[开发背景]

tomcat启动之后占用三个端口。我对此非常不理解，我决定在tomcat基础之上,开发一个新的tomcat,仅仅占用一个端口。

bill-tomcat开发

创建工程

pom.xml中添加依赖

<properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><jdk.version>1.6</jdk.version>
</properties>
<dependencies><dependency><groupId>org.apache.tomcat.maven</groupId><artifactId>tomcat7-maven-plugin</artifactId><version>2.2</version></dependency><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.12</version><scope>test</scope></dependency>
</dependencies>
<build><plugins><plugin><!-- java编译插件 --><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><version>3.2</version><configuration><source>${jdk.version}</source><target>${jdk.version}</target><encoding>UTF-8</encoding></configuration></plugin></plugins>
</build>

在src/main/resources创建webapps目录

在src/main/resources创建tomcat.properties

内容如下

tomcat.port=8080

进行编码

}

package com.uairobot.bill.tomcat;public class Constants {public static final String tomcatPort = "tomcat.port";
}

}

执行TomcatServer就可以启动项目

bill-tomcat打包

打包概述和启动命令

what is 打包

打包:将程序打包成tar.gz文件,可以放到服务器上运行

 

[总体概述]

将依赖包和项目包放到lib目录下

将配置文件放到config目录下载

将webapps,放到webapps目录下

 

[启动命令]

因为要在classpath下载寻找webapps所以需要将当前目录,config目录和lib目录添加到到classpath下

在linux上前台启动

java -Xverify:none -cp .:./config:./lib/*: com.uairobot.bill.tomcat.TomcatServer

maven-jar-plugin

maven-jar-plugin排除配置文件和webapps目录不添加到jar包中

<plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-jar-plugin</artifactId><version>2.6</version><configuration><excludes><exclude>*.txt</exclude><exclude>*.xml</exclude><exclude>*.properties</exclude><exclude>webapps</exclude><exclude>webapps/*</exclude><exclude>sql</exclude><exclude>sql/*</exclude></excludes></configuration>
</plugin>

</assembly>

启动脚本

src\main\bin\bill-tomcat.sh内容如下

打包

使用clean package -DskipTests在Eclipse会出现中会出现MANIFEST.MF (系统找不到指定的路径。)所以执行install

clean install -DskipTests

打包完成后生成文件名bill-tomcat-1.0-release.tar.gz,文件大小是13.3 MB

bill-tomcat安装

[下载]

.0

下载bill-tomcat-1.0-release.tar.gz

[bill-tomcat安装]

mkdir /opt/package/bill-tomcat
cd /opt/package/bill-tomcat
#上传bill-tomcat-1.0-release.tar.gz到此目录下
tar -xf bill-tomcat-1.0-release.tar.gz -C /usr/local/
cd /opt/package/bill-tomcat
#在linux上后台启动
./bill-tomcat.sh start

在linux上前台启动

cd /opt/package/bill-tomcat
/usr/java/jdk1.8.0_211/bin/java -Xverify:none -cp ./config:./lib/*: com.uairobot.bill.tomcat.TomcatServer

[向bill-tomcat安装部署项目]

#进入webapps目录
cd /usr/local/bill-tomcat-1.0/webapps
#本tomcat不会自动解压war包,需要手动下载war并解压到此目录下
wget .0.war
mkdir bill-websocket-web-chat
unzip bill-websocket-web-chat-1.0.war -d  bill-websocket-web-chat
#重启让部署的项目生效
/usr/local/bill-tomcat-1.0/bill-tomcat.sh restart

#访问

http://192.168.78.131:8080/bill-websocket-web-chat/

基于bill-tomcat进行开发

其实很简单,在pom.xml中添加omcat7-maven-plugin的依赖即可,这样我们就不需要向项目中添加重复的依赖了

<dependency><groupId>org.apache.tomcat.maven</groupId><artifactId>tomcat7-maven-plugin</artifactId><version>2.2</version><scope>provided</scope>
</dependency>
