinderStorage(getElfinderStorage());
    return elfinderStorageFactory;
  }

  @Bean(name = "elfinderStorage")
  public ElfinderStorage getElfinderStorage() {
    DefaultElfinderStorage defaultElfinderStorage = new DefaultElfinderStorage();

    // creates thumbnail
    DefaultThumbnailWidth defaultThumbnailWidth = new DefaultThumbnailWidth();
    defaultThumbnailWidth.setThumbnailWidth(elfinderConfiguration.getThumbnail().getWidth().intValue());

    // creates volumes, volumeIds, volumeLocale and volumeSecurities
    Character defaultVolumeId = 'A';
    List elfinderConfigurationVolumes = elfinderConfiguration.getVolumes();
    List elfinderVolumes = new ArrayList<>(elfinderConfigurationVolumes.size());
    Map elfinderVolumeIds = new HashMap<>(elfinderConfigurationVolumes.size());
    Map elfinderVolumeLocales = new HashMap<>(elfinderConfigurationVolumes.size());
    List elfinderVolumeSecurities = new ArrayList<>();

    // creates volumes
    for (Node elfinderConfigurationVolume : elfinderConfigurationVolumes) {

      final String alias = elfinderConfigurationVolume.getAlias();
      final String path = elfinderConfigurationVolume.getPath();
      final String source = elfinderConfigurationVolume.getSource();
      final String locale = elfinderConfigurationVolume.getLocale();
      final boolean isLocked = elfinderConfigurationVolume.getConstraint().isLocked();
      final boolean isReadable = elfinderConfigurationVolume.getConstraint().isReadable();
      final boolean isWritable = elfinderConfigurationVolume.getConstraint().isWritable();

      // creates new volume
      Volume volume = VolumeSources.of(source).newInstance(alias, path);

      elfinderVolumes.add(volume);
      elfinderVolumeIds.put(volume, Character.toString(defaultVolumeId));
      elfinderVolumeLocales.put(volume, LocaleUtils.toLocale(locale));

      // creates security constraint
      SecurityConstraint securityConstraint = new SecurityConstraint();
      securityConstraint.setLocked(isLocked);
      securityConstraint.setReadable(isReadable);
      securityConstraint.setWritable(isWritable);

      // creates volume pattern and volume security
      final String volumePattern = Character.toString(defaultVolumeId) + ElFinderConstants.ELFINDER_VOLUME_SERCURITY_REGEX;
      elfinderVolumeSecurities.add(new DefaultVolumeSecurity(volumePattern, securityConstraint));

      // prepare next volumeId character
      defaultVolumeId++;
    }

    defaultElfinderStorage.setThumbnailWidth(defaultThumbnailWidth);
    defaultElfinderStorage.setVolumes(elfinderVolumes);
    defaultElfinderStorage.setVolumeIds(elfinderVolumeIds);
    defaultElfinderStorage.setVolumeLocales(elfinderVolumeLocales);
    defaultElfinderStorage.setVolumeSecurities(elfinderVolumeSecurities);
    return defaultElfinderStorage;
  }
}

CloudDiskController 控制层实现:

@Controller
@RequestMapping("elfinder/connector")
public class CloudDiskController {

  private static final Logger logger = LoggerFactory.getLogger(CloudDiskController.class);

  public static final String OPEN_STREAM = "openStream";
  public static final String GET_PARAMETER = "getParameter";

  @Resource(name = "commandFactory")
  private ElfinderCommandFactory elfinderCommandFactory;

  @Resource(name = "elfinderStorageFactory")
  private ElfinderStorageFactory elfinderStorageFactory;

  @RequestMapping
  public void connector(HttpServletRequest request, final HttpServletResponse response) throws IOException {
    try {
      response.setCharacterEncoding("UTF-8");
      request = processMultipartContent(request);
    } catch (Exception e) {
      throw new IOException(e.getMessage());
    }


    String cmd = request.getParameter(ElFinderConstants.ELFINDER_PARAMETER_COMMAND);
    ElfinderCommand elfinderCommand = elfinderCommandFactory.get(cmd);

    try {
      final HttpServletRequest protectedRequest = request;
      elfinderCommand.execute(new ElfinderContext() {
        @Override
        public ElfinderStorageFactory getVolumeSourceFactory() {
          return elfinderStorageFactory;
        }

        @Override
        public HttpServletRequest getRequest() {
          return protectedRequest;
        }

        @Override
        public HttpServletResponse getResponse() {
          return response;
        }
      });
    } catch (Exception e) {
      logger.error("Unknown error", e);
    }
  }
  //省略部分代码
}

最后,前端页面引入:

    window.onload = function() {       elFinder.prototype.loadCss('/elfinder/jquery-ui-1.12.1.custom/jquery-ui.css');       $('#elfinder').elfinder({         url : '/elfinder/connector',         lang: 'zh_CN',         height : window.innerHeight-20,         commandsOptions: {           edit: {             editors : [               {                 info:{                   name:'编辑',                   urlAsContent: false                 },                 // ACE Editor                 // `mimes` is not set for support everything kind of text file                 load : function(textarea) {                   var self = this,                     dfrd = $.Deferred(),                     cdn = './elfinder/ace/',                     init = function() {                       if (typeof ace === 'undefined') {                         console.log(cdn);                         this.fm.loadScript([                           cdn+'/ace.js',                           cdn+'/ext-modelist.js',                           cdn+'/ext-settings_menu.js',                           cdn+'/ext-language_tools.js'                         ], start);                       } else {                         start();                       }                     },                     start = function() {                       var editor, editorBase, mode,                         ta = $(textarea),                         taBase = ta.parent(),                         dialog = taBase.parent(),                         id = textarea.id + '_ace',                         ext = self.file.name.replace(/^.+\.([^.]+)|(.+)$/, '$1$2').toLowerCase(),                         // MIME/mode map                         mimeMode = {                           'text/x-php'       : 'php',                           'application/x-php'    : 'php',                           'text/html'        : 'html',                           'application/xhtml+xml'  : 'html',                           'text/javascript'     : 'javascript',                           'application/javascript' : 'javascript',                           'text/css'        : 'css',                           'text/x-c'        : 'c_cpp',                           'text/x-csrc'       : 'c_cpp',                           'text/x-chdr'       : 'c_cpp',                           'text/x-c++'       : 'c_cpp',                           'text/x-c++src'      : 'c_cpp',                           'text/x-c++hdr'      : 'c_cpp',                           'text/x-shellscript'   : 'sh',                           'application/x-csh'    : 'sh',                           'text/x-python'      : 'python',                           'text/x-java'       : 'java',                           'text/x-java-source'   : 'java',                           'text/x-ruby'       : 'ruby',                           'text/x-perl'       : 'perl',                           'application/x-perl'   : 'perl',                           'text/x-sql'       : 'sql',                           'text/xml'        : 'xml',                           'application/docbook+xml' : 'xml',                           'application/xml'     : 'xml'                         };                       // set basePath of ace                       ace.config.set('basePath', cdn);                       // set base height                       taBase.height(taBase.height());                       // detect mode                       mode = ace.require('ace/ext/modelist').getModeForPath('/' + self.file.name).name;
