spring boot实战(第七篇)内嵌容器tomcat配置

原文：https://blog.csdn.net/liaokailin/article/details/48948093

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

server.ssl.enabled 启动tomcat ssl配置
server.ssl.keyAlias 别名
server.ssl.keyPassword 密码
server.ssl.keyStore 位置

启动 spring boot

启动spring boot

访问 https://localhost:8443/springboot/helloworld

访问https

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。
