如何使用 Java 代码将文档添加到 Alfresco 存储库？

Question

编辑：显然我必须制作一个 AMP 并将其映射到 Alfresco.war。但是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 之类的。有人可以提供一个示例，说明如何使用 Java 支持的 webscript 将文档添加到 Alfresco 存储库？

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。但是我找不到可行的方法。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。我尝试使用@Autowired 注入它，我尝试使用bean，我尝试使用ApplicationContext。没有一种方法奏效...

方式#1：
类中的注入：

@Autowired
NodeService nodeService

---

方式#2：
在 service-context.xml 中：

<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：

private NodeService nodeService;

public void setNodeService(NodeService nodeService) {
        this.nodeService = nodeService;
}

---

方式#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 ，只是说明 NodeService 为空。由于 AlfrescoRuntimeException 未能初始化密钥库，方式 #3 给出了一英里长的 StackTrace：

是的，密钥库存在，是的，我已经重新生成了一个新的密钥库。

我使用的是 Alfresco 5.0.1，并且我在 Repository 方面工作（不是 Share）。

Answer 1

@Autowired
NodeService nodeService

不能在户外工作

您需要使用正确的 setter 方法注入它。 您的 bean 应该如下所示。

<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>

您的 java 类应包含以下用于注入 nodeService。

private NodeService nodeService;

public void setNodeService(NodeService nodeService) {
        this.nodeService = nodeService;
}

Answer 2

幸运的是，我有通过 JAVA 支持的 webscript 上传文件的代码。希望这对您也有帮助。要创建 java 支持的 webscript，请参阅this

创建一个名为CustomFileUpload.java的类并放入以下内容

package com.upload;

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.InputStream;
import java.net.URL;
import java.net.URLConnection;
import java.util.HashMap;
import java.util.Map;

import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.methods.PostMethod;
import org.apache.commons.httpclient.methods.multipart.FilePart;
import org.apache.commons.httpclient.methods.multipart.MultipartRequestEntity;
import org.apache.commons.httpclient.methods.multipart.Part;
import org.apache.commons.httpclient.methods.multipart.StringPart;
import org.apache.commons.io.IOUtils;
import org.json.JSONException;
import org.json.JSONObject;

public class CustomFileUpload extends DeclarativeWebScript {

    private final String UPLOAD_FILE_PATH = "C:\\Users\\Test\\Desktop\\test.txt";
    private int statusCode;

    protected Map<String, Object> executeImpl(WebScriptRequest arg0, Status status, Cache cache) {
        Map<String, Object> model = new HashMap<String, Object>();
        try {
            String URL = "http://localhost:8080/alfresco/service/upload/fileupload?alf_ticket=" +getAlfticket();
            File file = new File(UPLOAD_FILE_PATH);
            String filetype = "text/plain";
            String filename = file.getName();
            HttpClient client = new HttpClient();
            PostMethod post = new PostMethod(URL);

            Part[] parts = {

                    new FilePart("filedata", filename, file, filetype, null),
                    new StringPart("filename", filename),
                    new StringPart("description", "This is test description"),
                    new StringPart("destination", "workspace://SpacesStore/bb424b1d-0418-4954-8591-b8c807264df0")
            };

            post.setRequestEntity(new MultipartRequestEntity(parts, post.getParams()));
            statusCode = client.executeMethod(post);
            System.out.println(post.getResponseBodyAsString());
            post.releaseConnection();
        } catch (Exception e) {
            e.printStackTrace();
        }
        if (statusCode == 200) {
            model.put("result", "File uploaded successfully.");
            return model;
        } else {
            model.put("result", "There was an error while uploading document.");
            return model;
        }
    }

    private static String getAlfticket() throws IOException, JSONException {
        URL url = new URL("http://localhost:8080/alfresco/service/api/login?u=admin&pw=admin&format=json");
        URLConnection con = url.openConnection();
        InputStream in = con.getInputStream();
        String encoding = con.getContentEncoding();
        encoding = encoding == null ? "UTF-8" : encoding;
        String json = IOUtils.toString(in, encoding);
        JSONObject getData = new JSONObject(json);

        return getData.getJSONObject("data").get("ticket").toString();
    }
}

注意：您可以在目的地中放置您要上传的文件夹的nodeRef。

比在上下文文件名中创建bean，随便你说mycustom-context.xml，然后把它放在ALFRESCO_HOME\tomcat\shared\classes\alfresco\extension和内容中

<bean id="webscript.com.upload.customupload.post" class="com.upload.CustomFileUpload" parent="webscript">
</bean>

最后通过创建customupload.post.desc.xml 在露天注册这个网络脚本。并放

<webscript>
   <shortname>File Upload</shortname>
   <description>Upload files to user home</description>
   <url>/upload/fileupload?alf_ticket={ticket}</url>
   <format default="json"/>
   <authentication>user</authentication>
</webscript>

最后创建视图，因为我们声明 JSON 是默认格式，所以我们需要创建 customupload.post.json.ftl

${result}

并将这两个文件放入ALFRESCO_HOME\tomcat\shared\classes\alfresco\extension\templates\webscripts\com\upload

现在重新启动服务器并点击http://localhost:8080/alfresco/service/upload/fileupload，您将看到文件上传到文件夹中（无论您提供什么）。对于Reference

终于！这是将文件添加到存储库的解决方案：

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;
    }
}

这个java类放在以下文件夹中：

{tomcat}\webapps\alfresco\WEB-INF\classes\org\example

其中 org\example 与包 org.example 相同。现在我们有了一个类，现在我们需要我所说的配置文件：

• 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

位于此处

• {tomcat}\shared\classes\alfresco\extension\webscripts\org\example

注意到文件夹了吗？和前面提到的包是一样的。

customfileupload-context.xml 的内容：

<?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：

<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：

<#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。
