I have two databases that are connected to my application and therefore I have two connectors like that:
#Configuration
#EnableTransactionManagement
#EnableJpaRepositories(entityManagerFactoryRef = DMP_SAP_ENTITY_MANAGER_FACTORY_BEAN_NAME)
class SapHanaConnectionConfiguration #Autowired constructor(private val environment: Environment) {
private val driverClassName by lazy { environment.getProperty(DMP_SAP_DRIVER_CLASS_NAME) }
private val jdbcString by lazy { environment.getProperty(DMP_SAP_JDBC_STRING) }
private val username by lazy { environment.getProperty(DMP_SAP_USERNAME) }
private val password by lazy { environment.getProperty(DMP_SAP_PASSWORD) }
#Bean(name = [DMP_SAP_DATA_SOURCE_BEAN_NAME])
fun dataSource(): DataSource = DataSourceBuilder.create()
.driverClassName(driverClassName)
.url(jdbcString)
.username(username)
.password(password)
.build()
#Bean(name = [DMP_SAP_ENTITY_MANAGER_FACTORY_BEAN_NAME])
fun entityManagerFactory(
builder: EntityManagerFactoryBuilder,
#Qualifier(DMP_SAP_DATA_SOURCE_BEAN_NAME) dataSource: DataSource
): LocalContainerEntityManagerFactoryBean = builder
.dataSource(dataSource)
.packages(DMP_SAP_MODEL_PACKAGE)
.persistenceUnit(DMP_SAP_PERSISTENCE_UNIT_NAME)
.build()
#Bean(name = [DMP_SAP_TRANSACTION_MANAGER_BEAN_NAME])
fun transactionManager(#Qualifier(DMP_SAP_ENTITY_MANAGER_FACTORY_BEAN_NAME) entityManagerFactory: EntityManagerFactory): PlatformTransactionManager =
JpaTransactionManager(entityManagerFactory)
}
Problem is that this particular connector should be working only in production environment, because it connects to the database with clients data (which is located int the inner local network and it is not accessible outside of client's network). Right now while developing in my local environment both connectors start and therefore this SapHanaConnection throws exception because it can't establish connection to given DB.

I would like to somehow say that this connector should run only while some profile is active, is it possible?
I'm using Spring Boot with Kotlin.

I am trying to connect to elasticsearch 8 from my springboot 3 project floowing this official doc. But getting connection refused error without much details.
Here is my configuration
#Configuration
#Slf4j
#EnableElasticsearchRepositories(basePackages = "com....elastic")
public class ElasticConfig {
#Bean
public ClientConfiguration clientConfiguration() {
ClientConfiguration clientConfiguration = ClientConfiguration.builder()
.connectedTo("192.168.19.23:9200")
.usingSsl()
.withConnectTimeout(Duration.ofSeconds(5))
.withSocketTimeout(Duration.ofSeconds(3))
.withBasicAuth("elastic", "abc")
.build();
return clientConfiguration;
}
}
I have my SSL certificate in my jdk. The project runs properly but when it tries to save data on elasticsearch, it gets this error

