我已按照以下链接https://dzone.com/articles/spring-boot-hibernate-multitenancy-implementation
在启动应用程序中实现了多租户为此我从@SpringBootApplication
中排除了DatasourceAutoconfiguration.class
@SpringBootApplication(
exclude = {DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class})
@EnableScheduling
@EnableJpaRepositories
@EnableAspectJAutoProxy(proxyTargetClass = true)
@ComponentScan("com.mps")
public class MpsServiceClientApplication {
问题是,如何将spring.datasource.tomcat.*
之类的属性注入自定义数据源?更准确地说,如何将下面提到的2个属性设置为自定义数据源。
spring.datasource.test-while-idle=true
spring.datasource.test-on-borrow=true
这就是我设置jpa属性的方法。
final Map<String, Object> hibernateProps = new LinkedHashMap<>();
hibernateProps.putAll(this.jpaProperties.getProperties());
final LocalContainerEntityManagerFactoryBean result =
new LocalContainerEntityManagerFactoryBean();
result.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
result.setJpaPropertyMap(hibernateProps);
答案 0 :(得分:1)
您必须将这些属性注入@Configuration
bean并在手动创建Tomcat数据源时进行设置:
import org.apache.tomcat.jdbc.pool.DataSource;
@Value("${spring.datasource.test-on-borrow}")
private boolean testWhileIdle;
@Value("${spring.datasource.test-while-idle}")
private boolean testOnBorrow;
@Bean
public DataSource dataSource(){
DataSource dataSource = new DataSource();
dataSource.setTestOnBorrow(testOnBorrow);
dataSource.setTestWhileIdle(testWhileIdle);
...
return dataSource;
}
