SseEmitter and jackson No suitable converter for class java.lang.String - java

I'm trying to send messages from backend to frontend with SseEmitter from spring 4.2.6 but when I'm send some message or object, I'm getting the error No suitable converter for class java.lang.String because we have the jackson converter on our application, here is the code.
conversor part
private MappingJackson2HttpMessageConverter jacksonConverter() {
ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new Hibernate4Module());
mapper.registerModule(new JodaModule());
mapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
mapper.setDateFormat(new ISO8601DateFormat());
mapper.setVisibility(PropertyAccessor.ALL, Visibility.NONE);
mapper.setVisibility(PropertyAccessor.FIELD, Visibility.ANY);
MappingJackson2HttpMessageConverter jacksonConverter = new MappingJackson2HttpMessageConverter();
mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
jacksonConverter.setObjectMapper(mapper);
return jacksonConverter;
}
#Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
converters.add(jacksonConverter());
super.configureMessageConverters(converters);
}
notification send and link opener
#RestController
#RequestMapping("/api/notification")
public class NotificationEmitterAPI {
public List<SseEmitter> notifiers;
public NotificationEmitterAPI() {
notifiers = new ArrayList<>();
}
#RequestMapping(value = "/getobj")
public SseEmitter objEmitter() throws IOException {
SseEmitter notifier = new SseEmitter();
notifiers.add(notifier);
notifier.onCompletion(() -> notifiers.remove(notifier));
return notifier;
}
#ResponseBody
public void enableEmitter(Object obj) {
notifiers.forEach((SseEmitter emitter) -> {
try {
emitter.send(obj, MediaType.APPLICATION_JSON);
} catch (IOException e) {
emitter.complete();
notifiers.remove(emitter);
e.printStackTrace();
}
});
}
}
and javascript to receive the object
define(['apiLocations'], function (APILocation) {
NotificationEmitterService.$inject = ['GumgaRest', '$http'];
function NotificationEmitterService(GumgaRest, $http) {
var service = new GumgaRest(APILocation.apiLocation + '/api/notification');
service.objEmitter = function() {
var emitter = new EventSource(this.extend('get','/getobj'));
emitter.addEventListener('open', function (e) {
console.log('connected');
});
emitter.addEventListener('message', function (e) {
console.log(e);
}, false);
emitter.addEventListener('error', function (e) {
if (e.readyState == EventSource.CLOSED) {
connected = false;
connect();
}
}, false);
};
return service;
}
return NotificationEmitterService;
});

A little bit late but worth mentioning to try to declare a StringHttpMessageConverter bean and add it to the configuration.
i.e.:
#Bean
public StringHttpMessageConverter stringMessageConverter() {
return new StringHttpMessageConverter();
}

org.springframework.scheduling.annotation #Async throws server error

In the below code
#Async
public void DoAsynOperation(String param) {
restTemplate.exchange("URL", HttpMethod.PUT, entity,Object.class, parameters);
}
when it is called from any function say
#Override
public void callingFunction(String abc) {
DoAsynOperation(abc);
}
I am getting an error like this
[dispatcherServlet] : Servlet.service() for servlet
[dispatcherServlet] in context with path [] threw exception [Request

Any inputs on this?
you have to allow the servlet configuration
for example
public class WebAppInitializer implements WebApplicationInitializer{
#Override
public void onStartup(ServletContext servletContext) throws ServletException {
AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
ContextLoaderListener contextLoaderListener = new ContextLoaderListener(ctx);
servletContext.addListener(contextLoaderListener);
ctx.register(WebConfig.class);
ServletRegistration.Dynamic servlet = servletContext.addServlet("dispatcher", new DispatcherServlet(ctx));
servlet.setLoadOnStartup(1);
servlet.addMapping("/");
servlet.setAsyncSupported(true); // For Allow Async Calls
servlet.setInitParameter("dispatchOptionsRequest", "true");
}
please check you configuration

