如果代码里到处都是logger，明显不太好维护，而显得凌乱。
我们在throw时就把日志记录了，是最好的选择，代码如下：
package com.uet.common.exception;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
/**
* 数据获得：运行时RuntimeException
* <h3>使用场景</h3>
* <p>Action层使用</p>
* @author huangjs
* @version 2014-6-18 23:34:44
*/
public class ActionAccessException extends RuntimeException {
private static final long serialVersionUID = 1L;
public ActionAccessException() {
super();
getLogger().error("Exception", this);
}
public ActionAccessException(String message, Throwable cause) {
super(message, cause);
getLogger().error(message, cause);
}
public ActionAccessException(String message) {
super(message);
getLogger().error(message, this);
}
public ActionAccessException(Throwable cause) {
super(cause);
getLogger().error(cause.getMessage(), cause);
}
/**
* This method returns a logger which can be used by a subclass. The logger
* is specific for the instance of the Exception (the subclass).
*
* @return the class-specific Logger
*/
protected Logger getLogger() {
return LoggerFactory.getLogger(getClass());
}
}
