我使用Spring Security ACL plugin并且之前没有设置ACL。我想访问以下服务方法：
@PostFilter("hasPermission(filterObject, read) or hasPermission(filterObject, admin)")
List<Company> list(Map params = [:]) {
return Company.list(params)
}
我允许公司的管理员用户。当我访问上述方法时，一切正常。当我停止服务器并执行grails clean时，会出现问题。当我重新启动并访问上述方法时，我收到以下错误。这很奇怪，因为它在grails清理之前第一次没有错误。

我在这里创建了一个演示项目：https://github.com/confile/Spring-Security-ACL-Bug
重现它：
编辑：我发现当我关闭我的mysql服务器并重新启动它时，错误就消失了。它可能属于一些缓存问题。
有没有办法捕获此错误，例如，如果之前未设置过ACL？
注意：此问题仍无法解答。
答案 0 :(得分：1)
这个问题似乎与AclSid覆盖插件中的问题的方式有关。
当插件类以某种方式获胜时，您将看到grails package问题。
有一个简单的解决方法一般情况下你应该在执行grails clean之后运行package，还需要确保在你的ci服务器上运行import java.io.FileNotFoundException;
import java.io.FileWriter;
import java.io.IOException;
import java.io.PrintWriter;
import java.io.FileReader;
import java.io.BufferedReader;
public class Search {
public static void main(String[] args) throws IOException { //main method
boolean match = false;
String creditNumber = null;
BufferedReader reader1 = new BufferedReader(new FileReader("creditCards1.txt"));
creditNumber = reader1.readLine();
while(match = false & creditNumber != null){
System.out.println(creditNumber);
boolean confirm = false;
confirm = searchTwo(creditNumber);
if(confirm == true){
confirm = searchTwo(creditNumber);
System.out.println(confirm);
break;
}
reader1.close();
}
}
public static boolean searchTwo(String creditNumber) throws IOException { //method for searching the 2nd text file
boolean match = false;
String creditNumber2 = null;
BufferedReader reader2 = new BufferedReader(new FileReader("creditCards2.txt"));
creditNumber2 = reader2.readLine();
while(match = false & creditNumber != null){
boolean confirm = false;
confirm = searchThree(creditNumber2);
if(confirm == true & creditNumber2.equals(creditNumber)){
match = true;
System.out.println(creditNumber2);
}
creditNumber2 = reader2.readLine();
}
reader2.close();
if(match = true || creditNumber2 == null){
return match;
}
return match;
}
public static boolean searchThree(String creditNumber) throws IOException { //method for searching the 3rd text file
boolean match = false;
String creditNumber3 = null;
BufferedReader reader3 = new BufferedReader(new FileReader("creditCards3.txt"));
creditNumber3 = reader3.readLine();
while(match = false & creditNumber != null){
if(creditNumber3.equals(creditNumber)){
match = true;
break;
}
creditNumber3 = reader3.readLine();
}
reader3.close();
if(match = true || creditNumber3 == null){
return match;
}
return match;
}
}
步骤之前建立你的战争。
我已经看到了同样的问题，因为我们使用UUID并且必须使AclSid类也有sid的字符串。一旦我们开始正确运行包装步骤，我就没有生产或本地问题。
