本文介绍了使用SpringMVC框架中如何通过GET和POST请求进行API调用，包括设置Authorization头、参数传递以及错误处理。示例涉及`/searchEntryRecordPageList`、`/searchCheckResultByEntryRecordId`和`/batchAddCart`这三个接口。

1、get请求

@GetMapping("/searchEntryRecordPageList")
public JSONObject searchEntryRecordPageList(@RequestParam Map<String,Object> params){
    HttpHeaders requestHeaders = new HttpHeaders();
    requestHeaders.add("Authorization","Bearer "
    + String.valueOf(params.get("access_token")));
    MultiValueMap<String, Object> entryRecordParam = 
    new LinkedMultiValueMap<String, Object>();
    entryRecordParam.add("offset",params.get("offset"));
    entryRecordParam.add("limit",params.get("limit"));
    entryRecordParam.add("yzOpenId",params.get("yzOpenId"));
    HttpEntity<MultiValueMap<String, Object>> requestEntity = 
    new HttpEntity<MultiValueMap<String, Object>>(entryRecordParam, requestHeaders);
    ResponseEntity<Map> response = null;
    try {
        response =         restTemplate.exchange(yzymUrl+"/app/entryRecord/searchEntryRecordPageList",         HttpMethod.POST, requestEntity, Map.class);
    }catch (Exception e){
        return exceptionObj(e.getMessage());
    }
    logger.info(JSONObject.toJSONString(response.getBody()));
    return (JSONObject) JSONObject.toJSON(response.getBody());
}

@GetMapping("/searchCheckResultByEntryRecordId")
public JSONObject searchCheckResultByEntryRecordId(@RequestParam 
Map<String,Object> params){
    HttpHeaders requestHeaders = new HttpHeaders();
    requestHeaders.add("Authorization","Bearer "
    + String.valueOf(params.get("access_token")));
    MultiValueMap<String, Object> entryRecordParam = 
    new LinkedMultiValueMap<String, Object>();
    HttpEntity<MultiValueMap<String, Object>> requestEntity = 
    new HttpEntity<MultiValueMap<String, Object>>(entryRecordParam, requestHeaders);
    ResponseEntity<Map> response = null;
    try {
        response =     restTemplate.exchange(yzymUrl+"/app/entryRecord/searchCheckResultByEntryRecordId?entryRecordId="+params.get("entryRecordId"), 
HttpMethod.GET, requestEntity, Map.class);
    }catch (Exception e){
        return exceptionObj(e.getMessage());
    }
    logger.info(JSONObject.toJSONString(response.getBody()));
    return (JSONObject) JSONObject.toJSON(response.getBody());
}

2、post请求

@PostMapping("/batchAddCart")
public JSONObject addCart(@RequestParam Map<String,Object> params){
    HttpHeaders requestHeaders = new HttpHeaders();
    requestHeaders.add("Authorization","Bearer "
    + String.valueOf(params.get("access_token")));
    MultiValueMap<String, Object> entryRecordParam = 
    new LinkedMultiValueMap<String, Object>();
    entryRecordParam.add("yzOpenId",params.get("yzOpenId"));
    entryRecordParam.add("cartParams",params.get("cartParams"));
    HttpEntity<MultiValueMap<String, Object>> requestEntity = 
    new HttpEntity<MultiValueMap<String, Object>>(entryRecordParam, requestHeaders);
    ResponseEntity<Map> response = null;
    try {
        response = restTemplate.exchange(yzymUrl+"/app/yzGoods/batchAddCart",         HttpMethod.POST, requestEntity, Map.class);
    }catch (Exception e){
        return exceptionObj(e.getMessage());
    }
    logger.info(JSONObject.toJSONString(response.getBody()));
    return (JSONObject) JSONObject.toJSON(response.getBody());
}
