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<Node> 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<Node> elfinderConfigurationVolumes = elfinderConfiguration.getVolumes();
List<Volume> elfinderVolumes = new ArrayList<>(elfinderConfigurationVolumes.size());
Map<Volume, String> elfinderVolumeIds = new HashMap<>(elfinderConfigurationVolumes.size());
Map<Volume, Locale> elfinderVolumeLocales = new HashMap<>(elfinderConfigurationVolumes.size());
List<VolumeSecurity> 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：
<div id="elfinder"></div>
<script type="text/javascript" charset="utf-8">
window.onload = function() {
elFinder.prototype.loadCss('/elfinder/jquery-ui-1.12.1.custom/jquery-ui.css');
