Java 会话作用域bean的行为类似于请求作用域bean

我有会话作用域bean，它的行为就像请求作用域bean

我在SingletonBean中使用它，也许这就是为什么第二个请求is有空值的原因？ 我用来设置bean的代码： 在单例中：

@Autowired
private MyBean myBean;

@Service
public class SingletonBean {

    @Autowired
    private MyBean myBean;
// here I save the data to session scoped bean
    private void saveUser(LdapContext ctx, String principal) throws NamingException {
        Attributes attributes = getAttributes();
        myBean.setId("id");
        myBean.setName("name");
        myBean.setEmail("email");
        myBean.setTelNum("123");
        myBean.setGroups(Lists.newArrayList("one", "two"));
        myBean.setAddress("address");
    }
// here I try to read data from session scoped bean:
    @Override
    protected AuthorizationInfo queryForAuthorizationInfo(PrincipalCollection principals,
            LdapContextFactory ldapContextFactory) throws NamingException {
       // here userInfo will be null
        List<String> userInfo =  myBean.getGroups();
        SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
        for (String role : userInfo ) {
            authorizationInfo.addRole(role);
        }
        return authorizationInfo;
}

MyBean类：

@Component
@Scope(value = "session", proxyMode = ScopedProxyMode.INTERFACES)
public class MyBeanImpl implements MyBean, Serializable {

配置：

@Configuration
@ComponentScan(scopedProxy = ScopedProxyMode.INTERFACES, value = {  "my.package.with.bean" })
public class ComponentsConfig {
}

MyBean是简单的pojo。有能手和二传手。 对于第一个请求，我在该bean上设置值；对于同一类singleton中的第二个请求，我希望读取这些值，但所有值都为null。不可能有什么东西超越了这些价值观

编辑 我是如何发出请求的——这只是简单的浏览器请求，而对会话bean进行读/写的代码则放在过滤器中

这是singleton：

@Autowired
private MyBean myBean;

@Service
public class SingletonBean {

    @Autowired
    private MyBean myBean;
// here I save the data to session scoped bean
    private void saveUser(LdapContext ctx, String principal) throws NamingException {
        Attributes attributes = getAttributes();
        myBean.setId("id");
        myBean.setName("name");
        myBean.setEmail("email");
        myBean.setTelNum("123");
        myBean.setGroups(Lists.newArrayList("one", "two"));
        myBean.setAddress("address");
    }
// here I try to read data from session scoped bean:
    @Override
    protected AuthorizationInfo queryForAuthorizationInfo(PrincipalCollection principals,
            LdapContextFactory ldapContextFactory) throws NamingException {
       // here userInfo will be null
        List<String> userInfo =  myBean.getGroups();
        SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
        for (String role : userInfo ) {
            authorizationInfo.addRole(role);
        }
        return authorizationInfo;
}

}

当用户登录并通过身份验证时，我将他的详细信息保存在会话bean中。当他试图打开任何页面方法时，queryForAuthorizationInfo会在该对象中的筛选器链和值为空后执行。

请向我们展示相关的读/写代码以及您如何发出请求。您能否发布您的Singleton实现，完成MyBeanImpl类和处理请求的类？我还将添加会话id，在保存到bean时和从会话bean读取时是相同的@IlyaOvesnov源代码added@SotiriosDelimanolis添加的源代码
