Question

我正在尝试将Hibernate Search集成到已经运行的Play Framework应用程序中。我有建立索引的问题，或者那就是我认为的问题。

我有一个用户：

var query = from a in addressRepository.GetAll() select a;

IList<AddressSearchResponseDto> result = Mapper.Map<IList<Address>, IList<AddressSearchResponseDto>>(query.ToList());

这是我的persistence.xml：

http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd” 版本= “2.0” ＆GT;

@Indexed
@Entity
public class User extends Model {
    @Field
    public String firstname;
    @Field
    public String lastname;
    @Field
    public String email;
}

因此，我认为索引的构建（对于数据库中已存在的数据）应该在GlobalAdmin对象的<persistence-unit name="default" transaction-type="RESOURCE_LOCAL"> <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider> <non-jta-data-source>DefaultDS</non-jta-data-source> <class>models.User</class> <properties> <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/> <property name="hibernate.hbm2ddl.auto" value="update"/> <property name="hibernate.search.default.directory_provider" value="filesystem"/> <property name="hibernate.search.default.indexBase" value="/Users/<user>/lucene/indexes"/> </properties> </persistence-unit>中进行。我使用onStart来调用索引器：

JPA.withTransaction

问题是我得到了：

JPA.withTransaction(new F.Callback0() {
    @Override
    public void invoke() throws Throwable {
        FullTextEntityManager fullTextEntityManager = org.hibernate.search.jpa.Search.getFullTextEntityManager(JPA.em());
        try {
            fullTextEntityManager.createIndexer().startAndWait();
        } catch (Exception e) {
            Logger.error(e.getMessage());
        }
    }
});

感谢您的帮助。

编辑：

我在控制器中的搜索方法：

正如在建议的评论中，我在'onStart'中取消注释了Indexer。

这是我第一次尝试使用Hibernate Search的方法。但是，这不会返回任何内容。

您的问题似乎不在于直接搜索。看看堆栈跟踪，似乎你的JDBC连接已经用完了。我自己不认识BoneCP，但它似乎是一个JDBC池库。你的配置是什么？您是否尝试过增加连接池大小？
