Sending HTML email with Spring Boot and Thymeleaf - java

I am checking out how to send an email using Spring Boot.
Send an e-mail using standard Spring Boot modules and prepare HTML content for a message using Thymeleaf template engine.
This is the dependencies I use

Here my MailClient
#Service
public class MailClient {
private JavaMailSender mailSender;
private MailContentBuilder mailContentBuilder;
#Autowired
public MailClient(JavaMailSender mailSender, MailContentBuilder mailContentBuilder) {
this.mailSender = mailSender;
this.mailContentBuilder = mailContentBuilder;
}
public void prepareAndSend(String recipient, String message) {
MimeMessagePreparator messagePreparator = mimeMessage -> {
MimeMessageHelper messageHelper = new MimeMessageHelper(mimeMessage);
messageHelper.setFrom("amadeu.cabanilles#gmail.com");
messageHelper.setTo("amadeu.cabanilles#gmail.com");
messageHelper.setSubject("Sample mail subject");
String content = mailContentBuilder.build(message);
messageHelper.setText(content, true);
};
try {
mailSender.send(messagePreparator);
} catch (MailException e) {
e.printStackTrace();
}
}
}
This is my Test Class
#RunWith(SpringJUnit4ClassRunner.class)
#SpringApplicationConfiguration(Application.class)
public class MailClientTest {
#Autowired
private MailClient mailClient;
private GreenMail smtpServer;
#Before
public void setUp() throws Exception {
smtpServer = new GreenMail(new ServerSetup(25, null, "smtp"));
smtpServer.start();
}
#Test
public void shouldSendMail() throws Exception {
//given
String recipient = "amadeu.cabanilles#gmail.com";
String message = "Test message content";
//when
mailClient.prepareAndSend(recipient, message);
//then
String content = "<span>" + message + "</span>";
assertReceivedMessageContains(content);
}
private void assertReceivedMessageContains(String expected) throws IOException, MessagingException {
MimeMessage[] receivedMessages = smtpServer.getReceivedMessages();
assertEquals(1, receivedMessages.length);
String content = (String) receivedMessages[0].getContent();
System.out.println(content);
assertTrue(content.contains(expected));
}
#After
public void tearDown() throws Exception {
smtpServer.stop();
}
}
Executing the Test in my computer is OK, I pass the test but I don't receive any email.


You don't receive any email because this integration test uses local testing SMTP server stub - GreenMail. The test doesn't send real emails, only verifies if the mail is prepared and sent correctly if a real SMTP server is available in the production.
In order to send emails from your local environment, you need to setup some SMTP server, but then, automated verification if the mail is actually sent is a completely different story.

