JsonParseException：意外字符（'<'（代码 60））：需要一个有效值（数字、字符串、数组、对象、'true'、'false' 或 'null'）
JsonParseException: Unexpected character ('<' (code 60)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')
我有一个程序可以将新患者插入服务器内 docker 容器中的 HBase。一切正常，直到我尝试将连接 IP 更改为 phoenix 查询服务器以进行 运行 JUnit 测试。我在这样的属性文件中设置 URL：
java.lang.RuntimeException: com.fasterxml.jackson.core.JsonParseException: Unexpected character ('<' (code 60)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')
at [Source: java.io.StringReader@1105b1f; line: 1, column: 2]

我不确定为什么会收到 json 解析异常。由于外部 api，调试没有帮助。我什至不知道异常是否与我的属性文件中 URL 的格式有关，是否与患者（以 xml 格式出现）有关，甚至可能与 phoenix 客户端有关。
我已经启动了 phoenix 查询服务器，看起来它可以连接到它，因为它之前抛出一个 "connection refused" 异常，现在却没有。
我在 pom.xml 中添加了 phoenix，如下所示：
<dependency>
<groupId>org.apache.phoenix</groupId>
<artifactId>phoenix-server</artifactId>
<version>4.7.0-HBase-1.1</version>
</dependency>
但我不知道是否需要为 phoenix-thin-client 添加其他内容。如果必须的话，我找不到该依赖项，所以我假设它已包含在内。
感谢任何帮助！

你的Phoenix服务器升级了吗？看起来它试图同时使用 JSON 和 Protocol Buffer 协议进行连接。它应该是一个或另一个。
检查您是否正确提供授权、headers和其他参数。
我通过检查这些步骤解决了。
