JSF 2注入的Spring bean / @ManagedProperty与无XML服务 [英] JSF 2 inject Spring bean/service with @ManagedProperty and no xml

问题描述

我想用JSF注释和一些春天
注释注入一个Spring bean /服务为一体的JSF托管bean。
（在JSF豆我只想使用JSF的注解）
我不想使用像 @Named / @Inject 注释。

I would like to use jsf annotations and some spring annotations to inject a spring bean/service into a jsf managed bean. (on the jsf bean i only want to use jsf annotations) I dont want to use annotations like @named / @inject.

我试图在网络上找到，但没有任何运气的解决方案。

I have tried to find a solution on the net but without any luck.

示例

@ManagedBean
@ViewScoped 
public class MyBean {

    @ManagedProperty(value = "#{mySpringBean}")
    private MySpringBean mySpringBean;

    public void setMySpringBean(MySpringBean mySpringBean) {
        this.mySpringBean = mySpringBean;
    }

    public void doSomething() {
    //do something with mySpringBean
    }
}

是这样的事情可以不使用XML。例如，
我不喜欢用类似

Is something like this possible without the use of xml. For example, I would NOT like to use something like

FacesContextUtils.getWebApplicationContext(context).getBean("MySpringBean");

或 faces-config.xml中

<managed-bean>
    <managed-bean-name>myBean</managed-bean-name>
    <managed-bean-class>com.mytest.MyBean</managed-bean-class>
    <managed-bean-scope>view</managed-bean-scope>
    <managed-property>
        <property-name>mySpringBean</property-name>
        <value>#{mySpringBean}</value>
    </managed-property>
</managed-bean>

是一样的东西上面可能有注释和无
定义所有的JSF豆/属性和春天豆/性能
在配置XML文件中每个bean？

Is something like the above possible with annotations and without defining all the jsf beans/properties and the spring beans/properties for every bean in the config xml files?

推荐答案

如果你已经有了Spring容器，为什么不使用它的@Autowired注解。为此，更新faces-config.xml中通过博尼的建议。在此之后，这些听众，然后添加到您的web.xml

If you already have Spring container why not use its @Autowired annotation. For that, Update your faces-config.xml as suggested by Boni. Then add these listeners to your web.xml after this

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>

<listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<listener>
  <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
</listener>

然后将这些添加到你的applicationContext.xml

Then add these to your applicationContext.xml

<context:component-scan base-package="com.examples" />

现在你可以使用Spring的注解，你的bean将是这样的：

Now you can use Spring annotations and your bean will be something like this:

package com.examples;
@Component
@Scope(value="request")
public class MyBean {
    @Autowired
    private MySpringBeanClass mySpringBean;
}

与@Service标注您MySpringBeanClass

Annotate your MySpringBeanClass with @Service

另请参见：

• @Scope("request")不工作

• @Scope("request") not working
