Bat系列教程

项目实战

其目录下面的脚本文件如下，有些重复的内容，这里不做过多介绍，有遇到什么不会的内容可以查看Bat系列教程

下面我们一一来分析其里面的内容，为了避免文本过长，每个文件单独一篇文章讲解。

  1. # catalina.bat
  2. :: 我们重点讲解bat语法以及模仿别人如何编写，从他人代码中丰富自己，不对脚本中的逻辑关系进行过多介绍。

  20. rem Start/Stop Script for the CATALINA Server
  21. rem
  22. rem Environment Variable Prerequisites
  23. rem
  24. rem   Do not set the variables in this script. Instead put them into a script
  25. rem   setenv.bat in CATALINA_BASE/bin to keep your customizations separate.
  26. rem
  27. rem   WHEN RUNNING TOMCAT AS A WINDOWS SERVICE:
  28. rem   Note that the environment variables that affect the behavior of this
  29. rem   script will have no effect at all on Windows Services. As such, any
  30. rem   local customizations made in a CATALINA_BASE/bin/setenv.bat script
  31. rem   will also have no effect on Tomcat when launched as a Windows Service.
  32. rem   The configuration that controls Windows Services is stored in the Windows
  33. rem   Registry, and is most conveniently maintained using the "tomcatXw.exe"
  34. rem   maintenance utility, where "X" is the major version of Tomcat you are
  35. rem   running.
  36. rem
  37. rem   CATALINA_HOME   May point at your Catalina "build" directory.
  38. rem
  39. rem   CATALINA_BASE   (Optional) Base directory for resolving dynamic portions
  40. rem                   of a Catalina installation.  If not present, resolves to
  41. rem                   the same directory that CATALINA_HOME points to.
  42. rem
  43. rem   CATALINA_OPTS   (Optional) Java runtime options used when the "start",
  44. rem                   "run" or "debug" command is executed.
  45. rem                   Include here and not in JAVA_OPTS all options, that should
  46. rem                   only be used by Tomcat itself, not by the stop process,
  47. rem                   the version command etc.
  48. rem                   Examples are heap size, GC logging, JMX ports etc.
  49. rem
  50. rem   CATALINA_TMPDIR (Optional) Directory path location of temporary directory
  51. rem                   the JVM should use (java.io.tmpdir).  Defaults to
  52. rem                   %CATALINA_BASE%\temp.
  53. rem
  54. rem   JAVA_HOME       Must point at your Java Development Kit installation.
  55. rem                   Required to run the with the "debug" argument.
  56. rem
  57. rem   JRE_HOME        Must point at your Java Runtime installation.
  58. rem                   Defaults to JAVA_HOME if empty. If JRE_HOME and JAVA_HOME
  59. rem                   are both set, JRE_HOME is used.
  60. rem
  61. rem   JAVA_OPTS       (Optional) Java runtime options used when any command
  62. rem                   is executed.
  63. rem                   Include here and not in CATALINA_OPTS all options, that
  64. rem                   should be used by Tomcat and also by the stop process,
  65. rem                   the version command etc.
  66. rem                   Most options should go into CATALINA_OPTS.
  67. rem
  68. rem   JAVA_ENDORSED_DIRS (Optional) Lists of of semi-colon separated directories
  69. rem                   containing some jars in order to allow replacement of APIs
  70. rem                   created outside of the JCP (i.e. DOM and SAX from W3C).
  71. rem                   It can also be used to update the XML parser implementation.
  72. rem                   Defaults to $CATALINA_HOME/endorsed.
  73. rem
  74. rem   JPDA_TRANSPORT  (Optional) JPDA transport used when the "jpda start"
  75. rem                   command is executed. The default is "dt_socket".
  76. rem
  77. rem   JPDA_ADDRESS    (Optional) Java runtime options used when the "jpda start"
  78. rem                   command is executed. The default is 8000.
  79. rem
  80. rem   JPDA_SUSPEND    (Optional) Java runtime options used when the "jpda start"
  81. rem                   command is executed. Specifies whether JVM should suspend
  82. rem                   execution immediately after startup. Default is "n".
  83. rem
  84. rem   JPDA_OPTS       (Optional) Java runtime options used when the "jpda start"
  85. rem                   command is executed. If used, JPDA_TRANSPORT, JPDA_ADDRESS,
  86. rem                   and JPDA_SUSPEND are ignored. Thus, all required jpda
  87. rem                   options MUST be specified. The default is:
  88. rem
  89. rem                   -agentlib:jdwp=transport=%JPDA_TRANSPORT%,
  90. rem                       address=%JPDA_ADDRESS%,server=y,suspend=%JPDA_SUSPEND%
  91. rem
  92. rem   JSSE_OPTS       (Optional) Java runtime options used to control the TLS
  93. rem                   implementation when JSSE is used. Default is:
  94. rem                   "-Djdk.tls.ephemeralDHKeySize=2048"
  95. rem
  96. rem   LOGGING_CONFIG  (Optional) Override Tomcat's logging config file
  97. rem                   Example (all one line)
  98. rem                   set LOGGING_CONFIG="-Djava.util.logging.config.file=%CATALINA_BASE%\conf\logging.properties"
  99. rem
  100. rem   LOGGING_MANAGER (Optional) Override Tomcat's logging manager
  101. rem                   Example (all one line)
  102. rem                   set LOGGING_MANAGER="-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager"
  103. rem
  104. rem   TITLE           (Optional) Specify the title of Tomcat window. The default
  105. rem                   TITLE is Tomcat if it's not specified.
  106. rem                   Example (all one line)
