spring-mvc - 创建bean时出错-嵌套异常是java.lang.stackoverflow错误spring数据elasticsearch存储库

Question

我正在尝试在我的 Spring MVC 项目中配置Spring Data Elasticsearch。我正在关注 Java 配置。以下是我在这里建议的 elasticsearch 配置类。

public class ESConfig {

    @Configuration
    @EnableElasticsearchRepositories(basePackages="com/estore/es/repository")   
    static class ElasticConfig{
        @Bean
        public ElasticsearchOperations elasticsearchTemplate() {            
            return new ElasticsearchTemplate(nodeBuilder().local(true).node().client());
        }

        @Bean
        public NodeBuilder nodeBuilder(){
            final NodeBuilder nodeBuilder = NodeBuilder.nodeBuilder();
            return nodeBuilder;     
        }

        @Bean
        public Node node(){
            return nodeBuilder().node();        
        }

        @Bean
        public Client client(){
            return node().client();
        }
    }

}

我正在尝试自动连接MerchantRepository到MerchantService.

MerchantRepository.java

public interface MerchantRepository extends ElasticsearchRepository<Merchant, Integer> {

}

MerchantService.java

@Transactional
@Service
public class MerchantService {

    @Autowired
    private MerchantDao merchantDao;

    @Autowired
    private MerchantRepository merchantRepository;

    public String addMerchant(Merchant merchant){   
        merchantRepository.save(merchant);      
        return "success";
    }

}

但自动装配失败给出以下异常：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'merchantService' defined in file [D:\Hemraj-Dev\apache-tomcat-7.0.57\webapps\estore\WEB-INF\classes\com\estore\service\MerchantService.class]: Unsatisfied dependency expressed through constructor argument with index 0 of type [com.estore.es.repository.MerchantRepository]: : Error creating bean with name 'merchantRepository': Invocation of init method failed; nested exception is java.lang.StackOverflowError; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'merchantRepository': Invocation of init method failed; nested exception is java.lang.StackOverflowError

有什么建议吗？我想我在配置中遗漏了一些东西。

我有类似的问题。我认为 Spring 在具有自引用的参数化类型的实体方面存在问题。就我而言，我有课程：

public class Input<V> {
    private Pipe<V> pipe;
    ...
}

和

public class Pipe<V> {
    private Input<V> input;
    ...
}

它产生与您相同的堆栈跟踪。我建议您检查您的Merchant类，或者它的子类，或者其中一个字段是或具有参数化类型。

我得到了同样的错误，但是在不同的 web 应用程序和不同的 bean 创建中（我假设你的应用程序也是一个 web 应用程序），我的应用程序是 onebusaway/oba。这是我在 Windows 7 开发机器上的 Eclipse Kepler 中启动 tomcat 服务器时遇到的错误：

Error creating bean with name 'transitGraphDaoImpl': Invocation of init method failed; 
nested exception is java.lang.StackOverflowError

我相信“抛出此错误表明应用程序的堆栈已用尽，由于深度递归。” 从阅读源

解决方案：

在 Eclipse Kepler IDE 的 Servers 选项卡中双击现有的 tomcat 7 服务器，将打开一个配置窗口
点击“打开启动配置”
单击“参数”选项卡

在“VM Arguments”框中粘贴此行（根据您的环境进行相应更改）

-Dcatalina.base="C:\Program3\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp2
-Dcatalina.home="C:\Program3\tomcat7" 
-Dwtp.deploy="C:\Program3\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp2\wtpwebapps
-Djava.endorsed.dirs="C:\Program3\tomcat7\endorsed" -Xms256m -Xmx1g -XX:MaxPermSize=2g

单击“应用”和“确定”，然后再次在 Eclipse Servers 选项卡中停止并启动您的服务器。

这个对我有用。

笔记：

这里要记住的关键是：

就我而言，我对tomcat的内存有疑问
因此我像这样增加了内存大小，-Xms256m -Xmx1g -XX:MaxPermSize=2g我有 16gig 可用。要了解 Java 内存设置，请阅读此

希望能帮助到你。
