spring boot默認web程序啟用tomcat內嵌容器tomcat，監聽8080端口,servletPath默認為?/?通過需要用到的就是端口、上下文路徑的修改，在spring boot中其修改方法及其簡單；

在資源文件中配置：

?

server.port=9090 server.contextPath=/lkl

?

啟動spring boot

2015-10-04 00:06:55.768 INFO 609 --- [ main] o.s.w.s.handler.SimpleUrlHandlerMapping : Mapped URL path [/**/favicon.ico] onto handler of type [class org.springframework.web.servlet.resource.ResourceHttpRequestHandler] 2015-10-04 00:06:55.844 INFO 609 --- [ main] o.s.j.e.a.AnnotationMBeanExporter : Registering beans for JMX exposure on startup 2015-10-04 00:06:55.928 INFO 609 --- [ main] s.b.c.e.t.TomcatEmbeddedServletContainer : Tomcat started on port(s): 9090 (http) 2015-10-04 00:06:55.930 INFO 609 --- [ main] com.lkl.springboot.Application : Started Application in 3.906 seconds (JVM running for 4.184)

可以看出其監聽端口9090，執行?
http://localhost:9090/lkl/springboot/liaokailin?成功訪問

自定義tomcat

在實際的項目中簡單的配置tomcat端口肯定無法滿足大家的需求，因此需要自定義tomcat配置信息來靈活的控制tomcat。

以定義默認編碼為例

package com.lkl.springboot.container.tomcat;import org.springframework.boot.context.embedded.EmbeddedServletContainerFactory; import org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedServletContainerFactory; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration;/*** tomcat 配置* @author liaokailin* @version $Id: TomcatConfig.java, v 0.1 2015年10月4日 上午12:11:47 liaokailin Exp $*/ @Configuration public class TomcatConfig {@Beanpublic EmbeddedServletContainerFactory servletContainer() {TomcatEmbeddedServletContainerFactory tomcat = new TomcatEmbeddedServletContainerFactory();tomcat.setUriEncoding("UTF-8");return tomcat;}}

?

構建EmbeddedServletContainerFactory的bean，獲取到TomcatEmbeddedServletContainerFactory實例以后可以對tomcat進行設置，例如這里設置編碼為UTF-8

SSL配置

生成證書

keytool -genkey -alias springboot -keyalg RSA -keystore /Users/liaokailin/software/ca1/keystore 設置密碼123456

tomcat中驗證證書是否正確

修改tomcat/conf/server.xml文件

<Connector protocol="org.apache.coyote.http11.Http11NioProtocol"port="8443" maxThreads="200"scheme="https" secure="true" SSLEnabled="true"keystoreFile="/Users/liaokailin/software/ca1/keystore" keystorePass="123456"clientAuth="false" sslProtocol="TLS"/>

啟動tomcat ，訪問?http://localhost:8443

spring boot 內嵌tomcat ssl

配置資源文件

server.port=8443 server.ssl.enabled=true server.ssl.keyAlias=springboot server.ssl.keyPassword=123456 server.ssl.keyStore=/Users/liaokailin/software/ca1/keystore

• server.ssl.enabled?啟動tomcat ssl配置
• server.ssl.keyAlias?別名
• server.ssl.keyPassword?密碼
• server.ssl.keyStore?位置

啟動?spring boot

訪問https://localhost:8443/springboot/helloworld

多端口監聽配置

前面啟動ssl后只能走https,不能通過http進行訪問，如果要監聽多端口，可采用編碼形式實現。

1.注銷前面ssl配置，設置配置?server.port=9090

2.修改TomcatConfig.java

?

package com.lkl.springboot.container.tomcat;import java.io.File;import org.apache.catalina.connector.Connector; import org.apache.coyote.http11.Http11NioProtocol; import org.springframework.boot.context.embedded.EmbeddedServletContainerFactory; import org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedServletContainerFactory; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration;/*** tomcat 配置* @author liaokailin* @version $Id: TomcatConfig.java, v 0.1 2015年10月4日 上午12:11:47 liaokailin Exp $*/ @Configuration public class TomcatConfig {@Beanpublic EmbeddedServletContainerFactory servletContainer() {TomcatEmbeddedServletContainerFactory tomcat = new TomcatEmbeddedServletContainerFactory();tomcat.setUriEncoding("UTF-8");tomcat.addAdditionalTomcatConnectors(createSslConnector());return tomcat;}private Connector createSslConnector() {Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");Http11NioProtocol protocol = (Http11NioProtocol) connector.getProtocolHandler();try {File truststore = new File("/Users/liaokailin/software/ca1/keystore");connector.setScheme("https");protocol.setSSLEnabled(true);connector.setSecure(true);connector.setPort(8443);protocol.setKeystoreFile(truststore.getAbsolutePath());protocol.setKeystorePass("123456");protocol.setKeyAlias("springboot");return connector;} catch (Exception ex) {throw new IllegalStateException("cant access keystore: [" + "keystore" + "] ", ex);}} }

通過addAdditionalTomcatConnectors方法添加多個監聽連接;此時可以通過http 9090端口，https 8443端口。
