xml - groovy.xml.MarkupBuilder 禁用 PrettyPrint

Question

我正在使用 groovy.xml.MarkupBuilder 创建 XML 响应，但它创建了生产中不需要的 pretty-print 结果。

        def writer = new StringWriter()
        def xml = new MarkupBuilder(writer)
        def cities = cityApiService.list(params)

        xml.methodResponse() {
            resultStatus() {
                result(cities.result)
                resultCode(cities.resultCode)
                errorString(cities.errorString)
                errorStringLoc(cities.errorStringLoc)
            }
}

此代码产生:

<methodResponse> 
  <resultStatus> 
    <result>ok</result> 
    <resultCode>0</resultCode> 
    <errorString></errorString> 
    <errorStringLoc></errorStringLoc> 
  </resultStatus> 
</methodResponse> 

但我不需要任何标识 - 我只需要一个普通的单行文本 :)

IndentPrinter可以采用三个参数:PrintWriter、缩进字符串和 bool 值 addNewLines。您可以通过使用空缩进字符串将 addNewLines 设置为 false 来获得所需的标记，如下所示:

import groovy.xml.MarkupBuilder

def writer = new StringWriter()
def xml = new MarkupBuilder(new IndentPrinter(new PrintWriter(writer), "", false))

xml.methodResponse() {
    resultStatus() {
        result("result")
        resultCode("resultCode")
        errorString("errorString")
        errorStringLoc("errorStringLoc")
    }
}

println writer.toString()

结果:

<methodResponse><resultStatus><result>result</result><resultCode>resultCode</resultCode><errorString>errorString</errorString><errorStringLoc>errorStringLoc</errorStringLoc></resultStatus></methodResponse>
