解决方法
FEST框架有一个工具来检测来自EDT的Swing使用情况.它基本上是一个RepaintManager安装.该框架面向测试,但RepaintManager可以在部署时使用.

或者,要检查所有方法,如getters和setter只能在EDT上访问,您可以使用AspectJ和加载时编织将SwingUtilities.isDisaptchThread()建议添加到您的swing组件(和JDK Swing组件)上的每个方法. )
@Aspect
public class EDTCheck {
@Pointcut("call (* javax.swing..*+.*(..)) || " +
"call (javax.swing..*+.new(..))")
public void swingMethods() {}
@Pointcut("call (* com.mystuff.swing..*+.*(..)) || " +
"call (com.mystuff.swing..*+.new(..))")
public void mySwingMethods() {}
@Pointcut("call (* javax.swing..*+.add*Listener(..)) || " +
"call (* javax.swing..*+.remove*Listener(..)) || " +
"call (void javax.swing.JComponent+.setText(java.lang.String))")
public void safeMethods() {}
@Before("(swingMethods() || mySwingMethods()) && !safeMethods()")
public void checkCallingThread(JoinPoint.StaticPart thisJoinPointStatic) {
if(!SwingUtilities.isDispatchThread()) {
System.out.println(
"Swing single thread rule violation: "
+ thisJoinPointStatic);
Thread.dumpStack();
// or you might throw an unchecked exception
}
}
}
(从文章稍微修改 – 添加mySwingMethods切入点,并使用SwingUtiliites.isDispatchThread()实际上与EventQueue.isDispatchThread()相同,但抽象更清洁.)
