With spring boot made two apis, between two APi call using the RestTemplate postForObject method, the return type is a custom ApiResponse,

Is called A API Controller

 
@ Controller 
Public class TestController {
@ RequestMapping (value="https://bbs.csdn.net/topics/invocationMethod", method=RequestMethod. POST) 
Public ApiResponse getContracts (@ PathVariable Integer id) {
ResultModel model=new ResultModel (); 
TestObject object=new TestObject (); 
Fild1 object. SetFild1 (" "); 
Fild2 object. SetFild2 (" "); 
Model. The setId (" 1 "); 
Model. The elegantly-named setName (" testName "); 
Model. SetObject (object); 
Return ApiResponse. Success (model); 
} 
} 

The return type ApiResponse

 
Public class ApiResponse {

//return code 200: OK 
Private Integer statusCode; 

//whole message 
private String message; 

//The component of data 
Private Object responseData; 



Private ApiResponse (ResultStatus status) {
Enclosing statusCode.=the status code (); 
This. Message=status. A tiny (); 
} 

Public static ApiResponse success (Object responseData) {
ApiResponse response=new ApiResponse (ResultStatus. SUCCESS); 
Return the response. SetResponseData (responseData); 
} 

} 

Returns the result ResultModel

 
Public class ResultModel {

private String id; 

Public String getId () {
return id; 
} 

Public void setId (String id) {
this.id=id; 
} 

Public String getName () {
return name; 
} 

Public void elegantly-named setName (String name) {
this.name=name; 
} 

Public TestObject getObject () {
The return object; 
} 

Public void setObject (TestObject object) {
Enclosing object=object; 
} 

private String name; 

Private TestObject object; 

} 

TestObject

 
Public class TestObject {

Private String fild1; 

Private String fild2; 

Public String getFild1 () {
Return fild1; 
} 

Public void setFild1 (String fild1) {
Enclosing fild1=fild1; 
} 

Public String getFild2 () {
Return fild2; 
} 

Public void setFild2 (String fild2) {
Enclosing fild2=fild2; 
} 

} 

B Api Model and Api Model are exactly the same,

B Api callback Api

 
Public class TestService {

The @autowired 
Private RestTemplate RestTemplate; 

Public ApiResponse callAapi () {

ApiResponse response=
RestTemplate. PostForObject (" http://localhost:9000/invocationMethod ", ", "
ApiResponse. Class); 
return response; 
} 
} 

When the ApiResponse ResponseData to ResultModel, wrong

 
Public ResultModel getResultModel (ApiResponse response) {
Return (ResultModel) response. GetResponseData (); 
} 

Fault is LinkedHashMap cannot convert ResultModel,

Want to ask about A Api response is actually A json string, through the entity class postForObject into the Bean, why can't the ResponseData in response to the Bean, but has been converted to linkedHashMap?
Investigation for a long time, didn't find the reason, hope to jar the great god, if you have see this post, assessment under the trouble, thank you!!!!!!!!!!

CodePudding user response:

This should go to the source code ~

CodePudding user response:

 ParameterizedTypeReference TypeRef=new ParameterizedTypeReference () {
}; 
ResponseEntity ResponseEntity=restTemplate. Exchange (url, HttpMethod. POST, new HttpEntity<> (MVM), typeRef); 
List MyModelClasses=responseEntity. GetBody (); 

add a ParameterizedTypeReference specified type
