本文介绍了spring boot实战之内嵌容器tomcat配置，分享给大家，具体如下：
默认容器
spring boot默认web程序启用tomcat内嵌容器tomcat，监听8080端口,servletPath默认为 / 通过需要用到的就是端口、上下文路径的修改，在spring boot中其修改方法及其简单；
在资源文件中配置：
server.port=9090 server.contextPath=/lkl
启动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)
可以看出其监听端口9090，执行 http://localhost:9090/lkl/springboot/liaokailin 成功访问
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。
以定义默认编码为例
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 {
@Bean
public EmbeddedServletContainerFactory servletContainer() {
TomcatEmbeddedServletContainerFactory tomcat = new TomcatEmbeddedServletContainerFactory();
tomcat.setUriEncoding("UTF-8");
return tomcat;
}
}
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/liaokailin/software/ca1/keystore 设置密码123456
tomcat中验证证书是否正确
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"/>
启动tomcat ，访问 http://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/liaokailin/software/ca1/keystore
启动 spring boot
访问https://localhost:8443/springboot/helloworld
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=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 {
@Bean
public 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);
}
}
}
通过addAdditionalTomcatConnectors方法添加多个监听连接;此时可以通过http 9090端口，https 8443端口。
