Unmarshaling (JSON) in apache camel

Unmarshaling (JSON) in apache camel - java

I am new in apache camel. And I wanna do some simple task using apache camel. I have json data available on this url http://localhost:8080/users/. There are json data from my rest service. But I wanna get this json data and unmarshal it to POJO using apache camel and write some data to txt file. But my app starts and then doesnt't stop.
Here is my JSON data available on http://localhost:8080/users/
[{"id":1,"login":"admin","password":"admin","passwordAgain":null,"email":"admin#admin.com","firstName":"Admin","lastName":"Adminovich","birthday":"2010-10-10","role":{"id":1,"name":"admin"}},
{"id":5,"login":"Snow123","password":"1111","passwordAgain":null,"email":"john#snow.com","firstName":"John","lastName":"Snow","birthday":"2010-10-10","role":{"id":2,"name":"user"}}]

In my case I converted JsonData to Java object and created a custom CSV file using following dependencies.
jackson-mapper-asl
jackson-core-asl
You can create simple text file or CSV whatever it is.
This is my route:
from("couchdb:http://localhost:5984/order")
.startupOrder(1)
.process(new JsonToCsvProcessor())
.to("file:/home/r2/Desktop/ofBizFile?fileExist=append&fileName=orders-${date:now:dd-MM-yyyy}.csv");
This is my Processor where I am passing JsonString to ObjectMapper for Pojo:
{
public void process(Exchange exchange)throws Exception{
String jsonString = exchange.getIn().getBody(String.class);
exchange.getOut().setBody(convertJsonToCSV(jsonString).toString());
}
public StringBuilder convertJsonToCSV(String jsonStringArgs){
StringBuilder csvFile = new StringBuilder();
//Here customize data format using append()
.
.
return csvFile;
}
}
If you don't know how to use ObjectMapper this link will help you out.
https://www.youtube.com/watch?v=02X6U81MdJ0&t=1s

Use one of the amounts in json's case: Jackson or Gson
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-jackson</artifactId>
<version>${camel.version}</version>
</dependency>
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-gson</artifactId>
<version>${camel.version}</version>
</dependency>
I recommend checking the documentation
you can do the unmarshal direct on the route:
unmarshal().json(JsonLibrary.Jackson, MyModel.class)
or you can create a processor:
#Component
public class MyModelUnMarshalProccessor implements Processor {
#Override
public void process(Exchange exchange) throws Exception {
MyModel model = exchange.getIn().getBody(MyModel.class);
exchange.getOut().setBody(model);
exchange.getOut().setHeader("id", body.getId());
}
}
#Autowired
MyModelUnMarshalProccessor myModelUnMarshalProccessor;
from("{{fromServices}}")
.log("${body}")
.process(myModelMarshalProccessor)
good luck

retrieve of email and password from MySql databse using springboot

I want retrieve user email from MySql database table using spring boot.i used findByEmailAndPassword in controller but it retrieve null value for email.
Here is my Code
controller
package com.example.demo.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import com.example.demo.JPARepository;
import com.example.demo.pojo.regisbean;
#Controller
public class registerController {
regisbean pp;
#RequestMapping(value = "/")
public String mm() {
System.out.println("I am in m1 method");
return "index";
}
#RequestMapping(value = { "/register", "home" })
public String m1() {
System.out.println("I am in mm method");
return "register";
}
#Autowired
JPARepository jpaRepository;
#PostMapping("/register")
public String regis(#ModelAttribute regisbean rb)
{
System.out.println("I m in regis method");
regisbean b=jpaRepository.save(rb);
if(b!=null)
return "index";
else
return "fail";
}
#RequestMapping(value= {"/login1","login2"})
public String m2() {
System.out.println("i m in m2()");
return "login";
}
#PostMapping("/login")
public String login(#ModelAttribute regisbean rx,Model m) {
System.out.println("I am in Login");
regisbean re=jpaRepository.findByEmailAndPassword(rx.getEmail(), rx.getPassword());
if(re!=null)
{
m.addAttribute("email",rx.getEmail());
m.addAttribute("password",rx.getPassword());
System.out.println("yes");
return "loginsuccess";
}
else
{
System.out.println(rx.getEmail());
System.out.println("failed");
return "register";
}
}
}
pojo class
package com.example.demo.pojo;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
#Entity
#Table(name = "pro")
public class regisbean {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private int id;
#Column
private String name;
#Column
private String email;
#Column
private String phonenumber;
#Column
private String password;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {

}
public void setName(String name) {
this.name = name;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getPhonenumber() {
return phonenumber;
}
public void setPhonenumber(String phonenumber) {
this.phonenumber = phonenumber;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
Repository
package com.example.demo;
import org.springframework.data.repository.CrudRepository;
import com.example.demo.pojo.regisbean;
public interface JPARepository extends CrudRepository<regisbean, Integer> {
public regisbean findByEmailAndPassword(String email,String password);
}

I was able to get your code to work by inserting a row in the table:
INSERT INTO pro (
id
,email
,name
,password
,phonenumber
)
VALUES (
0
,'user#domain.com'
,'Jim'
,'secret'
,'123-123-1234'
)
Then changing:
public String login(#ModelAttribute regisbean rx,Model m) {
to:
public String login(#RequestBody RegisBean rx,Model m) {
and POSTing the following request body to the /login resource:
{
"email": "user#domain.com",
"password": "secret"
}
I didn't have to make any changes to your Repo. I suspect your attempt was failing because RegisBean was never being initialized with any values and so the repo was asked to find a record with a null email and a null password.

