Question

我开始学习spring-data-neo4j

非常基本的测试用例我正在运行但无法成功。错误是：java.lang.IllegalStateException: Failed to load ApplicationContext

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'neo4jRelationshipBacking' defined in class path resource [org/springframework/data/neo4j/aspects/config/Neo4jAspectConfiguration.class]: Instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Factory method [public org.springframework.data.neo4j.aspects.support.relationship.Neo4jRelationshipBacking org.springframework.data.neo4j.aspects.config.Neo4jAspectConfiguration.neo4jRelationshipBacking() throws java.lang.Exception] threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'neo4jTemplate' defined in class path resource [org/springframework/data/neo4j/aspects/config/Neo4jAspectConfiguration.class]: Instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Factory method [public org.springframework.data.neo4j.support.Neo4jTemplate org.springframework.data.neo4j.config.Neo4jConfiguration.neo4jTemplate() throws java.lang.Exception] threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mappingInfrastructure' defined in class path resource [org/springframework/data/neo4j/aspects/config/Neo4jAspectConfiguration.class]: Instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Factory method [public org.springframework.data.neo4j.support.MappingInfrastructureFactoryBean org.springframework.data.neo4j.config.Neo4jConfiguration.mappingInfrastructure() throws java.lang.Exception] threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'neo4jTransactionManager' defined in class path resource [org/springframework/data/neo4j/aspects/config/Neo4jAspectConfiguration.class]: Instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Factory method [public org.springframework.transaction.PlatformTransactionManager org.springframework.data.neo4j.config.Neo4jConfiguration.neo4jTransactionManager()] threw exception; nested exception is java.lang.NoSuchMethodError: org.neo4j.kernel.impl.transaction.SpringTransactionManager.<init>(Lorg/neo4j/graphdb/GraphDatabaseService;)V

User.java pojo用@NodeEntity

注释

@NodeEntity
public class User {
    @GraphId
    private Long id;

    User(String name){
        this.name = name;
    }
    private String name;

    public Long getId() {
        return id;
    }

    public String getName() {
        return name;
    }

}

配置文件是：

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"

    <neo4j:config  storeDirectory="D:/data/db"/>
    <tx:annotation-driven mode="proxy"/>
    <context:component-scan base-package="com.neo4j.model"/>
</beans>

JUnit测试用例：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:/graph-test-context.xml"})
public class Neo4jUserTest {

    @Autowired
    Neo4jTemplate neo4jTemplate;
    @Test
    public void test() {
        User user = new User("test");
        neo4jTemplate.beginTx();
        neo4jTemplate.save(user);
    }
}

Answer 1

正如Peter所说，问题是你要包含一个不同于Spring期望的Neo4J库的不同版本。 NoSuchMethodError 表示客户端正在调用不存在的方法。如果你包含Spring正在使用的版本，那么就不会发生这种情况如果他们调用了一个不存在的方法，那么Spring会遇到编译错误。

你是如何建立项目的？如果它是一个maven项目，请提供更多细节，如POM。

更新 org.neo4j.kernel.impl.transaction.SpringTransactionManager 来自您的Neo4J安装，而不是您提供的罐子。你在运行什么版本的Neo4J？它需要匹配spring-data-neo4j所期望的版本。

Answer 2

您似乎使用的是旧的Neo4j版本。你能尝试相应的Neo4j版本吗，我认为1.8而不是1.7.2？
