Maven构建Web项目

来源：互联网发布：mac 弱网络工具编辑：程序博客网时间：2024/05/01 10:54

开发环境: eclipse

开始构建

新建maven项目

archetypes选择webapp

刚建好项目时jsp文件报错,因为没有相应API支持,只要引入相应依赖即可

创建完整目录结构如下(保证main和test目录下都有各自的java与resources目录)

确保项目输出文件路径正确: Build Path --> Configure Build Path(查看四个Output folder是否都是项目/target/classes)

右击项目 Properties --> Project Facets 选中Dynamic Web Module, 将项目转换成web项目

更改部署配置 Properties -->Deployment Assembly ,将test部分目录移除

使用jetty容器插件装载web,首先对pom.xml进行插件添加

通过jetty:run指令进行Maven Build时报错

[ERROR] Failed to execute goal org.eclipse.jetty:jetty-maven-plugin:9.4.8.v20171121:run (default-cli) on project mavendemo: Failure: Address already in use: bind -> [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:[ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/MojoExecutionException

机智的我重启了下eclipse就OK了

[INFO] Scavenging every 660000ms[INFO] Started o.e.j.m.p.JettyWebAppContext@7cf162bc{/,file:///D:/eclipse-workspace/mavendemo/mavendemo/src/main/webapp/,AVAILABLE}{file:///D:/eclipse-workspace/mavendemo/mavendemo/src/main/webapp/}[INFO] Started ServerConnector@249e0271{HTTP/1.1,[http/1.1]}{0.0.0.0:8080}[INFO] Started @4952ms[INFO] Started Jetty Server

接下来配置自动启动服务功能,在打包项目时,自动调用run启动jetty插件

                 <plugins><plugin><groupId>org.eclipse.jetty</groupId><artifactId>jetty-maven-plugin</artifactId><version>9.4.8.v20171121</version><executions><execution><!-- 在打包成功后使用jetty:run来运行jetty服务 --><phase>package</phase><goals><goal>run</goal></goals></execution></executions>  </plugin></plugins>

以上配置,在调用package命令时会启动jetty

使用Tomcat作为web容器时,只需将 jetty 插件的定位换成 Tomcat 插件的定位即可

访问方式跟jetty有点不一样,jetty不需要填入项目名

----------------------------------------------------

发现一件尴尬的事情:

直接通过Tomcat:run运行,访问项目报错

最后附上我的pom

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.joey.mavendemo</groupId><artifactId>mavendemo</artifactId><packaging>war</packaging><version>0.0.1-SNAPSHOT</version><name>mavendemo Maven Webapp</name><url>http://maven.apache.org</url><dependencies><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>3.8.1</version><scope>test</scope></dependency><dependency><groupId>javax.servlet</groupId><artifactId>javax.servlet-api</artifactId><version>4.0.0</version><scope>provided</scope></dependency></dependencies><build><finalName>mavendemo</finalName><plugins><plugin><groupId>org.apache.tomcat.maven</groupId>                    <artifactId>tomcat7-maven-plugin</artifactId>                    <version>2.2</version><executions><execution><!-- 在打包成功后使用tomcat:run来运行tomcat服务 --><phase>package</phase><goals><goal>run</goal></goals></execution></executions>  </plugin></plugins></build></project>
