由于网络问题经常会出现io异常,这时需要重复请求,并且设定一个异常重复请求次数n,当重复请求到第n次时再抛出io异常,这种问题不知道各位大侠是怎么处理的,有什么好办法?这是我的方法 for (int i=0;i<10;i++){//请求失败重复请求
try {
doc = Jsoup.parse(url, this.getTimeoutMills());
i=10;
} catch (IOException e) {
if(i==10-1){
throw e;
}
}
}
try {
doc = Jsoup.parse(url, this.getTimeoutMills());
i=10;
} catch (IOException e) {
if(i==10-1){
throw e;
}
}
}
public static void g(int n) throws IOException {
List<IOException> list = null;
while (n > 0) {
try {
doc = Jsoup.parse(url, this.getTimeoutMills());
return;
} catch (IOException io) {
if (list == null) {
list = new ArrayList<IOException>(n);
}
list.add(io);
n--;
}
}
ManyIOException ex = new ManyIOException();
ex.setList(list);
throw ex;
} public static class ManyIOException extends IOException { public ManyIOException(String message) {
} public ManyIOException() {
}
private List<IOException> list; public List<IOException> getList() {
return list;
} public void setList(List<IOException> list) {
this.list = list;
}
}
if(i!=10){ continue;}
else{throw e}