The problem of connecting Apache Flink to elasticsearch

I used a piece of code inside the Flink site to connect Apache Flink to Elastic Search. I want to run this piece of code from NetBeans software through maven project.
public class FlinkElasticCon {
public static void main(String[] args) throws Exception {
final int port;
try {
final ParameterTool params = ParameterTool.fromArgs(args);
port = params.getInt("port");
} catch (Exception e) {
System.err.println("No port specified. Please run 'SocketWindowWordCount --port <port>'");
return;
}
// get the execution environment
final StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();
// get input data by connecting to the socket
DataStream<String> text = env.socketTextStream("localhost", port, "\n");
// parse the data, group it, window it, and aggregate the counts
DataStream<WordWithCount> windowCounts = text
.flatMap((String value, Collector<WordWithCount> out) -> {
for (String word : value.split("\\s")) {
out.collect(new WordWithCount(word, 1L));
}
})
.keyBy("word")
.timeWindow(Time.seconds(5))
.reduce(new ReduceFunction<WordWithCount>() {
#Override
public WordWithCount reduce(WordWithCount a, WordWithCount b) {
return new WordWithCount(a.word, a.count + b.count);
}
});
// print the results with a single thread, rather than in parallel
//windowCounts.print().setParallelism(1);
env.execute("Socket Window WordCount");
List<HttpHost> httpHosts = new ArrayList<>();
httpHosts.add(new HttpHost("127.0.0.1", 9200, "http"));
httpHosts.add(new HttpHost("10.2.3.1", 9200, "http"));
ElasticsearchSink.Builder<String> esSinkBuilder = new ElasticsearchSink.Builder<>(
httpHosts,
new ElasticsearchSinkFunction<String>() {
public IndexRequest createIndexRequest(String element) {
Map<String, String> json = new HashMap<>();
json.put("data", element);
return Requests
.indexRequest()
.index("my-index")
.type("my-type")
.source(json);
}
#Override
public void process(String element, RuntimeContext ctx, RequestIndexer indexer) {
indexer.add(createIndexRequest(element));
}
}
);
windowCounts.addSink((SinkFunction<WordWithCount>) esSinkBuilder);
}
public static class WordWithCount {
public String word;
public long count;
public WordWithCount() {}
public WordWithCount(String word, long count) {
this.word = word;
this.count = count;
}
#Override
public String toString() {
return word + " : " + count;
}
}
}
When adding Dependency, it does not identify the elasticsearchsink class. Given that I added different Dependency to it, but the problem is still not resolved. When importing :
import org.apache.flink.streaming.connectors.elasticsearch6.ElasticsearchSink

KafkaTemplate
This is because you are using the TestBinder in your test, not the real Kafka broker and kafka binder.
The message collector is simply fetching it from the channel. If you want to test with a real Kafka broker, see the test-embedded-kafka sample app.
EDIT
I just tested the Ditmars (boot 1.5.x) version of the sample and it works fine...

The issue is because of a bug in atomikos 3.9.3 version in spring-boot-starter-jta-atomikos brings:1.4.2.RELEASE.
Once you update the version to atomikos 4.0.4, the issue resolves.

STOMP in Spring WebSocket Lost Connection before connected

I try to connect with server by STOMP, but I get Lost Connection message with any specific information.
WebSocket config:
#Configuration
#EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {
#Override
public void configureMessageBroker(MessageBrokerRegistry registry) {
registry.enableStompBrokerRelay("/topic", "/queve")
.setClientLogin("quest")
.setClientPasscode("quest");
registry.setApplicationDestinationPrefixes("/app");
}
#Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
registry.addEndpoint("/hello").setAllowedOrigins("*").withSockJS();
}
}
Controller:
#Controller
public class HelloController {
#MessageMapping("/hello")
public void greeting(HelloMessage message){
System.out.println("Wiadomosc: " + message.getName());
}
#SubscribeMapping({"/helloSub"})
public HelloMessage handleSubscription() {
HelloMessage outgoing = new HelloMessage();
System.out.println("SUB");
outgoing.setName("Jas");
return outgoing;
}
}
js script:
var sock = new SockJS("http://localhost:8080/BuyMyTime/hello");
var stomp = Stomp.over(sock);
var payload = JSON.stringify({'name':'Jasiek'});
stomp.connect('quest', 'quest', function(frame){
//stomp.send("/hello", {}, payload);
});
When i send get http://localhost:8080/BuyMyTime/hello i receive: Welcome to SockJS! so Socket is fine but when i try stomp.connect i receive:
Opening Web Socket... stomp.js:134:99
Web Socket Opened... stomp.js:134:99
>>> CONNECT
login:quest
passcode:quest
accept-version:1.1,1.0
heart-beat:10000,10000
"Whoops! Lost connection to http://localhost:8080/BuyMyTime/hello" stomp.js:134:99
Is there any missing config i did not included? How can I get more info about this connection lost? Please for any help.
Update (Aug 28 2016)
I add this dependencies:
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-annotations</artifactId>
<version>2.5.1</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-annotations</artifactId>
<version>2.5.1</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.5.1</version>
</dependency>
and now get:
<<< ERROR
message:Broker not available.
content-length:0
"Whoops! Lost connection to http://localhost:8080/BuyMyTime/greeting"
