弹簧启动 JSP 404 [英] Spring Boot JSP 404
问题描述
我正在尝试在我的 Spring Boot 服务中添加一个 jsp 页面.我的问题是，每次我尝试访问该页面时，都会出现:
I'm trying to add a jsp page in my Spring Boot service. My problem is that every time I try to go to that page I have this:
白标错误页面
这个应用程序没有明确的/error 映射，所以你会看到这是一个后备.
This application has no explicit mapping for /error, so you are seeing this as a fallback.
Tue Apr 21 23:16:00 EEST 2015 出现意外错误(type=Not已找到，状态=404).没有可用的消息
Tue Apr 21 23:16:00 EEST 2015 There was an unexpected error (type=Not Found, status=404). No message available
我已将前缀和后缀添加到我的 application.properties 中:
I have added the prefix and sufix into my application.properties:
spring.view.prefix: /WEB-INF/jsp/
spring.view.suffix: .jsp
这是我的控制器类:
@Controller
public class MarkerController {
@RequestMapping(value="/map")
public String trafficSpy() {
return "index";
}
}
我的应用类:
@SpringBootApplication
public class Application extends SpringBootServletInitializer {
private static Logger logger = Logger.getLogger(Application.class.getName());
public static void main(String[] args) {
logger.info("SPRING VERSION: " + SpringVersion.getVersion());
SpringApplication.run(Application.class, args);
}
}
还有 index.jsp:
And the index.jsp:
<!DOCTYPE html>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<html lang="en">
<body>
<h1>Hello, World!!!</h1>
<p>JSTL URL: ${url}</p>
</body>
</html>
这是src文件结构:
├── src
│ ├── main
│ │ ├── java
│ │ │ └── com
│ │ │ └── example
│ │ │ └── internetprogramming
│ │ │ └── myserver
│ │ │ └── server

推荐答案
确保你的依赖列表中有 jasper 和 jstl:
Ensure that you have jasper and jstl in the list of dependencies:
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</dependency>
