Java 错误-NoSuchBeanDefinitionException:没有名为'；实体管理工厂&x27；可获得的

我正在尝试用SpringBatch和jpa开发一个新批次。当我尝试启动它时，我收到错误“嵌套异常为org.springframework.beans.factory.NoSuchBeanDefinitionException:没有名为“entityManagerFactory”的bean可用”

这里是我的pom.xml

有人可以帮我吗？

您正在调用的是方法

TestIDataSourceProperties

，而不是bean

试试这个：

@Bean
@Primary
@ConfigurationProperties("persistence.datasource.xid.hikari")
public DataSource testIdDataSource(@Autowired DataSourceProperties dataSourceProperties) {
    return dataSourceProperties.initializeDataSourceBuilder().build();
}

您使用的是哪个Hibernate ORM版本？这可能与Spring Boot版本不匹配。好的一点是，我更改了pom，删除了Spring Boot starter数据jpa中的排除项，并删除了依赖项org.eclipse.persistence org.eclipse.persistence.jpa。现在与数据源的连接起作用了……我有一个java.lang.IllegalArgumentException：方法public abstract java.util.List com.test.testid.batch.testidbebatch.dao.xid.repository.UserReportsLogpository.getReports（java.util.Date）的验证失败！但我认为这是另一个问题，请编辑您的问题以使其他人更易于阅读，尤其是样板实体方法。为什么要将hibernate从starter依赖项中排除？您使用的是哪个hibernate ORM版本？这可能与Spring Boot版本不匹配。好的一点是，我更改了pom，删除了Spring Boot starter数据jpa中的排除项，并删除了依赖项org.eclipse.persistence org.eclipse.persistence.jpa。现在与数据源的连接起作用了……我有一个java.lang.IllegalArgumentException：方法public abstract java.util.List com.test.testid.batch.testidbebatch.dao.xid.repository.UserReportsLogpository.getReports（java.util.Date）的验证失败！但我认为这是另一个问题，请编辑您的问题以使其他人更易于阅读，尤其是样板实体方法。为什么要将hibernate从starter依赖项中排除？嗨，我已经按照你说的做了尝试。我收到同样的错误嗨，我已经按你说的做了。我收到了同样的错误
