Java 懒惰加载奇怪的行为

java hibernate spring jpa

Java 懒惰加载奇怪的行为,java,hibernate,spring,jpa,lazy-loading,Java,Hibernate,Spring,Jpa,Lazy Loading,我正在用SpringMVC[Layers:Controller->Service->DAO->Entities]创建web应用程序，我遇到了一个延迟加载的问题，这让我很困惑。一般来说，有以下关系。我有一个帐户[实体]，它可以有许多单词[实体]，许多单词可以分配给许多帐户，因此这是@ManyToMany 账户主体 @Entity @Table(name = "account") @Inheritance(strategy = InheritanceType.JOINED) publ

我正在用SpringMVC[Layers:Controller->Service->DAO->Entities]创建web应用程序，我遇到了一个延迟加载的问题，这让我很困惑。一般来说，有以下关系。我有一个帐户[实体]，它可以有许多单词[实体]，许多单词可以分配给许多帐户，因此这是@ManyToMany

账户主体

  @Entity
  @Table(name = "account")
  @Inheritance(strategy = InheritanceType.JOINED)
  public class Account {

  ...

  @ManyToMany(cascade=CascadeType.ALL, fetch = FetchType.LAZY, targetEntity = Word.class)
  @JoinTable(name = "account_word", joinColumns = {@JoinColumn(name="account_id")}, inverseJoinColumns = {@JoinColumn(name="word_id")})
  private List<Word> words;

  public List<Word> getWords() {
      return words;
  }

  public void setWords(List<Word> words) {
      this.words = words;
  }
  }

  @Entity
  @Table(name = "word")
  @Inheritance(strategy = InheritanceType.JOINED)
  public class Word {

  ...

  @Basic
  @NotBlank
  @Column(name = "word")
  private String word;

  @ManyToMany(cascade=CascadeType.ALL, fetch = FetchType.LAZY)
  @JoinTable(name = "account_word", joinColumns = {@JoinColumn(name="word_id")}, inverseJoinColumns = {@JoinColumn(name="account_id")})
  private List<Account> accounts;

  public List<Account> getAccounts() {
      return accounts;
  }

  public void setAccounts(List<Account> accounts) {
      this.accounts = accounts;
  }

  ...

  }
只是为了测试，但它的发生至关重要！没有它，我会变得懒洋洋的初始化异常，我找不到发生这种情况的原因。当我评论这个片段时，我得到：
