我在露天社区4.0工作，我使用了这个jar alfresco-web-service-client-4.0.d.jar
使用此代码我可以在alfresco中保存我的test.pdf文件：
File file = new File("C:/test.pdf");
saveAttachement(file,"test.pdf", "/app:company_home/cm:MyFolder",
"admin", "admin")
public String saveAttachement(File file, String name, String folderName, String userName, String pwd)
throws Exception {
byte[] contentByte = IOUtils.toByteArray(new FileInputStream(file));
// Start the session
AuthenticationUtils.startSession(userName, pwd);
try {
// Create a reference to the parent where we want to create content
Store storeRef = new Store(Constants.WORKSPACE_STORE, "SpacesStore");
ParentReference companyHomeParent = new ParentReference(storeRef, null, folderName, Constants.ASSOC_CONTAINS, null);
// Assign name
companyHomeParent.setChildName("cm:" + name);
// Construct CML statement to create content node
// Note: Assign "1" as a local id, so we can refer to it in subsequent
// CML statements within the same CML block
NamedValue[] contentProps = new NamedValue[1];
contentProps[0] = Utils.createNamedValue(Constants.PROP_NAME, name);
CMLCreate create = new CMLCreate("1", companyHomeParent, null, null, null, Constants.TYPE_CONTENT, contentProps);
// Construct CML statement to add titled aspect
NamedValue[] titledProps = new NamedValue[2];
titledProps[0] = Utils.createNamedValue(Constants.PROP_TITLE, name);
titledProps[1] = Utils.createNamedValue(Constants.PROP_DESCRIPTION, name);
CMLAddAspect addAspect = new CMLAddAspect(Constants.ASPECT_TITLED, titledProps, null, "1");
// Construct CML Block
CML cml = new CML();
cml.setCreate(new CMLCreate[] { create });
cml.setAddAspect(new CMLAddAspect[] { addAspect });
// Issue CML statement via Repository Web Service and retrieve result
// Note: Batching of multiple statements into a single web call
UpdateResult[] result = WebServiceFactory.getRepositoryService().update(cml);
Reference content = result[0].getDestination();
// Write some content
ContentServiceSoapBindingStub contentService = WebServiceFactory.getContentService();
//String text = "The quick brown fox jumps over the lazy dog";
ContentFormat contentFormat = new ContentFormat("text/plain", "UTF-8");
Content contentRef = contentService.write(content, Constants.PROP_CONTENT, contentByte, contentFormat);
System.out.println("Document are created successfully. UID:= " + content.getUuid());
return content.getUuid();
} catch (Throwable e) {
System.out.println(e.toString());
} finally {
// End the session
AuthenticationUtils.endSession();
//System.exit(0);
}
return null;
}
在alfresco中保存此文件后，我有这个ID d7633eff-8595-4d6c-8c18-a29a656607ba
稍后将用于下载此文件
这是下载代码：
ContentResult contentResult = getContentsById("d7633eff-8595-4d6c-8c18-a29a656607ba", "admin", "admin");
public ContentResult getContentsById(String contentId, String userName, String pwd)
throws Exception {
ContentResult contentResult = new ContentResult();
// Start the session
AuthenticationUtils.startSession(userName, pwd);
try {
Store storeRef = new Store(Constants.WORKSPACE_STORE, "SpacesStore");
ContentServiceSoapBindingStub contentService = WebServiceFactory.getContentService();
Reference contentReference = new Reference(storeRef, contentId, null);
Content[] readResult = null;
try {
readResult = contentService.read(new Predicate(new Reference[] { contentReference }, storeRef, null), Constants.PROP_CONTENT);
} catch (ContentFault e) {
e.printStackTrace();
} catch (RemoteException e) {
e.printStackTrace();
}
if ((readResult != null) && (readResult[0] != null)) {
Content content = readResult[0];
ContentFormat cnf = content.getFormat();
Reference ref = content.getNode();
String[] splitedUrl = content.getUrl().split("/");
String name = splitedUrl[splitedUrl.length - 1];
InputStream is = ContentUtils.getContentAsInputStream(content);
byte[] contentByte = ConvertUtil.convertInputStreamToByte(is);
contentResult.setName(name);
contentResult.setMimetype(cnf.getMimetype());
contentResult.setId(ref.getUuid());
contentResult.setUrl(content.getUrl());
contentResult.setPath(ref.getPath());
contentResult.setContentByte(contentByte);
System.out.println(" document has been retrieved");
}
} catch (Exception e) {
System.out.println(e.toString());
} finally {
// End the session
AuthenticationUtils.endSession();
// System.exit(0);
}
return contentResult;
}
目前我更改 test.pdf 文件内容而不更改文件名 我把它放在光盘的另一个位置。
这是新文件位置。
C：/version/test.pdf
所以在磁盘中我有两个同名但内容不同的文件。
我的目标是在露天保存新文件，但使用版本控制。
在我看来，我必须使用在户外保存的旧ID： d7633eff-8595-4d6c-8c18-a29a656607ba
所以我应该开发一个方法，将新文件和旧id
作为参数 像这样 File file = new File("C:/version/test.pdf");
saveWithVersionAttachement(file,"d7633eff-8595-4d6c-8c18-a29a656607ba","test.pdf", "/app:company_home/cm:MyFolder",
"admin", "admin",)
public String saveWithVersionAttachement(File file,String oldId, String name, String folderName, String userName, String pwd)
throws Exception {
.............
.............
在我看来，这个方法必须将这个新文件保存在alfresco中，如test_2.pdf或test_v2.pdf ..
所以这两个文件保存在露天并具有相同的ID
在下载方法中我想拥有最新版本。
所以我必须更改方法getContentById ("d7633eff-8595-4d6c-8c18-a29a656607ba", "admin", "admin");
要返回最新版本 test_2.pdf或test_v2.pdf ...
我尝试使用 alfresco-OpenCMIS-extension-0.7.jar
与OpenCMIS合作失败我在 Alfresco \ tomcat \ webapps \ alfresco \ WEB-INF \ classes \ alfresco \ model \ contentModel.xml
中添加了这些行<mandatory-aspects>
<aspect>cm:versionable</aspect>
</mandatory-aspects>
我也添加了这一行version.store.enableAutoVersioning=true
是否有人可以帮助我解决我的问题
更新：
我与CMIS合作：

实现这一目标的最快且最简单方式是利用RESTfull API
这也将确保与新版露天的兼容性。
请注意，您需要在表单属性 updatenoderef 中为要更新的文档提供noderef，并且属性 majorversion 是一个布尔标志，用于指定是否为新版本是文档的次要/主要版本。
以下示例代码可以帮助您使用您的用例：
SUMIFS($B:$B;$A:$A;"="Reference)
注1：您需要更换这些tockens＆lt; *＆gt;使用您自己的值/ vars
答案 1 :(得分：0)
如果您已经启用版本控制，则只需使用新二进制文件和新名称更新文档。 Alfresco将负责版本控制。 get方法将检索最后一个版本。
This link describes how to update a document using CMIS
我认为你不需要修改get方法。
