I would like to get a simple integration test with Tomcat and Spring 4 running, injecting a spring component and use my existing data source configuration from Tomcat. I don't want to configure my DataSource twice.
Everything, including my data source, is configured in the file WebContent/WEB-INF/application-context.xml.

I am using this tutorial http://docs.spring.io/spring/docs/current/spring-framework-reference/html/integration-testing.html#testcontext-ctx-management, but I don't fully understand how I can just run my test in the context of Tomcat that provides my DataSource.
Currently, I am this far:
#RunWith(SpringJUnit4ClassRunner.class)
#WebAppConfiguration
#ContextConfiguration(locations = { "file:WebContent/WEB-INF/application-context.xml"})
public class SimulatorTest {
#Autowired
private ShiftSimulator simulator;
#BeforeClass
public void setup() {
// ???
}
#Test
public void testShiftStart() {
System.out.println("Hello world");
}
}
Currently, I get this error when running the test
java.lang.IllegalStateException: Failed to load ApplicationContext
...
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in URL [file:WebContent/WEB-INF/application-context.xml]: Cannot resolve reference to bean 'dataSource' while setting bean property 'dataSource'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource': Invocation of init method failed; nested exception is javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial

I fully understand that there needs to be a InitialContext, but how can I provide my test with my context that is provided by Tomcat, including my Data Source configuration? I don't want to set my data source connection credentials twice.
Solved it. Just to recap the problem: Spring tries to create the dataSource bean and fails at looking up the JNDI name - because there is no JNDI available.
So what I did for testing, I just created another XML files that overrides the bean dataSource. I ignored the file in version control and ask every developer to copy this file in place:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource"
p:driverClassName="com.sap.db.jdbc.Driver"
p:url="jdbc:sap://xxx:30015"
p:username="sa"
p:password="">
</bean>
</beans>
In the test class, I am providing the additional file reference that overrides dataSource so it never tries to do the failing JNDI lookup:
#RunWith(SpringJUnit4ClassRunner.class)
#WebAppConfiguration
#ContextConfiguration(locations = { "file:WebContent/WEB-INF/application-context.xml", "file:WebContent/WEB-INF/test-datasource.xml" })
public class SimulatorTest {
...
TomcatJNDI offers a comfortable solution for this problem. It's based on Tomcat's JNDI system and initializes only Tomcat's JNDI environment without starting the server. So you can access all your resources as configured in Tomcat's configuration files in tests or from within any Java SE application. Usage is simple, e. g.
TomcatJNDI tomcatJNDI = new TomcatJNDI();
tomcatJNDI.processContextXml(contextXmlFile);
tomcatJNDI.start();
DataSource ds = (DataSource) InitialContext.doLookup("java:comp/env/path/to/datasource");

I have two datasources defined "datasource1" and "datasource2" (in xml configuration from a dependency).
Because of that I don't get JdbcTemplate configured by default so I need to do it manually, I do it like this:
1.
#Bean
public JdbcOperations jdbcOperations(DataSource datasource1) {
return new JdbcTemplate(datasource1);
}
2.
#Bean
public JdbcOperations jdbcOperations(#Qualifier("datasource1") DataSource datasource1) {
return new JdbcTemplate(datasource1);
}
In both cases it fails with:
Parameter 0 of method jdbcOperations in com.example.PersistentConfig required a single bean, but 2 were found:
- datasource1: defined in class path resource [datasources.xml]
- datasource2: defined in class path resource [datasources.xml]
Why the qualifier doesn't work?
I can't change the datasources.xml file to add a primary=true to datasource.
datasources.xml:
<?xml version="1.0" encoding="UTF-8"?>

The reason this wasn't working is because xml configuration always overrides java config (see https://jira.spring.io/browse/SPR-7028).
To solve this I needed to create a bean that has different name then the one in the xml and mark that new bean as #Primary.
So now I will have three datasource beans, two connecting to the same database schema, but only one of the marked Primary so it will be used in default places instead of the xml defined one.
I am trying to configure Spring 4 with Hibernate 5.Made a google research but it didn't help. I am launching my app with JUnit test, just to see if Hibernate works.
Error creating bean with name 'usersDao': Unsatisfied dependency expressed through field 'sessionFactory': Error creating bean with name 'sessionFactory' defined in class path resource [ConfigTest/datasource.xml]: Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: org.hibernate.cfg.Configuration.<init>(Lorg/hibernate/boot/MetadataSources;)V; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [ConfigTest/datasource.xml]: Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: org.hibernate.cfg.Configuration.<init>(Lorg/hibernate/boot/MetadataSources;)V

