本文介绍了整合jsf，spring，hibernate。如何将Spring bean注入到JSF托管的bean中？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在使用框架JSF 2.1，Spring 3.1.1.Release，hibernate 3.2.1开发Java EE项目。现在我正处于整合他们三个的阶段。
构建成功，我使用tomcat服务器7，但是我在头版获得这个异常。

解决方案
非JSF开发者的天真解决方案是只需初始化getter中的变量即可解决属性中的 null 值。这是： 
 
 
  public List getListeAnnees（）{
 listeAnnees = getAnneeMetier（）。getAllAnnees（）; 
返回listeAnnees; 
} 
 
 public AnneeMetier getAnneeMetier（）{
 if（anneeMetier == null）{
 anneeMetier = new AnneeMetierImpl（）; 
} 
 return anneeMetier; 
} 
  
但是，如果 AnneeMetier＃getAllAnnees（）从数据库中检索数据。这在这里解释：为什么JSF多次调用getters  
 
 
 为了解决这个问题，你需要做两件事： 
 
 
 
  定义bean的正确范围。
 
 使用 @PostConstruct 注释方法为工作初始化必要的数据。 / li> 
 
这会导致： 
 
  
 将范围定义为 @ViewScoped （在上面的链接中解释过）
 
 初始化 listeAnenees  @PostConstruct 方法。
 
从getters / setters中删除任何业务逻辑
 
 ol> 
 
 所以代码如下所示： 
 
 
  @ManagedBean 
 @ViewScoped 
 public class AnneeBean {
 private AnneeMetier anneeMetier; 
私人列表< Annee> listeAnnees; 
 
 @PostConstruct 
 public void init（）{
 anneeMetier = new AnneeMetierImpl（）; 
 listeAnnees = anneeMetier.getAllAnnees（）; 
} 
 
 public List getListeAnnees（）{
 return listeAnnees; 
} 
 
 public void setListeAnnees（List listeAnenees）{
 this.listeAnnees = listeAnenees; 
} 
 
 public AnneeMetier getAnneeMetier（）{
 return anneeMetier; 
} 
 
 public void setAnneeMetier（AnneeMetier anneeMetier）{
 this.anneeMetier = anneeMetier; 
 
 
   但重新尝试将JSF与Spring集成，您必须考虑到 Spring尚未完全支持JSF 2  @ViewScoped 注释。对于这种情况，您需要自己实施。网上有很多关于这方面的例子，看起来最受欢迎的是来自 Cagatay的。这样，你就可以从双方获得权力。您的bean看起来像这样： 
 
 
  @Component 
 @Scope（view）
 public AnneeBean类{
 @Autowired 
私人AnneeMetier anneeMetier; 
私人列表< Annee> listeAnnees; 
 
 @PostConstruct 
 public void init（）{
 listeAnnees = anneeMetier.getAllAnnees（）; 
} 
 
 public List getListeAnnees（）{
 return listeAnnees; 
} 
 
 public void setListeAnnees（List listeAnenees）{
 this.listeAnnees = listeAnenees; 
 
 
 $ / code $ / pre 
 
更多信息 
 
  
   Bean属性在不同的会话中共享 
 
 
 
 
 由于您正在学习Spring，所以最好的办法是启用组件扫描并使用注释来配置你的春豆。执行以下操作：
 
 
 
 删除applicationContext.xml中的任何bean配置。
 
  添加这个配置可以启用bean扫描注释： 
 
 
 <！ -  
这些将会使用批注配置
启用组件扫描，而不是使用XML配置。每包一个
  - > 
< context：component-scan base-package =dao/> 
< context：component-scan base-package =model.services/> 
  
或者如果所有的类都在一个根包中。
 <！ -  
假设您的软件包有一个根包，例如
< context：component-scan base-package =com .myproject.dao/> 
< context：component-scan base-package =com.myproject.model.services/> 
  - > 
< context：component-scan base-package =com.myproject/> 
  
 
 
  开始配置您的Spring托管bean：
  @Repository 
 public class AnneeHibernateDao implements AnneeDao {
 // ... 
} 
 
 @服务
 public class AnneeMetierImpl实现AnneeMetier {
 @Autowired 
私有AnneeDao anneeDao; 
 // ... 
} 
  
 
 
 
 
 
 编译您的项目并运行它。

 解决方案 
The naive solution for non-JSF developers would be to simply initialize the variables inside the getter to resolve the null value in the attributes. This is:
public List getListeAnnees() {
    listeAnnees = getAnneeMetier().getAllAnnees();
    return listeAnnees;
}

public AnneeMetier getAnneeMetier() {
    if (anneeMetier == null) {
        anneeMetier = new AnneeMetierImpl();
    }
    return anneeMetier;
}
But this may generate lot of overhead from server in case AnneeMetier#getAllAnnees() retrieves the data from database. This is explained here: Why JSF calls getters multiple times

To solve this, you do two things:

Define the right scope of your bean.
Initialize the necessary data for work using @PostConstruct annotated method.
And this would result in:

Defining the scope as @ViewScoped (explained in the link above).
Initializing listeAnnees in @PostConstruct method.
Remove any business logic from getters/setters
So the code would look like this:
@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;
    }
}
BUT since you're trying to integrate JSF with Spring, you have to take into account that Spring has not yet full support of JSF 2 @ViewScoped annotation. For this case, you have/need to implement it yourself. There are plenty examples on the net about this, and looks that the most popular is from Cagatay's. In this way, you'll be able to gain power from both sides. And your bean will look like this:
@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;
    }
}
More info:


Bean properties are shared across different sessions




Since you're learning Spring, the best bet would be to enable component scan and use annotations to configure your spring beans. Do the following:


Remove any bean configuration in applicationContext.xml.
Add this configuration to enable bean scan annotations:
<!-- 
    These will enable component scan by annotation configuration
    rather than XML configuration. One per package
-->
<context:component-scan base-package="dao" />
<context:component-scan base-package="model.services" />
Or if all your classes are inside one root package.
<!--
    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" />

Start configuring your Spring managed beans by annotations:
@Repository
public class AnneeHibernateDao implements AnneeDao{
    //...
}

@Service
public class AnneeMetierImpl implements AnneeMetier{
    @Autowired
    private AnneeDao anneeDao;
    //...
}



Compile your project and run it.
