无法启动嵌入式容器;嵌套的异常是java.lang.NoClassDefFoundError:java / nio / charset / StandardCharsets

阿尔沙德·阿里(Arshad Ali)

我从Spring工具套件创建了一个启动器项目,其配置如下所示 启动应用

当我通过更改运行应用程序时

@SpringBootApplication
@RestController
public class FirstApplication {

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

    @RequestMapping("/greet")
    public String helloGreeting() {
        return "Salam REST";
    }
}

它崩溃说

这有什么问题。

似乎您使用了错误的JRE来运行此应用程序。确保使用Java 1.7或更高版本运行它,尤其是通过某些IDE运行它时。由于Java文档的缘故,StandardCharsets自1.7版开始可用。
