問題描述

我想使用 jsf 注釋和一些 spring將 spring bean/服務(wù)注入 jsf 托管 bean 的注釋.(在 jsf bean 上我只想使用 jsf 注釋)我不想使用像 @named/@inject 這樣的注解.

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.

我試圖在網(wǎng)上找到解決方案，但沒有任何運(yùn)氣.

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

例子

@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
    }
}

在不使用 xml 的情況下，這樣的事情是否可行.例如，我不想使用類似的東西

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");

或在 faces-config.xml

<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>

上面的內(nèi)容是否可能有注釋和沒有注釋定義所有 jsf beans/properties 和 spring beans/properties配置 xml 文件中的每個 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?

推薦答案

如果你已經(jīng)有了 Spring 容器，為什么不使用它的 @Autowired 注解.為此，請按照 Boni 的建議更新您的 faces-config.xml.然后在此之后將這些偵聽器添加到您的 web.xml 中

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>

然后將這些添加到您的 applicationContext.xml

Then add these to your applicationContext.xml

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

現(xiàn)在您可以使用 Spring 注釋，您的 bean 將是這樣的:

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;
}

使用 @Service 注釋您的 MySpringBeanClass

Annotate your MySpringBeanClass with @Service

另見:

• @Scope("request") 不起作用
