Question

我在massindexer操作期间遇到了一个问题。

我使用JPA 2.0-cr-1，Hibernate搜索4.2.0.Final和hibernate 4.1.9.Final，以及lucene版本3.6.2。我也使用spring框架。

我使用Hibernate搜索4.2.0.Final代替Hibernate搜索3.3.0.Final似乎有问题。

我将实体User.java编入索引：

@Entity
@Table(name = "user", uniqueConstraints = {
    @UniqueConstraint(columnNames = "email"),
    @UniqueConstraint(columnNames = "login") })
@Indexed
@FullTextFilterDefs({
@FullTextFilterDef(name = "userFilterGroup", impl = UserFilterGroupFactory.class   ,cache=FilterCacheModeType.NONE),
@FullTextFilterDef(name = "userFilterAccountType", impl = LuceneStrFilterFactory.class ,cache=FilterCacheModeType.NONE)})
public class User extends TemporalBehavior implements java.io.Serializable {

/**
 * 
 */
private static final long serialVersionUID = -626437341655804022L;


public static final String[] SEARCH_FIELDS = new String[]{"id","login","email","profile.lastname","profile.firstname"};

private Integer id;

@Field(index=Index.YES, analyze=Analyze.YES, store=Store.NO)
@NotNull
@Size(min=1, max=255)
//@Size(min=6, max=255) //L'ancienne plateforme permet des login min=1
private String login;

@NotNull
@Size(min=1, max=255)
//@Size(min=6, max=255) //L'ancienne plateforme permet des pass min=1
private String password;

@Field(index=Index.YES, analyze=Analyze.YES, store=Store.NO)
@Email
private String email;

@Field(index=Index.YES, analyze=Analyze.YES, store=Store.NO)
private String partnerRef;

private Set<Contract> contracts = new HashSet<Contract>(0);
private Set<Contract> ownedContracts = new HashSet<Contract>();

    ....
    @ManyToMany(fetch = FetchType.LAZY, cascade=CascadeType.PERSIST)
@JoinTable(name = "user_contract", joinColumns = { @JoinColumn(name = "user_id", nullable = false, updatable = false) }, inverseJoinColumns = { @JoinColumn(name = "contract_id", nullable = false, updatable = false) })
public Set<Contract> getContracts() {
    return this.contracts;
}

    @OneToMany(mappedBy="owner")
public Set<Contract> getOwnedContracts() {
    return this.ownedContracts;
}

    ...

    }

我称之为Massindexer操作：

FullTextEntityManager fem = Search.getFullTextEntityManager(em);
    try {
        fem.createIndexer(User.class)
        .purgeAllOnStart(true)
        .optimizeAfterPurge( true )   
        .optimizeOnFinish( true )
        .batchSizeToLoadObjects(100)  
        .threadsForSubsequentFetching(8)  
        .threadsToLoadObjects(4)  
        .cacheMode(CacheMode.NORMAL)    // todo : It is recommended to leave cacheMode to CacheMode.IGNORE (the default), as in most reindexing situations the cache will be a useless additional overhead; 
        .startAndWait();
    } catch (InterruptedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

然后massindexer完成它的工作但是有一些错误（不适用于所有用户数据）：

有什么想法吗？

Answer 1

当您尝试持久存在其ID已存在的实体时，似乎会发生这种情况。如果你打算MassIndexer更新Contract记录，在给出的错误中，我相信你会想要将CascadeType注释更改为：CascadeType.ALL（或者CascadeType.SAVE_UPDATE）。

查看this question，进一步讨论此异常。

MassIndexer操作期间出错：传递给persist的分离实体，HSEARCH000058：HSEARCH000116
