Im developing a REST API with spring-data-rest and I have services collection that run good under spring-data-rest 2.0.2, but when I update its version to 2.1.4.RELEASE or 2.2.0.RC1 it always fails:
Errors of 2.1.4.RELEASE:

Note: In the first case there isn't any exception in the Eclipse console.
try to put the latest spring-data-commons to your classpath or pom file if you are using maven:
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-commons</artifactId>
<version>1.9.0.RELEASE</version>
</dependency>
Your application might be pointing to an older version. HTH

I'm new to Spring and currently doing exactly as a youtube tutorial.
When I request the api by GET method from PostMan, I got following weird error.

The tutorial uses JndiTemplate.lookup for connection.
Here is it.
#Configuration
#EnableWebMvc
#ComponentScan(basePackages = "springrestful_example")
public class WebConfig {
#Autowired
DataSource dataSource;
#Bean
public NamedParameterJdbcTemplate getNamedParameterJdbcTemplate() {
return new NamedParameterJdbcTemplate(dataSource);
}
#Bean
public DataSource getDataSource() throws NamingException{
JndiTemplate jndiTemplate = new JndiTemplate();
DataSource dataSource = (DataSource) jndiTemplate.lookup("java:comp/env/jdbc/springrestful");
return dataSource;
}
}
In server.xml of tomcat v7.0 , I do the following configuration as the tutorial except the database name.
<Context docBase="D:\zwh\WorkSpaces\JavaEE Workspace\SpringRESTFulExample\target\SpringRESTFulExample-0.0.1-SNAPSHOT\" path="/SpringRESTFulExample" reloadable="true">
<Resource
auth="Container"
driverClassName="com.mysql.jdbc.Driver"
maxActive="5" maxIdle="3"
name="jdbc/springrestful"
passoword=""
type="javax.sql.DataSource"
url="jdbc:mysql://localhost:3306/springresttest"
username="root"/>
Am I missing something? I already researched about that spending three days but I only found unrelated stuffs which is not involved in the tutorial. I tried to change version of spring-jdbc dependency. But didn't work either.
I solved my problem after adding mysql-connector-java dependency to my pom.xml.
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>6.0.6</version>
</dependency>
Try to add this dependencies :
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
I am using the HBASE for the storing the real time data and i need all the real time data between the two dates i,,e. i am fetching the one year data from my HBASE database.
This is the coonection to the HBASE :
Configuration config = HBaseConfiguration.create();
config = HBaseConfiguration.create();
config.set("hbase.zookeeper.quorum", "ApacheHadoopMaster11,ApacheHadoopMaster12,ApacheHadoopSlave11");
config.set("hbase.master", "ApacheHadoopMaster1:60000");
config.set("hbase.zookeeper.property.clientport", "2181");
HBaseAdmin.checkHBaseAvailable(config);
return config;
But while making the connection , i am getting the can not load the hadoop libraries files exception

I’ve try to use event tables in Siddhi engine with connection to Teradata Database through JDBC Teradata driver.
Teradata Database runs as virtual machine on the same machine where WSO2CEP installed.
First of all I’ve put Teradata JDBC driver terajdbc4.jar in the
<WSO2CEP_HOME>/repository/components/lib/
directory, and additional part of driver tdgssconfig.jar put into
<WSO2CEP_HOME>/bin
directory. Then I’ve restarted CEP server and made connection in the “Datasources” with next parameters:
Datasource type: RDBMS
Name: Teradata
Datasource provider: default
Driver: com.teradata.jdbc.TeraDriver
URL: jdbc:teradata://192.168.96.128/LOG=DEBUG
User name: xxxxx
Password: xxxxx
Test connection works fine.
I’ve created a new Execution Plan which join incoming data flow with Teradata db.
#Export('pcrf_out:1.0.0')
define stream pcrf_out (meta_event string, meta_user_id int, value int);
#Import('pcrf_in_filtered:1.0.0')
define stream pcrf_in_filtered (meta_event string, meta_user_id int, value int);
#From(eventtable='rdbms', datasource.name='Teradata', table.name='user_profile')
define table user_profile (user_id int, usual_traf_usg int);
/* JOIN WITH RELATIONAL TABLE */
from pcrf_in_filtered as a join user_profile as b
on a.meta_user_id == b.user_id and b.usual_traf_usg==100
select a.meta_event as meta_event, a.meta_user_id as meta_user_id, a.value as value
<i>insert into pcrf_out;
When I run script validation then I see an error message: Null
Audit.log contains next message:

