需要从Web系统中导出Shape格式数据文件，并使用AicMap打开。

中间件在系统中扮演连接数据和服务的角色。GeoTools承担了从各种数据源（如PostGIS，GML，Shapefile，WFS）读取数据并将数据标准化的工作。Feature接口就定义在GeoTools中，不同数据源的数据读出后被统一成包含一个Geometry成员（定义在JTS中）的Feature接口的实现。这样，进一步的操作只需面向Feature即可，省去了高层软件对于不同数据源的解读过程。另外，GeoTools还是OpenGIS标准的全面实现，其中包括Filter、坐标转换、GML。

GeoTools简单说明

• 下面将分为2.7.2和10.0两种版本的写法演示，不同版本之间的写法略有不同。
• shape格式文件最少包含3个文件，他们的后缀是：.shp, .dbf, .shx。
• .shp存储地理形状和位置信息，.dbf存储属性信息，.shx是索引文件。
• 在读取文件和输出文件的时候千万要注意到中文字符乱码问题，测试发现读取和输出的时候使用GBK或UTF-8，不对字符串进行转码，因为没有用，在对应方法中设置数据格式才对。（ShapefileDataStore的setStringCharset(Charset.forName("GBK"));等方法）

GeoTools-2.7.2-单独读取DBF文件（未测试）

public void readDBF(String path) {DbaseFileReader reader = null;  try {  reader = new DbaseFileReader(new ShpFiles(path), false, Charset.forName("GBK"));  DbaseFileHeader header = reader.getHeader();  int numFields = header.getNumFields();  //迭代读取记录  while (reader.hasNext()) {  try {  Object[] entry = reader.readEntry();  for (int i=0; i<numFields; i++) {  String title = header.getFieldName(i);  Object value = entry[i];  System.out.println(title+"="+value);  }  } catch (Exception e) {  e.printStackTrace();  }  }  } catch (Exception e) {  e.printStackTrace();  } finally {  if (reader != null) {  //关闭  try {reader.close();} catch (Exception e) {}  }  }
}
