Java 如何修复 Hibernate LazyInitializationException：无法延迟初始化角色集合，无法初始化代理 无会话

在我的Spring项目的自定义AuthenticationProvider中，我try 读取登录用户的权限列表，但我面临以下错误:

阅读StackOverflow中的其他主题，我理解这种情况的发生是由于框架处理这种类型的阿曲布坦的方式，但我无法找到任何解决方案.有人能指出我做错了什么，我能做些什么来修复它？

我的Custom AuthenticationProvider的代码是:

@Component
public class CustomAuthenticationProvider implements AuthenticationProvider {

    @Autowired
    private UsuarioHome usuario;

    public CustomAuthenticationProvider() {
        super();
    }

    @Override
    public Authentication authenticate(Authentication authentication) throws AuthenticationException {
        System.out.println("CustomAuthenticationProvider.authenticate");

        String username = authentication.getName();
        String password = authentication.getCredentials().toString();

        Usuario user = usuario.findByUsername(username);

        if (user != null) {
            if(user.getSenha().equals(password)) {
                List<AutorizacoesUsuario> list = user.getAutorizacoes();

                List <String> rolesAsList = new ArrayList<String>();
                for(AutorizacoesUsuario role : list){
                    rolesAsList.add(role.getAutorizacoes().getNome());
                }

                List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
                for (String role_name : rolesAsList) {
                    authorities.add(new SimpleGrantedAuthority(role_name));
                }

                Authentication auth = new UsernamePasswordAuthenticationToken(username, password, authorities);
                return auth;
            }
            else {
                return null;
            }
        } else {
            return null;
        }
    }

    @Override
    public boolean supports(Class<?> authentication) {
        return authentication.equals(UsernamePasswordAuthenticationToken.class);
    }

}

我的实体类有:
