我正在尝试使用 spring-boot 读取我的 jsp 文件，因此我启动了该项目，当我检查本地主机时，它实际上返回实际的字符串“index”，但没有将其读取为 index.jsp (作为 jsp 文件)
我创建了 Controller 类“HomeController”并实现了一个名为 homePage 的方法，该方法将具有 @RequestMapping 然后它将返回“index”
家庭 Controller
@RestController
public class HomeController {
@RequestMapping("/showHome")
public String homePage(){
return "index";
}
}
index.jsp 文件
<!DOCTYPE html>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>
<html lang="en">
<body>
<div>
<div>
<h1>Spring Boot JSP Example</h1>

应用程序属性
spring.mvc.view.prefix=/WEB-INF/views/
spring.mvc.view.suffix=.jsp
项目结构
我的浏览器中有“index”字符串，希望加载 jsp 文件 注意:当我用 @Controller 替换 @ResController 时，我收到 Whitelabel 错误页面。
最佳答案
从 application.properties 文件中删除这两行
spring.mvc.view.prefix=/WEB-INF/views/
spring.mvc.view.suffix=.jsp
并从资源包中删除模板文件夹。
然后将此类添加到您的 com.example.demo 包中。
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.ViewResolverRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
@Configuration
@EnableWebMvc
@ComponentScan(basePackages= {"com.example"})
public class WebConfig implements WebMvcConfigurer {
public void configureViewResolvers(ViewResolverRegistry registry) {
registry.jsp().prefix("/WEB-INF/views/").suffix(".jsp");
}
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
}
}
在 Controller 中使用:
@Controller not @RestController
喜欢:
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
public class TestController {
@RequestMapping(value = "/showHome", method = RequestMethod.GET)
public String homePage() {
return "index";
}
}
