我在主类上添加了注释,如下所示:
package com.main;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.bind.annotation.CrossOrigin;
import com.controller.RequestClass;
@CrossOrigin(origins = "http://localhost:4200")
@SpringBootApplication
@Configuration
@EnableAutoConfiguration
@ComponentScan("com.*")
public class MainClass
{
public static void main(String[] args)
{
SpringApplication.run(RequestClass.class, args);
}
}
但是在运行应用程序时,遇到以下错误。
请告诉我是否需要其他文件进行调试

如果springapplicatiom.run是针对主类而不是控制器类的,那会发生什么?看看这个线程https://stackoverflow.com/a/44466367/5126865(我假设您想实现的目标很抱歉,如果道歉了)
