抽象类 继承于 Exception
public abstract class AbstractException extends Exception{
private ErrorInfo info.
public AbstractException(ErrorInfo message) {
super(message.getErrorCode() message.getErrorName() message.getErrorInfo()).
info = message.
}
public String getCode()
{
return info.getErrorCode().
}
}
错误实体
public class ErrorInfo {
private String ErrorCode.
private String ErrorName.
private String ErrorInfo.
public ErrorInfo(String temp1,String temp2,String temp3) {
this.ErrorCode = temp1.
this.ErrorName = temp2.
this.ErrorInfo = temp3.
}
public String getErrorCode()
{
return this.ErrorCode.
}
public String getErrorName()
{
return this.ErrorName.
}
public String getErrorInfo()
{
return this.ErrorInfo.
}
}
错误集合
public class ErrorPool {
private java.util.HashMap errorMap = new java.util.HashMap().
public ErrorPool() {
errorMap.put("Center1001",new ErrorInfo("Center1001","严重错误，适配器无效","因为适配器所在前置机网络异常，造成适配器无效")).
}
public ErrorInfo getErrorInfo(Object errorCode)
{
return (ErrorInfo)errorMap.get(errorCode).
}
}
异常实现
public class TestException extends AbstractException {
private ErrorInfo info.
public TestException(ErrorInfo message)
{
super(message).
info = message.
}.
public String getCode()
{
return super.getCode().
}
public void LogDebug()
{
System.out.println("debug info.....").
}
}
具体使用代码
public class Test {
public Test() {
}
public void kk(String usename) throws TestException
{
if (usename.equals("fuck"))
{
}
else
{
throw(new TestException((new ErrorPool()).getErrorInfo("Center1001"))).
}
}
public static void main(String[] agrgs)
{
try
{
Test tt = new Test().
tt.kk("xxx").
}
catch(TestException e)
{
System.out.println(e.getCode()).
e.printStackTrace().
e.LogDebug().
}
}
}
