小贝子编程

创建 Bean 时出错 - 嵌套异常是 java.lang.stackoverflow 错误 spring data e



我正在尝试在我的Spring MVC项目中配置Spring Data Elasticsearch。我正在遵循 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();
        }
    }
}

我正在尝试将MerchantRepository自动连接到MerchantService.

商家存储库.java

public interface MerchantRepository extends ElasticsearchRepository<Merchant, Integer> {
}

商户服务.java

@Transactional
@Service
public class MerchantService {
    @Autowired
    private MerchantDao merchantDao;
    @Autowired
    private MerchantRepository merchantRepository;
    public String addMerchant(Merchant merchant){   
        merchantRepository.save(merchant);      
        return "success";
    }
}

但自动布线失败，出现以下异常：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'merchantService' defined in file [D:Hemraj-Devapache-tomcat-7.0.57webappsestoreWEB-INFclassescomestoreserviceMerchantService.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？我想我在配置中缺少一些东西。

我也有类似的问题。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;
    ...
}

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

我遇到了同样的错误，但是在不同的Web应用程序和不同的bean创建中（我假设您的应用程序也是一个Web应用程序），我的应用程序是onebusaway/oba。以下是我在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"抛出此错误是为了表明由于深度递归，应用程序的堆栈已耗尽。

溶液：

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

  4. 在"VM 参数"框中粘贴此行（根据您的环境对其进行相应更改） 

    -Dcatalina.base="C:Program3workspace.metadata.pluginsorg.eclipse.wst.server.coretmp2
-Dcatalina.home="C:Program3tomcat7" 
-Dwtp.deploy="C:Program3workspace.metadata.pluginsorg.eclipse.wst.server.coretmp2wtpwebapps
-Djava.endorsed.dirs="C:Program3tomcat7endorsed" -Xms256m -Xmx1g -XX:MaxPermSize=2g

  5. 单击"应用"和"确定"，然后再次在 Eclipse 服务器选项卡中停止并启动服务器。

它对我有用。

注意：

这里要记住的关键是：

  1. 就我而言，我的雄猫的记忆有问题
  2. 因此，我像这样增加了内存大小，-Xms256m -Xmx1g -XX:MaxPermSize=2g我有 16GB 可用。要了解 Java 内存设置，请阅读此内容

希望对您有所帮助。
