hibernate.cfg.xml alternative in java file - java

I am using spring framework and for database I am using hibernate.cfg.xml in the following way
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>
<property name="show_sql">false</property>
<property name="hbm2ddl.auto">update</property>
<mapping class="com.lynas.test.Student" />
</session-factory>
</hibernate-configuration>
Now is there any way to write this code in the java file. Like a bean or something??


The Answer is YES. from http://java.dzone.com/articles/springhibernate-application

NO the above database configration cannot be moved to a java file BUT can be moved to dispactcher servelet.Actually that whole hibernate.cfg.xml is not required from spring 2.5 version upwards.
You can do the set up of the hibernate properties inside the dispatcher servlet like this. The below code uses mysql dialect so replace it with your requirement also replace name of the database,username and password of the database.

Named Pipes Provider: Could not open a connection to SQL Server [53], When connecting to two databases on same server

I am trying to create two database connections using JdbcTemplate in spring MVC. I have two databases on same test server. when I try to connect both at same time the second connection throws error
Named Pipes Provider: Could not open a connection to SQL Server [53]. ; nested exception is com.microsoft.sqlserver.jdbc.SQLServerException: Named Pipes Provider: Could not open a connection to SQL Server [53].
Surprisingly when I connect one with test DB server and another with production DB server, both connections work. I don't know what actually causing it.

Spring MVC Hibernate without xml using DriverManagerDataSource how to map properties

I have these configurations inside spring-mvc-crud-demo-servlet.xml file which I would like to transfer to a Java config class:
<!-- Define Spring MVC view resolver -->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/view/" />
<property name="suffix" value=".jsp" />
</bean>
<!-- Step 1: Define Database DataSource / connection pool -->
<bean id="myDataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
destroy-method="close">
<property name="driverClass" value="com.mysql.cj.jdbc.Driver" />
<property name="jdbcUrl" value="jdbc:mysql://localhost:3306/web_User_tracker?useSSL=false&serverTimezone=UTC" />
<property name="user" value="springstudent" />
<property name="password" value="springstudent" />
<!-- these are connection pool properties for C3P0 -->
<property name="minPoolSize" value="5" />
<property name="maxPoolSize" value="20" />
<property name="maxIdleTime" value="30000" />
</bean>
<!-- Step 2: Setup Hibernate session factory -->
<bean id="sessionFactory"
class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
<property name="dataSource" ref="myDataSource" />
<property name="packagesToScan" value="com.luv2code.springdemo.entity" />
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
</props>
</property>
</bean>
<!-- Step 3: Setup Hibernate transaction manager -->
<bean id="myTransactionManager"
class="org.springframework.orm.hibernate5.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
<!-- Step 4: Enable configuration of transactional behavior based on annotations -->
<tx:annotation-driven transaction-manager="myTransactionManager" />
<!-- Add support for reading web resources: css, images, js, etc ... -->
<mvc:resources location="/resources/" mapping="/resources/**"></mvc:resources>
I have these Java config files:
#Configuration
#EnableWebMvc
#ComponentScan("myappname")
public class DemoAppConfig implements WebMvcConfigurer {
}
public class MySpringMvcDispatcherServletInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
#Override
protected Class<?>[] getRootConfigClasses() {
// TODO Auto-generated method stub
return null;
}
#Override
protected Class<?>[] getServletConfigClasses() {
return new Class[] { DemoAppConfig.class };
}
#Override
protected String[] getServletMappings() {
return new String[] { "/" };
}
}
#Configuration
public class DatabaseConfig {
#Bean
public DriverManagerDataSource getDataSource() {
DriverManagerDataSource bds = new DriverManagerDataSource();
bds.setDriverClassName("org.postgresql.Drive");
bds.setUrl("jdbc:postgresql://localhost:5432/myappname");
bds.setUsername("postgres");
bds.setPassword("mypass");
return bds;
}
}
I'm not sure however how to map properties like minPoolSize or the SessionFactory bean.
I also have this hibernate.cfg.xml file:
<hibernate-configuration>
<session-factory>
<!-- Database connection settings -->
<property name="connection.driver_class">org.postgresql.Driver</property>
<property name="connection.url">jdbc:postgresql://localhost/myappname</property>
<property name="connection.username">postgres</property>
<property name="connection.password">mypass</property>
<!-- JDBC connection pool (use the built-in) -->
<property name="connection.pool_size">5</property>
<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.PostgreSQL9Dialect</property>
<!-- Disable the second-level cache -->
<property name="cache.provider_class">org.hibernate.cache.internal.NoCachingRegionFactory</property>
<!-- Echo all executed SQL to stdout -->
<property name="show_sql">true</property>
<!-- Drop and re-create the database schema on startup -->
<property name="hbm2ddl.auto">update</property>
<mapping class="myappname.entity.User"/>
</session-factory>
</hibernate-configuration>
PS I'm using Spring MVC, not Spring Boot. I don't want to use Spring Boot for this project, because I want to understand how to do it with Spring MVC, so please, don't recommend it.

