I am trying to connect my project with two Redis connection but I got
Consider defining a bean named 'redisTemplate' in your configuration.
I don't know if my code is correct but this is my code config, my spring boot version 2.4.2 :
#Configuration
public class RedisConfiguration {
#Autowired
private EditorialRedisPropertyConfiguration editorialRedisConfiguration;
#Autowired
private ProductRedisPropertyConfiguration productRedisConfiguration;
#Bean(name = "editorialRedisTemplate")
public RedisTemplate<String, ?> editorialRedisTemplate(
#Qualifier(value = "redisEditorialConnectionFactory") RedisConnectionFactory redisConnectionFactory) {
RedisTemplate<String, ?> template = new RedisTemplate<>();
template.setConnectionFactory(redisEditorialConnectionFactory());
return template;
}
#Bean(name = "productRedisTemplate")
public RedisTemplate<String, ?> productRedisTemplate(
#Qualifier(value = "redisProductConnectionFactory") RedisConnectionFactory redisConnectionFactory) {
RedisTemplate<String, ?> template = new RedisTemplate<>();
template.setConnectionFactory(redisConnectionFactory);
return template;
}
#SuppressWarnings("deprecation")
private Jackson2JsonRedisSerializer<Object> initJackson2JsonRedisSerializer() {
. ..
}
#Bean(name = "redisEditorialConnectionFactory")
#Primary
public LettuceConnectionFactory redisEditorialConnectionFactory() {
...
}
#Bean(name = "redisProductConnectionFactory")
#Primary
public LettuceConnectionFactory redisProductConnectionFactory() {
.....
}
}
with application config :
spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.data.redis.RedisReactiveAutoConfiguration
Not quite sure about your application code but this can be fixed by simply creating another bean, given you don't use that you're free to create it from any redis config.
#Bean(name = "productRedisTemplate")
public RedisTemplate<String, ?> redisTemplate(
#Qualifier(value = "redisProductConnectionFactory") RedisConnectionFactory redisConnectionFactory) {
RedisTemplate<String, ?> template = new RedisTemplate<>();
template.setConnectionFactory(redisConnectionFactory);
return template;
}
I have a multi database application. Users can select the database on the login page.
Then the database is routing selected database thanks for AbstractRoutingDataSource from Spring.
I want to use HikariCP, but it needs dataSourceUrl. But my Datasource URL changes dynamically. How can I configure Hikaricp for multiple databases?
File application.properties:
#database1 properties
app.database1.connection.url = url1
app.database1.connection.username = sameusername
app.database1.connection.password = samepassword
#database2 properties
app.database2.connection.url = url2
app.database2.connection.username = sameusername
app.database2.connection.password = samepassword
My Datasource configuration class example:
public class DataSourceConfiguration {
#Autowired(required = false)
private PersistenceUnitManager persistenceUnitManager;
#Bean
#ConfigurationProperties(prefix = "app.database1.connection")
public DataSource database1DataSource() {
return DataSourceBuilder.create().build();
}
#Bean
#ConfigurationProperties(prefix = "app.database2.connection")
public DataSource database2DataSource() {
return DataSourceBuilder.create().build();
}
#Bean
#Primary
public DataSource appDataSource() {
DataSourceRouter router = new DataSourceRouter();
final HashMap<Object, Object> map = new HashMap<>(3);
map.put(DatabaseEnvironment.DATABASE1, database1DataSource());
map.put(DatabaseEnvironment.DATABASE2, database2DataSource());
router.setTargetDataSources(map);
return router;
}
#Bean
#Primary
#ConfigurationProperties("app.connection.jpa")
public JpaProperties appJpaProperties() {
return new JpaProperties();
}
private JpaVendorAdapter createJpaVendorAdapter(JpaProperties jpaProperties) {
AbstractJpaVendorAdapter adapter = new HibernateJpaVendorAdapter();
adapter.setShowSql(jpaProperties.isShowSql());
adapter.setDatabase(jpaProperties.getDatabase());
adapter.setDatabasePlatform(jpaProperties.getDatabasePlatform());
adapter.setGenerateDdl(jpaProperties.isGenerateDdl());
return adapter;
}
My session scoped class instead of context holder:
#Component
#Scope(value = "session", proxyMode = ScopedProxyMode.TARGET_CLASS)
public class PreferredDatabaseSession implements Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
private DatabaseEnvironment preferredDb;
public DatabaseEnvironment getPreferredDb() {
return preferredDb;
}
public void setPreferredDb(DatabaseEnvironment preferredDb) {
this.preferredDb = preferredDb;
}
}
If I understand your requirement correctly, you intend to define two data sources and for a given request you want to route your queries to a particular data source based on some condition.
The solution is:
File application.properties
#database1 properties
app.database1.connection.url = url1
app.database1.connection.username = username1
app.database1.connection.password = password1
#database2 properties
app.database2.connection.url = url2
app.database2.connection.username = username2
app.database2.connection.password = password2
#default
default.datasource.key=dataSource1
File CommonRoutingDataSource.java
public class CommonRoutingDataSource extends AbstractRoutingDataSource {
#Override
protected Object determineCurrentLookupKey() {
return DataSourceContextHolder.getDataSourceName();
}
public void initDataSources(final DataSource dataSource1, final DataSource dataSource2,
final String defaultDataSourceKey) {
final Map<Object, Object> dataSourceMap = new HashMap<Object, Object>();
dataSourceMap.put("dataSource1", dataSource1);
dataSourceMap.put("dataSource2", dataSource2);
this.setDefaultTargetDataSource(dataSourceMap.get(defaultDataSourceKey));
this.setTargetDataSources(dataSourceMap);
}
}
File DataSourceContextHolder.java
public class DataSourceContextHolder {
private static final ThreadLocal<String> contextHolder = new ThreadLocal<>();
private DataSourceContextHolder() {
// Private no-op constructor
}
public static final void setDataSourceName(final String dataSourceName) {
Assert.notNull(dataSourceName, "dataSourceName cannot be null");
contextHolder.set(dataSourceName);
}
public static final String getDataSourceName() {
return contextHolder.get();
}
public static final void clearDataSourceName() {
contextHolder.remove();
}
}
File DataSourceConfig.java
public class DataSourceConfig {
#Autowired
private Environment env;
#Autowired
#Bean(name = "dataSource")
public DataSource getDataSource(final DataSource dataSource1, final DataSource dataSource2) {
final CommonRoutingDataSource dataSource = new CommonRoutingDataSource();
dataSource.initDataSources(dataSource1, dataSource2, env.getProperty("default.datasource.key"));
return dataSource;
}
#Bean(name = "dataSource1")
public DataSource getDataSource1() throws SQLException {
// The exact DataSource class imported shall be as per your requirement - HikariCP, or Tomcat etc.
final DataSource dataSource = new DataSource();
dataSource.setDriverClassName();
dataSource.setUrl(env.getProperty("app.database1.connection.url"));
// Set all data source attributes from the application.properties file
return dataSource;
}
#Bean(name = "dataSource2")
public DataSource getDataSource2() throws SQLException {
// The exact DataSource class imported shall be as per your requirement - HikariCP, or Tomcat etc.
final DataSource dataSource = new DataSource();
dataSource.setDriverClassName();
dataSource.setUrl(env.getProperty("app.database2.connection.url"));
// set all data source attributes from the application.properties file
return dataSource;
}
}
Now, somewhere in your code (either an Aspect or Controller), you need to dynamically set the data source conditionally:
DataSourceContextHolder.setDataSourceName("dataSource1");
Note: It's better to declare the data source names as enums rather than strings "dataSource1", "dataSource2", etc.
The below snippet works for me
first.datasource.jdbc-url=jdbc-url
first.datasource.username=username
first.datasource.password=password

