Spring 批处理 - 如何在不同模式上创建元数据表?

Spring Batch - How to create metadata tables on Different schema?

我希望在同一 MySQL 主机上创建 Spring Batch Metadata table,但使用不同的架构。 我想在 Test 架构上创建应用程序特定表,在 batchmetadata 架构上创建元数据表。

错误:

Spring 将默认在您提供的模式中创建元数据表 spring.datasource.url。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 datasource。您可以将 datasource 用于您的主要逻辑。

例如,在 application.properties 中添加以下属性:

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 configuration class 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);

批量自动创建 table 适用于已定义的主架构。在你的情况下是

@Bean(name="secondaryDS")
@Primary
@ConfigurationProperties(prefix="spring.datasource")

所以它在 TEST 架构下创建 tables。如果您想要另一个模式中的批处理 table,请您自己手动创建它或将其他模式作为主要模式,一旦创建了 table,您就可以更改它。

感谢 Sushil 的指导。我能够通过以下 link: 解决问题。

spring.jpa.hibernate.ddl-auto=create 已停止工作,不是因为您有两个 DataSources,而是因为您的应用程序正在创建自己的 LocalContainerEntityManagerFactoryBeans。这会禁用 LocalContainerEntityManagerFactoryBean 的自动配置,因此您现在必须自己配置它。

test 架构 - 想要用于应用程序特定用途。

batchmetadata 架构 - 想要用于 Spring 批处理元数据表

所以,只需配置下面的 bean 以及 @PrimaryDS@SecondaryDS

@Bean(name = "primaryEntityManagerFactory")
    public LocalContainerEntityManagerFactoryBean primaryEntityManagerFactory( EntityManagerFactoryBuilder builder) {
        Map<String, Object> properties = new HashMap<String, Object>();
        properties.put("hibernate.hbm2ddl.auto", "update");
        return builder
                .dataSource(getSeconadaryBatchDataSource())
                .packages("com.example.model")
                .persistenceUnit("default")
                .properties(properties)
                .build();
    }

给你!!
