java开发常用命令

• 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"/>

• 线上部署
  netstat -lntp，查看端口对应的进程
  
  ps -ef|grep java，查看运行的java项目
  
  nginx/sbin/nginx，运行nginx，重启-s reload，停止-s stop，配置vi nginx/conf/nginx.conf，日志tail -f nginx/logs/access.log
  resin/bin/resin.sh start，运行resin，重启restart，停止stop，配置vi resin/conf/resin.xml，日志tail -f resin/log/jvm-app-0.log
  ifconfig，查看IP地址；
  df -hlT，查看存储；top，查看运行状态
