kafka发送的字符串长度问题

我在客户端模拟发送一个特别长的字符串，客户端会漏掉一部分。请问这种情况怎么解决，谢谢。

发送的消息如下

{"header":{"msgId":10,"lineId":6},"msgBody":{"a":2,"b":[{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6},{"c":6,"d":6,"e":6,"f":6,"g":"a","h":"a","i":"a","j":6,"k":"a","l":"a","m":6,"n":6,"o":6}]}}
