Java 自动连线失败：不是托管类型

我的毕业设计有个大问题，如果你们能帮助我，我会非常高兴的！ 我做了一个Maven多模块项目，有3个“核心项目”

• NaviClean

  ：（父级）

• NaviCleanDomain

  ：包含域模型以及所有我的实体和 NaviCleanServer所需的接口

  MeinRemoteDienst

  和

  NaviCleanCleint

  用于

  Hessianprotocol

• NaviCleanClient

  ：连接GUI和到的Hessian连接

  NaviCleanServer

• NaviCleanServer

  ：这是我的存储库，我与数据库的连接 以及接口的实现

  einRemoteDienst

  NaviCleanServer

  和

  NaviCleanClient

  在Maven as中具有

  NaviCleanDomain

  依赖性

现在，每次我尝试在Tomcat上启动服务器时，都会出现以下错误：

2。我在persistence.xml中手动插入域模型存储库。结果是“绿色”测试，但我仍然无法启动服务器…

提前多谢！！！我无法想象没有您会是什么样子：）

您应该扩展组件扫描的范围，例如

，因为您将实体放在package

at.naviclean.domain中

这将有助于您摆脱例外：
不是托管类型：类位于.naviclean.domain.Kassa

为了进一步调试，您可以尝试转储应用程序上下文（请参阅javadoc），以探索组件扫描检测到的类（如果某些类仍然无法识别），请检查它们的注释（@Service、@component等）

编辑：

您还需要将类添加到
persistence.xml

<persistence-unit>
    <class>at.naviclean.domain.Kassa</class>
     ...
</persistence-unit>


at.naviclean.domain.Kassa

您得到的最后一个异常实际上表明您的JPA有问题
设置。“非托管bean”表示JPA提供者不知道的类型
属于如果您正在设置一个基于Spring的JPA应用程序，我推荐您
要在上配置“packagesToScan”属性，请执行以下操作：
已配置到包的LocalContainerEntityManagerFactory
它包含您的JPA实体。或者，您可以列出您的所有
persistence.xml中的实体类，但这通常更麻烦

您得到的前一个错误（NoClassDefFound）指示该类
在projects类路径上不可用。所以你可能
要检查您的模块间依赖关系。作为两个
相关类似乎也位于同一个模块中
只是Tomcat部署不完整的问题（WTP是一种
有时指恶毒的）。我绝对建议你为我的孩子做个测试
验证（正如您已经做的那样）。因为这似乎会把你带到一个
不同的例外，我想这真的是Eclipse的一些小故障

谢谢
 参考奥利弗·吉尔克的提示：

当persistence.xml的操作成功时，您就创建了一个普通的java类而不是实体类

创建新实体类时，persistence.xml中的条目应该由Netbeans设置（在我的例子中）

但是正如Oliver Gierke所提到的，您可以稍后将条目添加到persistence.xml（如果您创建了一个普通的java类）。
在我的例子中，当使用IntelliJ时，我在项目中有多个模块。主模块依赖于另一个模块，该模块对Spring具有maven依赖性

主模块有
实体
s，第二个模块也有。但是当我运行主模块时，只有来自第二个模块的
实体
被识别为托管类

然后我又在主模块上添加了Spring依赖项，猜猜看是什么？它识别了所有的
实体。
在spring boot中，我使用Crudepository得到了相同的异常，因为我忘记设置泛型类型。我想把它写在这里，以防对某人有所帮助

错误定义：

public interface OctopusPropertiesRepository extends CrudRepository

public interface OctopusPropertiesRepository extends CrudRepository<OctopusProperties,Long>{

错误：

Caused by: java.lang.IllegalArgumentException: Not a managed type: class java.lang.Object

成功定义：

public interface OctopusPropertiesRepository extends CrudRepository

public interface OctopusPropertiesRepository extends CrudRepository<OctopusProperties,Long>{

公共接口OctopusPropertiesRepository扩展了Crudepository{
您需要检查软件包扫描

<bean id="entityManagerFactoryDB" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
    <property name="dataSource" ref="dataSourceDB" />
    <property name="persistenceUnitName" value="persistenceUnitDB" />
    <property name="packagesToScan" value="at.naviclean.domain" />
                                            //here
 .....

当您间接扩展JpaRepository（KassaRepository扩展了扩展JpaRepository的BaseRepository）时，您必须使用
@NoRepositoryBean
注释BaseRepository：

@NoRepositoryBean
public interface BaseRepository<T extends ModelBase> extends JpaRepository<T, Long> {
    T findById(long id);
}

@NoRepositoryBean
公共接口BaseRepository扩展了JpaRepository{
T findById（长id）；
}
根据@alfred_m的说法，对我来说，这个错误非常简单……tomcat有两个JAR，它们具有相同的类名和配置集

所发生的事情是…………我复制了我的现有项目，以便在现有项目的基础上创建一个新项目。但没有进行必要的更改，我开始处理其他项目。Henec 2项目具有相同的类和配置文件，导致冲突

删除了复制的项目并开始工作！！！！
如果有人遇到同样的问题，我通过在我的主类中添加
@EntityScan
解决了它。只需将模型包添加到basePackages属性。
遇到此问题并尝试了将实体PackageName添加到EntityScan的不同方法后，组件扫描等等，都不起作用

将包添加到存储库配置的EntityManagerFactory中的packageScan配置中。下面的代码给出了基于代码的配置，而不是上面回答的基于XML的配置

@Primary
@Bean(name = "entityManagerFactory")
public EntityManagerFactory entityManagerFactory() {
    LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean();
    emf.setDataSource(dataSource);
    emf.setJpaVendorAdapter(jpaVendorAdapter);
    emf.setPackagesToScan("org.package.entity");
    emf.setPersistenceUnitName("default"); 
    emf.afterPropertiesSet();
    return emf.getObject();
}

当您将不正确的实体对象传递给repository类中的Crudepository时，会出现相同的异常

public interface XYZRepository extends CrudRepository<IncorrectEntityClass, Long>

public interfa
