结合实际项目分析pom.xml

1、build
Server:用来指定到哪个服务器，${}获取properties中的变量tomcat,然后调用settings.xml文件中配置的tomcat和用户名、密码（上一节）
url:用来指定发布到服务器的地址,h后面必须跟text
path:即部署到服务器的项目名,这里是webapps/MyWebAppDemo.war.访问路径http://192.168.234.9:8080/MyWebAppDemo
profile:
Server变量有三种配置方式：
a、
<properties> <warPackageName>MyWebAppDemo</warPackageName> <tomcat.deploy.server>localTestServer</tomcat.deploy.server>
<tomcat.deploy.serverUrl>http://localhost/manager/text</tomcat.deploy.serverUrl> </properties>
b、
<profiles> <profile> <id>deploy2production</id> <properties> <tomcat.deploy.server>productionServer</tomcat.deploy.server>
<tomcat.deploy.serverUrl>http://120.26.93.30:8080/manager/text</tomcat.deploy.serverUrl> </properties> </profile> </profiles>
c、
<plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <configuration> <port>8089</port> <path>/</path> <url>http://192.168.234.9:8080/manager/text</url> <username>admin</username> <password>admin</password> <update>true</update> </configuration> </plugin>
2、UTF-8编码问题
3、Spring框架冲突问题
因为既依赖dubbo框架，又依赖spring框架，导致报错（一般报NoSuchMethodError都是因为依赖冲突）
22-Oct-2016 01:17:46.438 信息 [http-nio-8080-exec-11] org.apache.catalina.core.ApplicationContext.log No Spring WebApplicationInitializer types detected on classpath
22-Oct-2016 01:17:46.550 严重 [http-nio-8080-exec-11] org.apache.catalina.core.StandardContext.listenerStart Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
java.lang.NoSuchMethodError: org.springframework.core.CollectionFactory.createConcurrentMapIfPossible(I)Ljava/util/Map;
解决方法：
<dependency> <groupId>com.alibaba</groupId> <artifactId>dubbo</artifactId> <version>2.5.3</version> <exclusions> <exclusion> <groupId>org.springframework</groupId> <artifactId>spring</artifactId> </exclusion> </exclusions> </dependency>
4、web.xml问题
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-war-plugin:2.2:war (default-war) on project test-maven-server-console: Error assembling WAR: webxml attribute is required (or pre-existing WEB-INF/web.xml if executing in update mode) -> [Help 1]
[ERROR]
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
[ERROR] Re-run Maven using the -X switch to enable full debug logging.
[ERROR]
[ERROR] For more information about the errors and possible solutions, please read the following articles:
解决方法：手动配置读取web.xml
<plugin> <artifactId>maven-war-plugin</artifactId> <configuration> <version>2.5</version> <webXml>src\main\webapp\WEB-INF\web.xml</webXml> </configuration> </plugin>
5、Maven clean导致引入jar文件没有编译的问题
[ERROR] /F:/stsProjects/test-maven-server-console/src/main/java/com/test/dubbo/controller/IndexController.java:[8,39] 程序包com.test.dubbo.registry.service不存在
[ERROR] /F:/stsProjects/test-maven-server-console/src/main/java/com/test/dubbo/controller/IndexController.java:[14,17] 找不到符号
符号: 类 TestRegistryService
位置: 类 com.test.dubbo.controller.IndexController
6、Maven默认使用jdk1.5的问题
7、web项目不存在src/main/webapp目录的问题
