Question

我正在构建Spring Boot + MyBatis + MySQL，我已将配置添加到pom.xml中：

    <dependency>
        <groupId>org.mybatis.spring.boot</groupId>
        <artifactId>mybatis-spring-boot-starter</artifactId>
        <version>1.3.2</version>
    </dependency>

    <!-- 添加 MySQL -->
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>5.1.41</version>
    </dependency>

我的主要功能是这样的：

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

 @SpringBootApplication
 public class DemoApplication {

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

但是当我运行main函数时，我得到以下异常：

我不知道我错在哪里，mybatis-spring版本是1.3.2，maven版本是3.3.9，mybatis版本。 3.4.6我的版本有问题吗？

Answer 1

你应该更新上面的spring boot版本

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.4.7.RELEASE</version>
    </parent>
