Spring Boot: 1.3.2.RELEASE
Vaadin : 7.6.3
Mysql: mysql-java-connector-5.1.38
HikariCP: 2.4.3
So I create a Table with only id and name columns. Then a vaadin componant Table to show the content of table. Until now everything is fine. Then I tried to filter the table with a vaadin Filter, and it works if the connection pool is com.vaadin.data.util.sqlcontainer.connection.SimpleJDBCConnectionPool, and doesnot if it is com.vaadin.data.util.sqlcontainer.connection.J2EEConnectionPool which I use HikariCP as the data source.
DBConfig.java
#Configuration
#EnableTransactionManagement
public class DatabaseConfig {
#Bean
public HikariConfig hikariConfig() {
HikariConfig config = new HikariConfig();
config.setDriverClassName("com.mysql.jdbc.Driver");
config.setJdbcUrl("jdbc:mysql://localhost:3306/test?autoReconnect=true&useSSL=false");
config.setUsername("root");
config.setPassword("root");
config.setMaximumPoolSize(20);
config.setPoolName("connectionPool");
return config;
}
#Bean
public DataSource dataSource() {
HikariDataSource dataSource = new HikariDataSource(hikariConfig());
return dataSource;
}
ApplicationUI.java
#Autowired
private J2EEConnectionPool connectionPool;
#Override
protected void init(VaadinRequest arg0) {
TableQuery tq = new TableQuery("medecine", connectionPool);// it does not work if I use HikariCP as the J2EEConnectionPool
JDBCConnectionPool pool = new SimpleJDBCConnectionPool("com.mysql.jdbc.Driver",
"jdbc:mysql://localhost:3306/test?autoReconnect=true&useSSL=false", "root", "root");
TableQuery tq = new TableQuery("medecine", connectionPool);// it works if I use **SimpleJDBCConnectionPool**.
container = new SQLContainer(tq);
table = new Table();
table.setContainerDataSource(container);
table.setWidth(100, Unit.PERCENTAGE);
mainLayout.addComponent(table);
Button addFilter = new Button("filter", new ClickListener() {
private static final long serialVersionUID = -7071683058766115266L;
#Override
public void buttonClick(ClickEvent arg0) {
Filter filter = new SimpleStringFilter("name", "medecine2", true, false);
container.addContainerFilter(filter);
}
});
mainLayout.addComponent(addFilter);
}
The reason I choose HikariCP as the data source is for a better performance and I'm not sure that the vaadin connection pool will be better than HikariCP. Or, it is limited to vaadin connection pool for the filtering function?

I am implementing a backend with two database connections. One to a MS Access DB and another one to a MySQL DB. I've setup two configuration classes and the application is running without any error message, but does not create the tables for my entities in mysql db.
Project structure:
my.backend
|
--> configuration
--> controller
--> exceptions
--> model
| |
| --> mysql
| --> msaccess
|
--> repo
| |
| --> mysql
| --> msaccess
|
--> service
My configuration files are looking like this:
MySQL Configuration:
imports [...]
#Configuration
#EnableJpaRepositories(
entityManagerFactoryRef = "mysqlEntityManagerFactory",
transactionManagerRef = "mysqlTransactionManager",
basePackages = "my.backend.repo.mysql"
)
public class MySqlJpaConfig {
#Autowired
private Environment env;
#Bean
#Primary
#ConfigurationProperties(prefix = "mysql")
public LocalContainerEntityManagerFactoryBean mysqlEntityManagerFactory() {
LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
em.setDataSource(mysqlDataSource());
em.setPackagesToScan("my.backend.model.mysql");
em.setPersistenceUnitName("mysql");
em.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
HashMap<String, Object> jpaProperties = new HashMap<>();
jpaProperties.put("hibernate.ddl-auto",
env.getProperty("mysql.jpa.hibernate.ddl-auto"));
jpaProperties.put("hibernate.dialect",
env.getProperty("mysql.jpa.properties.hibernate.dialect"));
em.setJpaPropertyMap(jpaProperties);
return em;
}

return dataSource;
}
#Primary
#Bean
public PlatformTransactionManager mysqlTransactionManager() {
JpaTransactionManager transactionManager
= new JpaTransactionManager();
transactionManager.setEntityManagerFactory(
mysqlEntityManagerFactory().getObject());
return transactionManager;
}
}
MS Access Configuration:
#Configuration
#EnableJpaRepositories(
entityManagerFactoryRef = "msaccessEntityManagerFactory",
transactionManagerRef = "msaccessTransactionManager",
basePackages = "my.backend.repo.msaccess"
)
#EnableTransactionManagement
public class MsAccessJpaConfig {
#Autowired
private Environment env;
#Bean
#ConfigurationProperties(prefix = "mysql")
public LocalContainerEntityManagerFactoryBean msaccessEntityManagerFactory() {

em.setDataSource(msaccessDataSource());
em.setPackagesToScan("my.backend.model.msaccess");
em.setPersistenceUnitName("msaccess");
//em.setPersistenceProvider(new HibernatePersistenceProvider());
em.setJpaVendorAdapter(new HibernateJpaVendorAdapter());

