我正在尝试来自 spring.io 的本教程（https://spring.io/guides/tutorials/spring-security-and-angular-js/），我收到了这个错误。

我正在使用 Wro4j 库，这是一个基于 java 的工具链，用于预处理和打包前端资产。它生成要嵌入到 JAR 文件中的 angularjs 库文件和引导文件。

index.hml (src/main/resources/static/index.html)

<!DOCTYPE html>
<html lang="en">
    <head>
    <meta charset="UTF-8">
    <title>Hello eStudent</title>
    <link href="css/angular-bootstrap.css" rel="stylesheet">
    <style type="text/css">
        [ng\:cloak], [ng-cloak], .ng-cloak {
            display: none !important;
        }
    </style>
   </head>

<body ng-app="hello ">
<div class="container">
    <h1>Greeting</h1>
    <div ng-controller="home" ng-cloak class="ng-cloak">
        <p>The ID is {{greeting.id}}</p>
        <p>The content is {{greeting.content}}</p>
    </div>
</div>

<script src="js/angular-bootstrap.js" type="text/javascript"></script>
<script src="js/hello.js"></script>

</body>
</html>

hello.js 应用程序文件 (src/main/resources/static/js/hello.js)

angular.module('hello',[])
    .controller('home', function($scope) {
        $scope.greeting = {id: 'xxx', content: 'Hello World!'}
    })

为了使 wro4j 正常工作，还需要设置一些属性文件。这些文件是：

  • main.less
  • 错误属性
  • wro.xml

以下是这些“wro4j”配置文件的内容。

main.less 为空

错误属性

#List of preProcessors
preProcessors=lessCssImport
#List of postProcessors
postProcessors=less4j,jsMin

wro.xml

<groups xmlns="http://www.isdc.ro/wro">
  <group name="angular-bootstrap">
    <css>webjar:bootstrap/3.3.7-1/less/bootstrap.less</css>   
    <css>file:@project.basedir@/src/main/wro/main.less</css>
    <js>webjar:jquery/2.2.4/jquery.min.js</js>
    <js>webjar:angularjs/1.4.9/angular.min.js</js>
    <js>webjar:angularjs/1.4.9/angular-route.min.js</js>
    <js>webjar:angularjs/1.4.9/angular-cookies.min.js</js>
   </group>
</groups>

spring-boot应用的主应用文件如下

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

@SpringBootApplication
public class EStudentApplication {

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

当我运行应用程序时，浏览器除了静态内容“问候”之外什么都没有显示。不显示动态内容。并且浏览器控制台以粗体显示上面显示的错误。

有人可以帮我解决这个问题吗？
