Hi,
I tried to send a json post request to the sample microservice I built
using wso2 ms4j framework.
It works with the pojo class as in the below example (POST service/1) but
doesn't work with the String type and InputStream type.
Please refer the following java code / curl request and the error I
received.
package org.example.service;
import java.io.BufferedReader;import java.io.InputStream;import
java.io.InputStreamReader;
import javax.ws.rs.Consumes;import javax.ws.rs.GET;import
javax.ws.rs.POST;import javax.ws.rs.Path;import
javax.ws.rs.core.MediaType;
@Path("/service")public class HelloService {
@GET
@Path("/")
public String get() {
System.out.println("GET invoked");
return "Hello from WSO2 MSF4J";
}
@POST
@Path("/1")
@Consumes(MediaType.APPLICATION_JSON)
public void postOne(Stock stock) {
System.out.println("POST_1 invoked");
System.out.println(stock.getName());
}
@POST
@Path("/2")
@Consumes(MediaType.APPLICATION_JSON)
public void postTwo(String jsonbody) {
System.out.println("POST_2 invoked");
System.out.println(jsonbody);
}
@POST
@Path("/3")
@Consumes(MediaType.APPLICATION_JSON)
public void postThree(InputStream jsonData) {
StringBuilder stringData = new StringBuilder();
try {
BufferedReader in = new BufferedReader(new
InputStreamReader(jsonData));
String line = null;
while ((line = in.readLine()) != null) {
stringData.append(line);
}
} catch (Exception e) {
e.printStackTrace();
}
System.out.println("POST_3 invoked");
System.out.println(stringData.toString());
}
}
