groovy.xml.MarkupBuilder禁用PrettyPrint

Question

我正在使用groovy.xml.MarkupBuilder来创建XML响应,但它创建了生成中不需要的漂亮打印结果.

        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)
            }
}

此代码生成:

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

但我不需要任何标识 - 我只想要一个简单的单行文本:)

IndentPrinter可以采用三个参数:a PrintWriter,缩进字符串和布尔值addNewLines.您可以通过addNewLines使用空缩进字符串设置为false 来获取所需的标记,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>
