Spring Boot是否可以使用JAR包装来提供JSP

我熟悉Spring Boot JSP示例应用程序

但是，该示例使用WAR包装。 是否可以对JAR做同样的事情？

我的目标是将JSP放在src/main/resources/jsp以简化我的应用程序的结构。

Answer 1

正如@Andy Wilkinson所说，存在与JSP相关的限制。 请将您的应用程序打包为war并执行jar 。 这是在春季网站上记录的。

使用Tomcat它应该可以使用war包装，即可执行的战争将起作用（…）。 由于Tomcat中的硬编码文件模式，可执行jar将无法工作 。

不推荐的，旧答案

是的，这可以通过Spring Boot实现。

看一下这个例子： https ： //github.com/mariuszs/spring-boot-web-jsp-example 。

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

使用此插件jar是可执行的，可以提供JSP文件。

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

要不就

 $ mvn spring-boot:run 

Answer 2

使用Tomcat ，还可以将WEB-INF/jsp的内容放到/src/main/resources/META-INF/resources （以Maven为例）。 META-INF / resources基本上被视为传统的webapps文件夹。

示例代码： https ： //github.com/ghillert/spring-boot-jsp-demo

Answer 3

您最好的选择是将包装类型更改为战争，它应该无需进一步更改即可运行。

如上述评论中所述，存在一些限制：

Answer 4

如果你的springboot正在构建你的项目并在本地服务器上正确运行它，那么YES 。 您需要做的是使用mvn -U clean package构建项目。 然后在目标文件夹中，你有你的runnable xxxx.jar。 现在你需要做的是将你的xxxx.jar文件放在服务器中或你想要的位置以及同一层次结构中的src/main/webapp/WEB-INF/jsp/ * .jsp文件。 然后尝试java -jar xxxx.jar您的项目将运行没有问题。

27.3.5 JSP限制

运行使用嵌入式servlet容器的Spring Boot应用程序（并打包为可执行存档）时，JSP支持存在一些限制。

使用Tomcat它应该可以使用war包装，即可执行的war会起作用，并且也可以部署到标准容器（不限于但包括Tomcat）。

由于Tomcat中的硬编码文件模式，可执行jar将无法工作。

使用Jetty它应该可以使用war包装，即可执行的战争将起作用，并且也可以部署到任何标准容器。

Undertow不支持JSP。

创建自定义error.jsp页面不会覆盖error handling的默认视图，而应使用自定义错误页面。

Answer 6

我在使用jar包装的 Spring Boot Application上成功使用JS P，将我的JSP文件放在src / main / webapp / WEB-INF / JSP目录中，并将我的应用程序配置为如下

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

我的控制器是：

 @Controller public class HelloController { @RequestMapping(value = { "/", "/hello**" }, method = RequestMethod.GET) public ModelAndView welcomePage() { ModelAndView model = new ModelAndView(); model.addObject("title", "Spring Security Example"); model.addObject("message", "This is Hello World!"); model.setViewName("hello"); System.out.println("° ° ° ° welcomePage running. model = " + model); return model; } . . . 

我的hello.jsp是

 <%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%> <%@page session="true"%>   
Title : ${title}
 
${message}
 
Options: " >Home | " >Administration | " >Super user  | " >Logout  
   

我的pom.xml文件是

 br.com.joao-parana my-spring-boot-app jar 1.0 my-spring-boot-app Maven Webapp http://maven.apache.org  org.springframework.boot spring-boot-starter-parent 1.3.4.RELEASE   1.8   . . .  org.springframework.boot spring-boot-starter-test test   org.springframework spring-test     org.springframework.boot spring-boot-starter-web   jstl jstl 1.2   org.apache.tomcat.embed tomcat-embed-jasper provided   org.springframework.boot spring-boot-starter-actuator    my-spring-boot-app   org.springframework.boot spring-boot-maven-plugin    

