我有一个Spring Boot app暴露了v1/data/groceries端点：
interface GroceryItemPersistor extends CrudRepository<GroceryItem, Long> {
@Query('FROM grocery_items WHERE grocery_item_name = :name')
GroceryItem findByName(@Param('name') String name)
@Query('FROM grocery_items')
List<GroceryItem> getAllGroceries()
}
@RestController
@RequestMapping('v1/data/groceries')
class GroceryItemResource {
@Autowired
GroceryItemPersistor groceryItemPersistor
@GetMapping
List<GroceryItem> getAllGroceries() {
groceryItemPersistor.getAllGroceries()
}
...
}
但是当我运行应用程序时（请参阅链接的自述文件）并发出以下curl语句：
curl -k -H "Content-Type: application/json" -X GET http://localhost:9200/v1/data/groceries
我认为这是卷曲的输出：
<html>
<head>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8"/>
<title>Error 404 Not Found</title>
</head>
<body><h2>HTTP ERROR 404</h2>
<p>Problem accessing /error. Reason:
<pre> Not Found</pre></p>
</body>
</html>
然后，回到服务运行的终端，我看到以下控制台输出响应curl命令：
08:57:39.246 [qtp1939022383-16] WARN o.s.web.servlet.PageNotFound - No mapping found for HTTP request with URI [/error] in DispatcherServlet with name 'dispatcherServlet'
08:57:39.247 [qtp1939022383-16] WARN o.e.j.server.handler.ErrorHandler - Error page loop /error
两个问题：
试试这个：
@RequestMapping注释;@GetMapping注释替换为放入下一个注释的getAllGroceries()方法：
@GetMapping(value = "/v1/data/groceries", produces = "application/json;UTF-8")<br>
@ResponseBody
