GET http://myserverip:8081/myapp/api/v1/campaigns 500 (Internal Server Error)

I am having some strange issue, my spring boot app works just fine on localhost, but, when deploying it on the server, sometimes it loads data just fine, but I get 500 error occasionally, it's on the pages where I display data from mysql using angularJS.
Has anyone experienced a similar issue?
Below is my application.properties file:
spring.jpa.hibernate.ddl-auto=update
# Replace with your connection string
spring.datasource.url=jdbc:mysql://localhost:3306/myapp
spring.datasource.connectionProperties=useUnicode=true;characterEncoding=utf-8;
# Replace with your credentials
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.test-while-idle=true
spring.datasource.test-on-borrow=true
spring.datasource.connection-test-query=SELECT 1
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.database-platform=org.hibernate.dialect.MySQL5InnoDBDialect
And here is the log ( sry because it's long ):

I believe I have resolved the issue by adding new dependencies to my pom.xml file, and editing application.properties file as shown below:
spring.jpa.hibernate.ddl-auto=update
# Replace with your connection string
spring.datasource.url=jdbc:mysql://localhost:3306/myapp
spring.datasource.connectionProperties=useUnicode=true;characterEncoding=utf-8;

spring.datasource.username=root
spring.datasource.password=root
#spring.datasource.test-while-idle=true
# Keep the connection alive if idle for a long time (needed in production)
spring.datasource.testWhileIdle = true
spring.datasource.validationQuery = SELECT 1
spring.datasource.test-on-borrow=true
spring.datasource.connection-test-query=SELECT 1
spring.datasource.tomcat.validation-interval=0
# Number of ms to wait before throwing an exception if no connection is available.
spring.datasource.tomcat.max-wait=10000

spring.datasource.driver-class-name=com.mysql.jdbc.Driver
#spring.jpa.database-platform=org.hibernate.dialect.MySQL5InnoDBDialect
# The SQL dialect makes Hibernate generate better SQL for the chosen database
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

ElasticSearch PORT 9300 connection refused

I've deployed Elasticsearch 5.1.2 in docker version 1.12.6.
When i run telnet to 9200 and 9300 port of the server using localhost then it says the connection is successful.
But when i run telnet to 9300 port of the server using the server address it says connection refused.
I've also tried to execute some search request from my JAVA application to Elasticsearch using the server HOST name and the PORT 9300 then I get the following error:

My configuration in elasticsearch.yml is:-
http.host: 0.0.0.0
cluster.name: goglides_cluster
node.name: dev-node
http.cors.enabled: true
http.cors.allow-origin: "*"
Docker run Command Use:
docker run -d -p 9200:9200 -p 0.0.0.0:9300:9300 -v /data/config:/usr/share/elasticsearch/config --name=elasticsearch elasticsearch:5.1.2
And tried this command for JAVA application
docker run -d --name=goglides-search -p 8060:8080 --link=elasticsearch <java-app-image>
I can curl elasticsearch:9200 from goglides-search container
Please let me know what I'm missing.

docker run -d -p 9200:9200 -p 9300:9300 ....
IMO, you should try without 0.0.0.0, only ports in command line.

Spring Boot JDBCConnectionException rarely

I am sometimes having following JDBC error while calling
ServProviderRepository->findServices
After attemting 10-15 times, service starts to response again.
I think there should be reqquired to tune the JDBC connection pool management for springboot, What do you advice to solve this problem?
Spring definition:
#Bean(destroyMethod = "close")
public DataSource getDataSource() throws Exception {
com.mchange.v2.c3p0.ComboPooledDataSource ds = new com.mchange.v2.c3p0.ComboPooledDataSource();
ds.setUser(this.dbPropertyBean.getDsUsername());
ds.setPassword(this.dbPropertyBean.getDsPassword());
ds.setJdbcUrl(this.dbPropertyBean.getDsJdbcUrl());
ds.setDriverClass(this.dbPropertyBean.getDsDriverClass());
ds.setMaxPoolSize(this.dbPropertyBean.getDsMaxPoolSize());
ds.setMinPoolSize(this.dbPropertyBean.getDsMinPoolSize());
ds.setInitialPoolSize(this.dbPropertyBean.getDsInitPoolSize());
ds.setAcquireIncrement(this.dbPropertyBean.getDsAcquireInc());
ds.setAcquireRetryAttempts(this.dbPropertyBean.getDsAcquireRetryAtt());
return ds;
}
Using : Spring Boot 1.3.3.RELEASE
Here is datasource configuration:
ds.maxPoolSize = 5
ds.minPoolSize = 1
ds.initPoolSize = 1
ds.acquireInc = 1
ds.acquireRetryAtt = -1

