我熟悉Spring Boot JSP示例应用程序
但是，该示例使用WAR包装。是否可以使用<packaging>JAR</packaging>？
我的目标是将 JSP s放在 src/main/resources/jsp下，以简化我的应用程序的结构。
正如@andy Wilkinson所说，与JSP。请将您的应用程序打包为war并执行为jar。这是在春季站点记录的。
使用tomcat，如果您使用战争包装，即可执行的战争将起作用（...）。由于Tomcat中的硬编码文件模式。
- 27.3.5 JSP限制
- JSP样本
弃用，旧答案
是的，春季启动是可能的。
请看一下此示例：https：//github.com/mariuszs/spring-boot-web-jsp-example。
这样做的使用弹簧启动 - 马文 - plugin或gradle等效。
使用此插件罐可执行，可以使用JSP文件。
$ mvn package
$ java -jar target/mymodule-0.0.1-SNAPSHOT.war
（请注意上述命令中的工件的扩展）或只是
$ mvn spring-boot:run
如果您的Springboot正在构建项目并正确地在本地服务器中运行，则是YAS 。您需要做的是使用 mvn -U clean package。然后，在 target 文件夹中，您具有可运行的xxxx.jar。现在，您要做的就是将xxxx.jar文件放在服务器中或与src/main/webapp/WEB-INF/jsp/ *。JSP文件一起使用的位置。 然后尝试java -jar xxxx.jar您的项目将没有问题。

谢谢。
您最好的选择是将包装类型更改为战争，它应该无需进一步工作即可变化。
如上所述，有一些局限性：
http://docs.spring.io/spring-boot/docs/current/referent/reference/html/boot-features-developing-weblicing-web-applications.html#boot-features-features-jsp-limitations-jsp-limitations
div>如果出于任何原因，您无法处理战争包装，就会有黑客攻击。全部归功于这个家伙为较旧版本的Spring-Boot做到的。
做到这一点的一种方法是个性化tomcat并将BOOT-INF/classes添加到Tomcat的资源集中。在Tomcat中，所有扫描资源都被放入称为资源集的东西中。例如，扫描了Servlet 3.0规范中应用程序JAR软件包的元I-INF/资源，并将其放入资源集中。
现在，我们需要找到一种将脂肪罐的启动INF/类目录添加到Resourceset的方法。我们可以通过tomcat LifecyClelistener接口，在Lifecycle.CONFIGURE_START_EVENT事件中获取boot-inf/class类URL，然后将此URL添加到Webresourceset中。一个完整的例子是这里，但是您可以这样做：
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<WebServerFactory> staticResourceCustomizer() {
return new WebServerFactoryCustomizer<WebServerFactory>() {
@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，例如：
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");
}
}
}
27.3.5 JSP限制
运行使用嵌入式servlet的弹簧启动应用程序 容器（并且被包装为可执行存档），有一些 JSP支持中的限制。
使用tomcat，如果您使用战争包装，则应使用 可执行战争将有效，也可以部署到标准 容器（不限于tomcat）。
由于硬编码文件模式，可执行的jar无法工作 在tomcat中。
使用码头，如果您使用战争包装，即可执行 战争将起作用，也可以部署到任何标准容器中。
Unterthow不支持JSP。
创建自定义错误。JSP页面不会覆盖默认视图 错误处理，应使用自定义错误页面。

春季启动与JSP相当不错，而且很容易，也只需您以下配置
1- tomcat-embad-jasper依赖性
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>
2-添加以下配置为应用程序。
spring.mvc.view.prefix: /
spring.mvc.view.suffix: .jsp
那仍然有疑问，然后在链接下面检查一下
Spring Boot和JSP Integration
我正在使用 JS> js p在 Spring Boot上成功地成功>带有 JAR包装的应用程序，将我的JSP文件放在SRC/MAIN/WEBAPP/WEB-INF/JSP目录上，并将我的应用程序配置为Bellow
@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;
}
. . .
和我的hello.jsp是
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@page session="true"%>
<html>
<body>
<h1>Title : ${title}</h1>
<h1>${message}</h1>
<h2>Options:
<a href="<c:url value="/hello" />" >Home</a> |
<a href="<c:url value="/admin" />" >Administration</a> |
<a href="<c:url value="/super" />" >Super user</a>
<c:if test="${pageContext.request.userPrincipal.name != null}"> |
<a href="<c:url value="/logout" />" >Logout</a>
</c:if>
</h2>
</body>
</html>

如果出于某种原因仍然需要SB2 中的任何原因，我们必须稍微调整LifeCycleEvent方法
@Override
public void lifecycleEvent(LifecycleEvent event) {
if (event.getType().equals(Lifecycle.CONFIGURE_START_EVENT)) {
URL location = this.getClass().getProtectionDomain().getCodeSource().getLocation();
if (new LocalDevelDetection().isDocker()){
try {
//This is necessary to make JSP work in docker --> not sure which of those mounts actually does the trick but I think /YOUR_SB_APP_NAME one works for docker-compose and the other one for "vanilla docker" (non-compose)
context.getResources().createWebResourceSet(WebResourceRoot.ResourceSetType.RESOURCE_JAR, "/<<YOUR_SB_APP_NAME>>", new URL("jar:file:/<<PATH_TO_YOUR_SB_APP>>.jar!/"), "/META-INF/resources");
context.getResources().createWebResourceSet(WebResourceRoot.ResourceSetType.RESOURCE_JAR, "/", new URL("jar:file:/<<PATH_TO_YOUR_SB_APP>>.jar!/"), "/META-INF/resources");
} catch (MalformedURLException e) {
throw new RuntimeException(e);
}
}
else {
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(WebResourceRoot.ResourceSetType.RESOURCE_JAR, "/", location, "/META-INF/resources");
}
}
}
oh和我们的localDevelDetection.isdocker（）方法：
public boolean isDocker(){
try (Stream< String > stream =
Files.lines(Paths.get("/proc/1/cgroup"))) {
return stream.anyMatch(line -> line.contains("/docker"));
} catch (IOException e) {
return false;
}
}

将视图解析器添加到application.properties文件。
spring.mvc.view.prefix: /WEB-INF/jsp/
spring.mvc.view.suffix: .jsp
一次，我们完成了上述代码，我们将使用MAVEN命令构建项目，然后使用Standard Java的Jar Execution命令执行为独立jar。
cd <TO_YOUR_PROJECT_DIR>
mvn clean package spring-boot:repackage