Following is a working code that I used to learn spring - hibernate integration.
You already have the datasource configured and you may modify the code as per your requirement. The transaction and session management is taken care of in this configuration .
package rg.so.poc.txn.config;

import javax.sql.DataSource;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean;
import org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.annotation.EnableTransactionManagement;
#Configuration
#EnableTransactionManagement
public class DataConfig {
#Bean
public DataSource dataSource() {
return new EmbeddedDatabaseBuilder()
.setType(EmbeddedDatabaseType.H2)
.addScript("schema.sql")
//.addScript("data.sql")
.build();
}
#Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource) {
LocalContainerEntityManagerFactoryBean emFactoryBean = new LocalContainerEntityManagerFactoryBean();
emFactoryBean.setDataSource(dataSource);
emFactoryBean.setPackagesToScan(new String[] { "rg.so.poc.txn.entity" });
JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
emFactoryBean.setJpaVendorAdapter(vendorAdapter);
emFactoryBean.setJpaProperties(hibernateProperties());
return emFactoryBean;
}
private final Properties hibernateProperties() {
Properties hibernateProperties = new Properties();
hibernateProperties.setProperty("hibernate.hbm2ddl.auto", "none");
hibernateProperties.setProperty("hibernate.dialect", "org.hibernate.dialect.H2Dialect");
return hibernateProperties;
}
#Bean
public PlatformTransactionManager transactionManager(EntityManagerFactory emf) {

You have a transaction manager specified in your Spring config, but no configuration on when or where to apply transactions.
In your SpringBean.xml you should uncomment <tx:annotation-driven/>:
<tx:annotation-driven transaction-manager="transactionManager"/>
And then you should annotate the CustomerServiceImpl.saveCustomer method as #Transactional:
#Service
public class CustomerServiceImpl implements CustomerService {
...
#Override
#Transactional
public void saveCustomer(Customer customer) {
customerDaoImpl.saveCustomer(customer);
}
...
}

Add the following property in your hibernate.cfg.xml file for Hibernate 4.
<property name="hibernate.current_session_context_class">thread</property>

Add #EnableTransactionManagement annotation in your java configuration file if your configuration based on annotation without xml.
This may help someone

You can add in hibernate.proerties below value. It's worked for me.
hibernate.current_session_context_class=org.springframework.orm.hibernate4.SpringSessionContext
or
hibernate.current_session_context_class=thread

I think the parts I am missing are the following but please overcheck my class
<context:property-placeholder location="classpath:app.properties" />
<context:component-scan base-package="org.uftwf" />
<tx:annotation-driven transaction-manager="hibernateTransactionManager" />
<jee:jndi-lookup id="dataSource" jndi-name="java:jboss/datasources/mySQLDB"
expected-type="javax.sql.DataSource" />

For
<tx:annotation-driven transaction-manager="hibernateTransactionManager" />
annotate your Configuration class, WebMVCConfig, with
#EnableTransactionManagement
For
<context:component-scan base-package="org.uftwf" />
Add the package String to your #ComponentScan field basePackages
For
<context:property-placeholder location="classpath:app.properties" />
annotate your Configuration class with
#PropertySource(value = "classpath:app.properties")
and make your PropertyPlaceholderConfigurer #Bean method static.
For
<jee:jndi-lookup id="dataSource" jndi-name="java:jboss/datasources/mySQLDB"
expected-type="javax.sql.DataSource" />
I think you can do
#Bean
public DataSource dataSource() throws Exception {
Context ctx = new InitialContext();
return (DataSource) ctx.lookup("java:jboss/datasources/mySQLDB");
}
Instead of autowiring your session factory, just call your #Bean method
#Bean
public HibernateTransactionManager transactionManager()
{
HibernateTransactionManager htm = new HibernateTransactionManager();
htm.setSessionFactory(sessionFactory());
return htm;
}

migrate Spring app from XML to annotations

I've inherited a Spring 3 app that uses XML files to define and wire together the beans. I know that since Spring 2 these can mostly be replaced with annotations. I would like Spring to:
detect beans by scanning certain packages for classes with whatever annotation is used to indicate a Spring bean
attempt to autowire-by-name and field in a bean that I have marked with the relevant annotation
What are steps I need to take to make this happen?

The manual has all the info you need: http://static.springsource.org/spring/docs/3.1.0.M1/spring-framework-reference/html/beans.html#beans-annotation-config
The TL;DR version is that you need to add <context:annotation-config/> to your spring config and then annotate your beans with #Component and in your setter of properties annotate with #Autowired

I shall give you a xml configuration with it anotation based config equivalent respectively, so that you will easily see how to change your bean from xml to java and vice-versa

this file is named springrest-sevlet. actually you can give the name
you want followed by "-servlet" and mention that name in the file
web.xml
` <web-app>
<display-name>Gescable</display-name>
<servlet>
<servlet-name>springrest</servlet-name>
<servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springrest</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>`
the two files should be place in the folder "WEB-INF".
Now the equivalent with anotation based config
`/*

I think the first thing to do is to go slow. Just pick one service at a time and migrate it as you have cause to touch it. Mucking with a ton of spring config is a sure way screw yourself in production with a dependency you only need once in a while.
