​1.3 ​ssh工程构建​​

​1.3.1 ​创建maven web工程​​

​根据需求，SSH整合需要创建web工程：​maven-ssh​工程。​

Web-第二十六天 Maven学习二【悟空教程】_spring_04​ ​

​1.3.2 ​pom.xml​​

​在pom.xml添加工程依赖：​

​（本工程为ssh整合工程，依赖struts2.3.24、 spring4.2.4、hibernate5.0.7等），如下：​

​执行tomcat:run命令maven默认使用org.codehaus.mojo. tomcat-maven-plugin插件​

Web-第二十六天 Maven学习二【悟空教程】_spring_05

​访问：http://localhost:8080/工程名/...​

​修改访问路径及端口：​

​<plugin>​

​                <groupId>org.codehaus.mojo</groupId>​

​                <artifactId>tomcat-maven-plugin</artifactId>​

​                <version>1.1</version>​

​<!-- 指定端口 -->​

​<port>8088</port>​

​<!-- 指定Context Path​

​如果不指定则Context Path为build标签中finalName指定的名称，若没指定，则为artifactId的值​

​-->​

​<path>/ssh</path>​

​</build>​


​执行如下命令： ​

​mvn tomcat6:run​

​访问：http://localhost:8088/ssh​


​1.3.9.2 ​tomcat7:run​​（​​推荐使用​​）​​ ​​

​org.apache.tomcat.maven提供了tomcat7插件，在pom.xml中配置：​

​<!-- 配置Tomcat7插件 -->​

​<plugin>​

​<groupId>org.apache.tomcat.maven</groupId>​

​<artifactId>tomcat7-maven-plugin</artifactId>​

​<version>2.2</version>​

​<configuration>​

​<!-- 指定端口 -->​

​<port>8081</port>​

​<!-- 请求路径 -->​

​<path>/</path>​

​</configuration>​

​</plugin>​


​执行命令： ​

​mvn tomcat7:run​

​访问：http://localhost:8081/​


​1.3.9.3 ​端口占用​​

​重新执行tomcat:run命令重启工程，重启之前需手动停止 tomcat，否则报下边的错误：​

​Caused by: java.net.BindException: Address already in use: JVM_Bind​


​1.3.9.4 ​断点调试​​

​maven工程断点调试必须采用“Debug As”方式启动，并且需要引入源码才可源码跟踪：​

2 分模块构建工程

​2.1 ​需求​​

​2.1.1 ​需求描述​​

​将maven-ssh工程，按照工程的三层结构进行拆分，拆分为ssh-domain、ssh-dao、ssh-service、ssh-web工程。​


​2.1.2 ​需求分析​​

​1.拆分之后的工程，可以分别被打成jar包或者war包，这样可以提升domain、dao和Service层的可重用性。​

​2.拆分之后，有很多相同的pom文件配置，此时为了解决可重复性，需要提取出一个父工程：maven-parent​

​3.拆分之后的工程，在运行时，需要合并到一起再进行启动，此时，需要将他们聚合到一起，而maven提供聚合工程来实现此功能。​

​2.1.3 ​理解继承和聚合​​

​通常继承和聚合同时使用。 ​

  • ​何为聚合？ ​

​项目开发通常是分组分模块开发，每个模块开发完成需要将模块聚合在一起运行​

  • ​何为继承？ ​

​继承为了消除重复，我们把很多相同的配置提取出来，子模块继承父模块。 ​

​​注意：父工程和聚合工程的打包方式都必须为POM方式​。​


​2.1.4 ​拆分后的工程结构​​

​Maven-parent（锁定版本，pom）​

​|--ssh-domain（jar）​

​|--ssh-dao(jar)​

​|--ssh-service(jar)​

​|--ssh-web(war)​


​2.2 ​案例实现​​
