java - 在 Spring Boot 2 中使用实体管理器时，没有类型 'javax.persistence.EntityManager' 的合格 bean

转载作者：行者123 更新时间：2023-12-02 01:39:06

我正在将代码从 Spring Boot 1.5.4 迁移到 2.0.8。这样做时，实体管理器在 jboss 上部署时会抛出错误:

当对EntityManager使用@Autowired时:

No qualifying bean of type 'javax.persistence.EntityManager'

当使用@PersistenceContext时:

No qualifying bean of type 'javax.persistence.EntityManagerFactory'

我观察到，当我使用 infinispan 嵌入的 uber jar 时，这个问题不会出现在 jboss 上。我不想使用 uber jar，因为它会带来其他问题。

我正在将 @Autowired 的完整日志粘贴到 EntityManager 上。

注意:注释掉了 infinispan 的 uber jar(infinispan-embedded)，它解决了这个问题。但会导致其他重大问题。

更新3最终解决方案在已接受答案的聊天日志中提到。

最佳答案

由于您使用的是starter模块，因此不需要显式导入其他依赖项。
因此删除:

infinispan-spring4-embedded

我发现您正在明确导入 Spring Security。为什么不仅使用starter模块？

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>

删除

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-core</artifactId>
    <version>4.2.7.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-config</artifactId>
    <version>4.2.4.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-web</artifactId>
    <version>4.2.7.RELEASE</version>
</dependency>

<小时/>

关于Infinispan JCache ，我发现Spring已经支持JSR-107缓存注释 ( blog post )。

我认为根本不需要 CDI。因此，请同时删除

<dependency>
    <groupId>org.infinispan</groupId>
    <artifactId>infinispan-jcache</artifactId>
</dependency>
<dependency>
    <groupId>org.infinispan</groupId>
    <artifactId>infinispan-cdi-embedded</artifactId>
     <version>9.4.6.Final</version>
</dependency>

您还可以删除显式 Hibernate 导入

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>5.2.17.Final</version>
    <scope>provided</scope>
</dependency>
