Question

我有一个Apache camel应用程序，其中camel-config文件中有一个占位符。如果设置我的环境变量，它在Windows机器中可以很好地运行。但这在Mac中不起作用

这是针对具有apache camel版本2.16和spring 4的Java中间件应用程序。我试图在.bash_profile中包括环境变量。当我执行printenv时，显示的值对应于键

这是我的camel-config.xml中的占位符

<bean id = "ICM_HIERARCHY_PROCESSOR" class="p4p.processors.ICMHierarchyProcessor"/>
<bean id = "ICM_PAYMENT_FILE_PROCESSOR" class="p4p.processors.ICMPaymentFileProcessor"/>
<bean id = "INCENTIVE_PROCESSOR" class="p4p.processors.PerformanceProcessor"/>
<bean id = "EMAIL_ALERT_PROCESSOR" class="p4p.processors.EmailAlertProcessor" />
<bean id = "ADM_PROCESSOR" class="p4p.processors.ADMProcessor"/>
<bean id = "ADP_PROCESSOR" class="p4p.processors.ADPProcessor"/>
<bean id = "ADP_CONTROL_PROCESSOR" class="p4p.processors.ADPControlProcessor"/>
<bean id = "HR_PROCESSOR" class="p4p.processors.HRProcessor"/>

<context:property-placeholder location="classpath*:application-${EPAAS_ENV}.properties" ignore-unresolvable="true" order="0"/>

<bean id="loginInfo" class="java.util.HashMap">
    <constructor-arg>
        <map key-type="java.lang.String" value-type="java.lang.String">
            <entry key = "username" value="${p4p.admin.username}"/>
            <entry key = "password" value="${p4p.admin.password}"/>
            <entry key = "encryptKey" value="${p4p.juice.key}"/>
        </map>
    </constructor-arg>
</bean>

application.properties文件：

camel.springboot.name = p4p-central-dispatch-camel

# properties used in the Camel route and beans
# --------------------------------------------

p4p.envName = ${EPAAS_ENV}

使用文件的示例：

@Component
public class EmailAlertProcessor implements Processor {

    @Value("${p4p.envName}")
    private String envString;

    @Override
    public void process(Exchange exchange) throws Exception {
        String fileName = exchange.getIn().getHeader("CamelFileName", String.class);

        exchange.getIn().setHeader("subject", "[ePaaS:POA] File Uploaded from " + envString);
        exchange.getIn().setBody("[ePaaS]File Uploaded: " + fileName + "\nUpload Time:" + new Date());
    }
}

启动服务器时出现此错误

但是epaas_env的值为E1，它在执行命令printenv后正在打印

骆驼配置文件无法读取MacOS中的环境变量
