Question

版本3.5.1的编译失败在生成的服务代理上，错误 - 未报告的异常java.io.UnsupportedEncodingException;必须被抓住或宣布被抛出

生成“throw t”错误的代理代码 -

public void handle(Message msg) {
try {
...
}
catch (Throwable t) {
msg.reply(new ServiceException(500, t.getMessage()));
throw t;
}
}

Stacktrace -

UserAsyncServiceVertxProxyHandler.java:[339,7] unreported exception java.io.UnsupportedEncodingException; must be caught or declared to be thrown

界面中的一个方法是抛出UnsupportedEncodingException。所以代码生成失败了。确保接口不会抛出任何已检查的异常，否则代码生成将失败。

这是界面中的方法。

void generateQRUrl（User user，Handler＆gt; resultHandler）抛出UnsupportedEncodingException;

Vertx服务代理代码生成编译错误
