当想要返回的是json数据,produces写的"text/plain",会报错
@RequestMapping(value = "/getDynamicByDynamicId1",produces = "text/plain")
@ResponseBody
public Dynamic getDynamicByDynamicId1(){
System.out.println();
return dynamicMapper.getDynamicByAnnotationFromDynamicId(1l);
}
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Acceptable, status=406).
Could not find acceptable representation
org.springframework.web.HttpMediaTypeNotAcceptableException: Could not find acceptable representation
改为
@RequestMapping(value = "/getDynamicByDynamicId1",produces = "application/json")
@ResponseBody
public Dynamic getDynamicByDynamicId1(){
System.out.println();
return dynamicMapper.getDynamicByAnnotationFromDynamicId(1l);
}
