This article mainly introduces "does SpringBoot 2.x support jsp deployment using jar". In daily operation, I believe many people have doubts about whether SpringBoot 2.x supports jsp deployment using jar. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the question of "does SpringBoot 2.x support jsp deployment using jar?" Next, please follow the editor to study!

1 pom.xml file modification

1 increase tomcat jsp dependency

Javax.servlet javax.servlet-api provided javax.servlet.jsp javax.servlet.jsp-api 2.3.1 javax.servlet jstl Org.springframework.boot spring-boot-starter-tomcat provided org.apache.tomcat.embed tomcat-embed-jasper 9.0.27 provided

2 modify resource packaging configuration

Src/main/webapp META-INF/resources * * / * * src/main/resources * / *

Second project catalogue

Add directory src/main/webapp, and jsp related files can be added to the directory

Add to application.properties

Spring.mvc.view.prefix=/WEB-INF/views/

Spring.mvc.view.suffix=.jsp

# support jsp debugger

Server.servlet.jsp.init-parameters.development=true

Third, modify the code

Add conversion configuration

StaticResourceConfigurer.java

Package com.vipkid.configuration;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;/** * Resource path conversion configuration * Add main class fat jar/exploded directory into tomcat ResourceSet. * * @ author zouqinghua * @ date 9:44:34 on October 30th 2019 * * / 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 ("/ BOOTHUBUINFHANG classeship /")) {/ / when run as fat jar locationStr = locationStr.substring (0, locationStr.length ()-"/ BOOTMUINFUBG classeship /" .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");}

Add listening class TomcatConfiguration.jsp

Package com.vipkid.configuration;import org.apache.catalina.Context;import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty;import org.springframework.boot.web.embedded.tomcat.ConfigurableTomcatWebServerFactory;import org.springframework.boot.web.embedded.tomcat.TomcatContextCustomizer;import org.springframework.boot.web.server.WebServerFactory;import org.springframework.boot.web.server.WebServerFactoryCustomizer;import org.springframework.boot.web.servlet.server.ConfigurableServletWebServerFactory;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.core.Ordered Import org.springframework.core.annotation.Order / * configure addLifecycleListener * @ author zouqinghua * @ date 9:45:28 on October 30, 2019 * * / @ Order (Ordered.HIGHEST_PRECEDENCE) @ Configuration@ConditionalOnProperty (name = "tomcat.staticResourceCustomizer.enabled" MatchIfMissing = true) public class TomcatConfiguration {/ * SpringBoot 1.x configuration @ return @ Bean public EmbeddedServletContainerCustomizer staticResourceCustomizer () {return new EmbeddedServletContainerCustomizer () {@ Override public void customize (ConfigurableEmbeddedServletContainer container) { If (container instanceof TomcatEmbeddedServletContainerFactory) {((TomcatEmbeddedServletContainerFactory) container) .addContextCustomizers (new TomcatContextCustomizer () {@ Override) Public void customize (Context context) {context.addLifecycleListener (new StaticResourceConfigurer (context)) );}} } * / * SpringBoot 2.x configuration * @ return * / @ Bean public WebServerFactoryCustomizer webServerFactoryCustomizerBean () {return new WebServerFactoryCustomizer () {@ Override public void customize (ConfigurableTomcatWebServerFactory factory) ) {factory.addContextCustomizers (new TomcatContextCustomizer () {@ Override public void customize (Context context) { Context.addLifecycleListener (new StaticResourceConfigurer (context)) });}} }}

Four codes

IndexController and

Src/main/webapp/WEB-INF/views/hello.jsp

Package com.smc.sys.web;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;@Controllerpublic class IndexController {@ RequestMapping ("/ hello") public String index () {System.out.println ("index = > >"); return "hello";} Hello World-${name}

Five, pack and start.

Mvn clean package-Dmaven.test.skip=true

Java-jar target/xxx.jar

Six visits

Http://localhost:8080/hello
