我是 Spring Boot 新手，尝试在 Spring Boot 中启动一个简单的项目，但无法将项目作为 Java 应用程序启动，并收到下面提到的错误消息，

Project Structure

SpringBootWebApplication.java

package main.java.com.test;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

@SpringBootApplication
public class SpringBootWebApplication extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(SpringBootWebApplication.class);
    }

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

}

WelcomeController.java

package main.java.com.test;

import java.util.Map;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class WelcomeController {

    // inject via application.properties
    @Value("${welcome.message:test}")
    private String message = "Hello World";

    @RequestMapping("/")
    public String welcome(Map<String, Object> model) {
        model.put("message", this.message);
        return "welcome";
    }

}

我在这里做错了什么以及如何解决这个错误？我已尝试了之前查询中提供的答案，但无法解决此问题。

最佳答案

转到项目属性 -> 项目方面 -> 从运行时取消选中 tomcat。

关于java - Spring 启动执行: org. apache.tomcat.util.scan.StandardJarScanner.setJarScanFilter(Lorg/apache/tomcat/JarScanFilter;V，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/50911254/
