问题 Is Eventbus more a Mediator or an Observer? According to Google, "eventbus mediator" gets 2.430 hits and "eventbus observer" gets 3.850 hits. From the description, they would both match what I was trying to do (the mediator even a little more). So does eventbus implement a specific pattern or is it up to me which I say it is? 回答1: Often, a given piece of code isn't intrinsically an example of one pattern or another. This is why they're called "patterns" (rather than, say, "implementation

问题 As it says in the documentation of the DBLookup Mediator it only returns the first row of the query, the other results if they are, were ignored. I want to know if there is a "best way" to run a query (SELECT * FROM X) that return multiple records and then process them. Now a days we are doing that implementing axis2 services but there is another way using a combination of the mediators provided by wso2 esb to accomplished that requirement?? Thanks in advance. Santiago. 回答1: Yes DBlookup

问题 I've been experimenting with the mediator pattern and CQRS using the MediatR library in a WinForms application that uses the Entity Framework for data access. The application is used in a batch manufacturing plant, and allows users to see a list of active and completed batches, and if necessary make updates to batch information. Each batch has a large amount of information associated with it, such as quality and process measurements. Reading and writing data is organized into Queries and

问题 I am working with a filter mediator attempting to send messages to an output xml file. I have my sequence using a filter mediator based on a attribute value, if it is true I want to write the message to a new xml file in a certain directory. If it is false I will drop the record. Here is my sequence: <sequence xmlns="http://ws.apache.org/ns/synapse" name="RenaissanceIqtFilterSequence"> <log level="custom"> <property name="sequence" value="FilterSequence"></property> </log> <filter xmlns:rs=

问题 I receive a message from AAA nested children. I want every child BBB replace the value of CCC .

问题 Ok, this is a continuation to my original question. (WSo2 Esb filtering messages to an output file) After a couple more days of research into the iterate and aggregate mediator I have reached a progress wall and would be very grateful for any advice how to resolve my blocking issue. The task at hand is simple, read and xml file, filter on certain records, and only produce an output xml file with just those records that meet the criteria. After previous discussion and research this tasks

问题 im facing up to wso2 ESB 4.8.1 and WSO2 GREG 4.6.0. I have connected GREG as esb's remote Registry and now i need to develop a class mediator by which i can store shared recources inside the remote registry. 1) Does the Registry can store Java Object? 2) should i use org.apache.synapse.registry.Registry for browing the registry? or is it better to import the governance api inside the mediator project? For example i need to add and get a resource and to set it my custom properties. Then i want

问题 I'm trying to use a Script Mediator in WSO2 that has the following definition: <script xmlns="http://ws.apache.org/ns/synapse" language="py" key="myPythonScript" function="process"/> I had to hard-code the "py" as language since Javascript, Ruby, and Groovy were the only options available in the language drop down list, although the WSO2 ScriptMediator documentation states that Python is supported. When I try to save my proxy changes I get the error "ERROR - ScriptMediator No script engine

问题 Ways to Implement Dependency Inversion Principle in AngularJS Case Study: The Mediator Pattern Normally, implementing a Mediator/Director entails both Director and Colleague(s) having a reference to each other. Not difficult when Director is responsible for Module-Lifecycle Management (MLM) : Director creates Colleagues while passing itself in during construction: var Director = function Director($$) { ... function init(...) { _moduleA = new ModuleA(this); _moduleB = new ModuleX(this);
