我是 Spring/Maven 的新手，正在学习本教程: Serving Web Content with Spring MVC .
每次我运行mvn spring-boot:run，我都会得到这个错误:
Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:1.5.2.RELEASE:run (default-cli) on project gs-serving-web-content: Could not exec java: Application finished with exit code: 1 ->
我尝试添加类路径，尝试运行 mvn install clean spring-boot:run，在类似情况下做了很多人们在 stackoverflow 上建议的其他事情，花了 8 个多小时- 没用。
这是我的主类Application.java:
package hello;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class Application {
public static void main(String[] args) throws Exception{
SpringApplication.run(Application.class, args);
}
}
这是我的 GreeetingController.java 类:
package hello;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
@Controller
public class GreetingController {
@RequestMapping("/greeting")
public String greeting(@RequestParam(value="name", required=false, defaultValue="World") String name, Model model) {
model.addAttribute("name", name);
return "greeting";
}
}
这是我的 pom.xml 文件:

这是我的 HTML 模板:
<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<title>Getting Started: Serving Web Content</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
<p th:text="'Hello, ' + ${name} + '!'" />
</body>
</html>
一个项目的结构是
src/main/java/hello/pom.xml
src/main/java/hello/Application.java
src/main/java/hello/GreetingController.java
src/main/resources/templates/greeting.html
最佳答案
有时端口可能已被使用，请确保在运行应用程序之前终止所有 java 进程。