The same Execution Plan works fine with Mysql connection.
Can anybody help me with it?
Thanks!
Based on above stacktrace similar exception can only occur when there is no any such datasource in the server as specified in the query (See)
Are you sure that you defined a datasource as specified in the query below (Same name, case also identical)..
#From(eventtable='rdbms', datasource.name='Teradata', table.name='user_profile')
Answer for next query--------
To make it work, we have to define db mappings for new database types (By default, it has mappings for h2, mysql, mssql and oracle).. Then please add below entry in db mapping file. You can find a file called rdbms-table-config.xml inside the siddhi-extension-event-table_3.0.5.jar (which is in /repository/components/plugins folder). Please add below property in that file and update the jar file.. Here, you need to add the db meta name as mapping name.. See here..
<mapping db='teradata'>
<elements/>
</mapping>

Following recommendations from Spring Boot JPA - configuring auto reconnect and other posts, I have the following settings in application.properties which should keep the connection alive:
spring.datasource.url: jdbc:mysql://localhost:3306/<database-name>
spring.datasource.username=<username>
spring.datasource.password=<password>
spring.datasource.driverClassName=com.mysql.jdbc.Driver
#
spring.datasource.testWhileIdle=true
spring.datasource.timeBetweenEvictionRunsMillis=3600000
spring.datasource.validationQuery=SELECT 1
spring.datasource.testOnBorrow=true
#
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
The only clue I have is that the crash happens upon a native query (see line #4 in the stack trace above), while other database accesses seem to still work without problems after the app runs overnight. (The query itself works perfectly fine, so I am not publishing it here for brevity.) This tends to suggest that after a native query is run, a connection to the database over which it was executed is retained but not kept alive. Is there a setting to maintain that connection?
Update:
I added the following method to my NativeQuery class (where all native query methods reside):
#Component
public class NativeQuery {
...
private static final long KEEP_ALIVE_MILLIS = 60 * 60 * 1000;
#Scheduled(initialDelay = KEEP_ALIVE_MILLIS, fixedRate = KEEP_ALIVE_MILLIS)
private void connectionKeepAlive() {
boolean success = true;
String msg = "Database connection keep-alive ";
try {
Query query = entityManager.createNativeQuery("SELECT 1");
BigInteger result = (BigInteger)query.getSingleResult();
if (result != null && result.equals(BigInteger.ONE)) {
msg += "succeeded";
}
else {
msg += "failed with result " + (result != null ? result.toString() : "N/A");
success = false;
}
}
catch (Exception e) {
msg += "crashed with exception: " + e.toString();
success = false;
}
if (success) {
if (log.isInfoEnabled())
log.info(msg);
}
else {
if (log.isErrorEnabled())
log.error(msg);
}
}
...
}
This code executes a keep-alive query once per hour. I let it run overnight and when I logged back in and executed a native query, the above exception was no longer reported. So, this fix seems to work.
However, this also implies that all native queries share the same connection. What happens if multiple queries need to be concurrently executed and there is only a single instance of the NativeQuery class, per Spring Boot's general instantiation rules?
A side comment: Notice how query.getSingleResult() returns a BigInteger. Technically, SELECT 1 returns MySQL BIGINT, which is a 64-bit integer, so a Java long would suffice. Inside Hibernate, someone simply translated BIGINT to BigInteger, even though the database dialect is clearly set as MySQL5.
I suggest you to add this config to your application.properties add retest :
spring.datasource.validationQuery=SELECT 1
spring.datasource.testOnBorrow=true
You are using tomcat connection pool. you can maybe try to use a more robust connection pool, like HikariCP
I'm running Grails 2.5.0 using the Spring Security Core plugin. The setup for Spring Security is as vanilla as it gets (no custom filters, providers, userdetails services, etc.).
We have tried to introduce Spring-Session with Redis by mimicking the configuration described here. As such, I have a resources.groovy that looks like this:
redisHttpSessionConfiguration(RedisHttpSessionConfiguration)
redisConnectionFactory(JedisConnectionFactory)
And a WebXmlConfig.groovy that looks something like this:
filterChainProxyDelegator.add = true
filterChainProxyDelegator.targetBeanName = "springSessionRepositoryFilter"
filterChainProxyDelegator.urlPattern = "/*"
When I log in, I can see in Redis that the session is being persisted. However, it appears that the first time the session information is retrieved again, the deserialization of it fails with a ClassNotFoundException:
org.springframework.data.redis.serializer.SerializationException: Cannot deserialize; nested exception is org.springframework.core.serializer.support.SerializationFailedException: Failed to deserialize payload.
