Jackson报错Illegal unquoted character ((CTRL-CHAR, code 11)): has to be escaped using backslash to be included in string value

当你在使用 Jackson 库的时候，可能会遇到类似于 "Illegal unquoted character ((CTRL-CHAR, code 11))" 的报错信息。这个错误通常是由于字符串中包含了未转义的控制字符所引起的。

(1).原始代码

Java

代码语言：javascript复制

// 转换为实体
ObjectMapper objectMapper = new ObjectMapper();
CorpChatMessage corpChatMessage = objectMapper.readValue(corpChatMessageJson, CorpChatMessage.class)

原始Json如下：

JSON

代码语言：javascript复制

{"msgid":"11929905846625519600_11703315634393","action":"send","from":"ghldf","tolist":["wang1wf1"],"roomid":"","msgtime":1703315630081,"msgtype":"text","text":{"content":"直营亮点n 首月突破1080万"}}

很明显Json字符串包含了未转义的换行符

(2).解决代码

Java

代码语言：javascript复制

objectMapper.configure(JsonReadFeature.ALLOW_UNESCAPED_CONTROL_CHARS.mappedFeature(),true)

其中，JsonReadFeature.ALLOW_UNESCAPED_CONTROL_CHARS 表示允许未转义的控制字符，在调用 configure() 方法时将其设置为启用即可。
