Facelet标题
getlisteneesannemetier私有对象的方法，该方法尚未初始化。您可以通过setAnneMetier
方法初始化该对象，该方法从未在代码中初始化过，因此它是null
。您可以通过执行以下操作之一来解决问题：
在使用getListenees
您为您的AnneeBean
类实现了一个构造函数，在该类中初始化anneetemier
您可以将getter（getListenes
）修改为如下所示：
public List getlistenees（）{
如果（AnneMetier==null）{
返回新的ArrayList（）；
}
listenenes=annemetier.getAllAnnees（）；
回归李斯特尼斯；
}
编辑：pL4GU33的评论可能很有用，因此我在答案中添加了他的评论：
public List getlistenees（）{
如果（AnneMetier==null）{
返回集合。emptyList（）；
}
listenenes=annemetier.getAllAnnees（）；
回归李斯特尼斯；
}
他的解决方案更不区分类型，所以我支持他的评论。对于非JSF开发人员来说，最简单的解决方案是初始化getter中的变量，以解析属性中的null
值。这是：
public List getListeAnnees() {
listeAnnees = getAnneeMetier().getAllAnnees();
return listeAnnees;
}
public AnneeMetier getAnneeMetier() {
if (anneeMetier == null) {
anneeMetier = new AnneeMetierImpl();
}
return anneeMetier;
}
但是，如果annemetier#getAllAnnees（）
从数据库检索数据，这可能会从服务器上产生大量开销。这里解释如下：
要解决这个问题，您需要做两件事：
使用@PostConstruct
带注释的方法初始化工作所需的数据
这将导致：
将范围定义为@ViewScoped
（在上面的链接中解释）
在@PostConstruct
方法中初始化列表项
从getter/setter中删除任何业务逻辑
因此，代码如下所示：
@ManagedBean
@ViewScoped
public class AnneeBean {
private AnneeMetier anneeMetier;
private List<Annee> listeAnnees;
@PostConstruct
public void init() {
anneeMetier = new AnneeMetierImpl();
listeAnnees = anneeMetier.getAllAnnees();
}
public List getListeAnnees() {
return listeAnnees;
}
public void setListeAnnees(List listeAnnees) {
this.listeAnnees = listeAnnees;
}
public AnneeMetier getAnneeMetier() {
return anneeMetier;
}
public void setAnneeMetier(AnneeMetier anneeMetier) {
this.anneeMetier = anneeMetier;
}
}
@Component
@Scope("view")
public class AnneeBean {
@Autowired
private AnneeMetier anneeMetier;
private List<Annee> listeAnnees;
@PostConstruct
public void init() {
listeAnnees = anneeMetier.getAllAnnees();
}
public List getListeAnnees() {
return listeAnnees;
}
public void setListeAnnees(List listeAnnees) {
this.listeAnnees = listeAnnees;
}
}
更多信息：
因为您正在学习Spring，所以最好启用组件扫描并使用注释来配置Springbean。请执行以下操作：
- 删除applicationContext.xml中的任何bean配置
- 添加此配置以启用bean扫描注释：
@Repository
public class AnneeHibernateDao implements AnneeDao{
//...
}
@Service
public class AnneeMetierImpl implements AnneeMetier{
@Autowired
private AnneeDao anneeDao;
//...
}
或者如果所有类都在一个根包中
<!--
Assuming there's a root package for your packages like this
<context:component-scan base-package="com.myproject.dao" />
<context:component-scan base-package="com.myproject.model.services" />
-->
<context:component-scan base-package="com.myproject" />
编译您的项目并运行它。在index.xhtml中，我调用bean AnneeBean.java公共列表getListenees（）中的方法getListanees（）{listenees=annemetier.getAllanees（）；//这里我调用spring方法return listenees；}它看起来像是“annemetier”在AnneeBean.getListenees中为null。您应该在初始化时为其设置一个空列表或进行空检查。对于3，我更希望返回集合。emptyList（）。如果您以前使用过JSF 2，您会知道这不是正确的解决方案，而不是使用新的ArrayList（）。@LuiggiMendoza，您能详细说明您的意见吗？这些建议有什么问题吗？请阅读此处：。因为bean是请求范围的，所以这样做意味着在每个请求上从数据库检索对象（IMO不希望这样）。这是事实，而且确实是不可取的，但是，问题是关于有一个NullPointerException，而不是最小化请求数。因此，您的观点是正确的，但我不确定我们是否在修复NullPointerException之前优化了op的方法，从而帮助了op。另外，在频繁插入、更新和删除的情况下，从每个请求的数据库中获取资源可能很有用now@Marina奇怪的是，您的spring应用程序context.xml中没有启用上下文。您使用的是哪个版本的Spring？我使用的是Spring 3.1.1.Release请检查如何在项目中启用组件扫描。如果这不起作用，请在project ag中手动配置每个Springbean
