使用带有WSO2 ESB的类介体

Question

我正在尝试使用WSO2 ESB的类中介.

以下是我的调解员课程.

package samples.mediators;

import org.apache.synapse.MessageContext;
import org.apache.synapse.mediators.AbstractMediator;

public class SiriBankMediator extends AbstractMediator {
    @Override
    public boolean mediate(MessageContext messageContext) {
        System.out.println("Hurraaaayyyy!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!");
        return false; 
    }
}

正如编写WSO2 ESB Mediator所建议的那样,我尝试了"更简单的方法",创建了一个包含在类路径中的synapse-core_2.1.0.wso2v8.jar的jar.

MANIFEST.MF如下

Manifest-Version: 1.0
Class-Path: synapse-core_2.1.0.wso2v8.jar
Created-By: 1.7.0_07 (Oracle Corporation)

然后在文章建议中,将jar放到ESB中的repository/components/lib中.

但是当我尝试加载类 ESB重启后,它会在路径中找不到错误类

使用的Jar文件在siri.jar中共享

不知道我遵循的步骤中缺少什么.

先感谢您.

注意:我使用的是WSO2 Enterprise Service Bus 4.5.1

我已经使用maven方法成功部署了您的自定义中介.这就是我所做的.

我创建了以下目录结构,并将您的SiriBankMediator.java放在src/main/java中:

.
??? pom.xml
??? src
?   ??? main
?       ??? java
?           ??? SiriBankMediator.java

pom.xml文件如下:

<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

            <version>1.3.0.wso2v1</version>
        </dependency>
    </dependencies>
</project>

然后在包含POM文件的目录中,我们这样做mvn compile package.这应该构建您需要放在$ESB_HOME/repository/components/lib名为target的文件夹中的jar文件.

最后,您可以通过碳管理前端将类加载为org.samples.mediator.SiriBankMediator.不要忘记重新启动ESB.希望有所帮助.:)
