打开一个普通的Maven项目,打开pom.xml文件

 1  <?xml version="1.0" encoding="UTF-8"?>
 2  <project xmlns="http://maven.apache.org/POM/4.0.0"
 3           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 4           xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
 5      <modelVersion>4.0.0</modelVersion>
 6  ​
 7      <groupId>com.xing</groupId>
 8      <artifactId>javaweb-01-maven02</artifactId>
 9      <version>1.0-SNAPSHOT</version>
10  ​
11  ​
12      <properties>
13          <maven.compiler.source>8</maven.compiler.source>
14          <maven.compiler.target>8</maven.compiler.target>
15      </properties>
16  ​
17  </project>

导入jar包 （项目依赖dependencies）

 1  <?xml version="1.0" encoding="UTF-8"?>

 9      <version>1.0-SNAPSHOT</version>
10      <dependencies>
11          <!--Maven的高级之处在于，他会帮你导入这个jar包所依赖的其他jar-->

25      </properties>

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:

 约定大于配置   
 1  <!--buiLd中配置resources，来防止我们资源导出失败的问题，例java目录中只能导出java文件-->
 2  <build>
 3      <resources>
 4          <resource>
 5              <directory>src/main/resources</directory>
 6              <includes>
 7                  <include>**/*.properties</include>
 8                  <include>**/*.xml</include>
 9              </includes>
10              <filtering>false</filtering>
11          </resource>
12          <resource>
13              <directory>src/main/java</directory>
14              <includes>
15                  <include>**/*.properties</include>
16                  <include>**/*.xml</include>
17              </includes>
18              <filtering>false</filtering>
19          </resource>
20      </resources>
21  </build>
