After comparing the performance of the common post processor, we also compared the following groovy and BeanShell2 are JVM-based scripting languages, and 2 can use Java syntax and class libraries directlyThese foreign websites are recommended for groovy:Http://jmeter.apache.org/usermanual/best-practices.htmlhttp://www.ubik-ingenierie.com/blog/magento-performance-toolkit-and-jmeter-best-practices/Https://blazemeter.com/blog/beanshell-vs-jsr223-vs-java-

Groovy is a flexible, dynamic language on the Java platform with features like Python, Ruby and Smalltalk, and groovy guarantees that these features are used by Java developers like Java syntax; Here's a simple example of groovy dynamics, a feature I've come into contact with and like, groovy1. In Java, the following JUnit test code executes through int metho

After the storm from blog to mailing list, roadmap of New groovy appeared. To some extent, this is a response to groovy is dead, which has been so popular recently. On the other hand, Mike spille, groovy's neighborhood, responded to the criticism of the New groovy feature in the form of a wiki document. This is the most controversial of all new features, of cour

Many articles in the country are saying that the mixin mechanism of groovy language is the categories mechanism of groovy language. In fact, on the outside of the blog, a large number of people discussing how groovy language should implement its own mixin mechanism, which is that the mixin mechanism of the groovy langu

Groovy tip 32 method parameter 1 The Groovy language has done a lot of useful work in the input parameters of methods. Some of these work can improve the readability of the code, and some can provide convenient and agile coding. In the previous text, we have introduced some of them one after another, such as map and DSL in groovy exploration. In this series, we

When we are working on the Struts2 project, if we update the Java program (here mainly refers to Action), we need to restart Tomcat or Web Context. Such development sometimes affects work efficiency. Every day, there is a lot of time to spend on it. After work, I think of a way to use Groovy as the Struts2 Action. Here, I use Struts2 + Spring + policy1.0 to create a column. First, you need to add a Groovy

Impact of Oracle's acquisition of sun on groovy/grails The first thing we feel is that there should be a good impact. Oracle has long supported the Java platform. This is not an alternative to Oracle, but an inevitable choice as a competitor of Ms. Now it has acquired sun, and there is no reason not to support Java. Therefore, the future of Java is still bright. Oracle has supported groovy/grails as

Recently, when writing a test script in Groovy, a problem occurs. In Groovy 1.5.7, groovy reads a built-in dom Processing Package (org. w3c. dom), and groovy script used in the watij library contains the xml-apis.jar conflict, because the version is not the same.

Groovy's powerful features, Closure,metaclass have tried, Closure basically is when the method or callback interface use, then advanced usage is useless, no special experience what benefits, when callback interface is the province of the defin

Learn how Java next-generation languages reduce boilerplate code and reduce complexity The limitations faced by the Java programming language at birth are different from those faced by today's developers. Specifically, there are primitive types in the Java language due to the performance and memory limitations of hardware in the middle of the 90 's. Since then, the Java language has evolved, with automatic boxing (Autobox) eliminates a lot of hassle, and the next language (

One place where the groovy language is easier to use than the Java language is that the groovy language introduces the operation of the size number. Of course, the number of sizes we're talking about here is that the precision exceeds the float and double decimal. We may have to deal with the size of the number of cases, if it is in the Java language, we can only be or use Java.math.BigDecimal to deal with,

In a previous e-mail, I pointed out that among the many changes, the most obvious is that the development of using other popular languages on the JVM on the Java domain has become more and more rapid. Some old and new-created JVM-based languages---JRuby and Jython, Java-style languages---Groovy and Scala and brand, new languages---Clojure and Kotlin, These languages give us a choice------get the performance and reliability of the JVM but can use a dif

Agreement Groovy Categories and Expandometaclass Groovy contains two different ways to extend an existing class using open classes, and "reopen" a class definition to implement the ability to change, such as adding, changing, or deleting methods. Category class Class classes (a concept that borrows from OBJECTIVE-C) are general classes that contain static methods. Each method takes at least one parame

7.1 defining classes and scripts 7.1.1 defining attributes and declaring attributes of local variables and local variables must be declared before use (except for scripts ), this helps to implement scope rules and prevent programmers from misspelling by mistake. The script allows undeclared variables. In this case, the variables are obtained from the binding attribute of the script. If no corresponding variables are found in the binding, the variables are added to the binding, binding is a data
