我已经很多年没有使用Java了，但现在我想使用Java/Groovy进行web开发。现在，Spring Boot似乎是最受推荐的框架选项，因此，我正在尝试让我的第一个Hello World在pluralsight.com上完成创建第一个Spring Boot应用程序的课程后运行

过去，我在控制台应用程序中使用Groovy。我曾经使用过Eclipse，但是我没有任何使用Maven或Gradle的经验。现在我安装了Spring工具套件3

我无法运行第一个示例应用程序，相反，程序会以错误消息终止（见下文）。我应该打开

http://localhost:8080

在浏览器中，但找不到服务器。下面是我的档案

你能帮我找出这个问题吗？我在Mac上，这个项目是作为STS中的Maven项目设置的

App.java

package com.boot;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * Hello world!

 */
@SpringBootApplication
public class App 
{
    public static void main( String[] args )
    {
        // System.out.println("test") does work
        SpringApplication.run(App.class, args);
    }

因为您使用的是Spring Boot，所以它内置了Tomcat Web服务器。尝试通过在application.properties文件中添加属性来更改端口nber

server.port=8090

确保服务、组件、实体等都是JavaBean

Java bean：

1.3不支持java 11，查看反射访问警告似乎很有可能。Java 11仅在Spring Boot 2.1中受支持

要么使用JDK8，要么将该应用程序升级为使用SpringBoot2.1

默认情况下，Spring Boot 1.3.0.RELEASE需要Java 7和Spring Framework 4.1.5或更高版本。您可以将SpringBoot与Java6一起使用，并进行一些额外的配置。有关更多详细信息，请参见第79.9节“如何使用Java6”。为Maven（3.2+）和Gradle（1.12+）提供了显式构建支持。 [提示]

尽管您可以将SpringBoot与Java6或Java7一起使用，但如果可能的话，我们通常推荐Java8

如前所述，我建议不要为Spring Boot使用任何1.x版本。今年八月是生命的终点

首先，您正在使用严重过时的软件版本。STS现在是版本4，您应该使用Boot 1.5.x或2.0.x。（从start.spring.io或从Eclipse引导向导创建项目将获得最新版本。）您的本地maven存储库可能已损坏。这可能会有帮助。相反，按照本课程学习SpringBoot：谢谢。我选择这些版本是为了能够遵循课程。在完成Pluralsight课程后，我可能会学习Nikhil提到的课程，该课程没有那么老（34个月对25个月）。谢谢，使用JDK 8一切正常。我试着在接下来的短期课程中坚持使用推荐的工具，但我会记住很快切换到SpringBoot2。
