Spring data elasticsearch CRUD配置

Question

我在配置spring data elasticsearch时遇到了问题，我遵循了这里提到的Crud存储库spring bean配置的过程。但我得到了错误：

线程“main”org.springframework.beans.factory.beanCreationException中出现异常：创建名为“customer service”的bean时出错：注入资源依赖项失败；嵌套异常为org.springframework.beans.factory.BeanCreationException：创建名为“Customer Repo”的bean时出错：设置bean属性“elasticsearch operations”时无法解析对bean“elasticsearch template”的引用；嵌套异常为org.springframework.beans.factory.BeanCreationException：创建类路径资源[spring-repository.xml]中定义的名为'elasticsearch template'的bean时出错：bean实例化失败；嵌套异常为org.springframework.beans.beanInstantiationException：无法实例化bean类[org.springframework.data.elasticsearch.core.elasticsearchtemplate]:构造函数引发异常；嵌套异常为java.lang.NosuchMethodError：com.fasterxml.jackson.core.jsonFactory.RequiresPropertyRerding（）Z

代码如下：

CustomerService.java

@Service
public class CustomerService {
@Resource
CustomerRepo custRepo;

public void save(Customer cust) {
    custRepo.save(cust);
}
}

customer.java

@Document(
        indexName = "Customer", type = "cust"
        )
public class Customer {

@Id
private String id;
private String name;

public Customer(String name) {
    this.name = name;
}

public String getName() {
    return this.name;
}
public String getId() {
    return id;
}

public void setId(String id) {
    this.id = id;
}
}

public interface CustomerRepo  extends ElasticsearchRepository<Customer, String> {
}

public class MainClass {
public static void main(String args[]) {
    ApplicationContext context =
            new ClassPathXmlApplicationContext(new String[] {"spring-customer.xml"});
    CustomerService cust = (CustomerService)context.getBean("CustomerService");
    Customer customer = new Customer("test_name");
    cust.save(customer);
}
}

<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:context="http://www.springframework.org/schema/context"
   xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd  http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
<context:component-scan base-package="com.elasticsearch" />

<import resource="spring-repository.xml"/>

</beans>

spring-repository.xml

<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xmlns:elasticsearch="http://www.springframework.org/schema/data/elasticsearch"
   xsi:schemaLocation="http://www.springframework.org/schema/data/elasticsearch
   http://www.springframework.org/schema/data/elasticsearch/spring-elasticsearch.xsd
   http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.1.xsd">

<elasticsearch:transport-client id="client" cluster-nodes="xx.xx.xx.xx:9200" />

<bean name="elasticsearchTemplate"
      class="org.springframework.data.elasticsearch.core.ElasticsearchTemplate">
    <constructor-arg name="client" ref="client" />
</bean>

<elasticsearch:repositories
        base-package="com.elasticsearch.repositories" />

我不知道为什么它不起作用。请帮帮我。

修改了这些文件后，它终于起作用了：

1）spring-customer.xml

<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:context="http://www.springframework.org/schema/context"
   xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd  http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
<context:component-scan base-package="com.elasticsearch.repositories" />

<import resource="spring-repository.xml"/>
<bean id="customerService" class="com.elasticsearch.CustomerService" scope="prototype" >
        <property name="custRepo" ref="custRepo"></property>
</bean>
</beans>

2）将spring-repository.xml中的端口号从9200更改为9300。As 9200用于http，其中As 9300用于节点到节点通信。

3）在CustomerService.java文件中为custRepo添加getter和setter。
