Question

所以，我已经尝试了很多天来运行我的项目，但没有成功。 Spring Boot + Hibernate + JPA。 Oracle数据库。有人能帮助我吗？

config.properties：

spring.datasource.url=jdbc:oracle:thin:@localhost:1521:orcl
spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
spring.datasource.username=data_integration
spring.datasource.password=secret

堆栈跟踪：

Select count(*) from (

SELECT count(STATUS) AS STATUS, USER_ID from Table1 WHERE USER_ID = '65' group by STATUS, USER_ID
) as t

Answer 1

NoJtaPlatform表示您尚未设置hibernate.transaction.jta.platform。

JTA平台的未配置形式。如果未设置，则使用此方法。

在Spring Boot中，应该由HibernateJpaConfiguration进行设置。如果您自己配置LocalContainerEntityManagerFactoryBean，则需要手动进行。

我不确定为什么要定义自己的JPA Bean（或覆盖所有pom依赖项）。如果您全部删除了它们，那么它将开始工作。

@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

spring:
  datasource:
    url: 'jdbc:oracle:thin:@localhost:1521:orcl'
    username: data_integration
    password: secret
  jpa.hibernate.ddl-auto: validate
  mvc.view:
    prefix: /WEB-INF/pages/
    suffix: .jsp

此配置的唯一区别是静态路径是/static/**，而不是/static_content/**，但我认为没有理由不切换到默认路径。

如果您实际上想使用JTA（尽管您只有一个数据源而没有JMS，所以我不明白为什么），那么您将需要一个独立的提供程序，因为Tomcat没有。添加spring-boot-starter-jta-atomikos或spring-boot-starter-jta-bitronix。

DdlTransactionIsolatorJtaImpl无法找到TransactionManager
