openCMIS 本地绑定 - JcrServiceFactory 与 jackRabbit 实现

Question

嘿，第三种替代方案有问题，因为JcrServiceFactory 中的循环正在搜索以 jcr.* 开头的属性（其他属性不会传递），但紧接着在 RepositoryFactoryImpl (Jackrabbit impl) 中搜索“org.jcr.*”。 apache.jackrabbit.repository.home”在传递的属性集合中......这没有意义。即使 org.apache.jackrabbit.repository.home 存在，它也不会以 PREFIX_JCR_CONFIG 开头，因此它不会放入 jcrConfig 集合中，该集合会转到 RepositoryFactoryImpl .getRepository()

如果 Map是有意义的。 map = null;因为RepositoryFactoryImpl中存在if(parameters == null)条件，但是这并不是

发生在init方法

JcrServiceFactory.java

 private TypeManager typeManager;
    private Map<String, String> jcrConfig;
    private String mountPath;
    private JcrRepository jcrRepository;

    @Override
    public void init(Map<String, String> parameters) {
        typeManager = new TypeManager();
        readConfiguration(parameters);
        jcrRepository = new JcrRepository(acquireJcrRepository(jcrConfig), mountPath, typeManager);
    }

 private void readConfiguration(Map<String, String> parameters) {
        Map<String, String> map = new HashMap<String, String>();
        List<String> keys = new ArrayList<String>(parameters.keySet());
        Collections.sort(keys);

/* the loop is searching for properties starting with jcr.* */

        for (String key : keys) {
            if (key.startsWith(PREFIX_JCR_CONFIG)) {
                String jcrKey = key.substring(PREFIX_JCR_CONFIG.length());
                String jcrValue = replaceSystemProperties(parameters.get(key));
                map.put(jcrKey, jcrValue);
            }

            else if (MOUNT_PATH_CONFIG.equals(key)) {
                mountPath = parameters.get(key);
                log.debug("Configuration: " + MOUNT_PATH_CONFIG + '=' + mountPath);
            }

            else {
                log.warn("Configuration: unrecognized key: " + key);
            }
        }

        jcrConfig = Collections.unmodifiableMap(map);
        log.debug("Configuration: jcr=" + jcrConfig);
    }

中而是这里参数Map为空{}，返回null；因为它正在搜索RepositoryFactoryImpl.REPOSITORY_HOME，即org.apache.jackrabbit.repository.home

RepositoryFactoryImpl.java

/* parameters = jcrConfig */
public Repository getRepository(Map parameters) throws RepositoryException {
        if (parameters == null) {
            return getRepository(null, Collections.emptyMap());
        } else if (parameters.containsKey(REPOSITORY_HOME)) {
            String home = parameters.get(REPOSITORY_HOME).toString();
            return getRepository(home, parameters);
        } else if (parameters.containsKey(JcrUtils.REPOSITORY_URI)) {
            Object parameter = parameters.get(JcrUtils.REPOSITORY_URI);
            try {
                URI uri = new URI(parameter.toString().trim());
                String scheme = uri.getScheme();
                if (("file".equalsIgnoreCase(scheme)
                        || "jcr-jackrabbit".equalsIgnoreCase(scheme))
                        && uri.getAuthority() == null) {
                    File file = new File(uri.getPath());
                    if (file.isFile()) {
                        return null; // Not a (possibly missing) directory
                    } else {
                        return getRepository(file.getPath(), parameters);
                    }
                } else {
                    return null; // not a file: or jcr-jackrabbit: URI
                }
            } catch (URISyntaxException e) {
                return null; // not a valid URI
            }
        } else {
            return null; // unknown or insufficient parameters
        }
    }

Answer 1

答案就在我抱怨的循环中:-)

String jcrKey = key.substring(PREFIX_JCR_CONFIG.length());

它是一个子字符串，所以它会削减jcr。其余的继续...

parameters.put("jcr.org.apache.jackrabbit.repository.home", repositoryHome);

这是一个棘手的问题，需要通过调试来弄清楚所有这些。

Answer 2

您需要使用以下条目在“WEB-INF/classes”处配置“repository.properties”。

jcr.org.apache.jackrabbit.repository.home={user.home}\jcr-repository（您的存储库位置）。

干杯。