我希望这能有所帮助！

Answer 7

Spring Boot与JSP相当不错，而且只需要在配置下面就可以了

1 – tomcat-embad-jasper依赖

  org.apache.tomcat.embed tomcat-embed-jasper provided  

2 – 添加以下配置是application.properties

 spring.mvc.view.prefix: / spring.mvc.view.suffix: .jsp 

这仍然有一些疑问，然后在链接下面查看它

Answer 9

如果出于某种原因，你无法处理战争包装，那就是黑客攻击。 这个家伙完全赞同为旧版本的spring-boot做这件事。

一种方法是个性化tomcat并将BOOT-INF/classes添加到tomcat的ResourceSet。 在tomcat中，所有扫描的资源都被放入称为ResourceSet的东西中。 例如，servlet 3.0规范中的应用程序jar包的META-INF / resources被扫描并放入ResourceSet中。

现在我们需要找到一种方法将胖jar的BOOT-INF / classes目录添加到ResourceSet中。 我们可以通过tomcat LifecycleListener接口在Lifecycle.CONFIGURE_START_EVENT事件中执行此操作，获取BOOT-INF / classes URL，然后将此URL添加到WebResourceSet。 这里有一个完整的例子，但你可以这样做：

 import org.apache.catalina.Context; import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty; import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory; import org.springframework.boot.web.server.WebServerFactory; import org.springframework.boot.web.server.WebServerFactoryCustomizer; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; @Configuration @ConditionalOnProperty(name = "tomcat.staticResourceCustomizer.enabled", matchIfMissing = true) public class TomcatConfiguration { @Bean public WebServerFactoryCustomizer staticResourceCustomizer() { return new WebServerFactoryCustomizer() { @Override public void customize(WebServerFactory factory) { if (factory instanceof TomcatServletWebServerFactory) { ((TomcatServletWebServerFactory) factory) .addContextCustomizers(new org.springframework.boot.web.embedded.tomcat.TomcatContextCustomizer() { @Override public void customize(Context context) { context.addLifecycleListener(new StaticResourceConfigurer(context)); } }); } } }; } } 

然后使用LifecycleListener，如下所示：

 import java.io.File; import java.net.MalformedURLException; import java.net.URL; import org.apache.catalina.Context; import org.apache.catalina.Lifecycle; import org.apache.catalina.LifecycleEvent; import org.apache.catalina.LifecycleListener; import org.apache.catalina.WebResourceRoot.ResourceSetType; import org.springframework.util.ResourceUtils; public class StaticResourceConfigurer implements LifecycleListener { private final Context context; StaticResourceConfigurer(Context context) { this.context = context; } @Override public void lifecycleEvent(LifecycleEvent event) { if (event.getType().equals(Lifecycle.CONFIGURE_START_EVENT)) { URL location = this.getClass().getProtectionDomain().getCodeSource().getLocation(); if (ResourceUtils.isFileURL(location)) { // when run as exploded directory String rootFile = location.getFile(); if (rootFile.endsWith("/BOOT-INF/classes/")) { rootFile = rootFile.substring(0, rootFile.length() - "/BOOT-INF/classes/".length() + 1); } if (!new File(rootFile, "META-INF" + File.separator + "resources").isDirectory()) { return; } try { location = new File(rootFile).toURI().toURL(); } catch (MalformedURLException e) { throw new IllegalStateException("Can not add tomcat resources", e); } } String locationStr = location.toString(); if (locationStr.endsWith("/BOOT-INF/classes!/")) { // when run as fat jar locationStr = locationStr.substring(0, locationStr.length() - "/BOOT-INF/classes!/".length() + 1); try { location = new URL(locationStr); } catch (MalformedURLException e) { throw new IllegalStateException("Can not add tomcat resources", e); } } this.context.getResources().createWebResourceSet(ResourceSetType.RESOURCE_JAR, "/", location, "/META-INF/resources"); } } }
