Controller
package com.tehnocracksolutions.JdbcExample.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import com.tehnocracksolutions.JdbcExample.Model.CreateModel;
#Controller
public class UserController {
#RequestMapping(value="create",method=RequestMethod.POST)
public String createUser(){
CreateModel model = new CreateModel();
model.insertdata();
return "welcome";
}
}
Model: used mySQL for database connection it seems that datasource are not passed correctly
package com.tehnocracksolutions.JdbcExample.Model;
import javax.sql.DataSource;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.JdbcTemplate;
public class CreateModel {
#Autowired
DataSource datasource;
public void insertdata(){
JdbcTemplate jdbcTemplate = new JdbcTemplate(datasource);
jdbcTemplate.execute("insert into data values('nayan','m','m','t')");
}
public DataSource getDatasource() {
return datasource;
}
public void setDatasource(DataSource datasource) {
this.datasource = datasource;
}
}

Answer 1

Use configured spring bean datasource and Do not use
import javax.sql.DataSource;

Answer 2

1st way :
Declare data source in your class files as :
org.springframework.jdbc.datasource.DriverManagerDataSource dataSource;
2nd way :
Or just declare jdbc template in your CreateModel and autowired it with Jdbc template. Then, you need not to declare DataSource in your CreateModel Class.

Answer 3

Your configurations are right. Just check that you have created database in mysql named "mkyong".
