在做项目的时候遇到maven相关配置问题，以此做记录
[后面抽时间会写一些分布式微服务相关的文章,只有粉丝才能看到哟！！！！]
Maven相关配置

文章目录
1.配置阿里镜像
在maven的settiong.xml中配置阿里镜像
<mirrors>
<mirror>
<id>nexus-aliyun</id>
<mirrorOf>central</mirrorOf>
<name>Nexus aliyun</name>
<url>http://maven.aliyun.com/nexus/content/groups/public</url>
</mirror>
</mirrors>
注意:不要有中文字符
2.配置tomcat7插件
在pom.xml中配置tomcat7插件
<build>
<plugins>
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.2</version>
<configuration>
<!-- 指定端口 -->
<port>9101</port>
<!-- 请求路径 -->
<path>/</path>
</configuration>
</plugin>
</plugins>
</build>
3.指定jdk、mapper、tomcat7插件
指定jdk版本、mapper映射路径、配置tomcat7插件
<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">

<uriEncoding>UTF-8</uriEncoding><!-- 非必需项 -->
</configuration>
</plugin>
</plugins>
</build>
</project>
4.手动把jar包导入maven仓库
Maven 安装 JAR 包的命令是：
mvn install:install-file -Dfile=jar包的位置 -DgroupId=上面的groupId -DartifactId=上面的artifactId -Dversion=上面的version -Dpackaging=jar
例如：
我下载的这个 jar 包是放到了 D:\mvn 目录下(D:\mvn\spring-context-support-3.1.0.RELEASE.jar)
那么我在 cmd 中敲入的命令就应该是：
mvn install:install-file -Dfile=D:\mvn\spring-context-support-3.1.0.RELEASE.jar -DgroupId=org.springframework -DartifactId=spring-context-support -Dversion=3.1.0.RELEASE -Dpackaging=jar
CMD界面提示成功后，在本地仓库将看到此jar包，在pom.xml文件中正常引用即可。
5.解决 Maven 无法自动下载依赖的问题
使用 Maven 提供的插件来解决
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-install-plugin</artifactId>
<version>2.5.2</version>
<executions>
<execution>
<id>install-external-kaptcha</id>
<!-- 触发时机：执行 mvn clean 命令时自动触发插件 -->
<phase>clean</phase>
<configuration>
<!-- 存放依赖文件的位置 -->
<file>${project.basedir}/libs/kaptcha-2.3.jar</file>
<repositoryLayout>default</repositoryLayout>
<!-- 自定义 groupId -->
<groupId>com.google.code.kaptcha</groupId>
<!-- 自定义 artifactId -->
<artifactId>kaptcha</artifactId>
<!-- 自定义版本号 -->
<version>2.3</version>
<!-- 打包方式 -->
<packaging>jar</packaging>
<!-- 是否自动生成 POM -->
<generatePom>true</generatePom>
</configuration>
<goals>
<goal>install-file</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
通过该插件，我们可以在执行 mvn clean 命令时将项目所需要的依赖自动安装进本地仓库
6.解决Maven项目下使用Mybatis时，找不到mapper映射文件
<!-- 如果不添加此节点，mybatis的mapper.xml文件都会被漏掉。 -->
<build>
<plugins>
<!-- 资源文件拷贝插件 -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>2.7</version>
<configuration>
<encoding>UTF-8</encoding>
</configuration>
</plugin>
</plugins>
<resources>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>false</filtering>
</resource>
</resources>
</build>
另一种
<resources>
<resource>
<directory>src/main/resources</directory>
<includes>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>false</filtering>
</resource>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.xml</include>
</includes>
<filtering>false</filtering>
</resource>
</resources>
7.Spring Boot 使用Maven打包之后运行jar找不到主属性清单的问题
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<!-- 指定启动类的路径-->
<maimClass>com.itmayiedu.app.EureKaServer</maimClass>
</configuration>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