Trying to use SpringBoot with SpringData with Elasticache:
application.properties:
spring.redis.host=XXXX-dev.XXXX.clusXXXcfg.XXX.cache.amazonaws.com
spring.redis.port=6379
CacheConfiguration:
#Configuration
#PropertySource("classpath:application.properties")
public class CacheConfiguration {

private String redisHostName;
#Bean
public RedisTemplate<String, Company> redisTemplate() {
RedisTemplate<String, Company> template = new RedisTemplate();
template.setConnectionFactory(jedisConnectionFactory());
return template;
}
#Bean
JedisConnectionFactory jedisConnectionFactory() {

factory.setHostName(redisHostName);
factory.setUsePool(true);
return factory;
}
#Bean
public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
return new PropertySourcesPlaceholderConfigurer();
}
}
Service call:
#Autowired
RedisTemplate<String, Company> redisTemplate;
private ValueOperations valueOperations;
#PostConstruct
private void init() {
valueOperations = redisTemplate.opsForValue();
}
#Override
public String createOtp(Company company) {
String token = UUID.randomUUID().toString();
valueOperations.set(token, company);
valueOperations.getOperations().expire(token, 5, TimeUnit.MINUTES);
return token;
}
Error:
org.springframework.data.redis.ClusterRedirectException: Redirect: slot 7228 to 10...:6379.*
redis.clients.jedis.exceptions.JedisMovedDataException: MOVED 7228 10...:6379.*
The question is - what is wrong with configuration?
You're running your Elasticache in Redis Cluster mode (only Redis Cluster responds with MOVED) but the connection factory is configured in standalone mode.
Spring Boot can auto-configure all the things you've set up manually for you. Basically, remove your CacheConfiguration class (or at least remove the majority of code):
#Configuration
public class CacheConfiguration {
#Bean
public RedisTemplate<String, Company> redisTemplate(RedisConnectionFactory connectionFactory) {
RedisTemplate<String, Company> template = new RedisTemplate();
template.setConnectionFactory(connectionFactory);
return template;
}
}
And then configure the following properties in your application.properties file:
spring.redis.cluster.nodes=<node_host>:<port> # Comma-separated list of "host:port" pairs to bootstrap from.
Spring Boot loads application.properties by default and the Redis auto-config configures a RedisTemplate<Object, Object> bean by default. Specializing beans is a valid use-case – do not duplicate what's already provided by the auto-config, especially if you want to achieve what auto-config does.

I am following this link

I have implemented the code But STILL Both my service functions are using the same Database(one which is marked primary)
Service Class
public class TableService{
#Autowired
private Table1Repo t1Repo;
#Transactional(readOnly = false)
public void saveTable1(Table1 t,int a, Table1 t2){

}
}
#Transactional(readOnly = true)
public Table1 getTable(int id){

I'm the writer of the link you refered.
Which data source do you use with Table1Repo?
You have to inject the specific bean "dataSource" to you JDBC call.
I guess #Primary "writeDataSource" is injected to your Repository.
Try to change #Primary to "dataSource" or find a way to inject "dataSource" to your repository.
you can also try in this way:
Spring Boot 2 with Multiple DataSource for Postgres Data Replication
and here is source code in github:
spring-boot-multi-data-source

There is an custom repository interface that implements JPARepository.
I have autowired the custom repository in controller and tried to call findAll().But the method returns 0 although there are 3 records in DB.
I am using spring web for rest service calls.
Entity class is created with #Entity and #Table annotations.It has an embedded key which is annotated using #EmbeddedId annotation.
#Repository
public interface EntityRepository extends JpaRepository<EntityTable, Long> {
#SuppressWarnings("unchecked") EntityTable save(EntityTable entityTable);
}
Entity table is the name of my table mapped with db table.
