在我的spring应用程序中,在数据库中插入/更新实体的表单具有与此类似的结构:
<jsp:include page="../../common/cadastrar.jsp">
<jsp:param name="entity" value="Usuario"/>
<jsp:param name="arguments" value="login"/>
<jsp:param name="arguments" value="senha"/>
<jsp:param name="arguments" value="first_name"/>
<jsp:param name="arguments" value="last_name"/>
<jsp:param name="arguments" value="email"/>
</jsp:include>
重定向到此共享jsp页面(所有视图通用):
<c:url value="${param.entity}/cadastra" var="cadastra"/>
<form:form class="form" role="form" method="post" action="${cadastra}">
<table>
<c:forEach var="item" items="${paramValues.arguments}">
<c:choose>
<c:when test="${item == 'senha'}">
<tr>
<td><form:label path="${item}">${item}</form:label></td>
<td><form:input path="${item}" type="password"/></td>
</tr>
</c:when>
<c:otherwise>
<tr>
<td><form:label path="${item}">${item}</form:label></td>
<td><form:input path="${item}"/></td>
</tr>
</c:otherwise>
</c:choose>
</c:forEach>
<tr>
<td colspan="2">
<button type="submit" class="btn btn-lg btn-primary">Cadastrar</button>
</td>
</tr>
</table>
</form:form>
当我的实体类只有原始属性(Integer,String等)时,这段代码工作正常。但我无法弄清楚如何对类似的事情做同样的事情:
@Entity
@Table(name="cliente")
public class Cliente extends Entidade {
@Id
@Column(name = "id")
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Integer id;
@OneToOne
@JoinColumn(name="fk_usuario")
private Usuario usuario;
@Column(name="documento")
private String documento;
@Column(name="cpf")
private String cpf;
@Column(name="cnpj")
private String cnpj;
@ManyToMany
@JoinTable(name="endereco_entrega", joinColumns={@JoinColumn(name="fk_cliente")}, inverseJoinColumns={@JoinColumn(name="fk_endereco")})
@LazyCollection(LazyCollectionOption.FALSE)
private List<Endereco> endereco;
@ManyToMany
@JoinTable(name="pedido_cliente", joinColumns={@JoinColumn(name="fk_cliente")}, inverseJoinColumns={@JoinColumn(name="fk_pedido")})
@LazyCollection(LazyCollectionOption.FALSE)
private List<Pedido> pedido;
}
其中一些属性是其他实体。任何人都可以指出我这样做的方向吗?
