camel route

In the route of camel, messages are transmitted in the form of exchange in each node of route. Therefore, understanding the exchange structure is very important for using camel.If the exchange ID is not specified, camel sets one by default, which can be used to identify an execution of a route.MEP message exchange patt

Camel running example, camel example This is a simple Camel example. The Code is as follows: Public static void main (String [] args) throws Exception {// create the Camel context DefaultCamelContext camelContext = new DefaultCamelContext (); // Add a route with the paramet

Camel-style nomenclature (camel-case), also known as the Hump nomenclature, is a set of naming conventions (conventions) when writing a computer program. As its name CamelCase implies, it means mixing uppercase and lowercase letters to form the names of variables and functions. Programmers in order to their own code can be easier to communicate between peers, so more than a unified readability of the better

Camel-name-utils switches between the camel style and the underline style, and camelbakUsage It is used to switch a string between the camper style and the underline style. It may be useless to the average person, and it may be helpful for the person who writes the orm framework. Example: Company_name-> companyNameAdd the following dependencies to pom. xml for Installation Usage @Testpublic void testCamel2

subsystem provides an integrated environment for Apache Camel and the WildFly application server. It allows you to add a Camel Routes (route) as part of the WildFly configuration. Routes can be deployed as part of a Java EE application. Java EE components can use the core APIs of Camel and multiple

The best way to develop Apache camel applications is TDD, because each component of camel is independent and testable.There are a lot of good test frameworks now, and the BDD (behavioral test Drive) with groovy Spock framework is relatively good and useful.First, we start with the simplest processor.Write Test Cases First:Package Com.github.eric.camelImport Org.apache.camel.ExchangeImport Org.apache.camel.i

app. You can use as many camelcontext as you want, and of course they need to be defined with different names.Wildfly-camel can be defined and deployed in the following 3 different ways: Defined as part of a subsystem in standalone-camel.xml and Domain.xml; In a support for their deployment artifact deployment, of course, this deployment artifact must contain the suffix-camel-context.xml file;

mybatis is managed by Maven, and its Pom. XML content can be viewed by downloading the sub-source code of the column. Springmvc configurations do not need to be pasted out and can be seen everywhere. Here we will focus on some configuration items in the spring and configuration files, especially the following section: Note that the configuration of the last item, through the mybatiscomponent class, camel will know how to interact with mybatis through

Apache camel provides integration with spring and manages camelcontext through the spring container (applicationcontext). In this way, you do not need to write code to control camelcontext initialization, start and stop. camel will be started with spring startup. This article integrates the examples in the Apache camel framework getting started example (http://bl

If the process method returns false, the asynchronous process is complete.D. When the processor finishes processing exchange, it must call the callback. done (boolean sync) method. The sync parameter must be consistent with the return value of the process method.For a

During system integration, an essential task is to convert data from one format to another, and then send the converted format to the target system, here we will introduce how to use freemarker in camel for data conversion. 1. The freemarker template is as follows: 2. The corresponding Java object is as follows: each person node corresponds to a valueobject placed in the peoplelist of xmltemplateparameter. public class XMLTemplateParameter { priva
