I'm using spring-test-mvc to test my controller, but I can't find a way to print request body which is very inconvenient.
with MockMvcResultHandlers.print()
mvc.perform(put("/payment/1234")
.content("{\"amount\":2.3")
.contentType(MediaType.APPLICATION_JSON))
.andDo(print());
I found some body information but don't find the body part:
MockHttpServletRequest:
HTTP Method = PUT
Request URI = /payment/1234
Parameters = {}
Headers = {Content-Type=[application/json]}
Handler:
Type = com.restbucks.ordering.rest.PaymentResource
Method = public org.springframework.hateoas.Resource<com.restbucks.ordering.domain.Payment> com.restbucks.ordering.rest.PaymentResource.handle(com.restbucks.ordering.commands.MakePaymentCommand)
Async:
Async started = false
Async result = null
Update
After reading some source codes, it seems that I should extends MockMvcResultHandlers to add some print items?
//PrintingResultHandler.java
protected void printRequest(MockHttpServletRequest request) throws Exception {
this.printer.printValue("HTTP Method", request.getMethod());
this.printer.printValue("Request URI", request.getRequestURI());
this.printer.printValue("Parameters", getParamsMultiValueMap(request));
this.printer.printValue("Headers", getRequestHeaders(request));
// add body print?
}
Update Proof of Concept codes:
public static class CustomMockMvcResultHandlers {
public static ResultHandler print() {
return new ConsolePrintingResultHandler();
}
/**
* Have to copy this class from spring
*/
private static class ConsolePrintingResultHandler extends PrintingResultHandler {
public ConsolePrintingResultHandler() {
super(new ResultValuePrinter() {
@Override
public void printHeading(String heading) {
System.out.println();
System.out.println(String.format("%20s:", heading));
}
@Override
public void printValue(String label, Object value) {
if (value != null && value.getClass().isArray()) {
value = CollectionUtils.arrayToList(value);
}
System.out.println(String.format("%20s = %s", label, value));
}
});
}
@Override
protected void printRequest(MockHttpServletRequest request) throws Exception {
super.printRequest(request);
getPrinter().printValue("Body", getContentAsString(request));
}
private String getContentAsString(MockHttpServletRequest request) throws IOException {
BufferedReader reader = request.getReader();
StringBuilder builder = new StringBuilder();
String aux;
while ((aux = reader.readLine()) != null) {
builder.append(aux);
}
return builder.toString();
}
}
}
