我正在尝试使用twitter4j库为我的java项目发送推文.在我第一次运行时,我收到了关于证书sun.security.validator.ValidatorException和错误的错误sun.security.provider.certpath.SunCertPathBuilderException.然后我添加了twitter证书:

C:\Program Files\Java\jdk1.7.0_45\jre\lib\security>keytool -importcert -trustcacerts -file PathToCert -alias ca_alias -keystore "C:\Program Files\Java\jdk1.7.0_45\jre\lib\security\cacerts"

但没有成功.这是获得twitters的过程:

public static void main(String[] args) throws TwitterException {
    ConfigurationBuilder cb = new ConfigurationBuilder();
    cb.setDebugEnabled(true)
        .setOAuthConsumerKey("myConsumerKey")
        .setOAuthConsumerSecret("myConsumerSecret")
        .setOAuthAccessToken("myAccessToken")
        .setOAuthAccessTokenSecret("myAccessTokenSecret");

    TwitterFactory tf = new TwitterFactory(cb.build());
    Twitter twitter = tf.getInstance();

    try {
        Query query = new Query("iphone");
        QueryResult result;
        result = twitter.search(query);
        System.out.println("Total amount of tweets: " + result.getTweets().size());
        List<Status> tweets = result.getTweets();

        for (Status tweet : tweets) {
            System.out.println("@" + tweet.getUser().getScreenName() + " …

以下代码工作正常:

public static void main(String[] args) {
    String userName = "admin";
    String password = "s3cret";
    Hashtable env = new Hashtable();
    env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
    env.put(Context.PROVIDER_URL, "ldap://192.168.10.45:389/dc=softwaredev,dc=local");
    //env.put(Context.SECURITY_PROTOCOL, "ssl");
    env.put(Context.SECURITY_AUTHENTICATION, "simple");
    env.put(Context.SECURITY_PRINCIPAL, new String("softwaredev" + "\\" + userName));
    env.put(Context.SECURITY_CREDENTIALS, password);

    DirContext ctx = null;
    NamingEnumeration results = null;
    try {
        ctx = new InitialDirContext(env);
        SearchControls controls = new SearchControls();
        controls.setSearchScope(SearchControls.SUBTREE_SCOPE);
        results = ctx.search("", "(objectclass=person)", controls);
        while (results.hasMore()) {
            SearchResult searchResult = (SearchResult) results.next();
            Attributes attributes = searchResult.getAttributes();
            System.out.println(" Person Common Name = " …
