我正在尝试使用Java以编程方式从XSD文件生成JAXB类.我使用以下代码片段来实现:

....
import java.io.File;
import java.io.IOException;
import org.xml.sax.InputSource;
import com.sun.codemodel.JCodeModel;
import com.sun.tools.xjc.api.S2JJAXBModel;
import com.sun.tools.xjc.api.SchemaCompiler;
import com.sun.tools.xjc.api.XJC;
....
....
public static void generateJaxb(String schemaPath,
                                    String outputDirectory,
                                        String packageName) throws DataLoadingException
{
    try {
        // Setup schema compiler
        SchemaCompiler sc = XJC.createSchemaCompiler();
        sc.forcePackageName(packageName);

        // Setup SAX InputSource
        File schemaFile = new File(schemaPath);
        InputSource is = new InputSource(schemaFile.toURI().toString());

        // Parse & build
        sc.parseSchema(is);
        S2JJAXBModel model = sc.bind();

        JCodeModel jCodeModel = model.generateCode(null, null);
        jCodeModel.build(new File(outputDirectory));
    } catch (IOException exec) {
        LOGGER.error("Error while generating JAXB …

我有许多由JAXB的xsd2java生成的类.我需要在编译时使用特定注释对所有这些类进行注释(例如使用lombok注释).有没有办法做到这一点,例如一些代码生成工具？

我想在生成“Doc”类之前生成“@java.lang.SuppressWarnings("all")”。

问题：jaxb2-annotate-plugin 不生成注释。

我目前有这段代码：

Map<Site, LinkedList<Site.Hosts.Host>> map = new HashMap<Site, LinkedList<Site.Hosts.Host>>();

for (PerformanceCounter element : pc) {
  Site s = new Site();

  s.id = Short.parseShort(element.getSite_id());
  s.name = element.getSite_name();
  s.location = element.getSite_location();

  Site.Hosts.Host h = new Site.Hosts.Host();
  h.id = Short.parseShort(element.getHost_id());

  if (!map.containsKey(s)) {
    map.put(s, new LinkedList<Site.Hosts.Host>());
  } else {
    map.get(s).add(h);
  }
}

我正在阅读的 PerformanceCounters 列表是：

1, C-01, New York, 1001
1, C-01, New York, 1002
1, C-01, New York, 1003

其中 101 是 ID，C-01 是名称，纽约是位置。

不幸的是，我的代码为我的地图创建了 3 个键值。

我无法生成 1 个键和 3 个值LinkedList …
