我创建了带有两个PropertyPlaceholderConfigurer Bean的applicationContext,并且仅根据基于上下文对象的输入访问了一个。但是,当从“ Service2Record”实例访问属性时,我正在获取“ Service1Record”属性值。下面是我的示例代码。

ApplicationContext.xml

<beans >

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

<!-- Service1 Properties files -->
<bean id="service1"
    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="ignoreUnresolvablePlaceholders" value="true"/>
    <property name="locations" >
        <value>classpath:service_1.properties</value>
    </property>
    <property name="properties" >
        <value>service1.class=com.test.record.ServiceRecord</value>
    </property>
</bean>
<bean id="service1record" class="${service1.class}" />

<!-- Service2 Properties files -->
<bean id="service2"
    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="ignoreUnresolvablePlaceholders" value="true"/>
    <property name="locations">
        <value>classpath:service_2.properties</value>
    </property>
    <property name="properties">
        <value>service2.class=com.test.record.ServiceRecord</value>
    </property>
</bean>
<bean id="service2record" class="${service2.class}" />




ServiceRecord Bean:-

@Configuration


公共类ServiceRecord {

@Value("${request_queue_name}")
private String requestQueueName;

@Value("${reply_queue_name}")
private String replyQueueName;

public String getRequestQueueName() {
    return requestQueueName;
}

public String getReplyQueueName() {
    return replyQueueName;
}


}

测试主要课程-

public static void main(String[] args) {
    ApplicationContext context = new ClassPathXmlApplicationContext(
            "classpath:applicationContext.xml");
    ServiceRecord serviceRecord = null;
    String inputService = "SERVICE2";
    if(inputService.equals("SERVICE1")){
        serviceRecord = (ServiceRecord)context.getBean("service1record");
    } else {
        serviceRecord = (ServiceRecord)context.getBean("service2record");
    }
    System.out.println(" RequestQueueName : " + serviceRecord.getRequestQueueName());

}




service_1.properties

request_queue_name=SERVICE1.REQUEST


reply_queue_name = SERVICE1.REPLY

service_2.properties

request_queue_name=SERVICE2.REQUEST


reply_queue_name = SERVICE2.REPLY

在此,每次输出为“ RequestQueueName:SERVICE2.REQUEST”。您能否告诉您如何基于属性文件获取相应的值?

修改-

我有一个PPHC,在其中为location属性设置了多个prop文件,并为多个propertieArray设置了如下。

<property name="locations">
            <list>
                <value>classpath:common-service.properties</value>
                <value>classpath:search-service.properties</value>
                <value>classpath:update-service.properties</value>
            </list>
        </property>
        <property name="propertiesArray" >
            <list>
                <value>common.class=com.xyz.rabbitmq.record.CommonUtil</value>
                <value>search.class=com.xyz.rabbitmq.record.SearchRecord</value>
                <value>update.class=com.xyz.rabbitmq.record.UpdateRecord</value>
            </list>
        </property>

    <bean id="commonrecord" class="${common.class}"/>
<bean id="searchrecord" class="${search.class}"/>
<bean id="updaterecord" class="${update.class}"/>


在这里,每个属性文件中的键都不同,并且根据搜索或更新请求类型来获取Bean实例。

serviceRecord =(ServiceRecord)context.getBean(“ searchrecord”);

这种方法是否适合加载不同的文件?

最佳答案

我建议您在属性文件中使用不同的键:

service_1.properties

service1.request_queue_name=SERVICE1.REQUEST
service1.reply_queue_name=SERVICE1.REPLY


service_2.properties

service1.request_queue_name=SERVICE2.REQUEST
service1.reply_queue_name=SERVICE2.REPLY


而不同的ServiceRecord文件ServiceRecord1.java ServiceRecord2.java每个都从相关属性文件中读取属性。即,当添加新的属性集/文件时,您需要添加新的ServiceRecord文件。

如果您不想有多个ServiceRecord,则可以改用Util方法..

public String getProperty(String serviceName, String propertyName) {
    return propertySource.getProperty(serviceName+"."+propertyName);
}
