使用Tomcat部署Springboot项目

项目背景

项目需要将war包部署到Tomat,然后在网络上踩了许多坑，记录一下

(12条消息) SpringBoot War包形式部署到外部Tomcat_zhuyu19911016520-CSDN博客_springboot打war包部署到tomcat

(12条消息) Win10环境Tomcat安装及环境变量配置教程_LL_Leung的博客-CSDN博客_tomcat windows10

1.配置window下 tomcat环境

• 配置jdk环境
• CATALINA_HOME： 路放置tomcat文件夹的完整路径。D:\apache-tomcat-8.5.73
• 在path后配置：%CATALINA_HOME%\lib 、%CATALINA_HOME%\bin

2.在spring boot中打包

public class Application extends SpringBootServletInitializer  {


    public static void main(String[] args) {
        SpringApplication app=new SpringApplication(Application.class);
        ApplicationContext context = app.run(args);
        String serverPort=context.getEnvironment().getProperty("server.port");
        log.info("start at http:localhost:"+serverPort);
    }


    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(Application.class);
    }

}

3.pom引入

<packaging>war</packaging>

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <exclusions>
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<!--提供阻塞和非阻塞机制-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-undertow</artifactId>
    <scope>provided</scope>
</dependency>

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.1.0</version>
    <scope>provided</scope>
</dependency>

<build>
    <finalName>SE</finalName>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
</build>

注意：如果希望使用外置tomcat需要将原来的tomcat排除，如果希望在正常的项目中使用，需要添加spring-boot-starter-undertow或者tomcat，其中 provided代表在开发环境下存在，打包不包含； javax.servlet-api不引用将无法打包；SE用于确定包的名字；war打包为war包，默认为jar

3.在tomcat中配置

• 如果乱码，将conf/logging.properties 改为java.util.logging.ConsoleHandler.encoding = GBK
• 在server.xml配置

<Service name="testWar">  
     <Connector port="8088"    maxHttpHeaderSize="8192"  maxThreads="150" minSpareThreads="25" maxSpareThreads="75" enableLookups="true" redirectPort="8443" acceptCount="100" connectionTimeout="20000" disableUploadTimeout="true"  URIEncoding="utf-8"/>   
     <Engine name="hnswzy" defaultHost="localhost">
     <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/>
     <Host name="localhost" unpackWARs="true" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false"> 
         <Context path="" reloadable="true" docBase="F:\project\crash\SEquipment\SE_Video_DATA\target\SE">
         </Context>
     </Host>
     </Engine>
     </Service>

其中docBase="F:\project\crash\SEquipment\SE_Video_DATA\target\SE"为包的绝对路径（在F:\project\crash\SEquipment\SE_Video_DATA\target\SE.war存在该文件）开启两个服务

• 或者在原service直接修改host标签下添加

<Context path="" reloadable="true" docBase="F:\project\crash\SEquipment\SE_Video_DATA\target\SE">
         </Context>
