Question

有人知道如何配置Java Spring Boot来读取JSP文件吗？互联网上的方法不适用于我。我已经将tomcat碧玉依赖项添加到porm.xml中。

我的JSP文件：home.jsp，

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
I love java
</body>
</html>

在PORM.XML

中添加了依赖关系

<!-- https://mvnrepository.com/artifact/org.apache.tomcat.embed/tomcat-embed-jasper -->
<dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-jasper</artifactId>
    <scope>provided</scope>
</dependency>

<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-tomcat -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <version>2.1.3.RELEASE</version>
</dependency>

我的控制器：HomeController.java

package com.example.demo;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class HomeController {
    @RequestMapping("home")
    @ResponseBody
    public String home() {
        System.out.println("hi");
        return "home.jsp";
    }
}

请在这里说明问题是什么？我正在使用STS IDE。添加tomcat碧玉对我不起作用。

Answer 1

从您的控制器方法中删除@ResponseBody

@Controller
public class HomeController {

    @RequestMapping("home")
    public String home() {
        System.out.println("hi");
        return "home.jsp";
    }
 }

Answer 2

使用模型和视图返回jsp页面。

在下面的代码中，列表是jsp页面的名称。

@RequestMapping( value="/dataCreate", method = {RequestMethod.POST })
        public ModelAndView createTemplate(HttpServletRequest request,HttpServletResponse response)
        {
            MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
            MultipartFile cuscsvfile = multipartRequest.getFile("cuscsvfile");
            ModelAndView modelView=new ModelAndView("redirect:list");
            String templateName = request.getParameter("templateName");
            String msg = messageSource.getMessage("new.template.creation.success", new Object[]{templateName}, Locale.ENGLISH);
            modelView.addObject("msg", msg);
            //return "redirect:/list";
            return modelView;
        }

Answer 3

更新application.properties

spring.mvc.view.suffix=.jsp
spring.mvc.view.prefix=/WEB-INF/jsp/

并返回不带扩展名的jsp名称，例如“ home”而不是“ home.jsp”

Answer 4

删除 @ResponseBody 批注，并使用以下值更新您的 application.properties 文件

spring.mvc.view.prefix = / WEB-INF / jsp /

spring.mvc.view.suffix = .jsp

Answer 5

尝试一下，您可以不带.jsp返回。

# full example
cmake_minimum_required(VERSION 3.14)

project(my-app-project VERSION 0.0.1 LANGUAGES CXX)

find_package(useful-library REQUIRED)

add_executable(my-application main.cpp)

target_link_libraries(my-application PUBLIC useful-library::useful-library)

if (WIN32)
# copy the .dll file to the same folder as the executable
add_custom_command(
    TARGET my-application POST_BUILD
    COMMAND ${CMAKE_COMMAND} -E copy_directory
    $<TARGET_FILE_DIR:useful-library::useful-library>
    $<TARGET_FILE_DIR:my-application>)
endif()

为此，我们必须在@RequestMapping("home") public String home() { System.out.println("hi"); return "home"; }文件中进行一些配置，

application.properties

（但这不是下面问题的确切答案。这只是关于如何修改代码的想法。）
