我有一个需要返回大型ArrayList的函数：
LogData response = (LogData) target.path("logs")
.queryParam("searchStr", "Some string")
.request().get(LogData.class);
使用：
@XmlRootElement
public class LogData
{
private ArrayList<String> listStr;
private String logStr;
public ArrayList<String> getLogList()
{
return this.listStr;
}
public void setLogList(ArrayList<String> listStr)
{
this.listStr = listStr;
}
public String getLogStr()
{
return this.logStr;
}
public void setLogStr(String logStr)
{
this.logStr = logStr;
}
}
和
@GET
@Path("/logs")
@Produces({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
public LogData getAllMatchedStrInLogFile(@QueryParam("searchStr") String searchStr) {
logger.debug("Check if string \"{}\" is in file {}", searchStr, fileName);
LogData logsParsed = new LogData();
ArrayList<String> parsedList = getParsedListStr("myFile.txt", searchStr);
logsParsed.setLogList(parsedList);
return logsParsed;
}
但我得到了这个例外：

如果返回的arraylist大小是＆lt; 150，它不会返回此异常，但如果它的＆gt; 150，它会。因此，我不确定如何延长超时或如何扩大标头以适应我的大响应。
任何帮助将不胜感激。谢谢！
