我使用JAXB来创建文件夹和文件层次结构

我的模特:

@XmlRootElement
public class Root {

    @XmlAttribute
    private String path;

    @XmlElement(name = "dir")
    private ArrayList<Dir> rootContentDirs = null;

    @XmlElement(name = "file")
    private ArrayList<FileObj> rootContentFiles = null;


    public void setRootContentDirs(ArrayList<Dir> rootContentDirs) {
        this.rootContentDirs = rootContentDirs;
    }

    public void setRootContentFiles(ArrayList<FileObj> rootContentFiles) {
        this.rootContentFiles = rootContentFiles;
    }

    public void setPath(String path) {
        this.path = path;
    }
 }

public class Dir {

    @XmlAttribute
    private String name;

    @XmlElement(name = "dir")
    private ArrayList dirs = null;

    @XmlElement(name = "file")
    private ArrayList files = null;

    public …

我项目的结构:

-src
--main
---java
----makers
-----SomeClass
---resources
----htmlPattern.vm

如何告诉SomeClass关于htmlPattern.我尝试这样的事情:

    VelocityEngine ve = new VelocityEngine();
    Properties properties = new Properties();
    properties.setProperty("resource.loader", "file");
    properties.setProperty("file.resource.loader.class", "org.apache.velocity.runtime.resource.loader.FileResourceLoader");
    properties.setProperty("file.resource.loader.path", "resources");
    properties.setProperty("file.resource.loader.cache", "true");
    properties.setProperty("file.resource.loader.modificationCheckInterval", "2");
    ve.init(properties);

    Template t = ve.getTemplate("htmlPattern.vm", "utf-8");

怎么了？IDE说:

org.apache.velocity.exception.ResourceNotFoundException: Unable to find resource 'htmlPattern.vm'

我在尝试更新实体列表（作业）时遇到错误：

Multiple representations of the same entity [com.introlabsystems.upworkscraper.model.entities.Skill#42] are being merged. Detached: [Skill(id=42, skillName=Web Scraping)]; Detached: [Skill(id=42, skillName=Web Scraping)]

我认为这是三个实体与技能实体具有多对多关系的情况。

@Entity
public class Job {

  @Id
  @Column(unique = true, nullable = false)
  @SerializedName(value = "ciphertext")
  private String id;
  @Column(length = 2048)
  private String title;
  @Column(columnDefinition = "TEXT")
  @JsonAdapter(value = DescriptionAdapter.class)
  private String description;
  @SerializedName(value = "subcategory2")
  private String category;

  @ManyToMany(cascade = {
      CascadeType.MERGE
  }, fetch = FetchType.EAGER)
  @JoinTable(
      joinColumns = {@JoinColumn(name = "job_id")},
      inverseJoinColumns = {@JoinColumn(name = "skill_id")}
  )
  @JsonAdapter(value …
