我用Google搜索了这个错误，但没有找到任何解决方案来运行该应用程序。我的系统设置

Answer 1

我遇到了同样的问题。刚修好了。该应用程序无法解决弹簧启动，因为版本 - 所以只需尝试使用这些行和版本和范围。你确定＆＃34;测试＆＃34; :)

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <version>${spring.boot.version}</version>
        <scope>test</scope>
</dependency>

Answer 2

方法ResolvableType.forInstance（Object）来自4.2，所以我建议你把你的Spring核心版本更新到4.2.4
