如何爲JSP配置spring boot mvc應用程序？

Question

我是Spring引導（和servlet 3.0）的新手。我正在嘗試用JSP作爲視圖創建spring mvc項目。當我從我的控制器返回視圖時，它不會被解析爲JstlView。

這裏是我做過什麼：

@SpringBootApplication 
public class MyApp extends SpringBootServletInitializer { 

    public static void main(String[] args) { 
     SpringApplication.run(MyApp.class, args); 
    } 

} 

---

@Controller 
public class MainController { 

    @RequestMapping(value="/main" , method = RequestMethod.GET ) 
    public String main(){ 
     return "main"; 
    } 

    @RequestMapping(value="/" , method = RequestMethod.GET ) 
    public String welcome(){ 
     return "welcome"; 
    } 
} 

---

同時創建的.jsp在src\main\webapp\WEB-INF\jsp文件。

谷歌搜索後，我發現我需要在application.properties指定這個所以我添加以下道具：

---

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


logging.level.org.springframework: TRACE 
logging.level.com: TRACE 

即使在此之後它無法正常工作。這是跟蹤。

正如你在跟蹤中看到，這是試圖解決/jsp/welcome.jsp作爲InternalResourceView而不是JstlView。最終失敗爲404。

我需要遵循哪些其他步驟？ SpringBoot-mvc有jsp教程嗎？

P.S.我可以使用web.xml（使用JstlView在我的配置文件中）使用jsp創建spring mvc應用程序。但是我找不到有關jsp的Spring啓動mvc的任何教程。

Answer 1

假設它嵌入的Tomcat，

你需要有以下在pom.xml

<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> 

嵌入式Tomcat的核心包已經沒有JSP渲染支持。

Answer 2

@Bean 
public ViewResolver getViewResolver(){ 
    InternalResourceViewResolver resolver = new InternalResourceViewResolver(); 
    resolver.setPrefix("/WEB-INF/jsp/"); 
    resolver.setSuffix(".jsp"); 
    resolver.setViewClass(JstlView.class); 
    return resolver; 
} 

也需要和你的網頁應在/ web應用/ WEB-INF/JSP/

+

<dependency> 
     <groupId>org.springframework.boot</groupId> 
     <artifactId>spring-boot-starter-tomcat</artifactId> 
    </dependency> 
    <dependency> 
     <groupId>org.apache.tomcat.embed</groupId> 
     <artifactId>tomcat-embed-jasper</artifactId> 
    </dependency> 
    <dependency> 
     <groupId>javax.servlet</groupId> 
     <artifactId>jstl</artifactId> 
    </dependency> 

Answer 3

首先，你需要爲下面加適量行家依賴呈現在JSP春季啓動應用。

<dependency> 
     <groupId>javax.servlet</groupId> 
     <artifactId>jstl</artifactId> 
    </dependency> 
    <dependency> 
     <groupId>org.apache.tomcat.embed</groupId> 
     <artifactId>tomcat-embed-jasper</artifactId> 
    </dependency> 

然後定義視圖類的JstlView如下：

@Bean 
public InternalResourceViewResolver setupViewResolver() { 
     InternalResourceViewResolver resolver = new InternalResourceViewResolver(); 
     resolver.setPrefix ("/ui/jsp/"); 
     resolver.setSuffix (".jsp"); 
     resolver.setViewClass (JstlView.class); 
     return resolver; 
    } 

在這裏找到一個工作示例spring boot mvc jsp integration example

Answer 4

你不需要的ViewResolver。 pom.xml需要Yura所述的相關性，並將jsp文件放在src \ main \ webapp \ WEB-INF \ jsp中。

Answer 5

1. 創建的webapp/WEB-INF /視圖{命名上一個文件夾當U就像} 在src /主

2. 添加JSTL JAR

3. 附加以下的application.properties

   兩行

   spring.mvc.view.prefix：/ WEB-INF /視圖/ spring.mvc.view.suffix：.JSP

   運行在Spring應用程序啓動是..U好走！

   瞭解更多U可以諮詢我的這個項目在GitHub上：雖然我不熟悉Spring啓動，（我更喜歡Spring開發的「遺產」的方式） https://github.com/SudipBiswasRana/Using-JSP-As-View-For-Spring-Project
