Springboot可执行jar无法访问索引页
我使用springboot，restapi和angularjs创建了一个应用程序。我将此项目作为可执行jar。但是当我java -jar patchinit.jar时，它不会重新加载索引页面。它给出了
Whitelabel错误页面（出现意外错误（type = Not Found， status = 404无可用消息）
我错过了什么吗？我几乎拼命地尝试了一切......

1 个答案:
答案 0 :(得分：0)
最后我得到了一个解决方案。我可以通过在pom中添加thymeleaf依赖项来解决此问题
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
什么是Thymeleaf？
Thymeleaf是一个Java库。它是一个XML/XHTML/HTML5模板引擎，能够将一组转换应用于模板文件，以显示应用程序生成的数据和/或文本。
您的html文件中需要进行一次更正：
<link rel="stylesheet"
href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.2/css/bootstrap.min.css">
<link rel="stylesheet"
href="https://cdnjs.cloudflare.com/ajax/libs/angular-material/1.1.5/angular-material.min.css">
请务必使用结束标记<link>关闭此标记</link>。否则你将得到以下错误
出现意外错误（type = Internal Server Error， 状态= 500）。解析文档的异常：template =“index”，第12行 - 第3栏
