No qualifying bean of type 'javax.sql.DataSource' available

I am using spring mvc version 5. I am struggling in an autowire problem. I am following a spring security JDBC tutorial. Here is the AppConfiguration.class:
package com.blog.configuration;
import javax.sql.DataSource;
import org.apache.commons.dbcp2.BasicDataSource;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.core.Ordered;
import org.springframework.core.env.Environment;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.JstlView;
#Configuration
#EnableWebMvc
#ComponentScan({ "com.blog" })
#PropertySource("classpath:db.properties")
public class AppConfiguration implements WebMvcConfigurer {
#Autowired
private Environment env;
#Bean
public InternalResourceViewResolver viewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setViewClass(JstlView.class);
viewResolver.setPrefix("/WEB-INF/views/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
/**
* Configure ResourceHandlers to serve static resources like CSS/ Javascript
* etc...
*/
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
}
/**
* configure spring security custom login page
*/
#Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("/login").setViewName("login-page");
registry.setOrder(Ordered.HIGHEST_PRECEDENCE);
}
#Bean
public DataSource dataSource() {
BasicDataSource dataSource = new BasicDataSource();
dataSource.setDriverClassName(env.getProperty("mysql.driver"));
dataSource.setUrl(env.getProperty("mysql.jdbcUrl"));
dataSource.setUsername(env.getProperty("mysql.username"));
dataSource.setPassword(env.getProperty("mysql.password"));
return dataSource;
}
}
and here is the SecurityConfig.class:
package com.blog.configuration;
import javax.sql.DataSource;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;

}
#Bean

The dataSource autowiring is not working, I don't know why. It gives me error: No qualifying bean of type 'javax.sql.DataSource' available. What is the problem?

Move your bean creation code to root configuration class (SecurityConfiguration in your case.)
#Bean
public DataSource dataSource() {
BasicDataSource dataSource = new BasicDataSource();
dataSource.setDriverClassName(env.getProperty("mysql.driver"));
dataSource.setUrl(env.getProperty("mysql.jdbcUrl"));
dataSource.setUsername(env.getProperty("mysql.username"));
dataSource.setPassword(env.getProperty("mysql.password"));
return dataSource;
}
Move above code to root configuration.
Because beans defined in servlet context is not visible in root/application context as root context is initialized first and then servlet context.
If you define bean in root context you can use(autowire) it in servlet context.
What is mean by root-context and servlet-context
Root context ------ Context's Loaded by ContextLoaderListener
Servlet context --- Context's Loaded by DispatcherServlet
If you want to know what is rootContext and what is servletContext and also to have clear idea about accessing beans between context
Refer my answer from this link

I solved by adding JPA dependency to pom.xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>

i got "requested resource not available" error when i correctly mapped and the file is in correct destination but i get the same problem repeatedly

I mapped the controller to "/home" that returns "home" which is in WEB-INF folder and I made the prefix to "/WEB-INF/" but I get the same error repeatedly and I using spring with maven
home.jsp is inside the /WEB-INF/
and the controller return home when we made "/home" request
and the prefix and suffix are correctly mapped

Whenever I was trying with your code I was getting org.springframework.web.servlet.PageNotFound.noHandlerFound No mapping found for HTTP request on my tomcat console and getting 404 on the browser. By changing URL pattern from /* to / solved the problem.
#Override
protected String[] getServletMappings() {

Spring + Maven + Intellij +HelloWorld

I've some google in the search field about my problem, but i don't get solution. In the spring project (not boot) creating in intellij idea via maven I set up all things (see below) like tomcat configuration, java config for simple helloWorld etc... But: i got result only with exploded war and not in the welcome directory: i saw it at localhost:8080 (not at localhost:8080/welcome).
if i set artifact as war I get usual tomcat home page and nothing about my project.
code snpippets below:
Controller:
package com.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
#Controller
public class HomeController {
#RequestMapping("/")
public String welcome(Model model){
model.addAttribute("hello", "Hello");
model.addAttribute("anyone", "anyone");
return "welcome";
}
}

Run configuration window:
Folder structure

I would suggest you not to bother yourself with Spring Configuration files and use Spring Boot where you have it already configured for you.
For instance, this 'hello world' sample should do what you want: https://github.com/pgrimard/spring-boot-hello-world
Also, consider http://start.spring.io/ for generating a skeleton of your project.

I try to display the welcome page, but always get

Spring framework unable to start embedded container

I'm following Spring in Action 4th Edition Chapter 5, but I'm stuck at the very first example.
Here is my Eclipse Luna project structure:

When using Spring Boot you should not include the other Spring dependencies directly, but rely on Boot's own dependency management. When using the provided "starters" you can be sure that all needed libraries will be included in a matching version.
Instead of including spring-mvc artifact in your pom.xml:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
</dependency>
use the dedicated Boot starter for webapps, spring-boot-starter-web:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
More details in the the official guide
I believe other parts of your pom.xml are superfluous as well (spring-boot-starter, javax.servlet-api, spring-boot-maven-plugin)

If You are using another application which listens to the port that is the same as Tomcat listens, this may also be the problem.
