我只是在为开源软件 Geonetwork 测试一些东西，现在我想将一个形状文件从我的 postGIS 数据库导出到我的计算机，但我无法测试它，因为我总是收到一个 findbugs 警告：硬编码引用 org 中的绝对路径名。 fao.geonet.services.resources.Download.exec（元素，ServiceContext）

有谁知道如何抑制或避免这个警告？或者我如何测试导出是否有效的另一种解决方案？

这是代码：

  ` Map parameter1= new HashMap();
    parameter1.put("dbtype", "postgis");        
    parameter1.put("host", "localhost");        
    parameter1.put("port", "5433");  
    parameter1.put("database", "geonetwork");
    parameter1.put("schema", "mydata");
    parameter1.put("user", "postgres");        
    parameter1.put("passwd", "dominik1");
    parameter1.put("Expose primary keys", false);
    parameter1.put(PostgisNGDataStoreFactory.VALIDATECONN, true);
    parameter1.put(PostgisNGDataStoreFactory.MAX_OPEN_PREPARED_STATEMENTS, 100);
    parameter1.put(PostgisNGDataStoreFactory.LOOSEBBOX, true);
    parameter1.put(PostgisNGDataStoreFactory.PREPARED_STATEMENTS, true); 
    System.out.println("parameter1: " + parameter1);

    DataStore pds = new PostgisNGDataStoreFactory().createDataStore(parameter1);
    FeatureSource fs = pds.getFeatureSource("dano");

    SimpleFeatureCollection fc = (SimpleFeatureCollection) fs.getFeatures();
    SimpleFeature f = (SimpleFeature) fc.toArray()[0];

    // create shapefile

    File sfile = new File("C:/Users/Tinis/Downloads/dano.zip");            
    parameter1 = new HashMap();
    parameter1.put("url", sfile.toURI().toURL());
    parameter1.put("create spatial index", Boolean.FALSE);


    DirectoryDataStore dds = new DirectoryDataStore(new File(sfile.getAbsolutePath()), (FileStoreFactory) new ShapefileDataStoreFactory.ShpFileStoreFactory(new ShapefileDataStoreFactory(), parameter1));    

    dds.createSchema(fc.getSchema());
    String typeName = dds.getTypeNames()[0];
    SimpleFeatureSource featureSource = dds.getFeatureSource(typeName);
    SimpleFeatureStore featureStore = (SimpleFeatureStore) featureSource;

    // write data to shapefile
    Transaction t = new DefaultTransaction("addTransaction");
    featureStore.setTransaction(t);
    featureStore.addFeatures(fc);
    t.commit();
    t.close(); `

给出 findbugs 警告的行就在 // create shapefile 注释之后

我希望有人可以帮助我解决这个问题。谢谢！

制作一个带有条目的 xxx.properties 文件（ResourceBundle）：

danoZip = C:/Users/Tinis/Downloads/dano.zip

并间接进行：

ResourceBundle bundle = ResourceBundle.getBundle("xxx");

String danoZipPath = bundle.getString("danoZip");

File sfile = new File(danoZipPath);

通过这种方式，您可以将硬编码文件的配置放入可配置的属性文件中。

您可以使用过滤器文件来描述要忽略的错误。
