Eclipse配置maven项目

1.首先创建maven项目

1.1右键new创建，点击maven project

1.2将Create a simple project(skip archetype selection)勾上，创建一个简单的工程，点击next

1.3然后依次填写项目包名，项目名称，版本默认就可以，打包方式选择war，然后点击finish

2.处理报错

2.1 创建完成后如下图pom.xml文件报错

 

 是因为缺少web.xml文件，如下图

 

2.2创建web.xml文件，创建完成后，查看一下web.xml的版本号

2.3 修改web.xml版本号，和jdk

 

将之前创建的web.xml删除在重复创建一个web.xml文件

 

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 

xmlns="http://xmlns.jcp.org/xml/ns/javaee" 

xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee

http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1">

 

现在web.xml版本就变成了3.1

 

2..4现在又有个问题当我更新项目时又变成怎么解决这个问题呢

在pom.xml中配置

指定jdk和设置编码

<properties>

<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

<maven.compiler.encoding>UTF-8</maven.compiler.encoding>

</properties>

 

<build>

<plugins>

<!-- 指定jdk，防止update project -->

<plugin>

<groupId>org.apache.maven.plugins</groupId>

<artifactId>maven-compiler-plugin</artifactId>

<configuration>

<source>1.8</source>

<target>1.8</target>

<!-- 项目编码 -->

<encoding>UTF-8</encoding>

</configuration>

</plugin>

</plugins>

</build>

这样在我们跟新项目时就不会改jdk的版本了

2.5导入jar包，配置文件

 

更新项目

 

项目名右键--->maven-->Update Project...

 

 

 

直接ok就行

 

 

 

 

 

导jar包

 

在浏览器中搜索mvn(在Microsoft Bing浏览器搜索)

 

 

 

Maven Repository: Search/Browse/Explore (mvnrepository.com)

 

在搜索栏中输入logback(日志)

 

 

 

选择1.2.3版本

 

 

 

复制到pom.xml中

 

在搜索spring web

 

 

 

选择5.2.20

 

 

 

同上个步骤

 

其他jar包同样

 

 

 

在pom.xml中

 

<dependencies>

<!-- https://mvnrepository.com/artifact/org.springframework/spring-webmvc -->

<!-- Spring MVC -->

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-webmvc</artifactId>
