我正在尝试从我的 Controller 渲染 jsp 页面，但我发现发生了这种奇怪的事情。当我运行应用程序时，它显示页面的实际 html 代码而不是显示 View 。这很奇怪我可能做错了什么。因此，当我运行应用程序时，基本上会显示欢迎页面的整个 html 代码。
package com.example.DemoService;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import java.util.Map;
@Controller
public class HelloController {
@RequestMapping("/test")
public String welcome(Map<String, Object> model) {
model.put("message", "Raaj");
return "welcome";
}
}
Jsp
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<body>
Hello ${message}
</body>
</html>

最佳答案
您有很多事情需要做:
添加您的
application.properties(假设您的 jsp 位于src/webapp/WEB-INF/jsp)spring.mvc.view.prefix=/WEB-INF/jsp/ spring.mvc.view.suffix=.jsp
尝试输入
tomcat-embed-jasper与<scope>compile</scope><dependency> <groupId>org.apache.tomcat.embed</groupId> <artifactId>tomcat-embed-jasper</artifactId> <scope>compile</scope> </dependency>
如果您使用 <scope>provided</scope> 运行它，至少在 IntelliJ 中似乎存在错误。它不会识别jsps。如果您使用 maven ( mvn spring-boot:run ) 运行，则无论 scope 怎样，它都可以正常运行。
