本文详细介绍了MapServer地图配置过程中的关键步骤与注意事项，包括如何正确设置LabelItem以确保地图上的文字显示正常，以及如何处理不同文件编码和数据库编码的问题。通过具体的mapfile配置示例，读者可以了解到如何配置地图样式、图层数据源等。

搞了一两天了，记下吧，唉
关键是下面的map配置
首先是LabelItem，对应属性的字段
FONT simhei//这个font必须在   FONTSET http://www.cnblogs.com/gmap/etc/fonts.txt列表中存在，并且有字体文件
还要加上个   Encoding gb2312
如果是shp文件，保证dbf文件是utf8编码（我用的是utf8）
如果是postgis数据库，保证数据库是utf8编码，shp文件导入数据库是gb2312编码
在数据库迁移时，用备份回存会发生问题，即使你的数据库是utf8编码
最好是先做成sql文件，重新执行导入数据

LabelItem "Name"
CLASSITEM "CLASS"
CLASS
    EXPRESSION "AH"
    TEMPLATE "ttt_query.html"
    NAME "Cities"
    LABEL
      COLOR 255 0 0
      FONT simhei
      TYPE truetype
      SIZE 8
      POSITION AUTO
      PARTIALS FALSE
      OUTLINECOLOR 255 255 255
      Encoding gb2312
    END
