I have the following code:

import org.springframework.web.context.annotation.RequestScope;
#RestController
public class HelloWorldController {
#GetMapping("/")
public ResponseEntity<String> getGet(
#Autowired Foo foo) {
foo.sayHi();
return new ResponseEntity<>("OK", HttpStatus.OK);
}
}
#Component
#RequestScope
class Foo {
private #Autowired HttpServletRequest request;
public void sayHi() {
var name = this.request.getHeader("x-user-name");
System.out.println("Hi " + name);
}
}
When I try to curl with curl -H x-user-name:capybara http://localhost:8080, the following error is produced:

Why is this.request null? Giving the popularity of https://stackoverflow.com/a/3324233/2287586, seems like this should work, what am I missing?
It doesn't work becuse it needs to be a Singleton bean and you have #RequestScope.
Maybe try this:
((ServletRequestAttributes)RequestContextHolder.getRequestAttributes()).getRequest();

I started with a spring boot starter project version 2.3.5, but when I call authenticationManager.authenticate I get a stack overflow error.

Initially I did not use the user variable and instead created created the new UsernamePasswordAuthenticationToken inside the authenticationManager.authenticate either way I get the stack overflow error. I also have tried #PostMapping instead of #RequestMapping and Method. All of these cause the same failure.
I get the printline that says I am "in /Authenticate" with the following.

My Spring Boot program is compiling without any issues, but whenever I click the registration link it throws NullPointerException error. I am really at a loss as to what may be causing this. Given below is the error:-
java.lang.NullPointerException: null

The UserinfoController class is given below:-
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import com.concretepage.entity.ProjectLevel;
import com.concretepage.service.LevelService;
import com.concretepage.service.UserInfoService;
#Controller
#RequestMapping("app")
public class UserInfoController {
#Autowired
private UserInfoService userInfoService;
private LevelService levelService;
#GetMapping("login")
public ModelAndView login() {
ModelAndView mav = new ModelAndView();
mav.setViewName("custom-login");
return mav;
}
#GetMapping("registration")
public ModelAndView registration() {
ModelAndView mav = new ModelAndView();
List<ProjectLevel> levels = levelService.getAllLevels();
mav.addObject("Levels", levels);
mav.setViewName("registration");
return mav;
}
#GetMapping("secure/project-details")
public ModelAndView getAllUserProjects() {
ModelAndView mav = new ModelAndView();
mav.addObject("userProjects", userInfoService.getAllUserProjects());
mav.setViewName("projects");
return mav;
}
Error is at the line -
List<ProjectLevel> levels = levelService.getAllLevels();
The LevelServiceImpl class is as below:-
package com.concretepage.service;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.concretepage.entity.ProjectLevel;
import com.concretepage.repositories.LevelRepository;
#Service
public class LevelServiceImpl implements LevelService {
#Autowired
private LevelRepository levelRepository;
#Override
public List<ProjectLevel> getAllLevels() {
List<ProjectLevel> levelList = levelRepository.findAll();
return levelList;
}
}
Just change this piece of code:
#Autowired
private UserInfoService userInfoService;
private LevelService levelService;
to
#Autowired
private UserInfoService userInfoService;
#Autowired
private LevelService levelService;
You must use separate #Autowired for private LevelService levelService;
I have run into a strange problem. I created a project with Spring Boot 2.0.1 with redis, mongodb and elasticsearch . Before adding elasticsearch, everything runs smoothly, but after I add elasticsearch, Spring Boot starts complaining，but the error looks like not related to elasticsearch, it complains that it could not create userRepo 。 Please get noticed I used lombok's #RequiredArgsConstructor to generate constructor to make injection work, so it should not be #autowired issue, Anyone can help me out? thank in adavance

It turns out I reuse same entities for both Elasticsearch and MongoDB, which raise the exception. So I managed to get it resolved by separating the entities

Your "FacebookController" doesn't have a Default Constructor public FacebookController() and Spring needs it to create a new bean. When you declare you constructor public FacebookController(Facebook facebook), you're telling to Spring that the only existing constructor receives a parameter.
You can let you default Constructor like
#Autowire
private Facebook facebook;
public FacebookController() { }
