1.打开idea
2.创建一个Maven项目
3.观察本地仓库里面多了些什么?
4.IDEA中配置maven
5.新建一个普通的maven项目
我们来看一下刚才用模板创建的项目,webapp这些只有在web项目才会有的:
6.idea标记文件夹功能
第二种方式:
7.在idea中配置tomcat
把项目生成的war包,发布到tomcat。
启动tomcat
访问页面:
idea的maven右侧菜单:
8.pom.xml文件
<?xml version="1.0" encoding="UTF-8"?> <!-- Maven版本和头文件 --> <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/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <!-- 这里就是我们刚才配置的GAV --> <groupId>com.allen</groupId> <artifactId>javaweb-01-maven</artifactId> <version>1.0-SNAPSHOT</version> <!-- package:项目打包方式 jar:Java应用 war:javaweb应用 --> <packaging>war</packaging> <!-- 配置 --> <properties> <!-- 项目默认构建编码 --> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <!-- 编码版本 --> <maven.compiler.source>1.7</maven.compiler.source> <maven.compiler.target>1.7</maven.compiler.target> </properties> <!-- 项目依赖 --> <dependencies> <!-- 具体依赖的jar包配置文件 --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <scope>test</scope> </dependency> </dependencies> <!-- 项目构建用的 --> <build> <finalName>javaweb-01-maven</finalName> <pluginManagement><!-- lock down plugins versions to avoid using Maven defaults (may be moved to parent pom) --> <plugins> <plugin> <artifactId>maven-clean-plugin</artifactId> <version>3.1.0</version> </plugin> <!-- see http://maven.apache.org/ref/current/maven-core/default-bindings.html#Plugin_bindings_for_war_packaging --> <plugin> <artifactId>maven-resources-plugin</artifactId> <version>3.0.2</version> </plugin> <plugin> <artifactId>maven-compiler-plugin</artifactId> <version>3.8.0</version> </plugin> <plugin> <artifactId>maven-surefire-plugin</artifactId> <version>2.22.1</version> </plugin> <plugin> <artifactId>maven-war-plugin</artifactId> <version>3.2.2</version> </plugin> <plugin> <artifactId>maven-install-plugin</artifactId> <version>2.5.2</version> </plugin> <plugin> <artifactId>maven-deploy-plugin</artifactId> <version>2.8.2</version> </plugin> </plugins> </pluginManagement> </build> </project>
maven由于他的约定大于配置,我们之后可以能遇到我们写的配置文件,无法被导出或者生效的问题,解决方案:
<!-- 在build中配置resources,来防止我们资源导出失败的问题 --> <build> <resources> <resource> <directory>src/main/resources</directory> <excludes> <exclude>**/*.properties</exclude> <exclude>**/*.xml</exclude> </excludes> <filtering>false</filtering> </resource> <resource> <directory>src/main/java</directory> <includes> <include>**/*.properties</include> <include>**/*.xml</include> </includes> <filtering>false</filtering> </resource> </resources> </build>
9.Maven远程仓库
选择版本:
maven依赖:
