如何使用Java代码将文档添加到Alfresco存储库？ [英] How to add a document to the Alfresco Repository with Java code?
问题描述
编辑：显然我必须制作一个AMP并将其映射到Alfresco.war。但现在我无法访问我编写的代码，所以我想我将不得不使用Webscripts等。有人可以提供一个如何使用Java支持的webscript将文档添加到Alfresco存储库的示例吗？
原始问题：
我在google范围内搜索了一种使用Java代码将文档添加到Alfresco存储库的方法。但我无法找到一种可行的方法。我知道如何将文档添加到存储库：使用NodeService。但问题是我无法获得NodeService的实例。我试图用@Autowired注入它，我尝试使用bean并尝试使用ApplicationContext。没有一种方法有效......
I've searched google-wide for a way to add a document to the Alfresco Repository with Java code. But I was not able to find a way that would work. I know how I can add a document to the Repository: use the NodeService. But the problem is that I cannot get an instance of the NodeService. I've tried to inject it with @Autowired, I've tried using a bean and I've tried using an ApplicationContext. None of the ways worked...
方式＃1：
注入课程：
Way #1:
Injection in a class:
@Autowired
NodeService nodeService
方式＃2：
在service-context.xml中：
Way #2:
In service-context.xml:
<bean id="somerandombeanname" class="management.FileManager" >
<property name="moduleId" value="${project.artifactId}" />
<property name="serviceRegistry" ref="ServiceRegistry" />
<property name="nodeService" ref="NodeService" />
<property name="transactionService" ref="TransactionService" />
<property name="contentService" ref="ContentService" />
</bean>
在课程中，我为所有服务和serviceRegistry添加了一个getter和setter：
In the class I added a getter and setter for all the services and the serviceRegistry:
private NodeService nodeService;
public void setNodeService(NodeService nodeService) {
this.nodeService = nodeService;
}
方式＃3：
Way #3:
appContext = new ClassPathXmlApplicationContext("classpath:alfresco/application-context.xml");
serviceRegistry = (ServiceRegistry) appContext.getBean(ServiceRegistry.SERVICE_REGISTRY);
nodeService = serviceRegistry.getNodeService();
方法＃1和＃2给了我一个NullPointerException，只是声明NodeService为null。方式＃3给出了一英里长的StackTrace因为AlfrescoRuntimeException而无法初始化密钥库：
Ways #1 and #2 gave me a NullPointerException simply stating the NodeService is null. Way #3 gave a mile long StackTrace because of an AlfrescoRuntimeException because it failed to initialize a keystore:

是的，密钥库存在，是的，我已经重新生成了一个新的密钥库。
Yes, the keystore exists and yes I have regenerated a new keystore.
我正在使用Alfresco 5.0.1和我我正在存储库方面工作（不是分享）。
I'm using Alfresco 5.0.1 and I'm working on the Repository side (not Share).
推荐答案
最后！这是将文件添加到存储库的解决方案：
Finally! This is the solution for adding a file to the Repository:
CustomFileUpload.java：
CustomFileUpload.java:
package org.example;
import org.springframework.extensions.webscripts.Cache;
import org.springframework.extensions.webscripts.DeclarativeWebScript;
import org.springframework.extensions.webscripts.Status;
import org.springframework.extensions.webscripts.WebScriptRequest;
import java.io.File;
import java.io.IOException;
import java.io.Serializable;
import java.util.HashMap;
import java.util.Map;
import org.alfresco.error.AlfrescoRuntimeException;
import org.alfresco.model.ContentModel;
import org.alfresco.repo.content.MimetypeMap;
import org.alfresco.service.ServiceRegistry;
import org.alfresco.service.cmr.repository.ContentWriter;
import org.alfresco.service.cmr.repository.NodeRef;
import org.alfresco.service.cmr.repository.StoreRef;
import org.alfresco.service.cmr.search.ResultSet;
import org.alfresco.service.cmr.search.SearchService;
import org.alfresco.service.namespace.NamespaceService;
import org.alfresco.service.namespace.QName;
import org.apache.commons.io.FileUtils;
public class CustomFileUpload extends DeclarativeWebScript {
private final String UPLOAD_FILE_PATH = "{someRandomFile}";
private final String UPLOAD_DESTINATION = "workspace://SpacesStore/{someRandomNodeRef}";
protected ServiceRegistry serviceRegistry;
public ServiceRegistry getServiceRegistry() {
return serviceRegistry;
}
public void setServiceRegistry(ServiceRegistry serviceRegistry) {
