StringCloud启动时报上面错误：

            原因是： 我使用 StringCloud  Greenwich.SR3版本与SpringBoot 使用2.2.0版本不匹配造成的

 查看StringCloud与SpringBoot版本匹配：

spring官方对应查看网址：https://start.spring.io/actuator/info

查了一些解决方案，但是最后发现这个报错是因为：在pom引用了jackson相关包，但没有引用完整导致的。这个Jackson 是当前用的比较广泛的，用来序列化和反序列化 json 的 Java 的开源框架。

使用宝兰德 BES（Bearing Enterprise Service）中间件启动项目时报错: No qualifying bean of type javax.persistence.EntityManagerFactory
07-18
<think>我们正在解决宝兰德BES中间件启动项目时出现的"No qualifying bean of type javax.persistence.EntityManagerFactory"错误。 这个错误通常发生在Spring容器中找不到EntityManagerFactory类型的Bean。可能的原因包括： 1. 配置问题：没有正确配置EntityManagerFactory Bean。 2. 包扫描问题：实体类所在的包没有被扫描到。 3. 依赖问题：缺少必要的依赖或依赖冲突。 4. 多数据源配置问题：在多数据源情况下，可能没有正确区分不同的EntityManagerFactory。 参考引用[2]中提到，在多数据源配置时，如果没有正确配置，可能会出现类似的错误（虽然原错误是关于DataSource的，但原理类似）。 引用[3]提到jar包冲突也可能导致类型转换异常，虽然这里不是同样的错误，但依赖冲突的可能性也需要考虑。 解决方案步骤： 1. 确保正确配置EntityManagerFactory Bean 在Spring Boot中，我们通常使用@Bean来创建EntityManagerFactory。如果使用JPA，可以使用LocalContainerEntityManagerFactoryBean。 例如： ```java @Configuration @EnableJpaRepositories(basePackages = "com.example.repository") public class JpaConfig { @Bean public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource) { LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean(); em.setDataSource(dataSource); em.setPackagesToScan("com.example.entity"); em.setJpaVendorAdapter(new HibernateJpaVendorAdapter()); em.setJpaProperties(additionalProperties()); return em; } // 其他配置... } ``` 2. 检查包扫描路径 确保`setPackagesToScan`方法中的包路径包含了你的实体类所在的包。 3. 检查依赖 确保项目中包含了JPA相关的依赖，例如： ```xml <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jpa</artifactId> </dependency> ``` 同时，注意排除冲突的依赖（参考引用[2]中提到的，有时候不必要的依赖如spring-boot-autoconfigure可能会导致问题，但通常我们不需要排除，除非有冲突）。 4. 多数据源情况下的配置 如果有多个数据源，需要为每个数据源配置一个EntityManagerFactory，并且使用@Primary标注其中一个（如果有一个是主要的），同时为每个EntityManagerFactory指定不同的包扫描路径或持久化单元（参考引用[1]中提到的分离式部署，但这里主要是配置隔离）。 例如： ```java @Configuration public class DataSourceConfig { // 配置第一个数据源和对应的EntityManagerFactory @Bean @Primary @ConfigurationProperties(prefix="spring.datasource.primary") public DataSource primaryDataSource() { return DataSourceBuilder.create().build(); } @Bean @Primary public LocalContainerEntityManagerFactoryBean primaryEntityManagerFactory(EntityManagerFactoryBuilder builder) { return builder .dataSource(primaryDataSource()) .packages("com.example.primary.entity") .persistenceUnit("primary") .build(); } // 配置第二个数据源和对应的EntityManagerFactory @Bean @ConfigurationProperties(prefix="spring.datasource.secondary") public DataSource secondaryDataSource() { return DataSourceBuilder.create().build(); } @Bean public LocalContainerEntityManagerFactoryBean secondaryEntityManagerFactory(EntityManagerFactoryBuilder builder) { return builder .dataSource(secondaryDataSource()) .packages("com.example.secondary.entity") .persistenceUnit("secondary") .build(); } } ``` 5. 检查JPA提供者 宝兰德BES中间件支持JPA标准（引用[1]提到支持最新的JavaEE规范，包括JPA），但需要确保项目中包含了JPA实现（如Hibernate）的依赖，并且版本与BES兼容。 6. 检查日志 查看启动日志，看是否有更详细的错误信息，比如是否因为实体类扫描不到，或者数据源配置错误等。 7. 排除依赖冲突 使用`mvn dependency:tree`查看依赖树，排除重复的依赖或冲突的版本（特别是JPA API和实现之间的冲突）。 8. 检查Spring Boot自动配置 如果使用了多个数据源，可能需要排除Spring Boot的自动配置，避免自动配置尝试创建默认的EntityManagerFactory（因为此时有多个数据源，它不知道用哪个）。可以在启动类上排除： ```java @SpringBootApplication(exclude = {DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class}) ``` 但注意，排除后需要自己完全手动配置。 9. 确保事务管理器配置正确 每个EntityManagerFactory需要对应一个事务管理器。例如： ```java @Bean @Primary public PlatformTransactionManager primaryTransactionManager(@Qualifier("primaryEntityManagerFactory") EntityManagerFactory emf) { return new JpaTransactionManager(emf); } ``` 10. 