Java 绑定aws sqs区域

因此，我尝试使用ApacheCamel访问简单队列服务

JavaDSL方法工作得很好，但我尝试使用xml配置

private AmazonSQS sqs;
sqs = new AmazonSQSClient(credentials);
Region sqsRegion = Region.getRegion(Regions.US_WEST_2);
sqs.setRegion(sqsRegion);

上面的代码运行良好，但我决定构建bean

<context:property-placeholder  location="classpath:/default.properties" />
    <bean name="sqsClient" class="com.amazonaws.services.sqs.AmazonSQSClient">
        <constructor-arg>
            <bean class="com.amazonaws.auth.BasicAWSCredentials">
                <constructor-arg value="${access.key}"/>
                <constructor-arg value="${secret.key}"/>
            </bean>
        </constructor-arg>
        <property name="region" value="com.amazonaws.regions.Region"/>
    </bean>

路由器：

import org.apache.camel.builder.RouteBuilder;
import org.springframework.stereotype.Component;

@Component
public class MyRouteBuilder extends RouteBuilder {

    public void configure() {
        from("aws-sqs://queue?amazonSQSClient=#sqsClient")
                .log("We have a message! ${body}")
                .to("file:target/output?fileName=login-message-${date:now:MMDDyy-HHmmss}.json");
    }
}

以及camel-context.xml

    <?xml version="1.0" encoding="UTF-8"?>

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       ">

    <context:property-placeholder  location="classpath:/default.properties" />

    <bean id="awsRegion" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
        <property name="targetClass" value="com.amazonaws.regions.RegionUtils"/>
        <property name="targetMethod" value="getRegion"/>
        <property name="arguments">
            <list>
                <value>${aws.region}</value>
            </list>
        </property>
    </bean>

    <bean name="sqsClient" class="com.amazonaws.services.sqs.AmazonSQSClient">
        <constructor-arg>
            <bean class="com.amazonaws.auth.BasicAWSCredentials">
                <constructor-arg value="${access.key}"/>
                <constructor-arg value="${secret.key}"/>
            </bean>
        </constructor-arg>
        <property name="region" ref="awsRegion"/>
    </bean>

    <!-- enable Spring @Component scan -->
    <context:component-scan base-package="com.test.router"/>

    <camelContext xmlns="http://camel.apache.org/schema/spring">

        <contextScan/>
    </camelContext>

</beans>

${aws.region}

您的

region

属性的值是字符串值

“com.amazonaws.regions.region”

。它需要一个类型为

com.amazonaws.regions.Region

的对象。因此，您需要引用类型为

Region

的对象，而不是提供字符串值。

假设这个问题

第一:

要向对象添加属性，我只需创建新bean

 <bean id="awsRegion" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
        <property name="targetClass" value="com.amazonaws.regions.RegionUtils"/>
        <property name="targetMethod" value="getRegion"/>
        <property name="arguments">
            <list>
                <value>${aws.region}</value>
            </list>
        </property>
    </bean>

就这些

谢谢重播。我解决了这些问题（查看upd部分），但遇到了另一个问题。我尝试这样做时遇到了一个异常：java.lang.exception:无法转换值org.springframework.beans.factory.config。MethodInvokingFactoryBean@521b30d2键入com.amazonaws.regions.Region
