一个通用的类的toString()方法

public String toString() {

try {

Map map = BeanUtils.describe(this);

Iterator keyIt = map.keySet().iterator();

StringBuffer aBuffer = new StringBuffer();

while (keyIt.hasNext()) {

String key = (String) keyIt.next();

if ("class".equals(key)) {

continue;

}

String value = (String) map.get(key);

if (aBuffer.length() > 0) {

aBuffer.append(", ");

}

aBuffer.append(key + " = [" + value + "]");

}

return aBuffer.toString();

} catch (Exception e) {

return super.toString();

}

}
