春天休息不返回JSON对象 - 越来越404

Question

我已经找了几天，没有运气..我得到一个HTTP 404，并找不到我失踪，为什么它不接我的映射。我做错了吗？

我正在使用Spring Rest并试图使用@ResponseBody注释返回一个json对象。请帮忙！我使用的是jackson-core-2.2.3.jar，jackson-databind-2.2.3.jar和jackson-annotations-2.2.3.jar。这是我的代码，我的服务器日志如下。感谢帮助！

Answer 1

也许你应该定义方法应该生产什么。 你可以通过设置RequestMapping注释的produce属性来实现。

实施例： @RequestMapping（值= “地址/ {街道}/{拉链}”，方法= RequestMethod.GET，产生= {MediaType.APPLICATION_JSON_VALUE}）

Answer 2

试着改变你的标题属性的值，以

"Accept=application/json"
