本文档详细介绍了如何将一个基于Idea、Springboot和Maven的Java应用打包成War文件，并在Tomcat服务器上进行部署。首先，需要在Application启动类中继承SpringBootServletInitializer并重写configure方法。接着，配置pom.xml，设置packaging为War，并指定War包名称。然后，确保应用目录结构符合Tomcat要求。完成这些步骤后，使用Maven的clean和package命令生成War包。最后，将War包放入Tomcat的webapps目录下，并在Tomcat的server.xml中配置Context。启动Tomcat后，可以通过浏览器访问应用。

Idea+Springbot+Maven打包为War包并在Tomcat运行

1、配置启动程序

Application启动类需要继承SpringBootServletInitializer 并重写configure 方法

package startApp;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication
@ComponentScan(basePackages = {"controllers"})
public class DlbApplication extends SpringBootServletInitializer {
    public static void main(String[] args){
        SpringApplication.run(DlbApplication.class,args);
    }
    @Override
    protected SpringApplicationBuilder configure (SpringApplicationBuilder builder){
        return builder.sources(DlbApplication.class);
    }
}

2、pom.xml文件配置

注意配置<packaging>为War，FileName标签可以为War包命名

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>WW</groupId>
    <artifactId>DLB</artifactId>
    <version>1.0-SNAPSHOT</version>
    <dependencies>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.13</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <version>2.2.6.RELEASE</version>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <version>2.2.6.RELEASE</version>
        </dependency>
    </dependencies>

    <packaging>war</packaging>
    <build>
        <finalName>DlbWar</finalName>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <version>2.2.6.RELEASE</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>
</project>

3、注意和Tomcat启动需要的结构一致

xml中的文件内容为

<xml version="1.0" encoding="utf-8" />

4、打包成war包->clean和packaging

生成的war包在target文件夹中

6、war包部署在tomcat中

war包复制到tomcat中的webapps中

配置conf->server.xml，在<host>标签中添加一行内容

docbase为war包的名称

其他的配置不用管

server.xml文件全部内容

<?xml version="1.0" encoding="UTF-8"?>


<Server port="8005" shutdown="SHUTDOWN">
<Listener className="org.apache.catalina.startup.VersionLoggerListener" />


<Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />

<Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />
<Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
<Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />


<GlobalNamingResources>

<Resource name="UserDatabase" auth="Container"
type="org.apache.catalina.UserDatabase"
description="User database that can be updated and saved"
factory="org.apache.catalina.users.MemoryUserDatabaseFactory"

</GlobalNamingResources>


<Service name="Catalina">





<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />













<Engine name="Catalina" defaultHost="localhost">





<Realm className="org.apache.catalina.realm.LockOutRealm">

<Realm className="org.apache.catalina.realm.UserDatabaseRealm"
resourceName="UserDatabase"/>
</Realm>

<Host name="localhost" appBase="webapps"
unpackWARs="true" autoDeploy="true">

<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
prefix="localhost_access_log" suffix=".txt"
pattern="%h %l %u %t "%r" %s %b" />

</Host>
</Engine>
</Service>
</Server>
