eclipse maven 打war包的几种方式

第一种：利用pom.xml文件打包。

右键pom.xml文件，选择Debug as或Run as 都行。但需要选择Maven install  打包

 执行成功后，日志会打印出位置（看自己配置是否日志输出）。如果没有输出，在默认的C盘.m2文件夹中

第二种方式：右键项目。选择Debug as 或 Run as 。但是这个时候要选择 Debug configurations

先Browse Workspace  选择需要打包的项目 ，然后在Goals：中输入clean install  命令  Debug执行后，会在target目录下生成打的war包

第三种:直接右击项Export，然后选择WAR file　　( 推荐这种)

第四种；利用mvn package命令:(eclipse 中只用package就行 ，或者clean package  推荐这种)

mvn compile与mvn install、mvn deploy的区别

1. mvn compile，编译类文件
2. mvn install，包含mvn compile，mvn package，然后上传到本地仓库
3. mvn deploy,包含mvn install,然后，上传到私服

 　　打出war包之后直接部署到tomcat即可运行。类似于普通项目的部署。

 第五种:利用maven的插件

pom.xml中:

            <!-- tomcat插件 -->
            <plugin>
                <groupId>org.apache.tomcat.maven</groupId>
                <artifactId>tomcat7-maven-plugin</artifactId>
                <version>2.2</version>
                <configuration>
                    <port>80</port>
                    <path>/SSM</path>
                </configuration>
            </plugin>

run as :

　　tomcat7:exec-war

　　或者

　　tomcat7:exec-war-only

第六种:使用maven的war命令:

　　war:exploded    直接将项目打包成war包解压后的目录结构，类似于将war打包并解压

或者:    war:war    直接将项目打成war包。
