java - 如何在 Spring+JSF 应用程序中使用 JSF 注解

Question

我想在 JSF ManagedBean 中注入(inject) spring bean。现在我用:applicationContext.xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans     
        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-3.0.xsd">

    <bean id="service" class="com.evgeny.domain.TestService"></bean>

</beans>

face-config.xml:

<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_0.xsd"
    version="2.0">

    <application>
        <el-resolver>
            org.springframework.web.jsf.el.SpringBeanFacesELResolver
        </el-resolver>
    </application>

    <managed-bean>
        <managed-bean-name>facesBean</managed-bean-name>
        <managed-bean-class>com.evgeny.jsf.FacesBean</managed-bean-class>
        <managed-bean-scope>session</managed-bean-scope>
        <managed-property>
            <property-name>service</property-name>
            <value>#{service}</value>
        </managed-property>
    </managed-bean>

</faces-config>

...并且它有效。但我想对 JSF bean 使用注释。那么如何在@ManagedBean注解的bean中注入(inject)TestService呢？

Answer 1

您可以使用@ManagedProperty

通过注入(inject)

@ManagedProperty(value="#{testService}")
private TestService testService;

像使用注释一样定义服务实现

@Service(value = "testService")
public class TestServiceImpl implements TestService

当您在 xml 文件中定义了 bean 时，您可以用该 bean id 替换 @ManagedProperty 注入(inject)中的值

希望这有帮助!!!!
