LazyInitializationException：未能延迟初始化角色集合：Usuario.autorizacoes，无法初始化代理 - 无会话

Question

在我的 spring 应用程序中，我实现了一个自定义的 AuthenticationProvider，它使用了 处理我的登录申请的服务。 AuthenticationProvider 如下：

https://github.com/klebermo/webapp_horario_livre/blob/master/src/com/horariolivre/security/CustomAuthenticationProvider.java

我的服务等级是：

https://github.com/klebermo/webapp_horario_livre/blob/master/src/com/horariolivre/service/AuthenticationService.java

当我运行应用程序时，我收到此错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'securityConfig': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.horariolivre.security.CustomAuthenticationProvider com.horariolivre.security.SecurityConfig.authenticationProvider; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'customAuthenticationProvider': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.horariolivre.service.AuthenticationService com.horariolivre.security.CustomAuthenticationProvider.authenticationService; nested exception is java.lang.IllegalArgumentException: Can not set com.horariolivre.service.AuthenticationService field com.horariolivre.security.CustomAuthenticationProvider.authenticationService to com.sun.proxy.$Proxy36

有人可以指出解决这个问题的方向吗？

===

好的，我设法解决了以下问题，将以下选项添加到我的 @EnableTransactionManagement 注释中：

(mode=AdviceMode.PROXY, proxyTargetClass=true)

现在我遇到了一个新错误，现在在我的 AuthenticationService 类中，代码是：

https://github.com/klebermo/webapp_horario_livre/blob/master/src/com/horariolivre/service/AuthenticationService.java

错误是：

我该如何解决这个新错误？

Answer 1

好的，我解决了本主题中指出的所有问题。我在 AuthenticationService 中的最终代码是：

@Override
    @Transactional(readOnly = true, propagation = Propagation.SUPPORTS)
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        Usuario account = accountDao.findByUsername(username);

        if(account == null) {
            throw new UsernameNotFoundException("No such user: " + username);
        }

        List<Autorizacoes> auth = account.getAutorizacoes();

        if(auth.isEmpty()) {
            throw new UsernameNotFoundException("User " + username + " has no authorities");
        }

        boolean accountNonExpired = true;
        boolean credentialsNonExpired = true;
        boolean accountNonLocked = true;
        boolean accountEnabled = true;

        return new User(account.getLogin(), account.getSenha(), accountEnabled, accountNonExpired, credentialsNonExpired, accountNonLocked, getAuthorities(account.getAutorizacoes()));
    }

在我的 Entity 类中，我将属性 Autorizacoes 声明为：

@ManyToMany(cascade=CascadeType.ALL, fetch = FetchType.EAGER)
    @JoinTable(name = "autorizacoes_usuario", joinColumns = { @JoinColumn(name = "fk_usuario") }, inverseJoinColumns = { @JoinColumn(name = "fk_autorizacoes") })
    //@LazyCollection(LazyCollectionOption.TRUE)
    public List<Autorizacoes> getAutorizacoes() {
        return this.autorizacoes;
    }

Answer 2

可能错误在于您的 Service 中的 UserHome 注入。

@Autowired
private UsuarioHome accountDao;
