Maven自动部署war包到tomcat

步骤一： 

在tomcat安装目录下找到tomcat-users.xml文件。该文件路径为【tomcat安装根目录】 /conf/ 

修改文件内容，增加下列内容

 

1. <role rolename="manager"/>
2. <user username="tomcat" password="123456" roles="manager"/>

步骤二： 

在你的项目的pom.xml文件中，增加下列<plugin></plugin>中内容： 

 

1. <build>
2. 。。。。。
3. <plugins>
4. 。。。。。
5. <plugin>
6. <groupId>org.codehaus.mojo</groupId>
7. <artifactId>tomcat-maven-plugin</artifactId>
8. <configuration>
9. <url>http://localhost:8080/manager</url>
10. <username>tomcat</username>
11. <password>123456</password>
12. <path>/${finalName}</path>
13. </configuration>
14. </plugin>
15. 。。。
16. </plugins>
17. </build>

其中username和password就是tomcat中配置的username和password。 
当然在pom.xml的<properties>标签中，还需要定义war包的名字。假如只写成<path>/</path>，则部署的war包名字为ROOT.war。 
在pom.xml的<properties>标签中，定义war包名字内容如下： 

 

1. <properties>
2. <finalName>SSHMJ-FRANK</finalName>
3. </properties>

 然后运行maven命令：
mvn：tomcat:redeploy
或是直接在eclipse里面点 “run as”运行maven命令,如下图：


命令运行完成后，在tomcat的webapps目录下可见已经自动部署过去的war包，如下图：

 

开始运行自动部署命令时，一定要先启动tomcat。否则会报下列错误：

 

1. [INFO]
2. [INFO] --- tomcat-maven-plugin:1.0:redeploy (default-cli) @ SSHMJ-FRANK ---

最后得到的完整pom配置如下：
