我希望在相同的MySQL
主机上创建Spring批处理元数据表
,但使用不同的模式。我想在测试模式上创建特定于应用程序的表,在batchmetadata模式上创建元数据表。

默认情况下,Spring将在您在Spring.datasource.url
中提供的模式中创建元数据表。您需要在spring.datasource.*
属性中配置BatchMetadata
。您可以使用其他自定义属性来创建单独的数据源
。您可以将DataSource
用于主逻辑。
例如,在应用程序中添加以下属性。properties
:
spring.datasource.test.url=jdbc:mysql://localhost/test
spring.datasource.test.username=root
spring.datasource.test.password=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
在您的配置
类中创建DataSource
,如下所示:
@Value("${spring.datasource.driver-class-name}")
private String driverClass;
@Value("${spring.datasource.test.url}")
private String url;
@Value("${spring.datasource.test.username}")
private String userName;
@Value("${spring.datasource.test.password}")
private String pass;
HikariConfig config = new HikariConfig();
config.setDriverClassName(driverClass);
config.setJdbcUrl(url);
config.setMaximumPoolSize(5);
config.setUsername(userName);
config.setPassword(pass);
config.setConnectionTestQuery("select 1 from dual");
DataSource test = new HikariDataSource(config);
假设我有一个表'some-table',我想在多个模式中创建它。名为“create-some-table.yaml”的文件 最后一个是changelog-master,它非常简单 有什么办法我可以做类似这样的事情吗,谢谢:)
我的应用程序中有一个连接到Oracle数据库的数据源。是否可以通过此数据源访问另一个包含Spring批处理元数据表的模式?此数据源的用户拥有访问其他架构的所有权限。 我已经尝试过JobRepository的“tablePrefix”属性,例如“Schema.batch\u0”。但它不起作用。简单地说,我搜索告诉Spring批处理访问元数据表的方法,如“select….from Schema.bat
我试图为一个包含不同类型对象数组的对象定义一个swagger模式定义。 下面是模板对象(以及所有相关对象类型)的 json 架构。我知道 swagger 不支持 oneOf 谓词,所以我只是想弄清楚如何在 swagger 中描述这个数据结构。我已经尝试了这种语法的许多变体,但没有一个有效,这是我根据规范和这里找到的一些例子所能达到的最接近的:http://json-schema.org/examp
问题内容: 我需要将一些参数传递给服务器,我需要按照以下格式传递 那么如何在Android中生成这种格式。 我尝试使用如示例5.3中所示的方法,但此行显示错误。任何人都可以帮助解决这个问题。 提前致谢 问题答案: 并不是全部,您想要的输出是JSONObject内的JSONArray和另一个JSONObject内的JSONObject。因此,您可以单独创建它们,然后将它们放在一起。如下。 输出-
问题内容: 我有一个使用在不同地理位置的四个数据库的应用程序。所有数据库都包含相同的表,只有数据库名称根据位置而不同。我必须在应用程序中创建一些报告,这些报告使用每个数据库中的数据。从Java应用程序创建那些数据库连接的正确方法是什么,是否有适合我使用的适合此任务的设计模式? 问题答案: 由于您没有任何的标记这个你的问题,,,,我假设你正在处理普通的JDBC。 话虽如此,我建议您有一个DAO层来处
