在我当前的spring项目中，当我运行应用程序并使用以下代码打开视图时：
<form:select path="${entry.key}" class="form-control">
<c:forEach var="option" items="${values[entry.key]}">
<form:option value="${option.id}" label="${option.nome}" class="form-control"/>
</c:forEach>
</form:select>
或
<c:forEach var="option" items="${values[entry.key]}">
<form:checkbox path="${entry.key}" value="${option.id}" label="${option.nome}" class="form-control"/>
</c:forEach>
我收到错误：

任何人都可以告诉我应该向依赖项中添加哪些库以允许我解决此错误？
更新
在sugestions之后，我向我的pom.xml添加了依赖spring-core。首先，我添加版本4.0.6，这不解决我的问题。如果我尝试添加版本3.2.9，由于版本与我的应用程序中添加的其他库的冲突，我甚至无法构建应用程序。
因为这个，我现在正在寻找一个解决方案，使用标签form:select（以及导致相同错误的form:checkbox）与我正在使用的弹簧版本。下面是一些与此问题相关的代码：
values的方法。Pagina.java
@Entity
@Table(name="pagina")
public class Pagina {
@Id
@Column(name = "id")
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Integer id;
@Column(name = "nome", unique=true)
@Order(value=1)
private String nome;
@Column(name = "titulo")
@Order(value=2)
private String titulo;
@Column(name="resumo", length=140)
@Order(value=3)
private String resumo;
@Column(name = "descricao", length=65535)
@Order(value=4)
private String descricao;
@OneToOne( fetch = FetchType.EAGER )
@Order(value=5)
@JoinColumn(name="parent_page")
private Pagina pagina;
@OneToOne( fetch = FetchType.EAGER )
@JoinColumn(name="parent_product")
@Order(value=6)
private Produto produto;

您可以看到旧版本的 Spring WS 和 Spring Security 也提取了一些旧的 Spring Framework 依赖项。我强烈建议将<dependencyManagement>部分添加到您的POM中并强制这些依赖项为4.0.3：
