Description:
Field companyResouces in com.loanguruhub.controller.CompanyController required a bean named 'entityManagerFactory' that could not be found.

Consider defining a bean named 'entityManagerFactory' in your configuration.
我被困在两者之间。我已经尝试了几件事。由于提供了entityManager的hibernate-JPA入门程序也已从pom.xml中删除了hibernate-core和hibernate-entity-manager。但是我得到了同样的错误。除此之外，我还创建了如下的自定义datasoruce。
@Configuration
public class DatabaseConfiguration {
@Bean
@ConfigurationProperties("spring.datasource")
public DataSourceProperties dataSourceProperties() {
return new DataSourceProperties();
}
@Bean
@ConfigurationProperties("spring.datasource")
public HikariDataSource dataSource(DataSourceProperties properties) {
return properties.initializeDataSourceBuilder().type(HikariDataSource.class)
.build();
}
}
并尝试做同样的事情。但是又遇到了同样的错误。任何帮助都是可观的。
======更新======= CompanyController代码。
@RestController
@RequestMapping(
path = "/company",
produces=MediaType.APPLICATION_JSON_VALUE,
consumes=MediaType.APPLICATION_JSON_VALUE)
public class CompanyController {
@Autowired
private CompanyResources companyResouces;
}
错误跟踪与JDBC-URL相关

答案 0 :(得分：0)
有几件事需要修复，然后才能工作。.
由于使用的是jpa春季数据，因此休眠是默认实现，因此无需显式定义休眠依赖项，因为这可能会产生冲突，因此请从pom中删除它：
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version> 5.2.1.Final</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>5.2.3.Final</version>
</dependency>
当您还要传递数据源用户名和密码时，请从url中删除传递的参数：因此从spring.datasource.url中删除用户名和密码，仅从spring.datasource.username和{ {1}}。
是spring.datasource.password的默认连接池，Spring data jpa将基于application .properties自动配置数据源，因此也要删除配置：因此请删除以下类：
