SpringBoot启动报：Caused by: java.lang.IllegalArgumentException: At least one JPA metamodel must be pres

使用spring boot对项目改造，启动报错：

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

估计是跟多个数据源有关，改为以下这样就能够了

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

缘由：可能在启动其余项目的时候，一些持久化的bean被加载了，致使这种状况
