我的應用程序使用Hibernate 5.02和Wildfly 10與PostgreSQL 9.5數據庫。我試圖對通過NamedQuery構造的實體中的@OneToMany集合啓用過濾器。不幸的是，它好像只是忽略了過濾器。以下是不同的組件，爲便於閱讀而進行了編輯。被忽略的休眠過濾器
@NamedNativeQueries({
@NamedNativeQuery(
name = "getAnalystProcess",
query = "SELECT * FROM analysis.analystprocess WHERE id = :processId",
resultClass = AnalystProcessEntity.class
)})
@FilterDef(
name = "analystProcessUnanalyzedMsgsFilter",
parameters = { @ParamDef(name = "processIds", type = "integer"), @ParamDef(name = "analystIds", type = "integer") })
@Filter(name = "analystProcessUnanalyzedMsgsFilter", condition = "analystprocess_id IN (:processIds) AND id NOT IN (SELECT msg_id FROM analysis.analyzedmsg WHERE analyst_id IN (:analystIds) AND analystprocess_id IN (:processIds)) ORDER BY process_msg_id")
@Entity
@Table(name = "analystprocess", schema = "analyst")
public class AnalystProcessEntity implements JPAEntity {
public static final String GET_PROCESS = "getAnalystProcess";
public static final String MSG_FILTER = "analystProcessUnanalyzedMsgsFilter";
public static final String MSG_FILTER_PROC_ID_PARAM = "processIds";
public static final String MSG_FILTER_ANALYST_ID_PARAM = "analystIds";
private static final long serialVersionUID = 1L;
...
@OneToMany(fetch = FetchType.LAZY, orphanRemoval = true, mappedBy = "process")
@OrderColumn(name = "process_msg_id")
@LazyCollection(LazyCollectionOption.EXTRA)
private List<MsgEntity> msgList;
@Entity
@Table(name = "msg", schema = "analyst")
public class MsgEntity implements JPAEntity {
...
@ManyToOne(cascade = CascadeType.ALL, optional = false)
@JoinColumn(name = "analystprocess_id", referencedColumnName = "id")
private AnalystProcessEntity process;
@Column(name = "process_msg_id")
private Integer processMsgId;
private void buildAnalystProcess() {
LOG.info("Building AnalystProcessEntity");
analystUser.getJdbcSession().enableFilter(AnalystProcessEntity.MSG_FILTER)
.setParameter(AnalystProcessEntity.MSG_FILTER_PROC_ID_PARAM, analystProcessId)
.setParameter(AnalystProcessEntity.MSG_FILTER_ANALYST_ID_PARAM, analystUser.getId());
Query query = analystUser.getJdbcSession().getNamedQuery(AnalystProcessEntity.GET_PROCESS)
.setParameter("processId", analystProcessId);
// Query query = analystUser.getJdbcSession().createNativeQuery("SELECT * FROM analysis.analystprocess WHERE id = :processId")
// .setParameter("processId", analystProcessId)
// .addEntity(AnalystProcessEntity.class);
analystProcess = (AnalystProcessEntity) query.getSingleResult();
CREATE TABLE analysis.analystprocess (
id SERIAL PRIMARY KEY,
name TEXT NOT NULL UNIQUE,
description TEXT,
created_date TIMESTAMP NOT NULL DEFAULT now(),
...
);
CREATE TABLE analysis.msg (
id SERIAL PRIMARY KEY,
analystprocess_id INTEGER NOT NULL REFERENCES analysis.analystprocess(id) ON DELETE CASCADE ON UPDATE CASCADE,
process_msg_id INTEGER NOT NULL,
constraint tbl_statusid_analystprocessid unique(status_id, analystprocess_id)
);
如上所見，我還試圖經由createNativeQuery代替getNamedQuery和沒有運氣構建AnalystProcessEntity類過濾器。
我還在硬編碼值中添加了一個defaultCondition到@FilterDef中，以查看它是否會執行默認條件，但它仍然沒有。
我試過@Filter上面的實體定義以及類定義上面。我偶然發現了一篇博客文章，它使得它聽起來像條件引用實體字段（變量名稱），而不是表格字段（列名稱）。試圖在表中的Entity和Postgres命名約定中堅持使用Java命名約定，所以我嘗試在條件中切換引用並無濟於事。
我在Hibernate中打開了SQL日誌記錄，並且條件沒有出現在任何地方，就好像它只是簡單地被忽略。
任何幫助將不勝感激！
