SEAM ENTITYQUERY - 有限制seam-gem示例的問題

Question

我的項目最初是由seam-gen生成的，動作「List」bean沒有按照我的預期工作。限制數組具有來自表的所有屬性，並且表現得像所有參數都是必需的。在列表中看到婁：

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; 
} 
} 

當我只需填寫表格，例如現場「加泰羅尼亞總聯合會」，都是這樣產生的所有字段的SQL：

     WHERE (LOWER (t233ev01x0_.renavam) LIKE LOWER (? || '%')) 
      AND (LOWER (t233ev01x0_.ano_fabricacao) LIKE LOWER (? || '%')) 
      AND (LOWER (t233ev01x0_.ano_modelo) LIKE LOWER (? || '%'))

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

我不想放入查詢中，未填充的字段（空）。我沒有找到任何關於「動態限制」的例子，或者使用EntityQuery來做到這一點。

Answer 1

Cateno，這看起來像是發生在我身上的事情。在我的情況下，有問題的實體是一個視圖，而不是一張表，因此seam/hibernate找不到主鍵字段作爲其ID。

對於這個視圖，seam generate-entities創建了2個實體，一個只包含一個id，另一個包含某種子實體和其他所有字段。我真的不明白它做了什麼或爲什麼。我收到的相應實體清單看起來像你在這裏發佈的那個。

我解決這個問題的方法是在seam-gen.reveng.xml文件中明確定義此實體的主要孩子。該文件位於資源文件夾中。對於這裏的例子就是在我reveng.xml文件中的條目看起來像：

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

如果這是你的問題，明確地定義一個主鍵在這裏可以幫助你。
