Question

我有一个启动弹簧启动Hello World程序，它抛出以下错误：

<link rel="preload" as="style" href="…">

我只在Mac上发行，而不是在Windows PC中发布。在我的Mac上，我尝试过使用Eclipse和IntelliJ IDEA CE。我在这里看了这两篇文章：

How to resolve java.lang.IllegalStateException: No Java compiler available for configuration options compilerClassName

No Java compiler available for configuration options compilerClassName: [null] and compiler: [null]

但这些解决方案对我没有用。

我在这里发布我的代码：的pom.xml

No Java compiler available for configuration options compilerClassName: [null] and compiler: [null]

配置：

package com.mohnish.springbootmaven;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;

@Controller
public class HelloController {

@GetMapping("/")
public String hello() {
    return "hello";
 }
}

Jsp Page：

package com.mohnish.springbootmaven;

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

@SpringBootApplication
public class SpringBootMavenApplication  extends         SpringBootServletInitializer {

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

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

最后我的application.properties：

<%@ page language="java" contentType="text/html; charset=UTF-8" 
pageEncoding="UTF-8"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" 
"http://www.w3.org/TR/html4/loose.dtd">

<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>Hello</title>
</head>
<body>
    Hello World!
</body>

</html>

我也尝试将jsp文件移至spring.mvc.view.prefix=/WEB-INF/jsp spring.mvc.view.suffix=.jsp而不是/WEB-INF/。

任何指针都将受到赞赏。感谢。
