通过geotools读写shp文件

依赖jar包

读取shp

	public static void main(String[] path) {
		DbaseFileReader reader = null;
		try {
			reader = new DbaseFileReader(new ShpFiles("C:\\Users\\lilei3774\\Desktop\\wuhan\\1\\split-hanzi\\poi.shp"), false,
					Charset.forName("utf-8"));
			DbaseFileHeader header = reader.getHeader();
			int numFields = header.getNumFields();

			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) {

				try {
					reader.close();
				} catch (Exception e) {
				}
			}
		}
	}

　　

	public static void main(String[] args) {