Spring + hibernate - use Oracle UCP connection pool

I have a basic spring boot application and I have successfully connected to an Oracle DB. However I'd like to use the Oracle's UCP connection pool instead of the default. I have the following application.properties config:
spring.datasource.driver-class-name=oracle.jdbc.OracleDriver
spring.datasource.type=oracle.ucp.jdbc.PoolDataSourceImpl
spring.jpa.database-platform=org.hibernate.dialect.OracleDialect
However, when querying the db I get:
oracle.ucp.UniversalConnectionPoolException: Error during pool creation in Universal Connection Pool Manager MBean: oracle.ucp.UniversalConnectionPoolException: Error during pool creation in Universal Connection Pool Manager: java.sql.SQLException: Invalid Universal Connection Pool configuration: java.sql.SQLException: Unable to create factory class instance with provided factory class name: java.lang.ClassNotFoundException:

I have the ucp.jar (as downloaded from Oracle's site) in my classpath.

At the end of the day I gave up on using strictly configuration properties and followed the steps listed here: http://ebcidicrants.blogspot.bg/2015/07/using-oracle-ucp-as-default-datasource.html. These did the trick with a minor change regarding the reading of the configuration
#ConfigurationProperties(prefix="datasource.ucp")
#Component
public class UCPDataSourceProperties { ... }
And
#Bean
#Primary
#Autowired
public DataSource ucpDataSource(UCPDataSourceProperties properties) throws SQLException { ... }

Here is a working example (without the need for ConfigurationProperties)...
Below is an example snippet of configuration properties in application.properties file:
spring.datasource.url=jdbc:oracle:thin:#someServiceName_tp?TNS_ADMIN=/someLocation/Wallet_someWallet
spring.datasource.username=someUser
spring.datasource.password=somePassword
spring.datasource.driver-class-name=oracle.jdbc.OracleDriver
spring.datasource.type=oracle.ucp.jdbc.PoolDataSource
spring.datasource.oracleucp.connection-factory-class-name=oracle.jdbc.replay.OracleDataSourceImpl
spring.datasource.oracleucp.database-name=oracleADBForGraphQL
spring.datasource.oracleucp.data-source-name=oracleADBForGraphQLDataSource
spring.datasource.oracleucp.description="Oracle ADB Used For GraphQL"
and here are the Oracle dependencies...

<groupId>com.oracle.database.jdbc</groupId>
<artifactId>ojdbc11</artifactId>
<version>21.1.0.0</version>

Hibernate and MySQL broken pipe

I thought I had solved this problem, but in production environment it happens too often and I have to fix it.
To fix this problem I added a scheduled query (I read about 8h timing):
//This task is executing every 3h
#Scheduled(fixedDelay = 10800000)
public void smartQuery(){
try {
LOG.info("SCHEDULED ACTIVITY TO DELETE OLD NOTIFICATIONS");
notificationManagementServices.deleteOldNotifications();
} catch (QueryException e) {
ErrorResponse errorResponse= ErrorResponseBuilder.buildErrorResponse(e);
LOG.error("Threw exception in WakeUpDatabase::smartQuery :" + errorResponse.getStacktrace());
}
}
but the problem persists. In my log file I can see that the scheduled activity works fine, but the connection with SQL is closed anyway

Caused by: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: The last packet successfully received from the server was 320,797,300 milliseconds ago. The last packet sent successfully to the server was 320,797,300 milliseconds ago. is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem.

How is it possible? How can I fix it? Thanks

please add ?autoReconnect=true at the end of your jdbc url.
it should look like this
hibernate.connection.url=jdbc:mysql://myhost:3306/mydb?autoReconnect=true
if you want to increase the timeout, please see here
