spring boot默认web程序启用tomcat内嵌容器tomcat,监听8080端口,servletPath默认为 /
。需要用到的就是端口、上下文路径的修改,在spring boot中其修改方法极其简单,实例如下:
server.port=8088 server.context-path=/test
启动程序,日志如下:
2018-03-08 19:57:58.824 INFO 12046 --- [ main] s.b.c.e.t.TomcatEmbeddedServletContainer : Tomcat started on port(s): 8088 (http)
可以看出其监听端口8088
自定义tomcat
在实际的项目中简单的配置tomcat端口肯定无法满足大家的需求,因此需要自定义tomcat配置信息来灵活的控制tomcat。下面的实例定义了tomcat的默认编码格式
package com.ysl.conf;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;import java.nio.charset.Charset;/*** tomcat配置*/ @Configuration public class TomcatConfig {@Beanpublic EmbeddedServletContainerFactory servletContainer(){TomcatEmbeddedServletContainerFactory factory = new TomcatEmbeddedServletContainerFactory();factory.setUriEncoding(Charset.forName("UTF-8"));return factory;} }
构建EmbeddedServletContainerFactory
的bean,获取到TomcatEmbeddedServletContainerFactory
实例以后可以对tomcat进行设置,例如这里设置编码为UTF-8
SSL配置
生成证书
keytool -genkey -alias springboot -keyalg RSA -keystore /Users/ysl/software/ca1/keystore
设置密码123456
修改tomcat的server.xml,验证证书是否正确
<Connectorprotocol="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"/>
启动tomcat,访问https://localhost:8443
spring boot 内嵌tomcat ssl
配置资源文件:
server.port=8443 server.ssl.enabled=true server.ssl.keyAlias=springboot server.ssl.keyPassword=123456 server.ssl.keyStore=/Users/ysl/software/ca1/keystore
多端口监听配置
前面启动ssl后只能走https,不能通过http进行访问,如果要监听多端口,可采用编码形式实现。
1.注销前面ssl配置,设置配置 server.port=8088
2.修改TomcatConfig.java
package com.ysl.conf;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;import java.io.File; import java.nio.charset.Charset;/*** tomcat配置*/ @Configuration public class TomcatConfig {@Beanpublic EmbeddedServletContainerFactory servletContainer(){TomcatEmbeddedServletContainerFactory factory = new TomcatEmbeddedServletContainerFactory();factory.setUriEncoding(Charset.forName("UTF-8"));factory.addAdditionalTomcatConnectors(createSslConnector());return factory;}private Connector createSslConnector() {Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");Http11NioProtocol protocol = (Http11NioProtocol) connector.getProtocolHandler();try {File truststore = new File("/Users/ysl/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);}} }
通过addAdditionalTomcatConnectors
方法添加多个监听连接;此时可以通过http 8088端口,https 8443端口。
