Spring boot : delegateBuilder cannot be null on autowiring authenticationManager in custom UserDetailsService - java

Hi i'm new to spring boot and trying implement the security to my rest apis.
i'm using spring boot 2.0.7.release
i have configures my WebSecurityConfig as following
#Configuration
#EnableWebSecurity
#EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
#Resource(name = "userService")
private UserDetailsService userDetailsService;
#Bean
#Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
#Autowired
public void globalUserDetails(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService)
.passwordEncoder(encoder());
}
#Bean
public JwtAuthenticationFilter authenticationTokenFilterBean() throws Exception {
return new JwtAuthenticationFilter();
}
#Bean
public PasswordEncoder encoder(){
PasswordEncoder encoder = new CustomPasswordEncoder();
return encoder;
}
....
}
I have add the resource name so that i can point the to custom userDetailsService.
I have tried configuring authenticationManager Bean by came and pointing the bean by Qualifier authenticationManager bean still it the error remains same.
my pom.xml looks like for security
......
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
......
and my implemented UserServiceImpl is
#Service(value = "userService")
public class UserServiceImpl implements UserService, UserDetailsService {
#Autowired
private UserDAOService userDao;
#Autowired
private AuthenticationManager authenticationManager;
#Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
User user = userDao.findByUsername(username);
if(user == null){
throw new UsernameNotFoundException("Invalid username or password.");
}
return new org.springframework.security.core.userdetails.User(user.getEmail(), user.getPassword(), getAuthority());
}
#Override
public String login(LoginUser user) {
// valid user if it exits then do the following
authenticationManager.authenticate(
new UsernamePasswordAuthenticationToken(user.getUsername(), user.getPassword()));
//generate the token and do other process.
}
following are the error logs. i have provided only mail errors

In order to help you better, it is better if you indicate which reference you are following to implement JWT mechansim.
Conceptually, this part of the source code is wrong:
#Override
public String login(LoginUser user) {
// valid user if it exits then do the following
authenticationManager.authenticate(
new UsernamePasswordAuthenticationToken(user.getUsername(), user.getPassword()));
//generate the token and do other process.
}
See if the modifications below can help you
1) Consider using Java Config to declare your beans, in a seperate Configuration class
#Configuration
public class ServiceConfig{
#Bean
protected UserDAOService daoService()
{
return new UserDAOServiceImpl();
}
#Bean
protected UserDetailsService userDetailService( UserDAOService dao )
{
return new UserServiceImpl( dao );
}
#Bean
public PasswordEncoder encoder(){
PasswordEncoder encoder = new CustomPasswordEncoder();
return encoder;
}
#Bean
public JwtAuthenticationFilter authenticationTokenFilterBean() throws Exception{ {
return new JwtAuthenticationFilter();
}
}
2) Modification to your WebSecurityConfig
#Configuration
#EnableWebSecurity
#EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
#Autowired
private UserDetailsService userDetailsService;
#Autowired
private PasswordEncoder passwordEncoder;
#Override
protected void configure( AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService( userDetailsService ).passwordEncoder( passwordEncoder );
}
}

I'm trying to upgrade Spring Security from 5.8 to 6.0. Here's the old version of the WebSecurityConfig class:
#Configuration
#ImportResource( "classpath:spring-ui-security-config.xml" )
#EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
#Autowired
DaoAuthenticationProvider daoAuthenticationProvider;
#Override
protected void configure( AuthenticationManagerBuilder auth ) {
auth.authenticationProvider( daoAuthenticationProvider );
}
#Override
protected void configure( HttpSecurity http ) throws Exception {
http
.requiresChannel()
.anyRequest()
.requiresSecure();
}
}
And the new version:
#Configuration
#ImportResource( "classpath:spring-ui-security-config.xml" )
#EnableWebSecurity
public class WebSecurityConfig {
#Autowired
DaoAuthenticationProvider daoAuthenticationProvider;
#Bean
public SecurityFilterChain securityFilterChain( HttpSecurity http ) throws Exception {
http
.requiresChannel()
.anyRequest()
.requiresSecure()
.and()
.authenticationProvider( daoAuthenticationProvider );
return http.build();
}
}
When I try to run the app, I get the following error:

Spring boot security - Cannot autowire service in web security config with custom Authentication Provider

First of all I have two projects: core where I have DTOs, Services and DAOs, and admin that is just for Web Services. Web services works perfect against data base, but now I'm trying to use Spring Security with a custom Authentication Provider against data base, but when deployed got

Unresolved circular reference when trying to deploy a spring boot war to tomcat8?

