或者把下面老師的mybatis-config.xml的配置覆蓋你自己的

<?xml?version="1.0"?encoding="UTF-8"?>
<!DOCTYPE?configuration
????????PUBLIC?"-//mybatis.org//DTD?Config?3.0//EN"
????????"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
????<!--?配置全局屬性?-->
????<settings>
????????<!--?使用jdbc的getGeneratedKeys獲取數(shù)據(jù)庫(kù)自增主鍵值?-->
????????<setting?name="useGeneratedKeys"?value="true"?/>

????????<!--?使用列標(biāo)簽替換列別名?默認(rèn):true?-->
????????<setting?name="useColumnLabel"?value="true"?/>

????????<!--?開(kāi)啟駝峰命名轉(zhuǎn)換:Table{create_time}?->?Entity{createTime}?-->
????????<setting?name="mapUnderscoreToCamelCase"?value="true"?/>
????</settings>
</configuration>

你看看pom.xml里的依賴有沒(méi)有錯(cuò)

<dependency>
????<groupId>org.springframework.boot</groupId>
????<artifactId>spring-boot-starter-test</artifactId>
????<scope>test</scope>
</dependency>

我也和你一樣…現(xiàn)在卡在這里

你應(yīng)該這么寫
