我有一个从java执行的bat文件，并将输出结果保存在java变量中。脚本从cmd运行时运行良好，也从java执行，我在java中得到了exit值，但无法得到返回值。下面是我正在使用的java代码和bat脚本。
java代码

String filePath = "1234";
StringBuilder scriptOutputResult = new StringBuilder();
Process process = Runtime.getRuntime().exec(new String[]{"cmd.exe", "/c", "start C:\\Thread\\Value\\xyz.bat", filePath});
exitCode = process.waitFor();
log.info("Command returned exit code = {}", exitCode);
try (BufferedReader stdInput = new BufferedReader(new InputStreamReader(process.getInputStream()))) {
    log.info("Reading the output of shell script");
    String line = null;
    while ((line = stdInput.readLine()) != null) {
        scriptOutputResult.append(line).append("\n");
         }
     log.info("Output from the script executed is :{}", scriptOutputResult.toString());
}

输出.log

Command returned exit code = 0
Output from the script executed is :

xyz.bat公司

@ECHO OFF
SET filePath=%1
ECHO %filePath%

IF "%filePath%" == "" (
    ECHO Missing File Path
    EXIT /B 1
    GOTO :eof
    ) ELSE (
    ECHO %filePath%
    EXIT /B 0
    GOTO :eof
)

请让我知道，如果我在批处理文件或任何其他方式，以获得文件的输出在java中以其他方式丢失的东西。
