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

http://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/luna/SR2/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。