I have double checked my url, port and credentials. How do i solve this problem?
In springboot 3 just creating ClientConfiguration bean is not enough, the configuration class needs to extend the class ElasticsearchConfiguration as well.
#Configuration
#Slf4j
#EnableElasticsearchRepositories(basePackages = "com....elastic")
public class ElasticConfig extends ElasticsearchConfiguration {
#Override
public ClientConfiguration clientConfiguration() {
ClientConfiguration clientConfiguration = ClientConfiguration.builder()
.connectedTo("192.168.19.23:9200")
.usingSsl()
.withConnectTimeout(Duration.ofSeconds(5))
.withSocketTimeout(Duration.ofSeconds(3))
.withBasicAuth("elastic", "abc")
.build();
return clientConfiguration;
}
}
With this configuration ElasticsearchOperations, ElasticsearchClient and RestClient can be autowired as well.
Edit (P.J.Meisch): This is documented as well: https://docs.spring.io/spring-data/elasticsearch/docs/current/reference/html/#elasticsearch.clients.restclient
Currently I am writing Spring boot application to move data from Database in source A to another Database in source B. To do so, I am trying to configure Spring with two datasource and tried to retrive data from source A concurrently and insert to source B. I could retrieve data from source A but the problem is that I could not insert those data to source B. It seems like I didn't configure transactional correctly with EntityManager. Please check my below code and help me figure out this.
Here is my datasource configuration class:
#Configuration
#EnableJpaRepositories(
basePackages = ["com.gdce.xgen.repo.psql"],
entityManagerFactoryRef = "psqlEntityManager",
transactionManagerRef = "psqlTransactional")
#EnableTransactionManagement
#ComponentScan("com.gdce.xgen.repo.psql")
class PsqlDataSource {
#Bean("psqlEntityManager")
fun entityManagerFactory(#Qualifier("psqlDataSource1") dataSource: DataSource): LocalContainerEntityManagerFactoryBean {
val em = LocalContainerEntityManagerFactoryBean()
val vendorAdapter: JpaVendorAdapter = HibernateJpaVendorAdapter()
em.dataSource = dataSource
em.jpaVendorAdapter = vendorAdapter
em.setPackagesToScan("com.gdce.xgen.model.psql")
em.setJpaProperties(hibernateProperties())
return em
}
#Bean("psqlDataSource1")
#ConfigurationProperties("psql.datasource.main.configuration")
fun dataSource(#Qualifier("psqlDataSourceProperties") dataSourceProperties: DataSourceProperties): DataSource {
return dataSourceProperties.initializeDataSourceBuilder().type(HikariDataSource::class.java).build()
}
#Bean("psqlDataSourceProperties")
#ConfigurationProperties("psql.datasource.main")
fun dataSourceProperties(): DataSourceProperties {
return DataSourceProperties()
}
#Bean("psqlTransactional")
fun transactionManager(#Qualifier("psqlEntityManager") entityManager: EntityManager, #Qualifier("psqlDataSource1") dataSource: DataSource): PlatformTransactionManager {
val transactionManager = JpaTransactionManager(entityManager.entityManagerFactory)
transactionManager.dataSource = dataSource
return transactionManager
}
private fun hibernateProperties(): Properties {
val hibernateProperties = Properties()
hibernateProperties.setProperty("hibernate.jdbc.lob.non_contextual_creation", "true")
hibernateProperties.setProperty("hibernate.show_sql", "true")
hibernateProperties.setProperty("hibernate.hbm2ddl.auto", "update")
hibernateProperties.setProperty("hibernate.jdbc.batch_size", "40000")
hibernateProperties.setProperty("hibernate.dialect", "org.hibernate.dialect.PostgreSQLDialect")
hibernateProperties.setProperty("hibernate.connection.pool_size", "20")
hibernateProperties.setProperty("hibernate.order_inserts", "true")
hibernateProperties.setProperty("hibernate.order_updates", "true")
// hibernateProperties.setProperty("hibernate.format_sql", "true")
return hibernateProperties
}
}
Here is the class I use to insert data into destination data source
#Service
class InsertRepo {
#Qualifier("psqlEntityManager")
// #Autowired // also tried this but not working and saw many people use #PersistenceContext and tried it too
#PersistenceContext
private lateinit var entityManager: EntityManager
fun migrate(records: ArrayList<Any>) {
records.parallelStream().forEach { record ->
run {
entityManager.persist(record)
}
}
}
}
Here an error output:

I am getting this exception when trying to implement the redis cache in spring using azure redis cache.
I have configured the cacheConfig as follows,
#Bean
public JedisConnectionFactory redisConnectionFactory() {
JedisConnectionFactory redisConnectionFactory = new JedisConnectionFactory();
redisConnectionFactory.setHostName("hostname");
redisConnectionFactory.setPort(6380);
redisConnectionFactory.setTimeout(100000);
redisConnectionFactory.setPassword("password");
}
#Bean
public RedisTemplate<String, String> redisTemplate(RedisConnectionFactory cf) {
RedisTemplate<String, String> redisTemplate = new RedisTemplate<String, String>();
redisTemplate.setConnectionFactory(cf);
return redisTemplate;
}
#Bean
isCacheManager(redisTemplate);
return cacheManager;
}
I am using azure redis cache. But when I try to insert into the redis cache I get the following exception. I am adding the full exception stack trace.

