maven

在$HOME\.m2\setting.xml 中配置

mirror

可以使用国内的aliyun mirror，提高下载速度

    <mirror>
      <id>aliyun</id>
      <name>aliyun maven</name>
      <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
      <mirrorOf>central</mirrorOf>
    </mirror>
    <mirror>  
      <id>jboss</id>  
      <mirrorOf>central</mirrorOf>  
      <name>JBoss Public Repository Group</name>  
     <url>http://repository.jboss.org/nexus/content/groups/public</url>  
    </mirror>

maven 使用代理服务

maven默认不使用代理服务器，在通过代理服务器访问网络的情况下无法连接到central仓库。

    <proxy>
      <id>group</id>
      <active>true</active>
      <protocol>http</protocol>
      <username></username>
      <password></password>
      <host>proxy.corp.com</host>
      <port>80</port>
      <nonProxyHosts>localhost</nonProxyHosts>
    </proxy>

导入Oracle JDBC Driver

由于需要Oracle官方授权，所以maven上无法下载ojdbc，需要自己下载，然后通过命令加载到本地maven库中

C:\apache-maven-3.3.9\bin\mvn install:install-file -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.4.0.0 -Dpackaging=jar -Dfile=D:\搜狗高速下载\ojdbc6.jar

添加依赖关系

<dependency>  
    <groupId>com.oracle</groupId>  
    <artifactId>ojdbc6</artifactId>  
    <version>11.2.4.0.0</version>  
</dependency>

JDBC 配置

spring.datasource.url=jdbc:oracle:thin:@192.168.100.1:1521:test
spring.datasource.username=test
spring.datasource.password=test
spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver

maven properties

设置源代码文本文件字符集

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.resources.sourceEncoding>UTF-8</project.resources.sourceEncoding>
    <spring.version>4.3.12.RELEASE</spring.version>
</properties>

maven plugin

compile plugin

设置Java编译之后的class文件版本

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.1</version>
    <configuration>
        <source>1.8</source>
        <target>1.8</target>
    </configuration>
</plugin>

dependency plugin

把依赖的lib复制到某个目录下

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-dependency-plugin</artifactId>
    <executions>
        <execution>
            <id>copy-dependencies</id>
            <phase>prepare-package</phase>
            <goals>
                <goal>copy-dependencies</goal>
            </goals>
            <configuration>
                <outputDirectory>target/classes/lib</outputDirectory>
                <outputDirectory>target/job/lib</outputDirectory>
                <overWriteIfNewer>true</overWriteIfNewer>
                <excludeGroupIds>
                    junit,org.hamcrest,org.mockito,org.powermock,${project.groupId},com.linkedin.azkaban
                </excludeGroupIds>
            </configuration>
        </execution>
        <execution>
            <phase>generate-sources</phase>
            <goals>
                <goal>sources</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <verbose>true</verbose>
        <detail>true</detail>
        <outputDirectory>${project.build.directory}</outputDirectory>
    </configuration>
</plugin>

resources plugin

把资源文件复制到某个目录下

    <artifactId>maven-resources-plugin</artifactId>
    <version>2.6</version>
    <executions>
        <execution>
            <id>copy-resources</id>
            <phase>package</phase>
            <goals>
                <goal>copy-resources</goal>
            </goals>
            <configuration>
                <outputDirectory>${basedir}/target/job</outputDirectory>
                <resources>
                    <resource>
                        <directory>job</directory>

                </resources>
            </configuration>

    <artifactId>maven-assembly-plugin</artifactId>
    <version>2.6</version>
    <configuration>
        <descriptors>
            <descriptor>src/main/assembly/zip.xml</descriptor>
        </descriptors>

    <executions>
        <execution>
            <id>make-assembly</id> <!-- this is used for inheritance merges -->
            <phase>package</phase> <!-- append to the packaging phase. -->
            <goals>
                <goal>single</goal> <!-- goals == mojos -->
            </goals>
        </execution>
    </executions>
</plugin>

zip.xml

fileSet->directory 需要打包文件所在的目录
fileSet->outputDirectory 相对压缩文件根目录的路径

<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0 http://maven.apache.org/xsd/assembly-1.1.2.xsd">
    <id>job</id>
    <baseDirectory>/</baseDirectory>
    <formats>
        <format>zip</format>
    </formats>
    <fileSets>
        <fileSet>
            <directory>${project.build.directory}/job</directory>
            <outputDirectory>job</outputDirectory>
        </fileSet>
        <fileSet>
            <directory>${project.build.directory}</directory>
            <outputDirectory>job/lib</outputDirectory>
            <includes>
                <include>*.jar</include>
            </includes>
