Spring Boot JSP

Question

有没有什么简单的方法生成Spring Boot的Mvc项目？jsp视图？

我试图以类似于Spring靴Rest项目的方式创建项目，但这对我来说并不容易。我尝试过使用官方的Spring启动 Mvc jsp 示例，但是当我尝试运行此示例时，我得到这样的异常：

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>

创建以下结构/src/主/资源/元 INF/资源

现在上面的文件夹就相当于你的WebContent文件夹了。在这个里面你可以放置你的静态内容。在这里添加WEB-INF文件夹，现在您可以像放置任何其他WEB项目一样放置您的JSP文件。

在application.properties文件中添加以下内容:

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

spring.mvc.view.suffix=.jsp

Answer 2

据我所知，spring boot默认页面技术是thymeleaf，官方建议我们使用它。如果您想使用jsp，可以进行一些配置。

以下步骤可能有用。

1. Creating  src/main/webapp/WEB-INF/jsp folder.
2. Modify application.properties file.

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

3.添加对 jsp 的罐子支持。您可以将以下 maven 存储库添加到项目 pom.xml 文件中。

<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>

希望它有所帮助。如有任何疑虑，请随时让我知道。

这篇博客文章解释了你应该采取什么步骤以及为什么。这相当容易，我已经自己修好了。

添加专家依赖项

为了启用 JSP 支持，我们需要在 pom.xml 中为新项目添加一些依赖项。

<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/we b-INF/JSP/下
