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.

Oracle has supported groovy/grails as

Class is of course the groovy language inherits from the Java language, which means that the groovy language also inherits the reflection mechanism of the Java language. This means that we can write code like the following in the groovy language, as we would use reflection in the Java 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,