#Bean
public PlatformTransactionManager msaccessTransactionManager() {
JpaTransactionManager transactionManager

transactionManager.setEntityManagerFactory(
msaccessEntityManagerFactory().getObject());
return transactionManager;
}
}
And my application.properties file:
spring.jpa.show-sql=true
spring.jpa.open-in-view=false
# MySQL config
mysql.url=jdbc:mysql://localhost:3306/my_database
mysql.username=
mysql.password=
mysql.driver-class-name=com.mysql.cj.jdbc.Driver
mysql.jpa.hibernate.ddl-auto=update
mysql.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL8Dialect
# MS Access config
msaccess.url=jdbc:ucanaccess://c:/users/username/documents/test.accdb
msaccess.driver-class-name=net.ucanaccess.jdbc.UcanaccessDriver
msaccess.jpa.properties.hibernate.dialect=org.hibernate.dialect.SQLServerDialect
When I run my application without the custom configuration and only one vanilla database connection (only MySQL) everything works fine. Also if I run this and perform a get request I get a Error that the table does not exist (obviously), so the connection to MySQL is there but the application just does not create the tables I need. Btw MS Access is working the same way, but I do not want a table generation there.
Am I missing some configuration for the connection?
Thanks for your help!
Cheers, niklas
My guess is that you have to use hibernate.hbm2ddl.auto instead of hibernate.ddl-auto in your jpa properties configuration, since that is the name hibernate looks for
I'm trying to read from DB2 with a stored procedure ( SP ) that returns records based on page size and start page among other input parameters. My goal is however to request all the records in one call and load another table in Mysql using Spring Batch. Seems straight forward enough, however when I run the job below it returns the correct number of records as per the SP but the records are skewed and duplicated as if the transactions are not working properly. The reader uses one #Primary Datasources ( DS ), for the DB2 read and another DS for the JpaItemWriter destination (LocalContainerEntityManagerFactoryBean).
My understanding is that DB2 and Mysql returns a ResultSet so don't know why I am forced to add these lines to avoid Invalid Parameter Type or Cursor position errors....
reader.setVerifyCursorPosition(false);
reader.setRefCursorPosition(0);
I am reading from DB2 then inserting into a MySql table based on the supplied AccountCashRowMapper. It's a strange situation that almost works, the listener doesn't report any errors.
Spring Batch is supposed to inherently manage the transactions for me, however what configuration or code is missing to make this work ?

I'm creating a multi tenant spring boot - JPA application.
In this application, I want to connect to MySQL Databases using DB name which is sent through API request as header.
I checked many multi tenant project samples online but still can't figure out a solution.
Can anyone suggest me a way to do this?
You can use AbstractRoutingDataSource to achieve this. AbstractRoutingDataSource requires information to know which actual DataSource to route to(referred to as Context), which is provided by determineCurrentLookupKey() method. Using example from here.
Define Context like:
public enum ClientDatabase {
CLIENT_A, CLIENT_B
}
Then you need to define Context Holder which will be used in determineCurrentLookupKey()
public class ClientDatabaseContextHolder {
private static ThreadLocal<ClientDatabase> CONTEXT = new ThreadLocal<>();
public static void set(ClientDatabase clientDatabase) {
Assert.notNull(clientDatabase, "clientDatabase cannot be null");
CONTEXT.set(clientDatabase);
}
public static ClientDatabase getClientDatabase() {
return CONTEXT.get();
}
public static void clear() {
CONTEXT.remove();
}
}
Then you can extend AbstractRoutingDataSource like below:
public class ClientDataSourceRouter extends AbstractRoutingDataSource {
#Override
protected Object determineCurrentLookupKey() {
return ClientDatabaseContextHolder.getClientDatabase();
}
}
Finally, DataSource bean configuration:
#Bean
public DataSource clientDatasource() {
Map<Object, Object> targetDataSources = new HashMap<>();
DataSource clientADatasource = clientADatasource();
DataSource clientBDatasource = clientBDatasource();
targetDataSources.put(ClientDatabase.CLIENT_A,
clientADatasource);
targetDataSources.put(ClientDatabase.CLIENT_B,
clientBDatasource);
ClientDataSourceRouter clientRoutingDatasource
= new ClientDataSourceRouter();
clientRoutingDatasource.setTargetDataSources(targetDataSources);
clientRoutingDatasource.setDefaultTargetDataSource(clientADatasource);
return clientRoutingDatasource;
}

