Chinese garbled code caused by Grails

In a Grails Inside the project , I want to write a filter for bad information Service, And put the filtering rules in xml In the document .

following xml File placement bad information , Contains words 、 Phrases and syntax , regular expression ：

<filter>
    <words>
        <word>fuck</word>
        <word>kill</word>
    </words>
    <phrases>
        <phrase>asshole</phrase>
    </phrases>
    <grammars>
        <grammar>kick.*ass</grammar>
        <grammar>impud.nce</grammar>
    </grammars>
</filter>

Then there is a filter Service：

classFilterService{
    def private static node=newXmlParser().parse(newFile('./config/filter.xml'))
    static Stringfilter(Stringsource){
        def substitution=node.substitution.text()
        def sensitive=[node.words.word*.text().join('|'),
        node.phrases.phrase*.text().join('|'),
        node.grammars.grammar*.text().join('|')].join('|')

        if(!source||!sensitive)returnsource
            returnsource.replaceAll(sensitive,substitution)
    }
}

That's the code , It turns out that Grails There is a Chinese problem while running , And not just pages , stay filter Chinese cannot be displayed correctly in the method , and Service The same code in common Groovy There is no Chinese problem in the application .

As before J2EE Development experience , Try the following method ：

String result=new String(testString.getBytes("iso-8859-1"),"UTF-8")

Still garbled ……

Try it again ： Add defined operating parameters -Dfile.encoding=UTF-8 Invalid ……

xml Add... To the document

<?xmlversion="1.0"encoding="UTF-8"?>

It still doesn't work ……

I've been thinking about it for a long time , Come up with a solution ：

For example, we plan to unify the coding of the whole project into UTF-8 Format , I use Eclipse Development , my Eclipse The default code is GBK Of , Then this can remain unchanged , Right click on the project , choice Properties Medium Resource, take Text file encoding Set to UTF-8.

Be careful ： The consequence is the project groovy And other documents originally used GBK Chinese will become garbled ！ So please choose the appropriate code .

Then delete the operating parameters -Dfile.encoding=UTF-8.

Make another change ：

// The original 
def node=newXmlParser().parse(newFile('./config/filter.xml'))
// Change it to 
def node=newXmlParser().parseText(newFile('./config/filter.xml').getText())

Last , The old rule on the page , add ：

<meta http-equiv="Content-Type" content="text/html; charset=GBK" />

That's all right. .

If your code is GBK Of , Handle it the same way .
