Grails无法将会话作用域服务注入到控制器 [英] Grails unable to inject session scoped service to controller
问题描述
我正在尝试向控制器注入会话范围的服务。这里是我的控制器类ActionController.groovy:
包rafonline
导入grails.converters.JSON
import grails.plugin.springsecurity.annotation.Secured
@Secured(ROLE_ADMIN)
class ActionController {
def tweetingService
def index(){
$ b def retweetUsers(){
String message =done
boolean success = true
try {
最后def句柄= String.valueOf(params.handles).trim()。split(\\\
)
最终def口令= String.valueOf(params.passwords).trim()。split(\\ \\ n)
final def numRTs = String.valueOf(params.numRTs).trim()。split(\\\
)
final def statusIdsString = String.valueOf(params.tweetURLs)。 trim()。split(\\\
)
if(!tweetingService.isRunning){
new Thread(new Runnable(){
@Override
void r un(){
tweetingService.retweetUsers(statusIdsString,句柄,密码,numRTs);
}
})。start();
}
} catch(Exception e){
message = e.getMessage()
success = false
}
render contentType:'text / json ',text:[success:success,message:$ {message}] as JSON
}
def getUpdateProgress(){
render contentType:'text / json',text:[运行:tweetingService.isRunning,message:tweetingService.messsage] as JSON
}
}
以下是我的会话scoped service TweetingService.groovy:
包rafonline
导入grails。 transaction.Transactional
import org.jsoup.Connection
import org.jsoup.Jsoup
import org.jsoup.nodes.Document
import org.jsoup.nodes.Element
import org.jsoup.select.Elements
@Transactional $ b $ class TweetingService {
private final String PARAM1 =some1;
private final String PARAM2 =some2;
private final String PARAM3 =some3;
private final String USER_AGENT =some4;
private final Long TIMEOUT = 60000
static scope =session
def messsage =Waiting
def isRunning = false
def stopit = false
def retweetUsers(String [] statusIds,String [] username,String [] password,String [] numRTs){
if(isRunning){
return
} else {
try {
int count = 1;
isRunning = true
statusIds = convertStatusURLArrayToStatusIDArray(statusIds)
def totalLength = statusIds.length
for(int i = 0; i< statusIds.length; i ++ ){
def statusId = statusIds [i]
def numRT = username.length
try {
numRT = Integer.parseInt(numRTs [i])
} catch (例外e){
numRT =用户名。长度
}
shuffleArray(用户名,密码)
messsage =处理$ {totalLength}的$ {i + 1}
for(int j = 0; j if(stop){
stop = false
break;
try {
//做某事
} catch(Exception e){
e.printStackTrace();
}
messsage =已处理总额:$ {totalLength}失败:$ {totalLength - count}成功:$ {count}
}
}
} catch (例外e){
}最后{
isRunning = false
}
}
}
def Map< String ,String> getFormParams(String html,String username,String password)

那么我不允许简单地将一个会话作用域服务注入到控制器中?或者我做错了什么?
编辑:
我已经看过这个链接并尝试设置static proxy = true。然而,它不起作用,同样的错误。试图改变Config.groovy控制器的默认范围
//控制器的默认范围。可能是原型,会话或单身。
//如果未指定,控制器是原型范围。

So am I not allowed simply inject a session scoped service to a controller? Or what am I doing wrong?
EDIT:
I have already seen this link and tried setting static proxy=true. Yet it does not work and same error.
Try to change the default scope for controllers in Config.groovy
// The default scope for controllers. May be prototype, session or singleton.
// If unspecified, controllers are prototype scoped.
grails.controllers.defaultScope = 'session'