Following this logic, I can solve it now. Some of the versions need to be upgraded and the codes as well.
Spring Boot version have changed.
org.springframework.boot
spring-boot-starter-parent
2.1.0.RELEASE
Mysql version has been removed.
And some small changed in MultitenantConfiguration.java
#Configuration
public class MultitenantConfiguration {
#Autowired
private DataSourceProperties properties;
/**
* Defines the data source for the application
* #return
*/
#Bean
#ConfigurationProperties(
prefix = "spring.datasource"
)
public DataSource dataSource() {
File[] files = Paths.get("tenants").toFile().listFiles();
Map<Object,Object> resolvedDataSources = new HashMap<>();
if(files != null) {
for (File propertyFile : files) {
Properties tenantProperties = new Properties();
DataSourceBuilder dataSourceBuilder = DataSourceBuilder.create(this.getClass().getClassLoader());
try {
tenantProperties.load(new FileInputStream(propertyFile));
String tenantId = tenantProperties.getProperty("name");
dataSourceBuilder.driverClassName(properties.getDriverClassName())
.url(tenantProperties.getProperty("datasource.url"))
.username(tenantProperties.getProperty("datasource.username"))
.password(tenantProperties.getProperty("datasource.password"));
if (properties.getType() != null) {
dataSourceBuilder.type(properties.getType());
}
resolvedDataSources.put(tenantId, dataSourceBuilder.build());
} catch (IOException e) {
e.printStackTrace();
return null;
}
}
}
// Create the final multi-tenant source.
// It needs a default database to connect to.
// Make sure that the default database is actually an empty tenant database.
// Don't use that for a regular tenant if you want things to be safe!
MultitenantDataSource dataSource = new MultitenantDataSource();
dataSource.setDefaultTargetDataSource(defaultDataSource());
dataSource.setTargetDataSources(resolvedDataSources);
// Call this to finalize the initialization of the data source.
dataSource.afterPropertiesSet();
return dataSource;
}
/**
* Creates the default data source for the application
* #return
*/
private DataSource defaultDataSource() {
DataSourceBuilder dataSourceBuilder = DataSourceBuilder.create(this.getClass().getClassLoader())
.driverClassName(properties.getDriverClassName())
.url(properties.getUrl())
.username(properties.getUsername())
.password(properties.getPassword());
if(properties.getType() != null) {
dataSourceBuilder.type(properties.getType());
}
return dataSourceBuilder.build();
}
}
This change is here due to the DataSourceBuilder has been moved to another path and its constructor has been changed.
Also changed the MySQL driver class name in application.properties like this
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
I prepared website in Spring/Maven with use of MySQL db, Tomcat. I decided to use Heroku free account, because I have domain, db and Java in one place. Problem is that Heroku uses postgresql for free but mysql is payable. I would like to ask you help and explanation clearly what I should change in my application's code(pom.xml, hibernate.properties etc) to use postgresql instead of mysql. Below I show files I think should be changed. Do I have to add any new files? I beg your indulgence.

dataSource.setUsername(environment.getRequiredProperty("jdbc.user.name"));
dataSource.setUrl(environment.getRequiredProperty("jdbc.url"));
return dataSource;
}
// 2. EntityManagerFactory

factoryBean.setJpaVendorAdapter(vendorAdapter);
factoryBean.setJpaProperties(properties);
factoryBean.setDataSource(dataSource());
factoryBean.afterPropertiesSet();

I am trying to implement multiple database with Spring Boot Hikari CP. I am getting
Caused by: org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type [javax.sql.DataSource] is defined: expected single matching bean but found 2: hikari_primary,hikari_secondary
For your reference I am attaching my spring boot datasource configuration files,
please dont go over primary and secondary naming conventions(they dont represent priorities), my requirement it to have two connection pool for two different databases.
Any help is appreciated

Spring boot is auto-configuring your application via #EnableAutoConfiguration (note that this annotation is already included in the composed #SpringBootApplication annotation). So my guess would be that you have some dependency that spring is trying to auto-configure (e.g. JPA) which uses/needs DataSource. If you can live with this, you can add #Primary to on of your DataSource Bean provider methods in order to satisfy that dependency.
So, for instance:
#Bean(name="hikari_primary")
#Primary
public HikariDataSource getHikariDataSourcePrimary() {...
Even if this should work, it would be recommended to remove auto-configuration for e.g. JPA or whatever spring boot is trying to auto-configure but you don't use/need and configure everything manually as it suits your application needs. Have two databases is certainly a custom configuration and does not conform to the spring boot easy-out-of-the-box approach.
