springboot 打包war及部署tomcat

打包war

1. pom文件修改

    <!--默认是jar，设置成war-->
    <packaging>war</packaging>

    <!--编译时使用内置tomcat，打包时不使用内置的tomcat-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
            <scope>provided</scope>
        </dependency>

    <!--添加打包插件-->
            <plugin>
                <artifactId>maven-war-plugin</artifactId>
                <version>2.6</version>
                <configuration>
                    <!--如果想在没有web.xml文件的情况下构建WAR，请设置为false。-->
                    <failOnMissingWebXml>false</failOnMissingWebXml>
                </configuration>
            </plugin>

2. 修改启动类

//1、添加注解
//2、继承SpringBootServletInitializer类重新configure方法
@SpringBootApplication
@ServletComponentScan
public class VenusProWebApplication extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return super.configure(builder);
    }

    public static void main(String[] args) {
        SpringApplication.run(VenusProWebApplication.class, args);
    }
}

3. maven工具打包即可

部署到tomcat

1. 直接将生成得war包放到webapps里面，这里主要tomcat得端口，不再使用yml文件里配置的端口号；

#这是无效的
server:
  port: 8080

2. 修改server.xml文件，端口、根目录等

<!-- host节点里添加，设置根目录，web是war名 -->
 <Context path="" docBase="web" reloadable="true" />

一台电脑运行多个tomcat

1. 再准备一个tomcat，可以是不同版本，也可以是直接复制已经存在的；
2. 下边几个地方修改端口号，只要不与其他tomcat端口冲突就行；

    <Server port="8055" shutdown="SHUTDOWN">

    <Connector port="8002" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

    <Connector port="8099" protocol="AJP/1.3" redirectPort="8443" />

3. 修改bin目录下，所有的bat文件，将CATALINA_HOME替换成CATALINA_HOME2，将CATALINA_BASE替换成CATALINA_BASE2；CATALINA_HOME是第一个tomcat的环境变量名称，CATALINA_HOME2是第二个tomcat的环境变量名称；设置环境变量添加到path中如：%CATALINA_HOME%\bin、%CATALINA_HOME2%\bin
4. 修改bin目录下的version.bat文件名为version2.bat
   5.打开命令输入version、version2显示两个tomcat的版本就ok了
