在Spring Data Neo4j中为Long字段抛出MappingException

时间：2015-08-10 16:13:23

标签： spring neo4j spring-data-neo4j-4

使用SDN 4.0.0.RC1我有一个简单的NodeEntity类可以保存，但我无法检索它。从Neo4J

中检索时，siteId字段看起来像是一个整数 
import org.neo4j.ogm.annotation.Index;
import org.neo4j.ogm.annotation.NodeEntity;
import org.neo4j.ogm.annotation.Property;

@NodeEntity
public class Institution extends BaseEntity {
    @Property(name="name")
    @Index(unique = true)
    public String name;

    public Long siteId;

    public Institution() { }

    public Institution(String name, Long siteId) {
        this.name = name;
        this.siteId = siteId;
    }
}

public interface InstitutionRepository extends GraphRepository<Institution> {
    Institution findBySiteId(Long siteId);
}

Long siteId = 123;
Institution institution = institutionRepository.findBySiteId(siteId);

堆栈跟踪：

这是一个错误吗？

1 个答案:

答案 0 :(得分：0)

是的，这是RC1中的一个错误，它已被修复，很快就会在RC2中出现。

在此之前，您可以使用最新的快照app.controller('BlogController', ['$scope', '$http', '$modal', function($scope, $http, $modal){ $scope.blogEntry = {}; // Place holder for data (blog entry) $scope.editBlogEntry = function(blogEntry) { $scope.blogEntry = blogEntry; $scope.editModal = $modal.open({ templateUrl: '/resources/partials/editBlogModal.html', controller: 'EditBlogController', size: 'lg', resolve: { blogEntry: function() { console.log($scope.blogEntry); //this shows the object return $scope.blogEntry; } } }); }; }]); app.controller('EditBlogController', ['$scope', '$http', '$modalInstance', function($scope, $http, $modalInstance, blogEntry){ $scope.blogEntry = blogEntry; console.log($scope.blogEntry); //undefined }])
