Question

我在Spring启动应用程序中遇到问题：我无法显示jsp页面，但它运行映射到该页面的Controller方法。

主要班级：

package com.example.souk;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Souk5Application {

    public static void main(String[] args) {
        SpringApplication.run(Souk5Application.class, args);
    }
}

控制器：

package com.example.souk;

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

@Controller
public class Souk5Controller {

    @RequestMapping("/afficher")
    public String test(){
        System.out.println("je suis dans souk 5 controller ");
        return "afficher";
    }
}

application.properties：

spring.datasource.url=jdbc:mysql://localhost:3306/kijiji
spring.datasource.username=root
spring.datasource.password=
spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.jpa.hibernate.ddl-AUTO=update
spring.jpa.properties.hibernate.dialct=org.hibernate.dialect.MySQL5Dialect
server.port=8181
spring.mvc.view.prefix= WEB-INF/jsp/
spring.mvc.view.suffix= .jsp

欢迎任何帮助，我坚持了一段时间。当我打电话给网址＆＃34; http://localhost:8181/afficher＆＃34;在谷歌浏览器中：它显示：白标错误页面，我可以在控制台中看到来自方法的消息＆＃34; je suis dans souk 5 controller＆＃34;。

Answer 1

将以下依赖项添加到您的POM文件中：

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

将JSP模板放在src / main / resources / META-INF / resources / WEB-INF / jsp /

下

在application.properties:中应更新到以下：

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

spring.mvc.view.suffix = .jsp

Answer 2

正如瑞诗凯诗所述，在pom.xml中添加了依赖关系，并执行以下操作。

您需要从SpringBootServletInitializer扩展您的Main类。

@SpringBootApplication 
public class Souk5Application extends SpringBootServletInitializer{

     @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Souk5Application .class);
    }

    public static void main(String[] args) {
        SpringApplication.run(Souk5Application.class, args);
    }
}

注意：确保您的目录正确如下（来源：sitesbay）：

Answer 3

感谢每一个人。最后我发现了我的错误，我无法相信它是application.properties中的一个空格： spring.mvc.view.suffix = .jsp我在.jsp后面有一个空格，我无法想象这种影响。我希望能帮助别人。
