业务逻辑
登记保存之后，处理完成业务逻辑，发送全文检索事件
//附加类型对应的附件ids
Map<String, List<String>> attCategoryToAttIds = new HashMap<String, List<String>>();
attCategoryToAttIds.put(cmpRecord.getFileCategory(), files==null?null:files.stream().map(d->d.getId()).collect(Collectors.toList()));
//处理监听事件所需要的数据
Map<String,Object>eventData = Utils.buildMap("recordId", cmpRecord.getId(),"newRecord", true,"attCategoryToAttIds", attCategoryToAttIds);
//创建全文检索事件
DomainEvent de = new DefaultDomainEvent(cmpRecord.getId() + "_Handle_CmpRecord_FullTextSearch", operateInfo, ExecutePoint.CURR_THREAD,
eventData, new Date(), "Handle_CmpRecord_FullTextSearch");
//发布事件
DomainEventPublisherFactory.getRegisteredPublisher().publishEvent(de);

全文检索实体
@Entity
@Table(

@Index(name="idx_TV_FULLTEXT_SEARCH2",columnList="contentType")
}
)

@Id
@Column(length=200)
private String id;
private RelateProjValObj mainProj;//来源相关件
@Lob
@Type(type="org.hibernate.type.TextType")
private String content;//检索内容
@Column(length=100)
private String contentType;//检索类型
@Column(length=100)
private Date lastUpdateDate;//最后更新时间
public String getId() {
return id;
}
public String getContent() {
return content;
}

}

return mainProj;
}

}
存储数据格式
查询
sql大致就是这样的逻辑
select tv.id from tv_cmp_dw_query tv join tv_fulltext_search tvs on tv.id = tvs.proj_id where tvs.contet_type in () and conent like '%测试%'
