						我是弹簧靴的初学者。我初始化了一个新项目并尝试运行它,但它无法成功工作。我把它作为弹簧启动应用程序运行,它开始执行。在底部的编译器/状态栏中,它显示处理和重试。它最多10次并抛出以下错误:
TanmayTestApplication.java
package com.example.tanmay_test;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class TanmayTestApplication {
    public static void main(String[] args) {
        SpringApplication.run(TanmayTestApplication.class, args);
    }
}
DemoControler.java
package com.example.cntr;

    public String index() {
        return "By Tanmay!";
    }
