Solve problems encountered in Spring-boot startup: Cannot determine embedded database driver class for database type NONE

The problem is as follows:

Description:

Cannot determine embedded database driver class for database type NONE

Action:

If you want a embedded database, put a supported one on the classpath. If you have the database settings to is loaded from a particular profiles you may need to active it (no profiles is currently Active).

Process finished with exit code 1

------------------------I'm a split line------------------

Find the so-called solution on the Web:

@SpringBootApplication (exclude = {datasourceautoconfiguration.class, hibernatejpaautoconfiguration.class}, Scanbasepackages = {"Com.ppdai.pointshop.web.controller"}) public class Pointshopwebapplication {public static void Main (string[] args) {Springapplication.run (pointshopwebapplication.class, args);}}

But unfortunately, it's useless.

So with maven download good springboot source code, and then debugging breakpoints in, see what is the situation, and finally found the problem lies:

Because I'm a new project and I don't have a data source configured, but I want to start the project without configuring the data source, what should I do? The method found on the Internet is not valid, so I made a bold guess: it must be a place to load the bean, because this is a new project, so I think it is very possible to start loading, and start loading only the Pom file within the dependencies can be done. Here is my dependency dependency:

<dependencies><!--https://mvnrepository.com/artifact/org.springframework.boot/ Spring-boot-autoconfigure--><dependency><groupid>org.springframework.boot</groupid>< artifactid>spring-boot-autoconfigure</artifactid><version>1.5.4.release</version></ dependency><!--Https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-->< dependency><groupid>org.springframework.boot</groupid><artifactid>spring-boot</ Artifactid><version>1.5.4.release</version></dependency><dependency><groupid> org.springframework.boot</groupid><artifactid>spring-boot-starter-aop</artifactid>< Version>1.5.4.release</version></dependency><dependency><groupid> Org.springframework.boot</groupid><artifactid>spring-boot-starter-data-redis</artifactid> <version>1.5.4.release</version></dependency><dependency><groupid>org.mybatis.spring.boot</groupid><artifactid>mybatis-spring-boot-starter</ Artifactid><version>1.3.0</version></dependency><dependency><groupid> org.springframework.boot</groupid><artifactid>spring-boot-starter-web</artifactid>< Version>1.5.4.release</version></dependency><dependency><groupid> org.springframework.boot</groupid><artifactid>spring-boot-starter-tomcat</artifactid>< Version>1.5.4.release</version><scope>provided</scope></dependency><dependency ><groupid>org.springframework.boot</groupid><artifactid>spring-boot-starter-test</ Artifactid><version>1.5.4.release</version><scope>test</scope></dependency> <!--Https://mvnrepository.com/artifact/org.springframework/spring-core--><dependency><groupid >org.springframework</groupid><artifactid>spring-core</artifactid><version>4.3.9.release</version></dependency><!--https:/ /mvnrepository.com/artifact/org.springframework/spring-context--><dependency><groupid> org.springframework</groupid><artifactid>spring-context</artifactid><version>4.3.9. Release</version></dependency></dependencies>

A check, and finally found org.mybatis.spring.boot this dependency, comments out can be found, debugging time Beannames obviously a lot less.

<dependency>   <groupId>org.mybatis.spring.boot</groupId>   <artifactId> Mybatis-spring-boot-starter</artifactid>   <version>1.3.0</version></dependency>

Finally, Spring boot is successful!
