但是，我收到了这个错误:
2012-02-25 15:39:48.329 WARN 16204—[nio-8080-exec-1] .w.s.m.s s。DefaultHandlerExceptionResolver: Resolved [org.springframework.http.converter.]HttpMessageNotReadableException: JSON解析错误:无法从START_ARRAY令牌中反序列化java.lang.String实例;嵌套异常是com.fasterxml. jacksondatabind.excs . mismatchedinputexception:无法反序列化START_ARRAY令牌之外的java.lang.String实例[来源:(PushbackInputStream);line: 1, column: 65973](通过参考链:br.com.ifenacon.idbs.orm.model.custom.NoticiaIdiomaDTO["noticiaDTOs"]- " java.util.ArrayList[1]- " br.com.ifenacon.idbs.orm.model.custom.noticito ["idiomaNoticia"]- " br.com.ifenacon.idbs.orm.model.IdiomaNoticia[" contudo"])]
问题是，在json中，您提供的上下文有两种类型(列表和字符串):
"conteudo": [],
和
"conteudo": "<p>uhuhuhuhuhu</p>",
这意味着它不能从List反序列化为String。反之亦然
这可能是一个糟糕的json文件。如果不是，你可以将它反序列化为Object然后在代码中使用toString()并确定它是否应该是一个列表并从那里手动反序列化它，或者直接使用它作为字符串
真正的错误是
不能反序列化java.lang.String的START_ARRAY实例[来源:[PushbackInputStream];行:1，列:65973](通过参考链:br.com.ifenacon.idbs.orm.model.custom.NoticiaIdiomaDTO(">noticiaDTOs")→java.util.ArrayList[1]→br.com.ifenacon.idbs.orm.model.custom.NoticiaDTO(">idiomaNoticia")→br.com.ifenacon.idbs.orm.model.IdiomaNoticia(">conteudo"]]>
p>如果你看一下JSON，这对应于"noticiaDTOs": [ { "idiomaNoticia": { "conteudo": "<p>uhuhuhuhuhu</p>", } } ]但是你也有一个
"noticiaDTOs": [ { "idiomaNoticia": { "conteudo": [], } } ]如果你需要一个String或Array，你需要检查你的数据模型。(给定的错误，我认为你定义它为字符串)你不能使用这两个相同的字段。这表明问题是你的JSON，那是不正确的。数组需要替换为字符串(或者您的数据模型需要更改为使用列表类型+必须在JSON中更改字符串项)
