RESTのURLを定義する
HelloApplication.java
package hello;
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;
@ApplicationPath("/rest")
public class HelloApplication extends Application{
}
POJOでOK
get や set は自動でランタイムがやってくれる
HelloRequest.java
package hello;
public class HelloRequest {
String message;
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}
POJOでOK
get や set は自動でランタイムがやってくれる
JSON や XML への変換も自動でランタイムがやってくれる
HelloResponse.java
package hello;
public class HelloResponse {
String message;
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}
HelloServlet.java
package hello;
import javax.ws.rs.Consumes;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
@Path("/hello")
@Produces("application/json; charset=UTF-8")
@Consumes(MediaType.APPLICATION_JSON)
public class HelloServlet {
@POST
public HelloResponse getMessage(HelloRequest request) {
try {
HelloResponse response = new HelloResponse();
response.setMessage("こんにちは");
return response;
} catch (Exception e) {
// Utils.handleException(e);
e.printStackTrace();
}
return null;
}
}
