使用注释指定spring bean(Assign spring beans with annotations)

使用注释指定spring bean(Assign spring beans with annotations)

我是新的注释，我正在尝试jsf（2.0）spring（3.1）集成，我可以集成两个framewoks但我没有JSF中的viewScope，因为它不可用。 我想使用注释在jsf managedBean中自动注入spring bean，但我不能因为Spring只支持会话并请求范围bean。

我使用一个Util类来检索bean。 “SprigUtil.getBean（ '豆'）”。 并在我需要时手动退回春豆。

我想做这样的事

@CustomAnnotation（'beanTest'）私有Bean bean;

因此，将使用beanTest bean设置bean Atributte。

我的目标（抛开春天）知道如何做这样的事情

@assing（'House'）私人弦乐场所;

当我调用getMethod获取“House”时。 instance.getPlace（），返回'House'

注意：我知道@Autowired但我无法使用它，因为在spring-jsf集成中ViewScope不可用。 我读到了关于手动实现视图范围但是想要尝试不同的解决方案。

还有我的appContext

我的春豆

@Component public class ProductService{ }

我的托管豆

@Component @Scope("request")//I need to use @Scope("view") but it doesn't exist public ProductBean implements Serializable{ @Autowired ProductService productoService; }

如果我使用jsf注释@ManagedBean并且@ViewScoped没有注入productService（为null）

I'm new with annotations, I'm trying the jsf(2.0) spring (3.1) integration, I could integrate the two framewoks but I don't have the viewScope in JSF beacause it isn't avaliable. I want to use annotations to inject automatically spring beans in the jsf managedBean, but I can't becauso Spring only suppor sessions and request scope beans.

I use a Util class who retrives the bean. "SprigUtil.getBean('bean')". And manually retirve spring beans when I need.

I want to do some like this

@CustomAnnotation('beanTest') private Bean bean;

So, the bean Atributte will be set with the beanTest bean.

My objective (leaving aside spring) is know how to do some like this

@assing('House') private String place;

and when I call the getMethod obtain "House". instance.getPlace(), return 'House'

Note: I Know about the @Autowired but I can't use that because ViewScope is not avaliable in spring-jsf integration. I read about implement the view scope manually but a want to try a different solution.

Edit:

My FacesConfig:

My FacesConfig:

<?xml version="1.0" encoding="UTF-8"?> <faces-config xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_1.xsd" version="2.1"> <application> <el-resolver> org.springframework.web.jsf.el.SpringBeanFacesELResolver </el-resolver> </application> </faces-config>

And my appContext

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd"> <context:component-scan base-package="*" /> </beans>

My Spring bean

@Component public class ProductService{ }

My Managed Bean

@Component @Scope("request")//I need to use @Scope("view") but it doesn't exist public ProductBean implements Serializable{ @Autowired ProductService productoService; }

If I use the jsf annotations @ManagedBean and @ViewScoped productService is not injected (is null)

最满意答案

您可以使用@ManagedProperty将spring bean注入视图范围的托管bean

对于名为B的弹簧组件

@ManagedProperty("#{B}") private B b; public void setB(B b) { this.b = b; }

应该管用。

至于你发布的代码，Component是一个Spring注释，要使用ViewScoped，你必须用ManagedBean注释注释你的类：

@ManagedBean @ViewScoped public ProductBean implements Serializable { @ManagedProperty("#{productService}") private ProductService productService; public void setProductService(ProductService productService) { this.productService = productService; } }

您可能需要查看以下链接以更好地了解JSF 2.0中JSF 2.0 通信的范围

You can inject spring beans into view scoped managed beans by using @ManagedProperty

For a spring component named B

@ManagedProperty("#{B}") private B b; public void setB(B b) { this.b = b; }

should work.

As for the code you have posted, Component is a Spring annotation, to use ViewScoped you must annotate your class with the ManagedBean annotation:

@ManagedBean @ViewScoped public ProductBean implements Serializable { @ManagedProperty("#{productService}") private ProductService productService; public void setProductService(ProductService productService) { this.productService = productService; } }
