REST API 中的线程“主”java.lang.IllegalArgumentException 中的异常答案

【问题标题】：Exception in thread "main" java.lang.IllegalArgumentException in REST APIREST API 中的线程“主”java.lang.IllegalArgumentException 中的异常
【发布时间】：2020-07-18 21:46:15
【问题描述】：

所以我对 REST API 开发非常陌生，对于我的应用程序，我使用了 Spring Boot 初始化程序。我遇到了一个错误，hibernate 无法访问我的 oracle 数据库，后来我发现我错误地添加了一个 derby 依赖项，它在某种程度上与数据库访问发生冲突。在我把它拿出来和与之相关的东西之后，我得到了这个错误。我在这里遗漏了什么重要的东西吗？

另外，我很抱歉这么久了，但我真的很绝望

这是我的错误

这是我的主要课程

@SpringBootApplication
@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "con.example.TNDservice")
public class TnDserviceApplication {

    public static void main(String[] args) {

        SpringApplication.run(TnDserviceApplication.class, args);
    }

}

标签： java spring hibernate spring-boot maven

【解决方案1】：

你的 spring-boot 版本是 2.2.5 但 spring framework 版本是 4.3.0，我认为这个 spring-boot 版本默认 spring framework 版本是 5.xx，你可以尝试为 spring-更新 spring framework 版本- boot 或使用https://start.spring.io/ 生成所需版本的pom。这也可能有助于unresolvable dependency org.springframework.core.KotlinDetector.isKotlinReflectPresent()z

【讨论】：

【解决方案2】：

您不应该在没有非常好的理由的情况下手动覆盖依赖版本。

使用 Spring Boot 预定义的版本经过验证可以很好地协同工作，但是您正在严重降级几个版本。

因此，您可能需要删除这些行：

    <springframework.version>4.3.0.RELEASE</springframework.version>
    <jackson.library>2.9.8</jackson.library>
    <hibernate.version>4.3.6.Final</hibernate.version>
    <jstl-version>1.2</jstl-version>
