Bean验证无法使用spring数据neo4j

Question

我正在使用SDN和嵌入式neo4j。我必须使用bean验证，但它不起作用。null正在数据库中保存，没有任何异常。

依赖是

dependencies {
    // specify dependencies here under either 'build', 'compile', 'runtime', 'test' or 'provided' scopes e.g.
    // runtime 'mysql:mysql-connector-java:5.1.29'
    // runtime 'org.postgresql:postgresql:9.3-1101-jdbc41'
    test "org.grails:grails-datastore-test-support:1.0-grails-2.4"
    compile 'org.springframework.data:spring-data-neo4j:3.2.0.RELEASE'
    compile 'org.hibernate:hibernate-validator:4.3.1.Final'
    compile 'javax.validation:validation-api:1.0.0.GA'      
}

xml config is 

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:neo4j="http://www.springframework.org/schema/data/neo4j"
xsi:schemaLocation="

<neo4j:config

base-package="neo4j"/>

<bean id="validator"
class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean"/>

<neo4j:repositories base-package="neo4j" />
</beans>

实体类

@NodeEntity
class Role {
    @GraphId Long graphId

    @NotNull
    String name;

}

控制器是

@Transactional
    def saveUser(){

        println "in saveUser"
        Role role = new Role();
        Neo4jTemplate.save(role);

    }

我使用的是sping-data-neo4j 3.2.0。发布
