我的项目最初是由 seam-gen 生成的，并且动作“List”bean 没有像我预期的那样工作。限制数组具有表中的所有属性，并且表现得好像所有参数都是必需的。请参阅下面的列表：

package br.com.autenticis.comvenif_red_web.session;

import br.com.autenticis.comvenif_red_web.entity.*;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.framework.EntityQuery;
import java.util.Arrays;

@Name("t233Ev01List")
public class T233Ev01List extends EntityQuery<T233Ev01> {

 private static final String EJBQL = "select t233Ev01 from T233Ev01 t233Ev01";

 private static final String[] RESTRICTIONS = {
   //"lower(t233Ev01.placaUnica) like lower(concat(#{t233Ev01List.t233Ev01.placaUnica},'%'))",}; 
   "lower(t233Ev01.placaUnica) like lower(concat(#{t233Ev01List.t233Ev01.placaUnica},'%'))",
   "lower(t233Ev01.renavam) like lower(concat(#{t233Ev01List.t233Ev01.renavam},'%'))",
   "lower(t233Ev01.numIdentProprietario) like lower(concat(#{t233Ev01List.t233Ev01.numIdentProprietario},'%'))",
   "lower(t233Ev01.nomeProprietario) like lower(concat(#{t233Ev01List.t233Ev01.nomeProprietario},'%'))",
   "lower(t233Ev01.anoFabricacao) like lower(concat(#{t233Ev01List.t233Ev01.anoFabricacao},'%'))",
   "lower(t233Ev01.anoModelo) like lower(concat(#{t233Ev01List.t233Ev01.anoModelo},'%'))",
   "lower(t233Ev01.ufByUfEmissao) like lower(concat(#{t233Ev01List.t233Ev01.ufByUfEmissao},'%'))",
   "lower(t233Ev01.numeroCrv) like lower(concat(#{t233Ev01List.t233Ev01.numeroCrv},'%'))",
   "lower(t233Ev01.dataEmissao) like lower(concat(#{t233Ev01List.t233Ev01.dataEmissao},'%'))",
   "lower(t233Ev01.numeroVia) like lower(concat(#{t233Ev01List.t233Ev01.numeroVia},'%'))",
   "lower(t233Ev01.codigoSegurancaCrv) like lower(concat(#{t233Ev01List.t233Ev01.codigoSegurancaCrv},'%'))",
   "lower(t233Ev01.tipoDocCartorio) like lower(concat(#{t233Ev01List.t233Ev01.tipoDocCartorio},'%'))",
   "lower(t233Ev01.numIdentCartorio) like lower(concat(#{t233Ev01List.t233Ev01.numIdentCartorio},'%'))",
   "lower(t233Ev01.numIdentCv) like lower(concat(#{t233Ev01List.t233Ev01.numIdentCv},'%'))",};

 private T233Ev01 t233Ev01;

 public T233Ev01List() {
  t233Ev01 = new T233Ev01();
  t233Ev01.setId(new T233Ev01Id());
  setEjbql(EJBQL);

  setRestrictionExpressionStrings(Arrays.asList(RESTRICTIONS));
  setMaxResults(25);
 }

 public T233Ev01 getT233Ev01() {
  return t233Ev01;
 }
}

例如，当我在表单中填写“Placa Unica”字段时，会生成一个包含所有字段的 sql，如下所示：

SELECT *
  FROM (SELECT t233ev01x0_.idtransacao AS idtransa1_26_,
               t233ev01x0_.dia_juliano AS dia2_26_,

           AND (LOWER (t233ev01x0_.num_ident_cv) LIKE LOWER (? || '%')))
 WHERE ROWNUM <= ?

我不想在查询中输入未填充的字段（空）。我没有找到任何关于“动态限制”的例子，或者用 EntityQuery 做到这一点的另一种方法

卡特诺，这看起来有点像发生在我身上的事情。在我的例子中，有问题的实体是一个视图，而不是一个表，因此 seam/hibernate 找不到用作其 Id 的主键字段。

对于这个视图，seam generate-entities 创建了 2 个实体，一个只包含一个 id，一个包含某种具有所有其他字段的子实体。我真的不明白它做了什么或为什么。我得到的相应 EntityList 看起来很像您在此处发布的那个。

我解决这个问题的方法是在 seam-gen.reveng.xml 文件中明确定义这个实体的主要孩子。该文件位于资源文件夹中。例如，我的 reveng.xml 文件中的条目如下所示：

<table name="office_view">
    <primary-key>
        <key-column name='office_id' />
    </primary-key>
</table>

如果这是您的问题，在此处显式定义主键可能会对您有所帮助。