How to implement connections to Redis Database in Java applications

I am using Redis Database in my Java application (using Spring Boot).
To connect, get, put and delete my json from Redis Cluster I am using Lettuce open source library.
I have a RedisManager class that handlers connection to database and a RedisCache to effectively execute the commands of get, put and del.
RedisManager.java:
import com.lambdaworks.redis.RedisClient;
import com.lambdaworks.redis.RedisURI;
import com.lambdaworks.redis.cluster.ClusterClientOptions;
import com.lambdaworks.redis.cluster.RedisClusterClient;
import com.lambdaworks.redis.cluster.api.StatefulRedisClusterConnection;
import com.lambdaworks.redis.resource.ClientResources;
import com.lambdaworks.redis.resource.DefaultClientResources;
public class RedisManager{
private StatefulRedisClusterConnection<String, String> connection;
private boolean clusterMode
public RedisManager {
this.clusterMode = true;
connect(clusterMode);
}
private void connectToCluster(){
/**
* It simply gets my endpoint as a string
*/
String endpoint = PROPERTIES.getProperty(CLUSTER_ENDPOINT);
ClientResources res = DefaultClientResources.builder()
.ioThreadPoolSize(3)
.computationThreadPoolSize(3)
.build();
clusterClient = RedisClusterClient.create(res, RedisURI.create(endpoint, 6379));
try {
connection = clusterClient.connect();
} catch (Exception e) {
e.printStackTrace();
}
}
}
RedisCache:
import com.lambdaworks.redis.RedisCommandTimeoutException;
import com.lambdaworks.redis.RedisException;
import com.lambdaworks.redis.cluster.api.sync.RedisAdvancedClusterCommands;
public class RedisCache {
private RedisManager redisManager;
public RedisCache() {
this.redisManager = new RedisManager();
}
public String getAttribute(String hash, String key) {
String attribute = null;
try {
if (redisManager.isClusterMode()) {
RedisAdvancedClusterCommands<String, String> syncCommands = redisManager.getConnection().sync();
attribute = syncCommands.hget(hash, key);
} else {
attribute = redisManager.getRedis().hget(hash, key);
}
} catch (NullPointerException e) {
e.printStackTrace();
} finally {
redisManager.getConnection().close();
}
return attribute;
}
How I effectively use these classes:
RedisCache cacheService = new RedisCache();
String fund = null;
String hash = "myHash"
String key = "myKey"
try{
fund = cacheService.getAttribute(hash, key);
} catch (Exception e) {
e.printStackTrace();
}
So, IT WORKS FOR A SMALL NUMBER OF REQUESTS, but, when I stress my API, I receive this error:
2017-06-22 16:16:47.804 WARN 5 --- [nio-8080-exec-5] c.l.r.c.topology.ClusterTopologyRefresh : Cannot connect to RedisURI [host='myHostHere', port=6379]

Spring Cloud REST: 400 while requesting for a JWT token

I'm trying to receive a token object from an AUTH service, but I keep getting a 400 message. With POSTMAN the request with such header + body works fine.
Request code:
...
HttpHeaders httpHeaders = new HttpHeaders();
String auth = "app" + ":" + "thisissecret";
byte[] encodedAuth = Base64.encodeBase64(auth.getBytes(Charset.forName("US-ASCII")));
String authHeader = "Basic " + new String(encodedAuth);
httpHeaders.set("Authorization", authHeader);
Map <String, Object> body = new HashMap <>();
body.put("grant_type", "password");
body.put("scope", "webclient");
body.put("username", authEntity.getUsername());
body.put("password", authEntity.getPassword());
HttpEntity <Map> requestEntity = new HttpEntity <>(body, httpHeaders);
ResponseEntity <Token> loginResponse = restTemplate.exchange(AUTHORIZATION_URL, HttpMethod.POST, requestEntity, Token.class);
The last line is what generates the 400 error.
Here is the Token class:
public class Token {
private String accessToken;
private String tokenType;
private String refreshToken;
private String expiresIn;
private String scope;
private String organisationId;
private String jti;
... getters / setters
And here is how the response json object supposed to look like:
{
"access_token": "*****",
"token_type": "bearer",
"refresh_token": "*****",
"expires_in": 43199,
"scope": "webclient",
"organisationId": "*****",
"jti": "***"
}
And the exception itself:
Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.web.client.HttpClientErrorException: 400 null] with root cause
org.springframework.web.client.HttpClientErrorException: 400 null

