java.lang.NoSuchMethodError: javax.persistence.spi.PersistenceUnitInfo.getValidationMode()

异常：
java.lang.NoSuchMethodError: javax.persistence.spi.PersistenceUnitInfo.getValidationMode()Ljavax/persistence/ValidationMode;

通过分析发现pom.xml中引入了的是 persistence-api 版本问题

<dependency>
      <groupId>javax.persistence</groupId>
      <artifactId>persistence-api</artifactId>
      <version>1.0.2</version>
</dependency>

这个错误的原因在于 JPA1 API中找不到此javax.persistence.spi.PersistenceUnitInfo.getValidationMode()方法，此方法自JPA2.0才有的，所以我们可以使用Hibernate提供的jpa替换JPA1,也可以用javaee-api 代替

<dependency>
  <groupId>org.hibernate.javax.persistence</groupId>
  <artifactId>hibernate-jpa-2.0-api</artifactId>
  <version>1.0.1.Final</version>
</dependency>