Also how to set the ssl property when using the JedisConnectionFactory?
Not sure what's the overload for your Factory but you're definitely missing the TLS flag.
See this: https://github.com/xetorthio/jedis/blob/master/src/test/java/redis/clients/jedis/tests/SSLJedisTest.java#L55
6380/TCP is TLS enabled in Azure Redis Cache. You can enable 6379/TCP from the Azure Portal for plain text connections or you can do the right thing.
Check out the official quickstart for Jedis with Azure Redis Cache (note the useSsl flag) - https://learn.microsoft.com/en-us/azure/redis-cache/cache-java-get-started
JedisShardInfo shardInfo = new JedisShardInfo("
<name>.redis.cache.windows.net",
6380,
useSsl);
shardInfo.setPassword("<key>"); /* Use your access key. */
Jedis jedis = new Jedis(shardInfo);
jedis.set("foo", "bar");
String value = jedis.get("foo");
I was also getting this error. Then i follow this link
https://github.com/Azure/azure-redis-cache-samples/blob/master/Java/ClientSamples/src/main/java/jedis/PoolUsage.java
Just to check and connect azure redis instance.
private static void setupPool() {
JedisPool jedisPool = createPool(RedisClientConfig.getInstance());
try (Jedis jedis = jedisPool.getResource()) {
jedis.set("rahul", "Big Data Dev");
String value = jedis.get("rahul");
System.out.println(value);
} catch (JedisConnectionException e) {
System.out.println(String.format("Failed to connect to Redis server: %s", e));
System.out.println(Utils.getSystemMetrics());
System.out.println(Utils.getPoolUsage(jedisPool));
} // implicitly call Jedis.close() to return instance in try clause
}
All the dependent class you will find in above link. Make sure your configuration on RedisClientConfig class should be correct.
Getting Response ->Big Data Dev
I get a spring boot application and trying create a DataSource bean defined by Java configuration:
#Bean(name = "dsBD") #Primary
public DataSource dsBD() {
return DataSourceBuilder.create()
.url("jdbc:mysql://localhost:3306/database?autoReconnect=true")
.username("root")
.password("mysql")
.driverClassName("com.mysql.jdbc.Driver")
.build();
}
#Bean(name = "jdbcBD") #Autowired
public JdbcTemplate jdbcBD(#Qualifier("dsBD") DataSource dsBD) {
return new JdbcTemplate(dsBD);
}
But when starting application, I got the following error:
Caused by: java.lang.IllegalStateException: No supported DataSource type found

In terms to use DataSourceBuilder you need to have one of the following on your classpath:
COMMONS-DBCP
TOMCAT-JDBC
HIKARICP
Otherwise you will get an IllegalStateException for no supported type, as you get now.
I've tried out a good looking example in this topic ( http://shengwangi.blogspot.hu/2015/01/camel-netty-hello-world-simple-example.html ), but it doesn't work for me.
I would like to create an simple workable TCP adapter, which uses an own encoder and decoder. At first I check out above example ( it uses a simple String encoder and decoder ) this way :
CamelContext ccontext = new DefaultCamelContext();
try {
ccontext.addRoutes(new RouteBuilder() {
#Override
public void configure() throws Exception {
from("netty:tcp://localhost:7000?sync=true&keepAlive=true&allowDefaultCodec=false&encoder=#stringEncoder&decoder=#stringDecoder").to("bean:sayHello");
}
});
ccontext.start();
} catch (Exception e) {
e.printStackTrace();
}
And there are two beans, according the above example:
<!-- ChannelBuffer/ByteBuf to String -->
<bean id="stringDecoder" class="org.jboss.netty.handler.codec.string.StringDecoder"/>
<!-- String to ChannelBuffer/ByteBuf -->
<bean id="stringEncoder" class="org.jboss.netty.handler.codec.string.StringEncoder"/>
When I try to start my implementation, i always get the this exception :
org.apache.camel.FailedToCreateRouteException: Failed to create route route1: Route(route1)[[From[netty:tcp://localhost:7000?sync=true&kee... because of Failed to resolve endpoint: netty://tcp://localhost:7000?allowDefaultCodec=false&decoder=%23stringDecoder&encoder=%23stringEncoder&keepAlive=true&sync=true due to: Could not find a suitable setter for property: decoder as there isn't a setter method with same type: java.lang.String nor type conversion possible: No type converter available to convert from type: java.lang.String to the required type: org.jboss.netty.channel.ChannelHandler with value #stringDecoder

Could anybody help me ? Is it my fault, or the above example can't works ? Thank's.
You need to create a spring based camel context, eg
CamelContext ccontext = new DefaultCamelContext();
should be
CamelContext ccontext = new SpringCamelContext(applicationContext);
and then you need to get hold of the spring ApplicationContext so Camel can integrate with Spring and lookup the beans when you define then with <bean>.
An alternative is to setup <camelContext> in the spring xml file which then does all that for you, and then you can still define routes in java code. See Camel docs at: http://camel.apache.org/spring.html
I know it's been 4 years since this question was asked, but maybe still valid to share a solution.
I'm using Netty Camel with Spring boot application and I had to add these two beans to the spring context in order to get sprint encoder and decoder working.
#Bean(name = "stringDecoder")
public StringEncoder getStringEncoder() {
return new StringEncoder();
}
#Bean(name = "stringEncoder")
public StringDecoder getStringDecoder() {
return new StringDecoder();
}
With that everthing is working fine for me.
