我刚刚开始学习spring,我已经添加了一个jsp文件到我的项目中,但是控制器不能Map到它。我的控制器在 src --> main --> java --> com.example.todo --> controller -->UserController.java中,我的jsp文件在src --> main --> resources --> WEB-INF --> jsp -->***index.jsp中。***我正在观看一个视频,其中有人将jsp文件添加到spring项目,控制器Map它。但在我的情况下,它不是这样做。
这是我的代码-
TodoApplication.java
package com.example.todo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class TodoApplication {
public static void main(String[] args) {
SpringApplication.run(TodoApplication.class, args);
}
}
UserController.java
package com.example.todo.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;
@Controller
public class UserController {
@GetMapping("/index")
public String ind(){
return "index";
}
@GetMapping("/index-html")
@ResponseBody
public String indexHTML(){
StringBuilder body = new StringBuilder();
body.append("<!DOCTYPE html>");
body.append("<html>");
body.append("<body>");
body.append("<h1>HTML page</h1>");
body.append("<p>This is a random text</p>");
body.append("</body>");
body.append("</html>");
return body.toString();
}
}
index.jsp
<!DOCTYPE html>
<html>
<body>
<h1 style="color: blue;">This is jsp file</h1>
</body>
</html>

应用.属性
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
spring.datasource.url=jdbc:h2:mem:db
我在Ubuntu 22.04上使用IntelliJ IDEA社区和JDK 19和Spring 3.1。当我后藤localhost:8080/index-html时,它呈现html代码并按预期执行,但它不是;当我转到localhost:8080/index时,就不会出现这种情况。
我还对www.example.com进行了更改application.properties,添加了前缀和后缀,并添加了tomcat-jasper依赖项。
请帮帮我也会很高兴,如果你能提供一个很好的在线资源,学习Spring Boot 。

最好检查创建的jsp是否在正确的路径下
