1:環境

eclipse indigo,

JDK1.6,

maven 3.2.1,

tomcat7.0.42

2:安裝eclipse maven插件 m2eclipse

第一種方法:從網上下載m2eclipse,這個網上有很多下載的地方。然後放到eclipse安裝目錄的plugins下。

第二種方法:打開eclipse->help->install new software。在work with後輸入:http://download.eclipse.org/technology/m2e/releases。如圖:

3:下載maven和tomcat

上apache官網下載maven:http://maven.apache.org/download.cgi。下載完成後解壓即可。

上apache官網下載tomcat:http://tomcat.apache.org/。

4:eclipse配置maven

window-》prefrences-》maven-》user setting。如圖

window-》prefrences-》maven-》installations。如圖

5:配置tomcat和maven

進入tomcat_home/conf/tomcat_users.xml:修改如下:

[html] view plain copy
print?
  1. <role rolename="admin-gui"/>
  2. <role rolename="admin-script"/>
  3. <role rolename="manager-gui"/>
  4. <role rolename="manager-script"/>
  5. <role rolename="manager-jmx"/>
  6. <role rolename="manager-status"/>
  7. <user username="admin" password="admin" roles="manager-gui,manager-script,manager-jmx,manager-status,admin-script,admin-gui"/>


進入maven_home/conf/settings.xml:修改如下:

[html] view plain copy print?
  1. <server>
  2. <id>tomcat</id>
  3. <username>admin</username>
  4. <password>admin</password>
  5. </server>


6:eclipse創建maven web項目

這個簡單,new-》other-》maven project-》next。這裏註意groupid選org.apache.maven.archetypes ,artifactid 選maven-archetype-webapp,然後next,輸入我們自己的groupid(com.test),artifactid(transition),然後finish,OK。如圖所示:

7:修改pom.xml

[html] view plain copy print?
  1. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  2. xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
  3. <modelVersion>4.0.0</modelVersion>
  4. <groupId>com.test</groupId>
  5. <artifactId>transition</artifactId>
  6. <packaging>war</packaging>
  7. <version>0.0.1</version>
  8. <name>transition Maven Webapp</name>
  9. <url>http://maven.apache.org</url>
  10. <repositories>
  11. <repository>
  12. <id>maven_remote_1</id>
  13. <url>http://mirrors.ibiblio.org/pub/mirrors/maven2/</url>
  14. </repository>
  15. </repositories>
  16. <dependencies>
  17. <dependency>
  18. <groupId>junit</groupId>
  19. <artifactId>junit</artifactId>
  20. <version>3.8.1</version>
  21. <scope>test</scope>
  22. </dependency>
  23. </dependencies>
  24. <build>
  25. <finalName>transition</finalName>
  26. <plugins>
  27. <plugin>
  28. <groupId>org.codehaus.mojo</groupId>
  29. <artifactId>tomcat-maven-plugin</artifactId>
  30. <configuration>
  31. <warFile>target/transition.war</warFile>
  32. <server>tomcat</server>
  33. <url>http://localhost:8080/manager/text</url>
  34. <path>/transition</path>
  35. </configuration>
  36. </plugin>
  37. </plugins>
  38. </build>
  39. </project>


8:運行maven項目

先進入tomcat目錄啟動tomcat,然後右鍵項目 run as-》run configrations:

Goals項輸入:package tomcat:redeploy

Maven Runtime選擇我們自己的maven。如圖:

然後點Run,控制臺顯示如下:

[plain] view plain copy print?
  1. [INFO] Processing war project
  2. [INFO] Copying webapp resources [E:\transition\src\main\webapp]
  3. [INFO] Webapp assembled in [3 msecs]
  4. [INFO] Building war: E:\transition\target\transition.war
  5. [INFO] WEB-INF\web.xml already added, skipping
  6. [INFO]
  7. [INFO] <<< tomcat-maven-plugin:1.1:redeploy (default-cli) @ transition <<<
  8. [INFO]
  9. [INFO] --- tomcat-maven-plugin:1.1:redeploy (default-cli) @ transition ---
  10. [INFO] Deploying war to http://localhost:8080/transition
  11. [INFO] OK - Undeployed application at context path /transition
  12. [INFO] OK - Deployed application at context path /transition
  13. [INFO] ------------------------------------------------------------------------
  14. [INFO] BUILD SUCCESS
  15. [INFO] ------------------------------------------------------------------------
  16. [INFO] Total time: 2.412 s
  17. [INFO] Finished at: 2014-03-13T11:43:42+08:00
  18. [INFO] Final Memory: 6M/15M
  19. [INFO] ------------------------------------------------------------------------

這裏省略很多控制臺輸出,出現BUILD SUCCESS 則說明部署成功,瀏覽器輸入:http://localhost:8080/transition/。顯示Hello world..

註意:這樣成功之後項目會直接打成war包,部署到tomcat下,每次build不需要重啟tomcat。這樣致命的缺點就是,不能調試。如果需要調試且在eclipse中啟動tomcat的話。會發現右鍵項目沒有run as server,有兩種方法解決:

第一種:這時需要把項目轉變成dynamic web module。右鍵項目-》properties-》project facets,然後右邊選中dynamic web module。之後就會出現run as server了.

第二種:右鍵項目,run/debug as configrations 如上第8步驟的圖。不過Goals中天上【tomcat:run】。然後run就OK了,註意這裏不需要提前啟動tomcat。
