What location to put spring bean configuration file

I am implementing a simple application to do CRUD operations, using Spring framework.

Source code:

User.java is the model class.

package com.vipin.model;

    public class User {

    private int ssn;
    private String firstName;
    private String lastName;
    private String emailId;

    public int getSsn() {
        return ssn;
    }
    public void setSsn(int ssn) {
        this.ssn = ssn;
    }
    public String getFirstName() {
        return firstName;
    }
    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }
    public String getLastName() {
        return lastName;
    }
    public void setLastName(String lastName) {
        this.lastName = lastName;
    }
    public String getEmailId() {
        return emailId;
    }
    public void setEmailId(String emailId) {
        this.emailId = emailId;
    }
}

Dao layer:

package com.vipin.dao;
import com.vipin.model.User;

public interface DBOpsDao {
    boolean add(User user);
    boolean find(int ssnId);
}

The class which implements (skelton) implementation is:

package com.vipin.dao;

import java.sql.Connection;
import java.sql.SQLException;

import javax.annotation.Resource;
import javax.sql.DataSource;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.vipin.model.User;

public class DefaultDBOpsDaoImpl implements DBOpsDao {

    private DataSource dataSource;

    public DataSource getDataSource() {
        return dataSource;
    }

    @Resource(name="dataSource")
    public void setDataSource(DataSource dataSource) {
        this.dataSource = dataSource;
        System.out.println("Datasource value is " + dataSource);
    }

    public boolean add(User user) {

        ApplicationContext context = new ClassPathXmlApplicationContext("spring.xml");

        return false;
    }

    public boolean find(int ssnId) {
        // TODO Auto-generated method stub
        return false;
    }
}

Sample Main class:

package com.vipin.app;

import com.vipin.dao.DBOpsDao;
import com.vipin.dao.DefaultDBOpsDaoImpl;
import com.vipin.model.User;

public class MainApp {

    public static void main(String[] args) {

        System.out.println("Inside main...");
        DBOpsDao dao = new DefaultDBOpsDaoImpl();

        User user = new User();
        user.setFirstName("xxx");
        user.setLastName("yyy");
        user.setSsn(1);
        user.setEmailId("[email protected]");

        dao.add(user);
    }

}

I am using maven to build this, so the java source code is in:

src/main/java (top level package com.vipin)

When i run this program it is throwing exception complaining that spring.xml doesn't exist. I used ApplicationContext, one of implementation ClassPathXmlApplicationContext.

In which location do i need to put spring.xml file?

Any inputs would be helpful.

Place the xml file at the root of your classpath

For maven that is src/main/resources/ if the directory doesn't exist yet, create it.

src/main/resources/applicationContext.xml

Also src/main/resources/spring/ works as well.

You will need to add spring.xml file at the location - src/main/resources folder. You can have your directory structure inside this directory as - src/main/resources/com/vipin/dao.

src/main/java directory is preferred for java classes.

If you are debugging from eclipse, make sure that you are adding your folder in the project's classpath.

<classpathentry excluding="**" kind="src" output="target/classes" path="src/main/resources">
   <attributes>
      <attribute name="maven.pomderived" value="true"/>
   </attributes>
</classpathentry>

If you create your maven project using maven archetype and you import into eclipse, you need to edit your .classpath file.

You have to initilalize application context properly in your main method. You can check this link for example.
