geotools 写 shp文件 中文属性乱码

在使用Geotools写shp文件时，中文属性乱码问题可能是因为编码不一致所致。可以尝试在写入shp文件之前，设置相应的编码格式，例如：

// 创建shapefile数据存储对象
Map<String, Serializable> params = new HashMap<>();
params.put("url", new File("path/to/shapefile.shp").toURI().toURL());
params.put("create spatial index", Boolean.TRUE);
DataStore newDataStore = DataStoreFinder.getDataStore(params);

// 定义shapefile属性字段
SimpleFeatureType TYPE = DataUtilities.createType("Location",
        "the_geom:Point:srid=4326," + // 必须包含一个几何属性
        "name:String");

// 设置中文属性字段编码
((ShapefileDataStore)newDataStore).setCharset(Charset.forName("GBK"));

// 创建要素并写入shapefile文件
SimpleFeatureBuilder featureBuilder = new SimpleFeatureBuilder(TYPE);
GeometryFactory geometryFactory = JTSFactoryFinder.getGeometryFactory();
Point point = geometryFactory.createPoint(new Coordinate(116.404, 39.915));
featureBuilder.add(point);
featureBuilder.add("北京市");
SimpleFeature feature = featureBuilder.buildFeature(null);
Transaction transaction = newDataStore.getTransaction();
SimpleFeatureSource featureSource = newDataStore.getFeatureSource(TYPE.getName().getLocalPart());
if (featureSource instanceof SimpleFeatureStore) {
    SimpleFeatureStore featureStore = (SimpleFeatureStore) featureSource;
    featureStore.setTransaction(transaction);
    try {
        featureStore.addFeatures(DataUtilities.collection(feature));
        transaction.commit();
    } catch (Exception e) {
        transaction.rollback();
    } finally {
        transaction.close();
    }
}
newDataStore.dispose();

在上述代码中，通过`((ShapefileDataStore)newDataStore).setCharset(Charset.forName("GBK"));`来设置中文属性字段的编码格式为GBK。可以根据实际情况进行调整。
