Question

我在配置spring数据elasticsearch时遇到问题，我按照这里提到的程序Spring bean configuration for Crud Repositories进行了操作。但是我收到了错误：

线程中的异常＆＃34; main＆＃34; org.springframework.beans.factory.BeanCreationException：错误创建名为＆＃39; customerService＆＃39;：注入资源的bean 依赖失败;嵌套异常是 org.springframework.beans.factory.BeanCreationException：错误使用名称＆＃39; customerRepo＆＃39;创建bean：无法解析引用 bean＆＃39; elasticsearchTemplate＆＃39;设置bean属性时＆＃39; elasticsearchOperations＆＃39 ;;嵌套异常是 org.springframework.beans.factory.BeanCreationException：错误创建名为＆＃39; elasticsearchTemplate＆＃39;在类路径中定义 resource [spring-repository.xml]：bean的实例化失败;嵌套异常是org.springframework.beans.BeanInstantiationException：无法实例化bean类 [org.springframework.data.elasticsearch.core.ElasticsearchTemplate]：构造函数抛出异常;嵌套异常是 java.lang.NoSuchMethodError： com.fasterxml.jackson.core.JsonFactory.requiresPropertyOrdering（）z

以下是代码：

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;
}
}

CustomerRepo.java

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

MainClass.java

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);
}
}

弹簧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" />

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

</beans>

弹簧的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。

Answer 1

在修改这些文件后，它最终起作用了：

1）spring-customer.xml

images

2）更改端口号spring-repository.xml中的9200到9300。因为9200用于http，其中9300用于节点到节点的通信。

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