I have written a small code to check #Autowired annotation in Spring, here is my piece of code.
package beans;
//import org.springframework.beans.factory.annotation.AutoWired;
import org.springframework.beans.factory.annotation.Autowired;
//import org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor;
import org.springframework.beans.factory.annotation.Qualifier;
//import org.springframework.beans.factory.annotation.*;
public class Car {
#Autowired
#Qualifier(value="e1")
private Engine engine;
//no need to have setters or constructors here
public void printData()
{
System.out.println("Engine model year: " +engine.getModelyear());
}
}
package beans;
public class Engine {
private String modelyear;
//generate setter and getter
public void setModelyear(String modelyear) {
this.modelyear = modelyear;
}
public String getModelyear() {
return modelyear;
}
}
package test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import beans.Car;
//import beans.Test;
public class Client {
/**
* #param args
*/
public static void main(String[] args) {
ApplicationContext ap = new ClassPathXmlApplicationContext("resource/spring.xml");
Car c=(Car)ap.getBean("c");
c.printData();
}
}
<!--spring.xml-->

I am learning DI and new to spring while trying out CI I have written following code and I think I am correct in syntax still it's showing bean creation error. why it is unable to create bean..??
The code is
Constuctor.java

Try this way
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN"
"http://www.springframework.org/dtd/spring-beans-2.0.dtd">
<!-- Ordered parameters -->
<beans>
<bean id="t" class="beans.Constructor">

<constructor-arg>

You are trying to use Constructor Dependency Injection without creating any such constructor in your DTO (Constructor.java)
The method you defined above:
public void Constructor(String name, int age, String email){
this.name=name;
this.age=age;
this.email=email;
}
is just a simple method/function not a constructor, try to remove the word void.
Note:
To remove any ambiguities for constructor matching, it is more prefer to use indexes with constructor's parameters like:
<bean id="t" class="beans.Constructor">
<constructor-arg value="Alok" index="0"/>
<constructor-arg value="24" index="1"/>
<constructor-arg value="alok#gmail.com" index="2"/>
</bean>
My configuration is:
spring-4.2.3
mybatis-3.3.0
mybatis-spring-1.2.3
mapper looks like:
package com.vsi.idp.map.server.mapper;
//imports...
public interface SeniorMapper extends BaseMapper<Long, Senior>
{
#Results({...})
#Select(...)
public List<Senior> query(...);
}
ServiceImpl looks like:
package com.vsi.idp.map.server;
//imports...
#Service("querySenior")
public class SeniorQueryServiceImpl extends RemoteServiceServlet implements SeniorQueryService
{
#Autowired
SeniorMapper mapper;
#Override
public List<Senior> query(Address address, String careType){...}
}
applicationContext.xml looks like:
<beans ... default-lazy-init="true">
<!-- MyBatis Mapper Interfaces -->
<mybatis:scan base-package="com.vsi.idp.map.server.mapper" />
//other configurations
</beans>
Spock unit test looks like below,and runs as expected
#ContextConfiguration(locations = "file:war/WEB-INF/applicationContext.xml")
public class SeniorQueryServiceImplTest extends Specification{
#Autowired
SeniorQueryServiceImpl service
def "query by full address"(){
//blabla
}
}
But when start web application,I got this warning:
WARNING: No MyBatis mapper was found in '[com.vsi.idp.map.server.mapper]' package. Please check your configuration.
So,how to solve this problem?
UPDATEit is a gwt web application,full error stack is:

you can try add it!

please anyone tell me why i am getting this exception?
Simply change
<value>
auditAdvice
</value>
to
<value>auditAdvice</value>
It seems like spring is using whitespaces and newline symbols as ID here.
Further information on that topic is available here.
Hope that helps.
I'm trying to run a simple Spring + Hibernate tutorial => Maven Spring Hibernate annotation example
My beans definition file BeanLocations.xml is like this :
<beans xmlns="http://www.springframework.org/schema/beans"

</beans>
My main method:
public static void main( String[] args )
{
ApplicationContext appContext = new ClassPathXmlApplicationContext("classpath*:BeanLocations.xml");
StockBo stockBo = (StockBo)appContext.getBean("stockBo");
}
I have a defined service with an interface:
public interface StockBo {
public void save(Stock stock);
public void update(Stock stock);
public void delete(Stock stock);
public Stock findByStockCode(String stockCode);
}
And his implementation:
#Service("stockBo")
public class StockBoImpl implements StockBo {
#Autowired
StockDao stockDao;
public void setStockDao(StockDao stockDao){
this.stockDao = stockDao;
}
#Override
public void save(Stock stock) {
stockDao.save(stock);
}
........
There is any problem with this because spring throws a Exception when StockBo)appContext.getBean("stockBo") :

What is the problem? How can I ensure that Spring recognize my service with component scan?
FYI: StockBo is in com.sample.springhibernate.bo and StockBoImpl in com.sample.springhibernate.bo.impl
If you turn your log level to DEBUG, you'll more than likely find a line like
DEBUG o.s.b.f.xml.XmlBeanDefinitionReader - Loaded 0 bean definitions from location pattern [classpath*:BeanLocations.xml]
That is, your ClassPathXmlApplicationContext did not find any resources that match classpath*:BeanLocations.xml and therefore didn't load any context.
You'll need to provide a resource location String value that properly identifies and locates the context configuration file.
