Java 使用jpa存储库时的Zks Servlet.service（）NPE

我现在有一个令人困惑的问题

我正在启动一个Spring Boot+ZK网络应用程序。到目前为止，我做了一个安全登录，根据登录用户的角色重定向到不同的页面。这些数据存储在我的MySQL数据库中，我使用JPA访问该数据库。由于这一点和一些早期的测试，我知道我的配置在ZK、Spring和JPA之间工作正常

现在我尝试显示超级用户角色的用户列表。为此，我使用了名为query findAll（）的默认值，但这恰恰是我遇到问题的地方。如果我尝试在ViewModel类中使用我的repo，我会在使用所述repo的行中得到一个NullPointerException。查询本身没有被调用，它在创建回购协议时会停止

通过阅读大量其他案例，我得出结论，我的配置是正常的（加上我已经有了我的repo用于登录），因此必须有另一个问题，这将我指向DHtmlLayoutServlet。STS抛出2个错误堆栈：

我从中猜到的是，问题在于ZKs Servlet。。。但为什么它在使用独立组件的同时这么做呢？当我还没有使用数据时，JPA接口怎么会抛出这个异常呢？我很困惑。到目前为止，我已经尝试了不同的配置，它们应该做相同的事情，尝试了不同的设置，比如@wirel变量、@Resource和@Autowired，我的自定义LoginsAccessHandler和我的SuperUserPanelVM（Resource和Autowired工作正常。wirel变量没有，但我不希望它能工作）并检查是否存在非托管依赖项

数据库中有数据。我正在查询Users/Usuarios，它有2条记录。此表中没有可为空的值。即使有一个空的结果集，因为我没有用它做任何事情，它也不会停止，所以至少我知道它不喜欢我尝试使用回购

这是我的（相关部分）代码：

SuperUserPanel.java

公共类SuperUserPanelVM{
//（@wirelaviable/@Resource/@Autowired）->任何一个都不起作用，没有注释也不起作用
私人用益储蓄用益储蓄；
@初始化
公共void init（）{
通常是positionary.findAll（）；//->它在这里爆炸
}
}

UsuariosRepository.java

@存储库
公共接口常用存储扩展了JPA存储{
Usuarios findByCorreo（String correo）；//用于登录
}

Usuarios.java

@实体
@表（name=“usuarios”）
@NamedQuery（name=“Usuarios.findAll”，query=“从Usuarios u中选择u”）
公共类用益{
@身份证
@GeneratedValue（策略=GenerationType.IDENTITY）
@列（name=“id\u usuario”）
私家侦探；
@列（name=“correo”）
私有字符串correo；
@列（name=“nombre”）
私有字符串名称；
@列（name=“apellido\u paterno”）
私有字符串apellidopterno；
@列（name=“apellido_materno”）
私有字符串apellidoMaterno；
@列（name=“telefono”）
私人串电话；
@列（name=“password”）
private String password；//这将进一步提高安全性，dw
@列（name=“rol”）
私有字符串rol；
/*塞特和盖特*/
}

DatabaseAuthProvider.java（repo工作的地方）

@组件
公共类DatabaseAuthProvider实现AuthenticationProvider{
@资源
私人用益储蓄用益储蓄；
@凌驾
公共布尔支持（类身份验证）{
返回authentication.equals（UsernamePasswordAuthenticationToken.class）；
}
@凌驾
公共身份验证（Authentication auth）引发AuthenticationException{
//检查creds+重定向
}
}

我唯一引用DHtmlLayoutServlet的地方是在注册所述servlet时：

ProjectWebConfig.java

@配置
公共类ProjectWebConfig实现WebApplicationInitializer{
私有静态最终类[]配置类=新类[]{Config.Class，Security.Class}；
@凌驾
启动时公共void（ServletContext ServletContext）引发ServletException{
registerListener（servletContext）；
registerDispatcherServlet（servletContext）；
registerSpringSecurityFilterChain（servletContext）；
}
私有无效注册表列表器（ServletContext ServletContext）{
AnnotationConfigWebApplicationContext rootContext=createContext（配置类）；
addListener（新的ContextLoaderListener（rootContext））；
addListener（新的RequestContextListener（））；
addListener（新的HttpSessionListener（））；
}
私有无效注册表DispatcherServlet（ServletContext ServletContext）{
AnnotationConfigWebApplicationContext dispatcherContext=新的AnnotationConfigWebApplicationContext（）；
register（Config.class）；
ServletRegistration.Dynamic dispatcher=servletContext.addServlet（“zkLoader”，新的DHtmlLayoutServlet（））；
setInitParameter（“更新uri”，“/zkau”）；
dispatcher.setLoadOnStartup（1）；
dispatcher.addMapping（“*.zul”）；
dispatcher=servletContext.addServlet（“auEngine”，新的DHtmlUpdateServlet（））；
dispatcher.addMapping（“/zkau/*”）；
}
私有无效注册表SpringSecurityFilterChain（ServletContext ServletContext）{
//...
}
专用注释ConfigWebApplicationContext createContext（最终类…注释类）{
//...
}
}

我想我忽略了一些重要的事情，但我是那种在沮丧时会失去注意力的人。另一方面，ProjectWebConfig.java中的Config.class有@ComponentScan@

<window viewModel="@id('vm') @init('my.package.SuperUserPanelVM')" ...

@WireVariable
private UsuariosRepository usuariosRepository;

import org.zkoss.zkplus.spring.DelegatingVariableResolver

@VariableResolver(DelegatingVariableResolver.class)
public class SuperUserPanelVM {
  @WireVariable
  private UsuariosRepository usuariosRepository;

@Repository("usuariosRepository")
public interface UsuariosRepository extends JpaRepository<Usuarios, Integer>{
