我有一个网络服务，它在 modeshape 内容存储库中搜索文本。界面看起来像这样：
@POST
@Path("globalSearch")
@Consumes(MediaType.TEXT_PLAIN)
@Produces(MediaType.TEXT_XML)
public String globalSearch(String search) {
XMLConverterService xmlOb = new XMLConverterService();
Map<String,String> param = xmlOb.fetchMapFromXml(search);
StringBuffer xmlString = new StringBuffer();
xmlString.append("<xml>");
int count = 0;
List<Map<String, String>> result = (new DataInterfaceService())
.fetchGlobalSearch(param);
if(result!=null){
for (Map<String, String> map : result) {
count++;
xmlString.append("<result" + count + ">")
.append(xmlOb.fetchXmlFromMap(map))
.append("</result" + count + ">");
}
xmlString.append("</xml>");
return xmlString.toString();
}
return null;
}
fetchGlobalSearch() 函数看起来像这样：
public List<Map<String, String>> fetchGlobalSearch(Map<String, String> param) {
logger.log(Level.INFO, "entering fetchGlobalSearch");
String keyWord = param.get("keyword");
String type = param.get("type");
List<Map<String, String>> listOfMaps = null;
Map<String, String> retValue = null;
String qry = "";
if (type.equalsIgnoreCase("GRA")) {
qry = "SELECT [med:UNIQUE_ID],[med:GRPNAME],[med:CSR],[med:UW],[med:GROUP_STATE],[med:STR_DATE] "
+ "FROM [med:notes] where contains([med:XML_STORE], $uuid)";
} else {
qry = "SELECT [fur:UNIQUE_ID],[fur:MM],[fur:FROMUW],[fur:INSURED],[fur:POLICY_NUM],[fur:UWCSRDATE],[fur:FURCOMPDATE],[fur:FUR_DATE],[fur:CSRCOMPDATE] "
+ "FROM [fur:notesfur] where contains([fur:XML_STORE], $uuid)";
}
try {
Query qr = qrym.createQuery(qry, Query.JCR_SQL2);
Value uid = session.getValueFactory().createValue(keyWord);
qr.bindValue("uuid", uid);
QueryResult resultSet = qr.execute();
String[] columns = resultSet.getColumnNames();
RowIterator rowiter = resultSet.getRows();
while (rowiter.hasNext()) {
if (listOfMaps == null)
listOfMaps = new ArrayList<Map<String, String>>();
retValue = new HashMap<String, String>();
Row row = rowiter.nextRow();
for (String column : columns) {
if (row.getValue(column) != null) {
retValue.put(column, row.getValue(column).toString());
}
}
listOfMaps.add(retValue);
}
} catch (RepositoryException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
logger.log(Level.INFO, "exiting fetchGlobalSearch");
return listOfMaps;
}
我通过以下代码访问网络服务：
private static void callGlobalSearch(){
try {
String param = "";
param = fetchGlobalParams();
System.out.println("param : " + param);
// Create a socket connection to the host
URL url = new URL(
"http://localhost:8080/xxttrr/rest/globalSearch");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
// make url connection
conn.setDoOutput(true);
conn.setDoInput(true);
conn.setUseCaches(false);
conn.setAllowUserInteraction(true);
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type",
"text/plain; charset=utf-8");
conn.setRequestProperty("Content-Length", Integer.toString(param.getBytes().length));
DataOutputStream printout = new DataOutputStream (conn.getOutputStream());
printout.writeBytes(param);
printout.flush();
printout.close();
BufferedReader in = new BufferedReader(new java.io.InputStreamReader(conn.getInputStream()));
String line;
while ((line = in.readLine()) != null) {
System.out.println(line);
}
in.close();
conn.disconnect();
} catch (Exception e) {
System.out.println("Error: " + e);
}
}
问题是当我对本地 modeshape 存储库进行 Web 服务调用时，结果按预期返回。但是当我在我的 DEV 服务器中部署代码时，它会形成以下日志：

并终止。
它与模式形状配置或网络服务有关吗？只是让您知道，在某一时刻，modeshape 中可能有一百万条记录。导致问题的超时也是如此。如果是这样，那么我该如何配置我的网络服务，使其可以存活 5 分钟？
任何帮助，将不胜感激。相同代码在不同服务器中的行为方式不同，这确实令人困惑。
