【问题描述】：

我正在尝试执行我的 SpringBoot webapp jar，它会抛出找不到页面的错误。 但在 Spring-Too-Suite 上运行时它会正常工作。

我的主要课程

@SpringBootApplication
    public class WudiDataApplication 

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

application.propertie 文件如下

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

spring.mvc.view.suffix: .jsp

server.port=8080

这是我的 pom.xml

....更新....

我已经创建了如下所示的配置类，但仍然显示相同的错误..

 @Configuration
 @EnableTransactionManagement
 @EnableWebMvc
 public class DbConfig  
.......

【参考方案1】：

实际上我们无法在 Spring Boot 中使用 jsp 创建 jar。尝试创建战争，它需要一些特定的文件夹结构

【参考方案2】：

你需要创建一个配置类来启用 web mvc

@Configuration
@EnableWebMvc
public class WebConfig
