Java Web Application开发
1 下载需要的软件
使用的软件并没有采用最新的版本,只是采用了次新版本。
1.1 下载Eclipse的jee版本
eclipse-jee-luna-SR2-macosx-cocoa-x86_64.tar.gz
1.2 下载JDK 7.0
jdk-7u79-macosx-x64.dmg
http://www.oracle.com/technetwork/cn/java/javase/downloads/jdk7-downloads-1880260.html
1.3 下载Tomcat 7.0
apache-tomcat-7.0.63.zip
http://tomcat.apache.org/download-70.cgi
1.4 下载tomcatPluginV331.zip
http://www.eclipsetotale.com/tomcatPlugin.html
2 安装开发环境
2.1 安装JDK
双击 jdk-7u79-macosx-x64.dmg,然后step by step。
2.2 安装Tomcat
Ref[3.1]
A: 解压apache-tomcat-7.0.63.zip 到目录 ~/Downloads/apache-tomcat-7.0.63
B: 运行以下命令
sudo mkdir -p /usr/local
sudo mv ~/Downloads/apache-tomcat-7.0.63 /usr/local
C: 运行以下命令
sudo rm -f /Library/Tomcat
sudo ln -s /usr/local/apache-tomcat-7.0.63 /Library/Tomcat
D: 运行以下命令
sudo chown -R <your_username> /Library/Tomcat
sudo chmod u+x /Library/Tomcat/bin/*.sh
E: 运行以下命令,启动和关闭Tomcat Server
/Library/Tomcat/bin/startup.sh
/Library/Tomcat/bin/shutdown.sh
2.3 安装Eclipse
将eclipse-jee-luna-SR2-macosx-cocoa-x86_64.tar.gz解压到 ~/your-dev-tools-path/eclipse-jee-luan
2.4 安装tomcatPluginV331.zip (Sysdeo Eclipse Tomcat Launcher plugin)
解压tomcatPluginV331.zip得到com.sysdeo.eclipse.tomcat_3.3.1.jar,将该jar包复制到 ~/your-dev-tools-path/eclipse-jee-luan/dropins/ 目录下。
2.5 启动Eclipse,此时在其工具栏上会出现。 Figure-1: Tomcat Icon in Tool Bar
2.6 配置Eclipse,首先检查JRE是否设置好,如Figure-2:JRE for Eclipse
2.7 Web应用服务器的配置
Figure-3: Server Runtime Environments
2.8 为Tomcat进行配置
Figure-4: Tomcat Configuration
Q: Context declaration mode: Server.xml 和 Context files的区别是什么呢?
2.9 到此整个配置过程结束
点击工具条(Figure-1)中Tomcat Logo启动Tomcat Server。
在Eclpise中的Console中,会有下输出, Figure-5 Output in Console
在浏览器中输出:http://localhost:8080/, 来验证Tomcat Server是否已被正确启动。
3 创建Web Application Project
3.1 Tomcat Project
Ref[5]
Eclipse中,File->New->Project...->Java->Tomcat Project, 然后点击Next, Figure-6: New Tomcat Project
Demo:
3.2 Dynamic Web Project
4 导入Web Application Project
File->Import...->General->Existing Project into Workspace
Figure-7: Import Existing Project into Workspace
5. 如何调试 Web Application Project
Ref[7]
6. 打包部署Web Application Project
6.1 在Eclipse中打包Web Application Project 为war文件
Ref[10]
关于war文件的说明:
"In Java enterprise development, WAR (Web ARchive) is the standard container file format for
packaging Java EE applications as a single, deployable unit which can be deployed on Java EE-compliant
application servers like Tomcat, JBoss, Glassfish..." Ref[10]
6.2 部署war文件到tomcat server
Ref[12]
A): 将war文件拷贝到$CATALINA_HOME\webapps目录下。
B): 如果tomcat server在运行中, 将tomcat停下来。删除由原来war解压得到的目录。
C): 启动tomcat server。
7. 用配置项来替代Web Application中hardcode的路径等
Ref[11]
用配置文件中配置项来替代Web Application中JSP/Servlet中hardcode的路径等信息。
