drools规则引擎之注释

像Java开发语言一样，Drools文件中也可以添加注释。注释部分Drools引擎是会将其忽略调的。单行注释使用“//”，示例如下：

rule "Testing Comments"
when
    // this is a single line comment
    eval( true ) // this is a comment in the same line of a pattern
then
    // this is a comment inside a semantic code block
end

注意，使用“#”进行注释已经被移除。多行注释与Java相同，采用“/*注释内容*/”，来进行注释，示例如下：

rule "Test Multi-line Comments"
when
    /* this is a multi-line comment
       in the left hand side of a rule */
    eval( true )
then
    /* and this is a multi-line comment
       in the right hand side of a rule */
end
