Java WebApp，SpringBoot错误

Question

Im working on my first springboot application. I'm working with some book and I was doing everythink step by step and when I run the program it was few errors which I couldn't fix. Probably they're small but still I'm struggling to solve the problem, that's why I'm here.

WebstoreappApplication:

package com.exovsky.webstoreapp;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class WebstoreappApplication {

    public static void main(String[] args) {
        SpringApplication.run(WebstoreappApplication.class, args);
    }

}

HomeController:

package com.exovsky.webstoreapp.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("greeting", "Witaj w sklepie internetowym!");
        model.addAttribute("tagline", "Wyjątkowym i jedynym sklepie 
internetowym");
        return "welcome";
    }

}

Description:

Parameter 0 of constructor in org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration required a bean of type 'javax.sql.DataSource' that could not be found.
- Bean method 'dataSource' not loaded because @ConditionalOnProperty (spring.datasource.jndi-name) did not find property 'jndi-name'
- Bean method 'dataSource' not loaded because @ConditionalOnBean (types: org.springframework.boot.jta.XADataSourceWrapper; SearchStrategy: all) did not find any beans
Action:

Consider revisiting the conditions above or defining a bean of type 'javax.sql.DataSource' in your configuration.

Answer 1

You need a dependency on spring-jdbc for an embedded database to be auto-configured as described here

 <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-jdbc</artifactId>
    <version>4.3.13.RELEASE</version>
    <type>jar</type>
</dependency>