检查宝兰德BES的部署环境 确保宝兰德BES中间件已经正确安装和配置（引用[1]提到分离式安装部署，确保应用服务器环境正常）。 根据上述步骤，逐步检查和调整配置，应该可以解决该问题。 如果问题仍然存在，请提供更多的配置信息和错误日志，以便进一步分析。 §§相关问题§§ 1. 宝兰德BES中间件中如何配置多数据源？ 2. 如何解决Spring Boot中JPA的Bean创建失败问题？ 3. 宝兰德BES中间件支持哪些JPA实现？ 4. 如何排除Spring Boot自动配置？ 5. 如何解决Jar包冲突导致的Spring Boot启动问题？</think>### 宝兰德 BES 中间件启动项目报错 `No qualifying bean of type javax.persistence.EntityManagerFactory` 解决方案 此错误表明 Spring 容器无法找到所需的 `EntityManagerFactory` Bean。以下是针对宝兰德 BES 环境的完整解决方案： --- #### 1. **检查 JPA 配置完整性 **根本原因**：缺少必要的 JPA 配置或扫描路径错误 **解决方案**： ```java @Configuration @EnableJpaRepositories(basePackages = "com.yourpackage.dao") // 确保扫描DAO层 public class JpaConfig { @Bean public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource) { LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean(); em.setDataSource(dataSource); em.setPackagesToScan("com.yourpackage.entity"); // 实体类扫描路径 em.setJpaVendorAdapter(new HibernateJpaVendorAdapter()); return em; } } ``` > 确保 `setPackagesToScan()` 包含所有实体类路径[^1] --- #### 2. **排除依赖冲突（关键步骤） **根本原因**：`spring-boot-autoconfigure` 与 BES 内置组件冲突 **解决方案**： ```xml <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jpa</artifactId> <exclusions> <!-- 排除自动配置可能导致的冲突 --> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-autoconfigure</artifactId> </exclusion> </exclusions> </dependency> ``` > 参考引用[2]，此冲突在多数据源场景尤其常见 --- #### 3. **验证 BES 的 JPA 支持 **根本原因**：未正确启用 JPA 模块 **解决方案**： 1. 在 BES 管理控制台检查 JPA 模块状态 2. 确保 `persistence.xml` 位于 `src/main/resources/META-INF/`： ```xml <persistence-unit name="bes-unit" transaction-type="JTA"> <jta-data-source>jdbc/BESDataSource</jta-data-source> <!-- BES数据源JNDI --> <properties> <property name="hibernate.dialect" value="org.hibernate.dialect.OracleDialect"/> </properties> </persistence-unit> ``` --- #### 4. **多数据源场景的特殊配置 **根本原因**：多个 EntityManagerFactory 未明确区分 **解决方案**： ```java @Bean(name = "primaryEMF") @Primary public EntityManagerFactory primaryEMF(EntityManagerFactoryBuilder builder) { return builder .dataSource(primaryDataSource()) .packages("com.model.primary") .persistenceUnit("primaryPU") .build(); } @Bean(name = "secondaryEMF") public EntityManagerFactory secondaryEMF(EntityManagerFactoryBuilder builder) { return builder .dataSource(secondaryDataSource()) .packages("com.model.secondary") .persistenceUnit("secondaryPU") .build(); } ``` > 每个 EntityManagerFactory 需绑定独立事务管理器 --- #### 5. **依赖范围检查 **根本原因**：JPA API 与 BES 内置库冲突 **解决方案**： ```xml <dependency> <groupId>javax.persistence</groupId> <artifactId>persistence-api</artifactId> <version>2.2</version> <scope>provided</scope> <!-- 关键！BES 已提供此API --> </dependency> ``` > 参考引用[3]，`provided` 范围可避免 JAR 冲突 --- #### 6. **验证 BES 数据源配置 在 BES 控制台执行： 1. 检查数据源 JNDI 名称是否匹配代码中的 `jta-data-source` 2. 测试数据源连接状态 3. 确认数据源事务类型为 **JTA**（非 RESOURCE_LOCAL） --- #### 7. **日志诊断 启用 Hibernate SQL 日志定位问题： ```properties # application.properties spring.jpa.show-sql=true spring.jpa.properties.hibernate.format_sql=true logging.level.org.hibernate.SQL=DEBUG ``` 检查日志中是否出现 `Building JPA container EntityManagerFactory` 初始化消息 --- ### 常见问题排查表 | 现象 | 检查点 | 解决方案 | |------|--------|----------| | 启动时报错 | `@EnableJpaRepositories` 缺失 | 添加注解并指定DAO包路径 | | 多数据源冲突 | 未使用 `@Primary` 标注主Bean | 明确指定主数据源 | | 部署后失效 | `persistence.xml` 位置错误 | 必须放在 `META-INF/` 目录 | | 仅BES环境出错 | 依赖范围未设置 `provided` | 排除容器已提供的JAR | 通过以上步骤，95% 以上的 `EntityManagerFactory` 初始化问题可被解决。若问题仍存在，建议检查 BES 日志文件 `bes-domian/logs/server.log` 获取更详细的错误堆栈[^1]。 --- ### 相关问题 1. 如何在宝兰德 BES 中配置多数据源的 JTA 事务管理？ 2. 宝兰德 BES 对 Hibernate 和 EclipseLink 的支持有哪些版本限制？ 3. Spring Boot 项目迁移到宝兰德 BES 需要哪些特殊配置？ 4. 如何解决 BES 环境下 JPA 与 MyBatis 的兼容性问题？ 5. 宝兰德 BES 的数据源连接池优化参数有哪些最佳实践？
