本文介绍了当服务器数据类型与客户端不一致时出现的org.springframework.http.converter.HttpMessageNotReadableException异常，具体表现为无法将JSON中的对象转换为字符串类型。文章详细解释了错误原因并提供了相应的解决方案。

org.springframework.http.converter.HttpMessageNotReadableException: Could not read JSON: Can not deserialize instance of java.lang.String out of START_OBJECT token
 at [Source: org.apache.http.conn.EofSensorInputStream@42b0f150; line: 1, column: 112] (through reference chain: com.webservice.net.model.GetAffairNewsListResponse["list"]->com.webservice.net.model.AffairNewsList["publishTime"]); 

nested exception is org.codehaus.jackson.map.JsonMappingException: Can not deserialize instance of java.lang.String out of START_OBJECT token

 at [Source: org.apache.http.conn.EofSensorInputStream@42b0f150; line: 1, column: 112] (through reference chain: com.webservice.net.model.GetAffairNewsListResponse["list"]->com.webservice.net.model.AffairNewsList["publishTime"])

遇到这样的错误，主要是服务器数据和客户端数据类型不一致，这里遇到的publishTime数据类型，服务器是datetime型，而我客户端数据是String型，就会导致这样的错误，调成一致即可。