Also When I use Hibernate 4 I face an error :
Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'offersDao': Injection of autowired dependencies failed; nested exception is java.lang.NoClassDefFoundError: org/hibernate/cache/spi/RegionFactory
but I do have RegionFactory at that address:
enter image description here
Thanful in advance!
It appears that the packagesToScan property wants an array.
In your case, I suppose it would look like this...
<property name="packagesToScan">
<array>
<value>DAO</value>
</array>
</property>
Or maybe simply...
<property name="packagesToScan" value="DAO" />
The problem was in compatability of versions. So I used Spring 4.0.3.RELEASE and Hibernate 4.3.5.Final and the error is gone.
Also I had an error : no current session found. So I've refractored a little a transaction bean :
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean>

I have created a JUnit test in spring with next code:
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(locations = {
"classpath:*/WEB-INF/demo-servlet.xml"})
public class CrudTestJUnit extends AbstractJUnit4SpringContextTests {
#Autowired
protected ShoppingCartDao shoppingCartDao;
#Autowired
private ApplicationContext context;
#Before
public void setUp(){
}
#Test
public void testSomething() {
System.out.println("Evo beanvoa:" + Arrays.toString(context.getBeanDefinitionNames()));
Assert.assertTrue(false);
}
}
In demo-servlet.xml i defined bean:
<bean id="shoppingCartDao" class="com.it355.hibernatecrud.dao.impl.ShoppingCartDaoImpl"></bean>
When i run JUnit test i get this error:
Error creating bean with name 'CrudTestJUnit': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: protected com.it355.hibernatecrud.dao.ShoppingCartDao CrudTestJUnit.shoppingCartDao; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.it355.hibernatecrud.dao.ShoppingCartDao] found for dependency:

Am i wrong in calling configuration file or some other thing? Is there someone who had the same issue.
Also in my configuration file i have component scan configured and my application works and loads beans without any problem but JUnit is making a problem.
It seems that your XML configuration file can't be found or loaded properly, thus you aren't able to do the injections properly.
I suggest just use classpath, if your XML configuration file is within your CLASSPATH there's no need to mention WEB-INF etc'. Like this:
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration("classpath:demo-servlet.xml")
public class CrudTestJUnit extends AbstractJUnit4SpringContextTests {
}
In the end i found out that Configuration from WEB-INF must be loaded like this:
#ContextConfiguration(locations = { "file:src/main/webapp/WEB-INF/demo-servlet.xml"})
How I can fix this exception?
Without Spring Boot everything works.
So problem is in "App" section, am I right?

Spring Boot has Database initialization feature which conflicts with your DataSource config. See DataSourceInitializer class. It tries to obtain data source before its creation.
To fix your app you can
Disable initializer using property
spring.datasource.initialize=false
Exclude data source auto config as you have your own configuration
#EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})

However, I got the following error while running the code:

Am I missing anything?
The easy way to use step scope is like this:
<bean id="myReader" class="org.springframework.batch.item.file.FlatFileItemReader" scope="step">
<property name="resource" value="file:#{jobParameters['input.file']}" />
<property name="linesToSkip" value="0" />
<property name="recordSeparatorPolicy" ref="simpleRecordPolicy" />
<property name="lineMapper" ref="journalSicIemtLineMapper" />
</bean>
Placing the step scope on the beans will delay his creation until the step it his referred is about to start. This is what Late-binding means, so you could access variables in the the ExecutionContext.
As the docs in the StepScope states:
beans with the StepScope will be aop:scoped-proxy. This means a proxy goes around the real object.
So when you define a regular Spring Beans (like you did with jobArg) and put the scope=step on it. You will have to find a way to retrieve the object inside this proxy when you want to set it in another bean (JobArgs)
I have looked all over the Spring references and I have not seen late binding in the constructor arguments so I am not sure it works. I assume you are setting the jobParameters in the JobArgs, in which case it should have the same scope="step"
