  • cd /d e:work2,更改至当前工作目录
    svnup.bat,批量更新所有项目
    @echo off
    for /D %%i in (.\*) do (
    echo %%i
    svn up %%i
    )
    host.bat,本地临时更改域名解析
    notepad C:\Windows\System32\drivers\etc\hosts
    db.bat,方便连接内网数据库
    @echo off
    set db=default_db
    if ""%1"" == ""data"" goto data
    if ""%1"" == ""user"" goto user
    goto end
    :data
    set db=data_db
    goto end
    :user
    set db=user_db
    goto end
    :end
    mysql -h192.168.1.202 -uroot -p123456 -D%db%
  • mvn install
    项目管理通常使用mvn,组件类项目可以mvn install提交到本地依赖库后供其它项目引用,使用Nexus私服的配置为:${M2_HOME}/conf/settings.xml
    <mirrors><mirror>
    <id>nexus</id><name>local</name><url>http://localhost:8079/nexus/content/groups/public/</url>
      <mirrorOf>central</mirrorOf>
    </mirror></mirrors>
    如果要使用mvn deploy提交构件(而不是他人check out源码并mvn install),还需要配置:${M2_HOME}/conf/settings.xml
    <servers><server><id>nexus</id><username>admin</username><password>admin123</password></server></servers>
    以及项目配置pom.xml
    <distributionManagement>
     <repository><id>nexus</id><name>local</name><url>http://localhost:8079/nexus/content/groups/public/</url>
      </repository></distributionManagement>
  • mvn war:exploded
    网站项目通常不必打包war,发布时直接用WinSCP同步WebContent目录即可,命令mvn war:exploded可以构建完整的可直接被tomcat加载运行的WebContent目录,同时调试java和jsp都很方便。
    一种方式是直接编译输出class到WebContent/WEB-INF/classes目录(这时WEB-INF/lib会有jar包),然后用tomcat直接加载WebContent目录
    <build>
        <resources><resource><directory>src/main/resources</directory></resource></resources>
        <outputDirectory>WebContent/WEB-INF/classes</outputDirectory>
        <plugins>
            <plugin>
                <artifactId>maven-war-plugin</artifactId>
                <version>2.1.1</version>
                <configuration>
                    <warSourceDirectory>WebContent</warSourceDirectory>
                    <webappDirectory>WebContent</webappDirectory>
                </configuration>
            </plugin>
        </plugins>
    </build>
    另一种方式是编译输出到另外的目录(class+jsp+jar等),这时需要将WebContent也加入Source并输出到目标目录以便调试jsp(使用WebContentLink链接),同时WebContent/WEB-INF/classes链接到真正目标目录${target}/WebContent/WEB-INF/classes
    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <maven.compiler.encoding>UTF-8</maven.compiler.encoding>
        <maven.compiler.source>1.7</maven.compiler.source>
        <maven.compiler.target>1.7</maven.compiler.target>
        <maven.test.skip>true</maven.test.skip>
        <targets.home>E:\work2\Servers\web</targets.home>
    </properties>
    <build>
        <directory>${targets.home}/${project.artifactId}/target</directory>
        <outputDirectory>${targets.home}/${project.artifactId}/WebContent/WEB-INF/classes</outputDirectory>
        <plugins>
            <plugin>
                <artifactId>maven-war-plugin</artifactId>
                <version>2.1.1</version>
                <configuration>
                    <warSourceDirectory>WebContent</warSourceDirectory>
                    <webappDirectory>${targets.home}/${project.artifactId}/WebContent</webappDirectory>
                </configuration>
            </plugin>
        </plugins>
    </build>
    调试运行或发布WebContent目录即可
    <Context docBase="E:\work2\Servers\web\MyWeb\WebContent" path="/MyWeb"/>
