java - Spring PUT 请求 : Unsupported Media Type (Code: 415)

Question

我有一个相当晦涩的问题，经过几天的调试后我无法弄清楚。问题是我们的 PUT REST API 之一开始在生产中抛出 Unsupported Media type。下面是方法的定义:

@RequestMapping(value = "/v1/put/user/profile", method = RequestMethod.PUT)
    public String updateProfile(@RequestBody UserAndroid user, ModelMap model,
            HttpServletRequest request, HttpServletResponse response) {

    }

在 PUT 请求中，我们只是传递手机号码，如下所示:

{ "mobile": "9999559848"}

这是 UserAndroid 实体:

https://gist.github.com/madhur/eb0d9d006f4e4da706d7

现在，最令人惊讶的部分。在跟踪 github 提交后，我们将错误追溯到 User 中新引入的字段(不是 UserAndroid。它们不同但相关)实体 ( https://gist.github.com/madhur/06bbcfe11c0e751ab4df ) :

@OneToOne(mappedBy="user", fetch=FetchType.LAZY)
private FullContactDetails fullContactDetails;

如果我们删除这个字段，API 就会开始正常工作。谁能告诉我为什么会这样？

更新:这是执行请求时的 Spring MVC 日志:

使用 Spring 3.2.2。是的，我们在类路径中同时拥有 gson-2.2.4.jar 和 jackson。

Answer 1

请检查您在其中定义了内容协商 View 解析器的 XML 配置，您应该在那里定义了 json 类型媒体类型的映射。更新这些更改后查看它是否有效

这并没有直接解决问题，但在内部很少有依赖项解决了 json 的内容类型映射，如果它有效，请尝试
