java.net.SocketException: Connection reset when sending HTTP request with RestTemplate

I am trying to send a POST request with Spring Rest Template to a certain URL and getting java.net.SocketException: Connection reset.
This is the actual piece of code that is executed:
ResponseEntity<Void> response = restOperations.exchange(eventLoggingHost, HttpMethod.POST, httpEntity, Void.class);
I get the following exception:

What could be the cause of this?
I have read something about closed sockets but I do not operate any of these notions at this level.

It turned out there is a time out for request on the network level set by some of the Big IP services. We had to ask the maintenance engineers to increase the time out to allow for the time our request is processed.
Of course, request duration limits are set for a reason, and refactoring your code to fragment a long-executed request must be concidered rather than just increasing the timeout.

Issue while Authenticating user with Active Directory (using AD domain) using Spring Security from Spring-boot Application

I'm trying to authenticate the users from Active Directory by using
org.springframework.security.ldap.authentication.ad.ActiveDirectoryLdapAuthenticationProvider
CustomLdapAuthenticationProvider.java
#Override
public Authentication authenticate(Authentication authentication) throws AuthenticationException {
ActiveDirectoryLdapAuthenticationProvider activeDirectoryLdapAuthenticationProvider =
new ActiveDirectoryLdapAuthenticationProvider("companyDomain", "ldap://companyDomain:389", "rootDN");
activeDirectoryLdapAuthenticationProvider.setConvertSubErrorCodesToExceptions(true);
activeDirectoryLdapAuthenticationProvider.setUseAuthenticationRequestCredentials(true);
activeDirectoryLdapAuthenticationProvider.setSearchFilter("(userPrincipalName={0})");
activeDirectoryLdapAuthenticationProvider.setUserDetailsContextMapper(customUserDetailsContextMapper);
authentication = activeDirectoryLdapAuthenticationProvider.authenticate(authentication);
return authentication;
}
When I use IP in the url (ldap://x.x.x.x:389), authentication with AD is successful. But when I use domain in ldap url (ldap://companyDomain:389), code throws below exception
2018-05-16 22:57:23.711 ERROR 11552 --- [nio-8080-exec-9] o.a.c.c.C.[.[.[.[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [/api] threw exception

My requirement is to connect to AD and authenticate user by using AD domain.
Java/Spring allows me to do the same using IP but not domain.

It could be DNS issue, can you run dig command and check whether it resolves the ipaddress
dig companyDomain

java.lang.ClassCastException (Cannot cast class to same class)

Class UserPrincipal extends the Spring class User. Most of the time this works with no problem. But no we want to put some data from the UserPrincipal to log. So we created custom Converters for the logback to add USer and Session info to the log.
Problem is that the User info is asked from the principal that is gotten from Authentication. It gives error UserPrincipal cannot be cast to UserPrincipal.
I know about the classloader problem that causes this. Here the problem is probably that the converter classes created for the logback are not in spring context. Is there a way to get this working or is there any other way to get the User and Session data to log ?
EDIT UserConverter
public class UserConverter extends ClassicConverter{
#Override
public String convert(ILoggingEvent iLoggingEvent){
try {
Long userId = SecurityUtils.getClientId();
if (userId != null) {
return Long.toString(userId);
}
}catch(Throwable ex){
ex.printStackTrace();
return "NO_USER";
}
return "NO_USER";
}
}
The part where the error comes. This is in SecurityUtils
SecurityContext securityContext = SecurityContextHolder.getContext();
Authentication authentication = securityContext.getAuthentication();
UserPrincipal userPrincipal = (UserPrincipal) authentication.getPrincipal();

If this is really an issue with different ClassLoaders and you only want the Id or another "known" field from this instance you have two options:
Read the Field using Reflection (e.g. authentication.getPrincipal().getDeclaredField("userId").get(authentication.getPrincipal()) or
Make a "Serialization Roundtrip" (e.g. (UserPrincipal) org.apache.commons.lang3.SerializationUtils.roundtrip(authentication.getPrincipal())) if the Object implements Serializable

The problem is that the method authentication.getPrincipal() cannot be converted to a UserPrincipal object.
You should look what's the instance of authentication.getPrincipal().
EDIT: now that I see your stacktrace, it must be a ClassLoader related issue.

