我们使用sourceforge项目.当我们试图推动时,然后mercurial abort:

$ hg push

pushing to ssh://<user>@hg.code.sf.net/p/loremipsum/code
searching for changes
remote: abort: abandoned transaction found - run hg recover!
abort: unexpected response: empty string

当我们尝试恢复时,这不起作用:

$ hg recover
no interrupted transaction available

该项目的其他程序员也有同样的问题.我们迷路了.

我们尝试用Guice重构一个项目.我们的想法是将所有语言界面绑定到一个像法语或波兰语这样的混合对象.

我们有一个绑定模块:

public class StandardModule extends AbstractModule {

    @Override
    protected void configure() {

       bind(Language.class).to(Polish.class);

    }
 }

以及使用此注入对象的classe(AboutDialog.java):

@Inject Language language;

public AboutDialog(JFrame parent) {
    super(parent, "", true);
    this.language=language;
    this.setTitle(language.getLanguageInUse().getString("AboutDialog.title"));
    this.parent = parent;
    try {
        jbInit();
    } catch (Exception e) {
        e.printStackTrace();
    }
    pack();
}

我们有结果:

java.lang.NullPointerException at net.sf.jmoney.gui.AboutDialog.<init>(AboutDialog.java:67)

第67行是:

this.setTitle(language.getLanguageInUse().getString("AboutDialog.title"));

我们的界面是:

public interface Language {

    public ResourceBundle getLanguageInUse();
}

波兰语课程是:

public class Polish implements Language {

    private ResourceBundle languageInUse;

    public Polish() {
        languageInUse = …

我按照本教程https://springframework.guru/spring-boot-restful-api-documentation-with-swagger-2/生成了庞大的文档。它正在工作，但是当我尝试在bean中添加一些验证时，我在文档中找不到这些信息：

@ApiOperation(value = "Creates a product",
        notes="Populates a product instance bla bla")
@RequestMapping(value = "/add", method = RequestMethod.POST, produces = "application/json")
public ResponseEntity saveProduct(  @Valid @RequestBody Product product){
    productService.saveProduct(product);
    return new ResponseEntity("Product saved successfully", HttpStatus.OK);
}

我的实体带有验证注释：

@Entity
public class Product {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
   // @ApiModelProperty(notes = "The database generated product ID")
    private Integer id;
    @Version
   // @ApiModelProperty(notes = "The auto-generated version of the product")
    @NotNull
    private Integer version;
   // @ApiModelProperty(notes = "The application-specific product ID" …

我想用scala和fremework Play 2.2来实例化Ebean项目的模型对象.我面临ID自动生成和类参数/抽象的问题:

   @Entity 
    class Task(@Required val label:String) extends Model{
      @Id 
      val id: Long
    }

object Task {
  var find: Model.Finder[Long, Task] = new Model.Finder[Long, Task](classOf[Long], classOf[Task])

  def all(): List[Task] = find.all.asScala.toList

  def create(label: String) {
   val task =  new Task(label)
   task.save
  }

  def delete(id: Long) {
    find.ref(id).delete
  }
}

错误:"类任务需要是抽象的,因为没有定义值id".有什么想法可以避免这个问题？
