SpringBoot啟動報：Caused by: java.lang.IllegalArgumentException: At least one JPA metamodel must be present!

使用spring boot對項目改造，啟動報錯：

Caused by: java.lang.IllegalArgumentException: At least one JPA metamodel must be present!

估計是跟多個數據源有關，改成如下這樣就可以了

    @SpringBootApplication    
    @EnableAutoConfiguration(exclude={    
          JpaRepositoriesAutoConfiguration.class//禁止springboot自動加載持久化bean  
            })    
    @ImportResource({"classpath:spring-servlet.xml"})    
    public class JzApplication {    
            
        public static void main(String[] args) throws Exception {    
            ApplicationContext ctx = SpringApplication.run(JzApplication .class,args);    
        }    
    }   

原因：可能在啟動其他項目的時候，一些持久化的bean被加載了，導致這種情況
