Java webapp,springboot错误

Question

我正在开发我的第一个springboot应用程序。我在写一本书，一步一步地做每一件事，当我运行这个程序的时候，很少有我无法修复的错误。也许他们很小，但我仍然在努力解决问题，这就是我来这里的原因。

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);
    }

}

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";
    }

}

spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration

Answer 1

您需要一个对spring-jdbc的依赖关系，以便像这里描述的那样自动配置嵌入式数据库

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