Login Issue in Spring Boot using spring boot security

I am new to spring boot, and I'm trying spring boot security on my sample application and i'm using MongoDB.
I'm facing some issue. I'm using POSTMAN to test the web services that I developed.
I am not able to hit login method using POSTMAN.

When i hit localhost:8080/login in POSTMAN with POST method (username and password as mentioned in UserTbl), it says

"status": 404,
"error": "Not Found",
"message": "No message available",
"path": "/login"
}
My application.properties file
spring.data.mongodb.database=web_application

Please check once if you have defined different context explicitly in your application.properties file.
Spring Boot 1.X
server.contextPath=/yourAppContext
server.port=8080
Spring Boot 2.0
server.servlet.contextPath=/yourAppContext
If so, you would need to add context path to your request URL,
like ,
localhost:8080/yourAppContext/login

JAX-RS REST API Basic Authentication

i am trying to implement basic authentication to somehow secure my rest api.To test, i tried below code to filter the url parameter that contains users however it is not aborting the request without authorization. and the most important is i need to implement it in the way that only update and delete needs to be authorized with the respective username and password. other things i just don't want to filter. i have an user class having username and password (encrypted) properties. so if the url contains PUT or delete method on users/{userID} i want it to verify with the username and password of that specific users. i have listed code of model , resources and filter class below.. i really need your help. thanks in advance.
filter class.

Basic authentication is part of the servlet specification. So if you run in a servlet container, which is the case, you can just enable basic authentication in the web.xml:

You must also configure the realm, and the roles, this depend on your servlet container implementation.

If you are running you app in a Java EE Container you can use standard web security defined in web.xml
https://docs.oracle.com/javaee/7/tutorial/security-webtier002.htm#GKBAA
Or if you use Spring
https://spring.io/guides/gs/securing-web/

In a sample jax rs api, I implemented basic authentication by getting the HttpServletRequest in my rest resource.
I created a doAuthorize() method which extract the Authentication header, decode and validate authentication as you have done.
Then I call doAuthorize() in the resource path methods which need it.

How to send mail with java mail by using Gmail SMTP with OAuth2 authentication?

I read the link below but I couldn't send mail with OAuth2 authentication mechanism. Can anyone give me an example about this ?
Without this authentication user have to enable less secure apps option from the gmail's security settings. But I don't want to push user to do that. That's why I need this authentication mechanism.
link: https://java.net/projects/javamail/pages/OAuth2

Given below is the working code how to send emails using OAuth2 in a web project using Spring.
Important :
First create project at Google console, after that when creating credentials at Google console remember to set
application type to other.
Use oauth2.py get access token and other required values needed for the
code. File itself has instructions on how to use it, to get required values.

Junit test doesn't persist entity with Google App Engine

I'm developing a project using GAE. I'm writing an integration test with Junit which don't save the entity. I have included the JARs in classpath and I copy here the entity class, the test class and the persistence.xml file.

#BeforeClass
public static void setUpUtenti() {
utImpl.creaUtente("Utente1", "Test1", "test1", "test1", "test1#test.it");
utImpl.creaUtente("Utente2", "Test2", "test2", "test2", "test2#test.it");

public void testCercaUtenteByEmail() {

String emailTest = "test1#test.it";
String nomeTest = "Utente1";
String cognomeTest = "Test1";
utente = utImpl.cercaUtenteByEmail(emailTest);
Assert.assertEquals(utente.getNome(), nomeTest);
Assert.assertEquals(utente.getCognome(), cognomeTest);
}
#Test
public void testLogin() {
Utente utente;
String usernameTest = "test1";
String passTest = "test1";
String nomeTest = "Utente1";
String cognomeTest = "Test1";
utente = utImpl.login(usernameTest, passTest);
Assert.assertEquals(utente.getNome(), nomeTest);
Assert.assertEquals(utente.getCognome(), cognomeTest);
}
}
The problem is that the methods setUpUtenti ad testCreaUtente don't persist the entities.
The test testListaUtenti fails because the Utenti numbers was expected 4 but is 0.

Every #Test annotated method is invoked on a freshly created instance of class. So basically you can not persist between methods. You should put this code into one method.
