我正在尝试从 Linux 盒子获取命令输出
例如:tnsping
我想保留它的换行符。
下面是我添加命令并将frows其传递给函数执行的代码
def oracleCommand(csm,pluginOutputs)
{
HashMap<String,String> params = IntermediateResults.get("userparams")
Map env=AppContext.get(AppCtxProperties.environmentVariables)
def fClass = new GroovyClassLoader().parseClass( new File( 'plugins/infa9/Infa9CommandExecUtil.groovy' ) )
List<String> frows
frows=["tnsping $params.tns"] //for the time being only one command is here
List<String> resultRows = fClass.newInstance().fetchCommandOutput( params, env, frows )
csm.oracleCommand(){
oracle_input(frows[0]){}
oracle_output(resultRows[0]){}
}
}

在下面的代码中,我正在读取结果,根据换行符分割结果,这样我的所有换行符都消失了
public List<String> fetchCommandOutput( Map<String,String> params, Map env, List<String> rows )
{
List<String> outputRows = new ArrayList<String>()
try
{
for(item in rows)
{
String temp=item.toString()
Process proc = Runtime.getRuntime().exec(temp);
InputStream stdin = proc.getInputStream();
InputStreamReader isr = new InputStreamReader(stdin);
BufferedReader br = new BufferedReader(isr);
String line = null;
result = new StringBuffer()
line=null
while ((line = br.readLine()) != null)
{
result.append(line+" #10#13 ") //Here i am trying to add the newline again, but it does not reflect in the generated xml. it just come as plain text
}
String tRes=result
tRes=tRes.trim()
outputRows.add(tRes)
int exitVal = proc.waitFor();
}
}
catch (IOException io)
{
io.printStackTrace();
}
catch (InterruptedException ie)
{
ie.printStackTrace();
}
return outputRows
}

我如何保留换行符或回车符,以便当使用 xsl 打开 xml 时以及遇到<pre></pre>它时应该保留其格式?
如果我猜对了,你应该使用\rand \n:
result.append(line+"\r\n");

或者,您可以从系统获取行分隔符:
result.append(line+System.getProperty("line.separator"));
