스프링 부트로 JSP를 JAR 패키징으로 제공할 수 있습니까?
Spring Boot JSP 샘플 어플리케이션에 대해 잘 알고 있다.
, 이 에서는, 「」, 「」를 하고 있습니다.WAR패키징.같은 일을 할 수 있을까요?<packaging>JAR</packaging>
는 ★★★★★★★★★★★★★★★★★★★★★★★.JSP ssrc/main/resources/jsp내 앱의 구조를 단순화합니다.
@Andy Wilkinson JSP.는 ★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★war하다.jar이것은 스프링 사이트에서 문서화되어 있습니다.
Tomcat에서는 전쟁 패키징을 사용하면 실행 가능한 전쟁(...)이 작동합니다.Tomcat에서 하드 코딩된 파일 패턴 때문에 실행 가능한 jar가 작동하지 않습니다.
권장되지 않는 오래된 답변
네, Spring Boot을 사용하면 가능합니다.
예를 들어 https://github.com/mariuszs/spring-boot-web-jsp-example 를 참조해 주세요.
그러기 위해서는 spring-boot-maven-plugin 또는 gradle 등가물을 사용합니다.
이 플러그인 jar를 사용하면 실행 가능하며 JSP 파일을 처리할 수 있습니다.
$ mvn package
$ java -jar target/mymodule-0.0.1-SNAPSHOT.war
(위의 명령어 .war의 아티팩트 확장자에 주의) 또는
$ mvn spring-boot:run
스프링부트가 프로젝트를 빌드하고 로컬서버에서 올바르게 실행하고 있는 경우는, 「네」를 클릭합니다.당신이 해야 할 일은 다음을 사용하여 프로젝트를 구축하는 것입니다.mvn -U clean package다음으로 타겟 폴더에 실행 가능한xxxx.jar가 있습니다.여기서 해야 할 일은 xxxx.jar 파일을 서버 또는 원하는 위치에 두거나src/main/webapp/WEB-INF/jsp/ *.jsp 파일이 같은 계층에 있습니다.그럼 해봐java -jar xxxx.jar프로젝트는 문제없이 실행됩니다.

감사해요.
패키징 타입을 전쟁으로 변경하는 것이 최선의 방법입니다.더 이상 변경하지 않아도 동작합니다.
위의 코멘트에 기재된 바와 같이 몇 가지 제한이 있습니다.
27.3.5 JSP의 제한
임베디드 서블릿컨테이너를 사용하는(및 실행 가능한 아카이브로서 패키지화되어 있는) Spring Boot 애플리케이션을 실행하는 경우, JSP 서포트에는 몇 가지 제한이 있습니다.
Tomcat에서는 전쟁 패키징을 사용하면 실행 가능한 전쟁이 작동하고 표준 컨테이너(Tomcat에 한정되지 않고 Tomcat 포함)에도 전개할 수 있습니다.
Tomcat에서 하드 코딩된 파일 패턴 때문에 실행 가능한 jar가 작동하지 않습니다.
Jetty를 사용하면 전쟁 패키징을 사용할 수 있습니다. 즉, 실행 가능한 전쟁은 작동하며 표준 컨테이너에도 전개할 수 있습니다.
Undertow는 JSP를 지원하지 않습니다.
커스텀 error.jsp 페이지를 작성해도 에러 처리를 위한 기본 뷰가 덮어쓰지는 않습니다.대신 커스텀에러 페이지를 사용해야 합니다.
어떤 이유로든 전쟁 포장을 다룰 수 없다면 해킹이 있을 겁니다오래된 버전의 스프링 부츠를 위해 한 건 이 사람 덕분이야
한 가지 은 Tomcat을 하여 "Tomcat"을 추가하는 입니다.BOOT-INF/classestomcat © [ Resource Set] 리소스가됩니다.Tomcat은 ResourceSet을 사용합니다.예를 들어 서블릿 3.0 사양의 응용 프로그램 jar 패키지의 META-INF/리소스가 스캔되어 ResourceSet에 저장됩니다.
팻 jar, BOOT-INF/classes Resource Set, jar jar jar jar의의의의의 。 Lifecycle Listener Lifecycle Listener에서 할 수 .Lifecycle.CONFIGURE_START_EVENT이벤트, BOOT-INF/classes URL을 얻은 후 이 URL을 WebResourceSet에 추가합니다.완전한 예를 다음에 제시하겠습니다만, 다음과 같이 실시할 수 있습니다.
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));
}
});
}
}
};
}
}
다음으로 Lifecycle Listener를 다음과 같이 사용합니다.
import java.io.File;
import java.net.MalformedURLException;
import java.net.URL;
import org.apache.catalina.Context;
import org.apache.catalina.Lifecycle;

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) {

스프링 부트는 JSP와 함께 사용하면 매우 편리하며, 아래 구성만 하면 됩니다.
1 - tomcat-embad-interminal 의존관계
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>
2 - 다음 구성은 application.properties입니다.
spring.mvc.view.prefix: /
spring.mvc.view.suffix: .jsp
아직 의문이 남아 있습니다.다음 링크에서 확인해 주세요.
JSP를 jar 패키징과 함께 Spring Boot Application에서 성공적으로 사용하고 있으며, JSP 파일을 src/main/webapp/WEB-INF/JSP 디렉토리에 저장하고 응용 프로그램을 다음과 같이 구성합니다.
@Bean
public InternalResourceViewResolver viewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setViewClass(JstlView.class);
viewResolver.setPrefix("/WEB-INF/JSP/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
마이컨트롤러:
@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;
}
. . .
그리고 안녕.jsp는
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@page session="true"%>
<html>
<body>
<h1>Title : ${title}</h1>
<h1>${message}</h1>

안녕하세요 jsp를 jar에서 임베디드 Tomcat 폴더로 복사하는 방법을 알아봅니다.

나는 모든 가능한 해결책을 시도해 보았고 마침내 이것이 나를 도와주었다.
.xml에 합니다.

뷰 리졸버를 application.properties 파일에 추가합니다.
spring.mvc.view.prefix: /WEB-INF/jsp/
spring.mvc.view.suffix: .jsp
위의 코드가 완료되면 maven 명령어를 사용하여 프로젝트를 빌드한 후 표준 Java의 jar execution 명령을 사용하여 독립형 jar로 실행합니다.
cd <TO_YOUR_PROJECT_DIR>
mvn clean package spring-boot:repackage
java -jar target/<YOUR_PROJECT_CREATED_JAR>
어떤 이유로 SB2+에서도 이 기능이 필요한 경우 라이프 사이클 이벤트 방법을 약간 조정해야 했습니다.
@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 및 LocalDevelDetection.isDocker() 메서드:
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;
}
}
