原因:组织。冬眠HibernateeException:当“hibernate”时,对方言解析信息的访问不能为null。未设置方言

hikaricp spring-data-jpa spring-boot

为了解决这个问题,我在互联网上到处搜索,但没有找到解决方案。希望有人能帮忙。在我的spring boot应用程序中。我第一次使用hikari访问两个不同的数据源,但出现了上述错误。

提前谢谢。

我终于明白了。我的Datasource1和Datasource2类缺少配置。setJdbcUrl(url)

@Bean
    public DataSource DataSourceTwo(){
        HikariConfig config = new HikariConfig();
        config.setDriverClassName(driver);
        config.setJdbcUrl(url);
        config.setUsername(username);
        config.setPassword(password);
        config.setAutoCommit(true);
        return new HikariDataSource(config);
    }

在我的LocalContainerEntityManagerFactoryBean中,我也未能包含entityManagerFactoryBean。setDataSource(DataSourceTwo());

@Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactoryBeanTwo() {
        HibernateJpaVendorAdapter jpaVendorAdapter = new HibernateJpaVendorAdapter();

        LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
        entityManagerFactoryBean.setJpaVendorAdapter(jpaVendorAdapter);
        entityManagerFactoryBean.setDataSource(DataSourceTwo());
        entityManagerFactoryBean.setPackagesToScan("com.deanace.oauth2.entities");
        return entityManagerFactoryBean;
    }
