Issue
i am having trouble while developing web application using spring boot
i am applying spring security and having errors i dont know how to solve the error im also new at spring boot and first time using spring security my credentials are not been accessed by the compiler and having issues
this is my dao class
package com.voicechat.dao;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.query.Param;
import com.voicechat.entities.Credentials;
import com.voicechat.entities.Robi_nav;
public interface Robi_Dao_logIn extends JpaRepository<Credentials, Integer> {
@Query("select c from Credentials c where c.uname = :uname")
public Robi_Dao_logIn getbyUname(@Param("uname") String uname);
}
this is my credentials class
package com.voicechat.entities;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name = "credentials")
public class Credentials {
@GeneratedValue
@Id
private int Id;
private String uname;
private String password;
private String role;
public int getId() {
return Id;
}
public void setId(int id) {
Id = id;
}
public String getUname() {
return uname;
}
public void setUname(String uname) {
this.uname = uname;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getRole() {
return role;
}
public void setRole(String role) {
role = role;
}
public Credentials(int id, String uname, String password, String role) {
super();
Id = id;
this.uname = uname;
this.password = password;
role = role;
}
public Credentials() {
super();
// TODO Auto-generated constructor stub
}
}
i am applying spring security here so this is my Custom user Details class
package com.voicechat.config;
import java.util.Collection;
import java.util.List;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import com.voicechat.entities.Credentials;
public class CustomUserDetails implements UserDetails {
private Credentials cred;
public CustomUserDetails(Credentials cred) {
super();
this.cred = cred;
}
@Override
public Collection<? extends GrantedAuthority> getAuthorities() {
SimpleGrantedAuthority simple = new SimpleGrantedAuthority(cred.getRole());
return List.of(simple);
}
@Override
public String getPassword() {
return cred.getPassword();
}
@Override
public String getUsername() {
return cred.getUname();
}
@Override
public boolean isAccountNonExpired() {
// TODO Auto-generated method stub
return true;
}
@Override
public boolean isAccountNonLocked() {
// TODO Auto-generated method stub
return true;
}
@Override
public boolean isCredentialsNonExpired() {
// TODO Auto-generated method stub
return true;
}
@Override
public boolean isEnabled() {
// TODO Auto-generated method stub
return true;
}
}
this is my config class
package com.voicechat.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.dao.DaoAuthenticationProvider;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
@Configuration
@EnableWebSecurity
public class MyConfig extends WebSecurityConfigurerAdapter {
@Bean
public UserDetailsService getUserDetailService() {
return new UserDetailsServiceImpl();
}
@Bean
public BCryptPasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
@Bean
public DaoAuthenticationProvider provider() {
DaoAuthenticationProvider daoautpro = new DaoAuthenticationProvider();
daoautpro.setUserDetailsService(this.getUserDetailService());
daoautpro.setPasswordEncoder(passwordEncoder());
return daoautpro;
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(provider());
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests().antMatchers("//**").hasRole("ADMIN").and().formLogin().and()
.csrf().disable();
}
}
and this is my implementation class of user details
package com.voicechat.config;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import com.voicechat.dao.Robi_Dao_logIn;
import com.voicechat.entities.Credentials;
public class UserDetailsServiceImpl implements UserDetailsService{
@Autowired
private Robi_Dao_logIn login;
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
Credentials cred = (Credentials) login.getbyUname(username);
if (cred == null) {
throw new UsernameNotFoundException("User Not Found");
}
CustomUserDetails custom=new CustomUserDetails(cred);
return custom;
}
}
i am having this error
org.springframework.security.authentication.InternalAuthenticationServiceException: class com.sun.proxy.$Proxy93 cannot be cast to class com.voicechat.entities.Credentials (com.sun.proxy.$Proxy93 and com.voicechat.entities.Credentials are in unnamed module of loader 'app')

Solution
You have a very strange return type in your Repository class
public interface Robi_Dao_logIn extends JpaRepository<Credentials, Integer> {
@Query("select c from Credentials c where c.uname = :uname")
public Robi_Dao_logIn getbyUname(@Param("uname") String uname);
}
It should return Credentials instead of Robi_Dao_logIn.
