I have to create a new rest service, the problem is my service never answer and never logs.
On the the same app I have this following service class which works properly.
I mean on the browser (under this url http://localhost:8080/IMEL/resources/hello ) answers correctly "Hello from IMEL Rest service!"
package it.sella.imel.api.rest;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import org.springframework.stereotype.Service;
#Service
#Path("/hello")
public class HelloService {
#GET
#Produces({MediaType.TEXT_PLAIN})
public String hello() {
return "Hello from IMEL Rest service!";
}
}
While my new service doesn't log and responds (at this url http://localhost:8080/IMEL/resources/listapwg ) the following error "{"status":"EXPECTATION_FAILED","errorMessage":"HTTP 404 Not Found"}"
package src.main.java.it.sella.imel.api.rest;
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;

import org.springframework.stereotype.Service;

import it.sella.util.Log4Debug;
import it.sella.util.Log4DebugFactory;
import it.sella.imel.api.log.Logged;
#Service
#Logged
#Path("/listapwg")
public class ListaPWG {
private static Log4Debug log4Debug = Log4DebugFactory.getLog4Debug(ListaPWG.class);
#GET
#Produces({MediaType.TEXT_PLAIN})
public String helloListaPWG() {
log4Debug.debug("sono in helloListaPWG GET");
return "Hello from IMEL Rest service!";
}
#POST
#Produces({ MediaType.APPLICATION_JSON })
public Response fetchListaPWG(#QueryParam("dataQuadratura") String dataQuadratura, #Context UriInfo uriInfo) {
log4Debug.debug("sono in fetchListaPWG POST");
... do some other stuff ...
return Response.status(Response.Status.OK).entity(entity).build();
}
}
obviously maven compiles correctly...
the only difference I see is the Logged class, but within or without, in any case it won't work, that's why I don't think that is the problem.
package it.sella.imel.api.log;
import static java.lang.annotation.RetentionPolicy.RUNTIME;
import java.lang.annotation.ElementType;

import java.lang.annotation.Target;
import javax.ws.rs.NameBinding;

public #interface Logged {

I don't understand what is the problem. Its my first spring-boot application please help.
I have the following Spring Boot Controller:
import java.io.InputStream;
import javax.servlet.http.HttpServletRequest;
import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.QueryParam;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import com.att.aft.dme2.internal.javaxwsrs.PUT;
import com.att.bttw.model.HelloWorld;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import io.swagger.annotations.ApiResponse;
import io.swagger.annotations.ApiResponses;
#Api
#Path("/service")
#Produces({ MediaType.APPLICATION_JSON })
public interface RestService {
#PUT
#Path("/datarouter/{filename}")
#Consumes("application/gzip")
#Produces(MediaType.APPLICATION_JSON)
Response testEndpoint(#Context HttpServletRequest request, #PathParam("filename") String filename, InputStream inputStream);
}
The implementation of this method is simply:
import javax.servlet.http.HttpServletRequest;
import javax.ws.rs.core.Response;
import org.springframework.stereotype.Component;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.client.RestTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;

import com.att.bttw.model.CountsDataModel;
import com.att.bttw.model.CountsDataResults;
import com.att.bttw.model.DisplayFieldRecord;
import com.att.bttw.model.DisplayRecord;
import com.att.bttw.model.WatermarkEventObject;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import java.io.IOException;
import java.io.InputStream;
import java.sql.Timestamp;
import java.time.Instant;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.stream.Collectors;
#Override
public Response testEndpoint(HttpServletRequest request, String filename, InputStream inputStream) {
System.out.println("File name consumed: " + filename);
return null;
}
When I try to hit this endpoint, I get the following error:
"Following issues have been detected: Response testEndpoint(javax.servlet.http.HttpServletRequest, java.lang.String, java.io.InputStream), can not have an entity parameter. Try to move the parameter to the corresponding resource method".
When I remove the InputStream and HttpServletRequest parameters, the endpoint works just fine, I'm just not understanding the error message I'm getting.
Im trying to mock a controller's post method. I want it to return status code 201(CREATED) . But it gives Status Code 200.
Given below is the code
This is my controller Class
package com.example.demo;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RestController;
public #RestController
class SomeController{
#PostMapping("/insertString")
public ResponseEntity<String> insertString(String str) {
return new ResponseEntity<>(new String("monster"),HttpStatus.CREATED);
}
}
This is my junit test Suit
package com.example.demo;
import static org.junit.Assert.*;
import static org.mockito.Mockito.when;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;
import static org.mockito.Mockito.anyString;

import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.MvcResult;
import org.springframework.test.web.servlet.RequestBuilder;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RestController;
#RunWith(SpringRunner.class)
#WebMvcTest(SomeController.class)
public class TestClass {
#Autowired
private MockMvc mockMvc;
#MockBean
private SomeController someController;
#Test
public void test() throws Exception {
ResponseEntity<String> entity = new ResponseEntity<>(HttpStatus.CREATED);
when(someController.insertString(anyString())).thenReturn(entity);
RequestBuilder requestBuilder = MockMvcRequestBuilders
.post("/insertString")
.accept(MediaType.APPLICATION_JSON)
.content("monkey")
.contentType(MediaType.APPLICATION_JSON);
MvcResult result = mockMvc.perform(requestBuilder)
.andExpect(status().isCreated())
.andReturn();
System.out.println(result.getResponse().getContentAsString());
}
}
The errorim getting is
java.lang.AssertionErrror:Status expected:<201> but was:<200>
Though i have mentioned the status as HttpStatus.CREATED in the RequestEntity object, Why am i getting 200.
Please if someone can help
Try to change
public ResponseEntity<String> insertString(String str)
to
public ResponseEntity<String> insertString(#RequestBody String str)

This is the old, Hadoop 1 API
import org.apache.hadoop.mapred.*;
You should be importing from classes within
org.apache.hadoop.mapreduce.*;
As the error says
not org.apache.hadoop.mapreduce.Mapper
So, basically, you don't need MapReduceBase, and Mapper is a class now, not an interface
So, you now would have
public static class MyMapper extends Mapper<Kin, Vin, Kout, Vout>
