尝试使用 JNDI 配置 2 个数据源，但出现错误。有 2 个包：
1-对于第一个数据源的实体和存储库。
2- 用于第二个数据源的实体和存储库。
我用于配置其中之一的代码：
@Configuration
@PropertySource(value = "classpath:application-prod.properties")
@EnableJpaRepositories(
basePackages = "com.example.test.repository",
entityManagerFactoryRef = "applicationEntityManagerFactoryBean",
transactionManagerRef = "applicationTransactionManager"
)
public class ApplicationDataSourceConfiguration {
@Value("${spring.datasource.outage.jndi-name}")
private String applicationJndiDatasourceName;
private HibernateProperties hibernateProperties;
@Autowired
public ApplicationDataSourceConfiguration(HibernateProperties hibernateProperties) {
this.hibernateProperties = hibernateProperties;
}
@Bean
@Primary
public DataSource applicationDataSource(){
JndiDataSourceLookup jndiDataSourceLookup = new JndiDataSourceLookup();
return jndiDataSourceLookup.getDataSource(applicationJndiDatasourceName);
}
@Bean
@Primary
public PlatformTransactionManager applicationTransactionManager(){
JpaTransactionManager jpaTransactionManager = new JpaTransactionManager();
jpaTransactionManager.setEntityManagerFactory(applicationEntityManagerFactoryBean().getObject());
return jpaTransactionManager;
}
@Bean
@Primary
public LocalContainerEntityManagerFactoryBean applicationEntityManagerFactoryBean(){
LocalContainerEntityManagerFactoryBean factoryBean = new LocalContainerEntityManagerFactoryBean();
factoryBean.setDataSource(applicationDataSource());
factoryBean.setPackagesToScan("com.example.test.entity");
factoryBean.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
factoryBean.setJpaProperties(hibernateProperties.getHibernateProperties());
factoryBean.afterPropertiesSet();
return factoryBean;
}
}
我的 HibernateProperies 类：
@Component
public class HibernateProperties {
private Environment environment;
@Autowired
public HibernateProperties(Environment environment) {
this.environment = environment;
}
public Properties getHibernateProperties() {
Properties jpaProperties = new Properties();
jpaProperties.put("hibernate.hbm2ddl.auto", Objects.requireNonNull(environment.getProperty("spring.jpa.hibernate.ddl-auto")));
jpaProperties.put("hibernate.jdbc.lob.non_contextual_creation", Objects.requireNonNull(environment.getProperty("spring.jpa.properties.hibernate.dialect")));
jpaProperties.put("hibernate.dialect", Objects.requireNonNull(environment.getProperty("spring.jpa.properties.hibernate.dialect")));
return jpaProperties;
}
}
我的 application.properties：
spring.jpa.hibernate.ddl-auto = update
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.SybaseDialect
spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true
spring.datasource.outage.jndi-name=java:comp/env/jdbc/app
spring.datasource.testdb.jndi-name=java:comp/env/jdbc/prod
以及我的 web.xml 的一部分：
<resource-ref>
<res-ref-name>jdbc/app</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
<resource-ref>
<res-ref-name>jdbc/prod</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
这是我的堆栈跟踪：

我是否没有正确配置数据源？
