我正在使用 JPA 在 Java EE（泽西岛）中创建一个应用程序，其中未初始化的实体存在问题。我有 3 个实体 Car、Owner、House，其中汽车可以有多个所有者，所有者可以拥有多个房屋。当我返回 (entityManager.find) Car 时，所有者被初始化。当我返回 House 时，Owner 已初始化，但 Car 未初始化。我希望能够调用 House.getOwner().getCar().getId() 之类的东西。现在我必须在 House 上调用 find，然后在 Owner 上调用 find 来获取 Car。我该如何解决？

@Entity
@Table(name = "House")
public class HouseEntity {

  @Id
  @Column(name = "id")
  @GeneratedValue(strategy = GenerationType.IDENTITY)
  private long id;

  @ManyToOne(fetch = FetchType.EAGER)
  @JoinColumn(name = "owner_id", nullable = false)
  private OwnerEntity owner;
}

@Entity
@Table(name = "Owner")
public class OwnerEntity {

  @Id
  @Column(name = "id")
  @GeneratedValue(strategy = GenerationType.IDENTITY)
  private long id;

  @ManyToOne(fetch = FetchType.EAGER)
  @JoinColumn(name = …

我在Jersey（在WildFly 8.1.0.Final上部署）上进行了RESTful应用程序，但是测试方法@DELETE出现问题。所有其他（GET，POST，PUT）均按预期工作。但是，在调用@DELETE时，我收到以下错误消息

Cross-Origin Resource Sharing (CORS) Filter: Unsupported HTTP method: DELETE

我通过Google Chrome：高级REST客户端中的插件测试RESTful接口。我该如何解决？

资源类：为了更好地说明，我删除了其他方法。

@Path(value = "destination")
@Produces({MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML})
@Consumes({MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML})
public class DestinationResource {

public DestinationResource() {}

@DELETE
@Path(value = "/{id}")
public Response deleteDestination(@PathParam("id") Long id) {
    //Doing something
    return Response.status(Response.Status.OK).build();
}

}

编辑：我添加了CORS.filter，但仍然可以正常工作。这是我的web.xml

我有Sonar分析的Android项目.我看到了所有问题但没有通过单元测试覆盖.我尝试了很多东西,但仍然无法使其正常工作.当我调用'gradlew createDebugCoverageReport'时,它将在build/reports/coverage/debug中创建包含大量文件(如report.xml和index.html)的目录,其中包含测试覆盖率数据.但在Coars的Coverage下,我得到的信息是"此组件没有覆盖详细信息".我怎样才能让它发挥作用？

命令序列:

gradlew clean assemble
gradlew createDebugCoverageReport
gradlew sonarRunner

的build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "cz.meteocar.unit"
        minSdkVersion 16
        targetSdkVersion 20

        versionName "1.0.2"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

            }
            debug {

                testCoverageEnabled = true

我试图通过本教程WADL生成工具使用maven-wadl-plugin生成WADL .但我总是得到以下错误.有人能告诉我问题在哪里,因为我无法看到它.刚才添加了pom.xml.

这是以下错误.
