I know this question is already posted by someone but that does not solved my problem I'm still getting the following error ,could you please let me know what is wrong with this

我知道有人已经发布了这个问题,但这并没有解决我的问题我仍然收到以下错误,你能告诉我这有什么问题吗

Description:

Field shopRepository in com.test.assertmanagementdigital4.service.ShopService required a bean named 'entityManagerFactory' that could not be found.


Action:

Consider defining a bean named 'entityManagerFactory' in your configuration.

If I remove exclude auto configuration, I got following error

如果我删除排除自动配置,则会出现以下错误

If you dismiss auto configuration, then you should provide it by yourself.

如果您关闭自动配置,那么您应该自己提供它。

See example:

见示例:

@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() throws URISyntaxException {
    LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
    entityManagerFactoryBean.setDataSource(your_datasource);
    entityManagerFactoryBean.setPackagesToScan(package_to_scan);
    //additional config of factory

    return entityManagerFactoryBean;
}

@Bean(name = "transactionManager")
public PlatformTransactionManager jpaTransactionManager(EntityManagerFactory entityManagerFactory) throws URISyntaxException {
    JpaTransactionManager transactionManager = new JpaTransactionManager();
    transactionManager.setEntityManagerFactory(entityManagerFactory);
    return transactionManager;
}

If you have this piece of code, just remove it.

如果您有这段代码,只需将其删除即可。

public HibernateJpaSessionFactoryBean sessionFactory() {
    return new HibernateJpaSessionFactoryBean();
}

This problem is due to tomcat connection pooling. Try to add following dependency in your pom.xml

这个问题是由于 tomcat 连接池造成的。尝试在 pom.xml 中添加以下依赖项

    <dependency>
        <groupId>org.apache.tomcat</groupId>
        <artifactId>tomcat-jdbc</artifactId>
    </dependency>

It solved my problem.

它解决了我的问题。
