使用Spring Boot是否可以使用JAR打包来提供JSP？

java spring spring-boot
2022-09-01 07:30:16

我熟悉 Spring Boot JSP 示例应用程序

但是，该示例使用打包。是否可以对 执行相同的操作 ？WAR<packaging>JAR</packaging>

我的目标是将 s 放在下面以简化我的应用的结构。JSPsrc/main/resources/jsp


答案 1

正如@Andy Wilkinson所说，JSP存在一些局限性。请将您的应用程序打包为 ，并以 执行方式。这在春季网站上有记录。warjar

使用Tomcat，如果您使用war打包，它应该可以工作，即可执行的war将起作用（...）。可执行 jar 将不起作用，因为 Tomcat 中存在硬编码的文件模式。

已弃用的旧答案

是的，这是可能的与Spring Boot。

看看这个例子：https://github.com/mariuszs/spring-boot-web-jsp-example。

为此，请使用spring-boot-maven-plugin或gradle等效项。

有了这个插件，jar是可执行的，可以提供JSP文件。

$ mvn package
$ java -jar target/mymodule-0.0.1-SNAPSHOT.war

（请注意上述命令.war中工件的扩展名）或只是

$ mvn spring-boot:run

答案 2

如果您的 springboot 正在构建您的项目并在本地服务器中正确运行它，那么 YES。您需要做的是使用 生成项目。然后在目标文件夹中，您有可运行的xxxx.jar。现在，您要做的是将xxxx.jar文件放在服务器中，或者放在您想要的位置以及*.jsp文件放在同一层次结构中。然后尝试您的项目将毫无问题地运行。mvn -U clean packagesrc/main/webapp/WEB-INF/jsp/java -jar xxxx.jar
