我正在使用Spring和Neo4j lib 来制作REST Web 应用程序，它将操作 Neo4j 数据库上的数据。我正在努力配置我的项目，我无法在 Tomcat 中启动它。

我的HelloController课程在包中：com.testing.demo.neo

@Controller
@RequestMapping("/")
public class HelloController {

    @Autowired
    ItemRepository itemRep;

    @RequestMapping(value = "/user/{id}", method = RequestMethod.GET)
    public String getUser(@RequestParam int id) {
        User user = userRep.findByPropertyValue("id", id);
        if(user == null)
            return("User is null");
        else
            return user.toString();
    }

    @RequestMapping(value = "/user", method = RequestMethod.POST)
    public String addUser(@RequestBody User user) {
        userRep.save(user);
        return user.toString();
    }
    ...
}

我的UserRepository课程在包中：com.testing.demo.neo.repository

public interface UserRepository extends GraphRepository<User> {
}

我的调度-servlet.xml：

<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:neo4j="http://www.springframework.org/schema/data/neo4j"

    <tx:annotation-driven />

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/pages/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

    <!-- REST Connection to Neo4j server -->
    <bean id="restGraphDatabase"  class="org.springframework.data.neo4j.rest.SpringRestGraphDatabase">
        <constructor-arg value="http://localhost:7474/db/data/" />
    </bean>

    <!-- Neo4j configuration (creates Neo4jTemplate) -->
    <neo4j:config graphDatabaseService="restGraphDatabase" />
</beans>

我的 pom.xml 文件包括：

尝试在 Tomcat 上部署并运行应用程序时，出现以下错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'helloController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: com.testing.demo.neo.repository.UserRepository com.testing.demo.neo.HelloController.userRep; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'itemRepository': Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: Ljavax/validation/Validator;

我过去几天一直在寻找解决方案，但一直没有找到。如果您可以帮助我进行此配置，请。提前致谢。

编辑： 我通过更改spring.versionto3.1.0.RELEASE并添加以下依赖项来解决问题，pom.xml因为Hibernate ValidatorNeo4j 使用了以下依赖项：

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>4.2.0.Final</version>
</dependency>

您缺少以下依赖项

<dependency>
  <groupId>javax.validation</groupId>
  <artifactId>validation-api</artifactId>
  <version>1.1.0.Final</version>
</dependency>