You can use BeanUtils.copyProperties instead of casting
Authentication authentication = securityContext.getAuthentication();
UserPrincipal userPrincipal = new UserPrincipal();
BeanUtils.copyProperties(userPrincipal, securityContext.getAuthentication());
https://commons.apache.org/proper/commons-beanutils/apidocs/org/apache/commons/beanutils/BeanUtils.html#copyProperties-java.lang.Object-java.lang.Object-

String.valueOf(longvalue)
Try this

Since this approach didnt work. We ended up using MDC to put the keys and AOP #Pointcut and #Around the inject the data into the logger.

Why am I getting a NonUniqueResultException from my Spring Repository?

I'm currently working on a web app that will rate neighbourhoods on a number of different criteria, one of which being statistics from the local Garda station (police station in Irish). I'm passing a latitude and longitude value from the client side into a controller in Spring and I want to run the following Haversine Formula in an SQL query so I can find the nearest police station and return the relevant statistics. (There are 41 stations in the database and the entities have a name, latitude and longitude variable).
I'm getting the following error:
javax.persistence.NonUniqueResultException: result returns more than one elements
In my controller class, I'm getting a longitude and latitude value from the client side and storing them into a latitude and longitude variable with the following snippet. (As previously stated I find the nearest police station and return the relevant statistics but for now, I'm attempting to print the closest station's name in the console to ensure the method is working correctly before moving on)
#RequestMapping(value = "/results", method = RequestMethod.POST)
#ResponseBody
public String Submit(#Valid GardaStation gardaStation, #RequestParam("latitude") Double latitude,#RequestParam("longitude") Double longitude) {
// Attempt at passing the lat and long input by user from the client side to the repository and returning the single top (or nearest) result
gardaStation = gardaStationRepository.findTopByGardaStation_LatitudeAndGardaStation_Longitude(latitude, longitude);
System.out.println(gardaStation.getGardaStation_name());
return "/";
}
In my GardaStationRepository, I'm running the following code which will query the database for the closest result based on the haversine formula. I added "top" to "findTopByGardaStation_LatitudeAndGardaStation_Longitude" repository function as I cannot use SQL's "LIMIT 1" to return a single row. [Using top instead of LIMIT] (https://docs.spring.io/spring-data/jpa/docs/current/reference/html/#repositories.limit-query-result)!
static final String HAVERSINE_PART = "(6371 * acos(cos(radians(:latitude)) * cos(radians(m.gardaStation_latitude)) * cos(radians(m.gardaStation_longitude) - radians(:longitude)) + sin(radians(:latitude)) * sin(radians(m.gardaStation_latitude))))";
#Query("SELECT m FROM GardaStation m ORDER BY "+HAVERSINE_PART+" DESC")
public GardaStation findTopByGardaStation_LatitudeAndGardaStation_Longitude(#Param("latitude") final double latitude, #Param("longitude") final double longitude);
As I'm trying to pass a single GardaStation object in both the controller, repository, as well as using "top" in the repository function name why am I still getting the "result returns more than one elements" error?

If you use #Query annotation, then spring data method name logic is not work. You can include SQL logging, and see what SQL query invoked. I think you need added next query to your annotation if you use MySQL database:
#Query("SELECT m FROM GardaStation m ORDER BY" + HAVERSINE_PART + "DESC LIMIT 1")

Failed to validate a newly established connection. happened on as400

I use the spring-boot first time.A sample page was working on db2 of windows.
I want use the db2 for as400,but a connection error happened when query.

Same error when using spring.datasource.validationQuery=select 1.
And the sql [select 1 from sysibm/sysdummy1] were successful excuted on pcom's strsql.
application.properties for db2 on windows.

spring.datasource.validationQuery=select 1

Since you are on tomcat, can you try with spring.datasource.tomcat.validationQuery
instead of spring.datasource.validationQuery ?
see https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-1.4-Release-Notes#datasource-binding

spring.datasource.validationQuery=select 1
->
spring.datasource.tomcat.validationQuery=select 1 from sysibm/sysdummy1
Use "tomcat.validationQuery" instead of "validationQuery" fixed it. Thanks for every one.
