【问题描述】：
晚上好，
我有这个 Spring Boot 应用程序，我想返回一个 HashMap。但是，当我调用我的端点方法时，我得到了这个异常：

我调用的方法是：
@RequestMapping(value = "/checkProcess", method = RequestMethod.GET)
public ResponseEntity<Map<Long, Integer>> checkProjectInDeliveryProcess() {
Map<Long, Integer> map = new HashMap<Long, Integer>();
map.put(10L, 38);
return ResponseEntity.ok(map);
}
我做了一些研究没有成功，下面有更多信息： 该应用程序部署在 Weblogic 12c 上； 使用 Springboot 1.4.3 版本；
我试过这个Stackoverflow procedure，但没有运气。 当我尝试返回一个列表时，也会出现同样的问题。
有人已经经历过这样的事情吗？
提前谢谢大家

查看 jackson jar 以获取它说它不可用的方法。您是否尝试过使用不同版本的 Jack jar ？ java.lang.NoSuchMethodError: com.fasterxml.jackson.databind.ObjectWriter.forType(Lcom/fasterxml/jackson/databind/JavaType;)Lcom/fasterxml/jackson/databind/ObjectWriter;
-
我有两个建议：将生产参数添加到 @RequestMapping(value = "/checkProcess", method = RequestMethod.GET,produces = MediaType.APPLICATION_JSON_UTF8) 或作为之前建议的人。通常当你得到 NoSuchMethod 异常时，它与 jackson 的版本太旧有关。

我会检查jar，实际上应用程序有点旧，关于添加生产参数，我试过了，把这个问题留在这里，还是谢谢你。
