I have a problem with my spring boot web application.
I have MainContorller class and CheckerClass.
It says, in the end, it is java.lang.NullPointerexception, but I am not sure what to do with that information.
MainController class:
package danilocongradac.webApp;
import javax.servlet.http.HttpServletRequest;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
#Controller
public class MainController {
private static CheckerClass checker = new CheckerClass();
#GetMapping(value = {"/", "/home"})
public static String mainPage() {
return "index";
}
#GetMapping(value = {"/error"})
public static String errorPage() {
return "error";
}
#GetMapping(value = {"/signIn"})
public static String inputPage() {
return "signIn";
}
#GetMapping(value = {"output"})
public static String outputPage(){
return "output";
}
#RequestMapping(value = {"/inputCheck"})
public static String inputPageCheck(HttpServletRequest req,Model m){
String email = req.getParameter("email");
String password = req.getParameter("password");
System.out.println("email: " + email);
System.out.println("password: " + password);
// checker
if(checker.check(email, password))
return "output";
return "input";
}
}
And CheckerClass:
package danilocongradac.webApp;
import java.util.ArrayList;
public class CheckerClass {
private static ArrayList<User> users;
public CheckerClass(){
users.add(new User("danilo", "congradac", "congradacd002#gmail.com", "danilo2002"));
}
public void addUser(String name, String surname, String email, String password){
users.add(new User(name, surname, email, password));
}
public boolean check(String email, String password) {
users.add(new User("danilo", "congradac", "congradacd002#gmail.com", "danilo2002"));
for(User u : users) {
if(email.equals(u.getEmail()) && password.equals(u.getPassword()))
return true;
}
return false;
}
}
And I get error message like this...
Error message is below:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mainController' defined in file [/home/danilocongradac/Documents/java/webApp/target/classes/danilocongradac/webApp/MainController.class]: Instantiation of bean failed; nested exception is java.lang.ExceptionInInitializerError

In the CheckerClass class users variable is not initialized. In constructors initialise it before using it.
public CheckerClass(){
users= new ArrayList<User>();
users.add(new User("danilo", "congradac", "congradacd002#gmail.com", "danilo2002"));

Description:
Field statusUpdateService in spring.controller.pageController required a bean of type 'service.StatusUpdateService' that could not be found.
The injection point has the following annotations:
- #org.springframework.beans.factory.annotation.Autowired(required=true)
Action:
Consider defining a bean of type 'service.StatusUpdateService' in your configuration.
this is my pageController:
package spring.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
import service.StatusUpdateService;
import spring.model.StatusUpdate;
#Controller
public class pageController {
#Autowired
private StatusUpdateService statusUpdateService;
#RequestMapping("/")
String home() {
return "app.homepage";
}
#RequestMapping("/about")
String about() {
return "app.about";
}
#RequestMapping(value = "/addstatus", method = RequestMethod.GET)
ModelAndView addstatus(ModelAndView modelAndView) {
modelAndView.setViewName("app.addstatus");
StatusUpdate statusUpdate = new StatusUpdate();
StatusUpdate latestStatusUpdate = statusUpdateService.getLatest();
modelAndView.getModel().put("statusUpdate", statusUpdate);
modelAndView.getModel().put("latestStatusUpdate", latestStatusUpdate);
return modelAndView;
}
#RequestMapping(value = "/addstatus", method = RequestMethod.POST)
ModelAndView addstatus(ModelAndView modelAndView, StatusUpdate statusUpdate) {
modelAndView.setViewName("app.addstatus");
statusUpdateService.save(statusUpdate);
StatusUpdate latestStatusUpdate = statusUpdateService.getLatest();
modelAndView.getModel().put("latestStatusUpdate", latestStatusUpdate);
return modelAndView;
}
}
and this is my StatusUpdateService:
package service;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import spring.model.StatusUpdate;
import spring.model.StatusUpdateDao;
#Service
public class StatusUpdateService {
#Autowired
private StatusUpdateDao statusUpdateDao;
public void save(StatusUpdate statusUpdate) {
statusUpdateDao.save(statusUpdate);
}
public StatusUpdate getLatest() {
return statusUpdateDao.findFirstByOrderByAddedDesc();
}
}
what can be the problem?
thank you

}
}
Your SpringBootApplication class is in the package com.example.employee but your JPA entity in package model
Therefore Spring Data JPA does not find your entites.
It is highly recomended that you put your application in a root package and all code below that root package.
For example
com.example.employee.EmployeeApplication
com.example.employee.model.Employees

I got my solution actually the problem was of version i was using rpcport
which is changed to test.rpcport for test net from bitcoind version 17.0
hence bean were not getting the connection from my localhost server causing null pointer exception.
I have a spring boot application, that is using spring security / basic authentication for developing an api interface.
The application has no DB so I set an encoder for the password that is stored in the application.yml file, encoded, in a property.
Sometimes, when I startup the application with mvn spring-boot:run, the application is not reading the username property from the yml file and sometimes instead gets data correctly.
It's strange, because I just rerun the application and the property is not working.
Someone has an idea of this?
Here it is the yml file:
security:
username: myuser
password: xxxxxxx-the-encoded-password
strenght: 8
Here it is the Spring #Configuration file :
#EnableWebSecurity
#Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
private Integer passwordStrenght;
#Value("${security.strenght:8}")
public void setPasswordStrenght(Integer passwordStrenght) {
this.passwordStrenght = passwordStrenght;
}
private String username;
#Value("${security.username}")
public void setUsername(String username) {
this.username = username;
}
private String password;
#Value("${security.password}")
public void setPassword(String password) {
this.password = password;
}
#Autowired
private ApplicationBasicAuthenticationEntryPoint authenticationEntryPoint;
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication()
.withUser(
User.builder()
.username(username)
.password(password)
.authorities("USER")
);
}
#Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder(passwordStrenght);
}
#Autowired
private AccessDeniedHandler accessDeniedHandler;
#Bean
public AccessDeniedHandler accessDeniedHandler() {
return new AccessDeniedHandlerImpl();
}
#Override

Thanks, Davide.
I faced simmilar problem. Solved by using propeties class.
You can inject #ConfgiruationProperties class here. then you get userName && password from properties.
#Scope(value = "singleton")
#ConfigurationProperties("com.custom")
#Configuration
#EnableConfigurationProperties
#Data
public class AppProperties {
private String userName;
private String password;
}
then yml:
com:
custom:
userName:
password:
#autowired AppProperties :
#EnableWebSecurity
#Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
#Autowired
AppProperties appProperties;
}