this.serviceRegistry = serviceRegistry;
}
protected Map<String, Object> executeImpl(WebScriptRequest req, Status status, Cache cache) {
File file = new File(UPLOAD_FILE_PATH);
// NodeRef parent = getCompanyHome();
NodeRef parent = new NodeRef(UPLOAD_DESTINATION);
String name = "name of file in Repository " + System.currentTimeMillis();
Map<QName, Serializable> props = new HashMap<QName, Serializable>(1);
props.put(ContentModel.PROP_NAME, name);
// use the node service to create a new node
NodeRef node = serviceRegistry.getNodeService().createNode(
parent,
ContentModel.ASSOC_CONTAINS,
QName.createQName(NamespaceService.CONTENT_MODEL_1_0_URI, name),
ContentModel.TYPE_CONTENT, props).getChildRef();
// Use the content service to set the content onto the newly created
// node
ContentWriter writer = serviceRegistry.getContentService().getWriter(node, ContentModel.PROP_CONTENT, true);
writer.setMimetype(MimetypeMap.MIMETYPE_TEXT_PLAIN);
writer.setEncoding("UTF-8");
String text = "";
try {
text = FileUtils.readFileToString(file);
} catch (IOException e) {
e.printStackTrace();
}
writer.putContent(text);
Map<String, Object> model = new HashMap<String, Object>();
if (status.getCode() == Status.STATUS_OK) {
model.put("resultRepoWS", "File \"" + file.getName() + "\" uploaded successfully to the repository. Status: " + status.getCode());
return model;
} else {
model.put("resultRepoWS", "There was an error while uploading document \"" + file.getName() + "\" - Status: " + status.getCode());
return model;
}
}
//If you want to test with CompanyHome first use this method instead of the NodeRef
@SuppressWarnings("unused")
private NodeRef getCompanyHome() {
StoreRef storeRef = new StoreRef(StoreRef.PROTOCOL_WORKSPACE, "SpacesStore");
serviceRegistry.getSearchService();
ResultSet rs = serviceRegistry.getSearchService().query(storeRef, SearchService.LANGUAGE_XPATH, "/app:company_home");
NodeRef parent = null;
try {
if (rs.length() == 0) {
throw new AlfrescoRuntimeException("Didn't find Company Home");
}
parent = rs.getNodeRef(0);
} finally {
rs.close();
}
return parent;
}
}
此java类放在以下文件夹中：
This java class is placed in the following folder:
{tomcat} \webapps \alfresco \ WEB-INF \classes\org\example
{tomcat}\webapps\alfresco\WEB-INF\classes\org\example
其中org \ example与包org.example相同。现在我们有一个类，现在我们需要配置文件，因为我调用它们：
Where org\example is the same as the package org.example. Now we have a class, now we need the configuration files as I call them:
- customfileupload-context。 xml
位于此处
- {tomcat} \ shared \classes \alfresco \extension
您还需要这些：
- customfileupload.post。 desc.xml
- customfileupload.post.json.ftl
哪些位于此处
- {tomcat} \ shared \classes \alfresco \ extension \webscripts\org\example
注意到文件夹？它与前面提到的包一样。
Noticed the folder? It's the same like the package mentioned earlier.
customfileupload-context.xml的内容：
Contents of customfileupload-context.xml:
<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN 2.0//EN'
'http://www.springframework.org/dtd/spring-beans-2.0.dtd'>
<beans>
<bean id="webscript.org.example.customfileupload.post" class="org.example.CustomFileUpload" parent="webscript">
<property name="ServiceRegistry" ref="ServiceRegistry" />
</bean>
</beans>
customfileupload.post.desc.xml的内容：
Contents of customfileupload.post.desc.xml:
<webscript>
<shortname>File Upload</shortname>
<description>Upload files to user home</description>
<url>/upload/fileupload.json</url>
<format default="json"/>
<authentication runas="admin">guest</authentication>
<transaction>required</transaction>
</webscript>
customfileupload.post.json.ftl的内容：
Contents of customfileupload.post.json.ftl:
<#escape x as jsonUtils.encodeJSONString(x)> { "resultRepoWS": "${resultRepoWS}" } </#escape>
就是这样。有了这个，您就可以使用Alfresco 5将文件上传到Alfresco的存储库。
This is it. With this you'll be able to upload a file to the Repository of Alfresco with Alfresco 5.