I am new to spring and trying to create a web app using spring boot and jsp which I can deploy using tomcat8 on a raspberry pi. I can deploy my app through sts on an embedded tomcat instance and I can also deploy a war file to Jenkins without any errors. However, when I add the war to tomcat8 webapps folder and start tomcat I get the following error:

I have tried annotating my configuration class with #Lazy and added setter methods to my userServiceImpl class but I still got the issue. Any help would be greatly appreciated?

I think you should go through Spring Reference about IoC container.
WebSecurityConfig class requires UserDetailsService, which is implemented by UserServiceImpl. Also, UserServiceImpl requires PasswordEncoder which is provided by WebSecurityConfig. This causes a circular reference. Removing constructor injection should be enough to resolve your problem.
Side note: Try not to use constructor injection. Spring is clever when it comes to DI, but if you use constructor injection you are forcing spring to use your way. This can also cause circular reference errors.
I recommend you to at least skim this article: https://steveschols.wordpress.com/2012/06/05/i-was-wrong-constructor-vs-setter-injection/

Integrating Spring boot with Spring Security

Here's my application class.
#SpringBootApplication
#ComponentScan({"org.app.genesis.client.controller","org.app.genesis.commons.service",
"org.app.genesis.commons.security","org.app.genesis.inventory.service","org.app.genesis.client.auth"})
#EnableJpaRepositories(basePackages = "org.app.genesis.*.repo")
#EntityScan(basePackages = "org.app.genesis.*.model")
public class Application extends SpringBootServletInitializer {
public static void main(String[] args) {
ApplicationContext ctx = SpringApplication.run(Application.class, args);
}
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
..other configs here
#Configuration
#EnableWebSecurity
#ComponentScan({"org.app.genesis.client.auth"})
public class SecurityConfig extends WebSecurityConfigurerAdapter {
#Autowired
private AuthenticationProvider customAuthProvider;
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(customAuthProvider);
}
}
}
However whenever I build the app. it always throw this exception
[ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:1.2.3.RELEASE:run (default-cli) on project app-client-webapp: An exception occured while running. null:

EDIT: New Spring Security Config
#Configuration
#EnableWebSecurity
#Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
protected static class SecurityConfig extends WebSecurityConfigurerAdapter {
#Autowired
#Qualifier("customAuthenticationProvider")
private AuthenticationProvider customAuthProvider;

.permitAll().and().csrf().disable();
}
}
Complete code is missing because of which I can't pin point the line which is causing this issue but I will definitely make an attempt to explain it, so that you can fix it yourself
#EnableWebSecurity
The JavaDoc documentaion:
Add this annotation to an #Configuration class to have the Spring
Security configuration defined in any WebSecurityConfigurer or more
likely by extending the WebSecurityConfigurerAdapter base class and
overriding individual methods.
It seems like either you missed to override "configure" method of WebSecurityConfigurerAdapter base class or didn't implemented the "configureGlobal" method correctly or you may want to create a class extends AbstractSecurityWebApplicationInitializer, it will load the springSecurityFilterChain automatically.
However I suggest you to go through the following sources and you should be able to figure out what is that you are missing.
https://github.com/spring-projects/spring-security-oauth-javaconfig/blob/master/samples/oauth2-sparklr/src/main/java/org/springframework/security/oauth/examples/sparklr/config/SecurityConfiguration.java

Spring Autowiring Beans giving Class Cast Exception

Here is my class
#Configuration
class MongoDBConfig {
private Logger logger = LoggingFactory.getLogger(getClass());
#Bean
#Scope(value = "singleton", proxyMode = ScopedProxyMode.INTERFACES)
public MongoClient mongoClient() throws UnknownHostException {
logger.error("In Dev mode:");
return new MongoClient("fctest");
}
#Bean
public DB mongoDB() throws UnknownHostException{
try {
return mongoClient().getDB(FCProperties.MONGO_DB_NAME);
}catch (UnknownHostException ue){
logger.error("Error occurred: "+ue.getMessage());
throw ue;
}
}
}
And here is how I'm using it -
public class UserRepository extends BaseRepository {
#Autowired
public UserRepository(DB mongoDB) {
super("users", mongoDB);
}
}
I'm getting the following error
Error creating bean with name 'mongoDB' defined in class path resource [com/fctest/mongo/config/MongoDBConfig.class]: Instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Factory method [public com.mongodb.DB com.fctest.mongo.config.MongoDBConfig.mongoDB() throws java.net.UnknownHostException] threw exception; nested exception is java.lang.ClassCastException: com.sun.proxy.$Proxy13 cannot be cast to com.mongodb.MongoClient
