如何使用弹簧数据-jpa使用存储库populator？

我正在使用Spring Data JPA，并试图使用存储库填充器来填充数据 - 但我得到了格式错误的json的异常。如何使用弹簧数据-jpa使用存储库populator？

我认为它可能是data.json文件的位置。我把，在META-INF文件夹和我配置测试用例如下

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(locations={"classpath:META-INF/integration-test-context.xml","classpath:META-INF/sample-data.xml"}) 
public class JpaCompanyRepositoryIntegrationTest{ 

//Test cases here 

}

我的样品data.xml中是：

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:repository="http://www.springframework.org/schema/data/repository" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans.xsd 
    http://www.springframework.org/schema/data/repository 
    http://www.springframework.org/schema/data/repository/spring-repository.xsd"> 

    <repository:jackson-populator location="classpath:data.json" /> 

</beans>

和data.json包含

[{"_class" : "com.some.Class", 
    "id" : "id1", 
    "firstname" : "Admin", 
    "lastname" : "admin" 
}, 
{ 
    "_class" : "com.some.Class", 
    "id" : "id2", 
    "firstname" : "user", 
    "lastname" : "user" 
}]

我得到以下异常：

所以我做了更多的调试，结果发现配置正在寻找repository populator定义中的“locations”属性 - 而xml需要“location”属性。我使用弹簧数据1.4.0.RELEASE和杰克逊1.9.2。我混合了依赖关系吗？
