使用 JSON 的 Spring MVC RestTemplate POST
我有一个 Spring MVC Rest 控制器，它只是添加一个客户记录。我的 Rest 服务传递 JSON，并且当我从 Web 客户端或像 Soap-UI 这样的测试台调用它时工作正常。但是，当我尝试使用 RestTemplate 进行 POST 时，出现 JacksonMappingException：无法构造 CustomerObject 实例，问题：找不到合适的创建者方法。
这显然与我创建 JSON 请求的方式有关，因此我正在做的就是添加一些内容：
我的测试帖子使用 RestTemplate
@Test
public void postCustomerIntegrationTest() throws Exception{
String JSONInput = ("{" +
" \"firstName\": \"Anouska\"," +
" \"lastName\": \"Williams\"," +
" \"email\": \"[email protected]\"," +
" \"cardBin1\": 123456768," +
" \"cardBin2\": 123456789," +
" \"language\": \"Spanish\"," +
" \"country\": \"Mexico\"," +
" \"product\": \"shit\"," +
" \"telephoneNumber\": 447869995262," +
" \"termsAndConditions\": \"true\"" +
"}");
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
HttpEntity request= new HttpEntity(JSONInput, headers);
Registration output = restTemplate.postForObject(BASE_URL, request, CustomerObject.class);
assertNotNull("no person",output);
assertNotNull(output.getId());
assertEquals("Bob", output.getFirstName());
}
我的 RestTemplate 通过 Spring 进行连接，如下所示：
<bean id="restTemplate" class="org.springframework.web.client.RestTemplate">
<property name="messageConverters">
<list>
<bean id="jsonConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
<property name="supportedMediaTypes" value="application/json" />
</bean>
</list>
</property>
</bean>
我的测试 JSON这里使用的与我在 Soap-UI 中使用的测试 JSON 相同。调试完代码后，它看起来像是将我的 JSON 视为字符串，而 Jackson 正在尝试转换整个内容，因为它找不到关联的字段（当然它找不到）。
我想我需要知道如何将 JSON 传递到 RestTemplate，以便以正确的 JSON 格式获取请求。我花了一上午的时间试图找到一个例子，但在任何地方都找不到。
非常感谢您的帮助。
I have a Spring MVC Rest Controller that simply adds a customer record. My Rest Service passes around JSON and works fine when I call it from a web client or a test bed like Soap-UI. However, when I try to POST using RestTemplate I get a JacksonMappingException: Can not construct instance of CustomerObject, problem: no suitable creator method found.
It's clearly something to do with the way I am creating the JSON request so to add some meat to the bones here is what I'm doing:
My Test posts using RestTemplate
@Test
public void postCustomerIntegrationTest() throws Exception{
String JSONInput = ("{" +
" \"firstName\": \"Anouska\"," +
" \"lastName\": \"Williams\"," +
" \"email\": \"[email protected]\"," +
" \"cardBin1\": 123456768," +
" \"cardBin2\": 123456789," +
" \"language\": \"Spanish\"," +
" \"country\": \"Mexico\"," +
" \"product\": \"shit\"," +
" \"telephoneNumber\": 447869995262," +
" \"termsAndConditions\": \"true\"" +
"}");
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
HttpEntity request= new HttpEntity(JSONInput, headers);
Registration output = restTemplate.postForObject(BASE_URL, request, CustomerObject.class);
assertNotNull("no person",output);
assertNotNull(output.getId());
assertEquals("Bob", output.getFirstName());
}
My RestTemplate is wired through Spring as follows:
<bean id="restTemplate" class="org.springframework.web.client.RestTemplate">
<property name="messageConverters">
<list>
<bean id="jsonConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
<property name="supportedMediaTypes" value="application/json" />
</bean>
</list>
</property>
</bean>
The test JSON I'm using here is the same as the test JSON I use in Soap-UI. Having debuged the code it looks like it is treating my JSON as a String and Jackson is trying to convert the entire thing because it can't find an assiciated field (which of course it can't).
I guess I need to know how to pass JSON to my RestTemplate in such a way that the request will be picked up in the correct JSON format. I've spent all morning trying to find an example and can't find one anywhere.
Many Thanks for your help.

至少有一个问题，最后一个参数应该是响应的类别
There is at least one problem, last parameter should be class of response
这是我发布 josn 的方式：
CustomerObject 类必须有字段：firstName、lastName...
This is my way to post josn:
And CustomerObject class must have fields: firstName, lastName...