Thanks in advance!!
I've solved the problem with this code. Notice the 'MultiValueMap' and 'RestTemplate'.
ClientHttpRequestFactory requestFactory = new
HttpComponentsClientHttpRequestFactory(HttpClients.createDefault());
RestTemplate restTemplate = new RestTemplate(requestFactory);
HttpHeaders httpHeaders = new HttpHeaders();
String auth = "app" + ":" + "thisissecret";
byte[] encodedAuth = Base64.encodeBase64(auth.getBytes(Charset.forName("US-ASCII")));
httpHeaders.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
String authorisation = "Basic " + new String(encodedAuth);
httpHeaders.add("authorization", authorisation);
MultiValueMap <String, String> body = new LinkedMultiValueMap <>();
body.add("scope", "webclient");
body.add("grant_type", "password");
body.add("username", authEntity.getUsername());
body.add("password", authEntity.getPassword());
HttpEntity <MultiValueMap <String, String>> requestEntity = new HttpEntity <>(body, httpHeaders);
ResponseEntity <Token> loginResponse = null;
try {
loginResponse = restTemplate.exchange(AUTHORIZATION_URL, HttpMethod.POST, requestEntity, Token.class);
} catch (HttpClientErrorException ex) {
log.error("Exception: {}", ex.getLocalizedMessage());
response.setStatus(HttpServletResponse.SC_UNAUTHORIZED);
}

Spark: Streaming DataFrame

I wrote a SpringBoot App that can run as Spark Submit job (Never ending job) giving me an endpoint that I can use to get data from SQLContext. I need to stream data as I get from dataframe. I do the following.
Spring Configuration Class
#Configuration
public class SparkConfiguration {
#Bean
public SparkConf sparkConf(){
return new SparkConf().setAppName("TestApp").setMaster("local[*]");
}
#Bean
public JavaSparkContext sparkContext(final SparkConf sparkConf){
return new JavaSparkContext(sparkConf);
}
#Bean
public SQLContext sqlContext(final JavaSparkContext javaSparkContext){
return new SQLContext(javaSparkContext);
}
Rest Controller Class
#RestController
#RequestMapping("/api")
public class TestResource {
#Autowired
private SQLContext sqlContext;
#GetMapping
#ResponseBody
public void test(HttpServletResponse httpServletResponse) throws
IOException {
DataFrame dataFrame =
sqlContext.sql("SELECT * from TABLE_1").toDF();
PrintWriter writer = httpServletResponse.getWriter();
dataFrame.collectAsList().forEach(row -> {
System.out.println(row);
writer.write(String.valueOf(row.get(0)));
writer.flush();
});
}
}
This works fine!!
But this is not really streaming data.
The moment I do, the below.
dataFrame.collectAsList()
The data get accumulated and then I loop.
Let's say the data is huge (in millions), So I tried to get to the "Row" and push data to writer.
Like this:
#GetMapping
#ResponseBody
public void test(HttpServletResponse httpServletResponse) throws IOException {
DataFrame dataFrame = sqlContext.sql("SELECT * from TABLE_1").toDF();
PrintWriter writer = httpServletResponse.getWriter();
dataFrame.javaRDD().map(new Function<Row, Object>() {
#Override
public Object call(Row row) throws Exception {
writer.write(String.valueOf(row.get(0)));
writer.flush();
return null;
}
}).collect();
}
I get Error:

run a simple spring batch from restcontroller

when i run the spring boot application,the batch works perfectly without instantiating the JobLauncher,i think because of the annotation #EnableBatchProcessing,but when i enter a specific url to launch the same batch in restController by instantiating the JobLauncher and guetting the initial job from the context it fails,here is the code :
#RestController
#Import(BatchConfiguration.class)
#EnableBatchProcessing
public class BatchController {
#Autowired
JobLauncher jobLauncher;
#RequestMapping("/run")
public void runBatch() {
System.out.println("starting the job..........");
ApplicationContext context = new AnnotationConfigApplicationContext(
"src/main/resources/batchjob.xml");
Job job = (Job) context.getBean("job");
try {
JobParameters jobParameters = new JobParametersBuilder().addLong(
"time", System.currentTimeMillis()).toJobParameters();
jobLauncher.run(job, jobParameters);
} catch (JobExecutionAlreadyRunningException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (JobRestartException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (JobInstanceAlreadyCompleteException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (JobParametersInvalidException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("finishing the job..........");
}
