Direct hit scene I remember the first contact with the computer, I was affected by two very large misconceptions, the concept was originally from the teacher's teaching or the teachings of the seniors have not been remembered, but until I worked a few years later, only slowly have a practical experience: Learning and using what programming language is not important, is the algorithm and design; The essence of programmer learning is the object-oriented design pattern, after m

This is my colleague, in the case of extremely poor documentation, to pay tribute to what stones out. 1.Groovy Current development status groovy has been released as scheduled the last one is a version of the classic parser-beta10, the future version will be based on the JSR standard parser, is expected to send three JSR version, one per month, in the year may have a formal version out.

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

Groovy 1.6 introduces call site optimization. Call site optimization is actually the cache of method selection. Method selection In a static language (such as Java), the binding of a method call is done at compile time (not exactly, such as a virtual function, but in general, the method invocation of a static language is very efficient). In a dynamic language such as groovy, the method invoked is selected

Groovy language is most proud of the characteristics of the DSL, the definition of DSL and classification, advantages, etc., it is not to be elaborated in this article, you can access the Internet, there is a large number of this convenient introduction. The groovy language is a great way to design your internal DSL, and in this context, my Groovy Discovery serie

Scala"", "Sans-serif" '> and groovy are both JVM-based languages, which have more concise syntax and rich expression capabilities than Java. Scala and groovy are good choices for developers who want to avoid tedious Java statements without leaving the JVM. But which one can take the lead in the future development process? Which one is the future development direction? These are problems that plague develope

STEP1: Configuring the JDK Groovy is Java-dependent, so you need to configure the JDK first. Step2: Download Groovy Download the address, download it and unzip it.STEP3: Configuring Groovy Environment Variables Create a new groovy_home with a value of the path you just unzipped. Modify path, append%groovy_home%\bin at the endSTEP4: Testing On the command lin

Use GVM to build the Groovy development environment and third-party jar package path Configuration Recently I need to write a small program in Groovy, so I will download a policyat http://policy.codehaus.org. In this process, we found a good tool, GVM (the Groovy enVironment Manager), which is quite useful. the following is a brief introduction. GVM is a tool for

Today, in order to learn how to use groovy to write groovy's test code, we downloaded groovy 2.3.8 's source code package to Http://groovy.codehaus.org/Download.Groovy uses Gradle as the building tool.

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

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
