我会尽力为您翻译此段文本,内容与IT技术有关。您希望使用Spring Data REST来操作elasticsearch。内置的REST控制器对于POST方法似乎无法正常工作:当我试图发布文档时出现了错误。这个问题很容易重现:
我创建了一个简单的实体:
@Document(indexName = "user", type = "user", shards = 1, replicas = 0, refreshInterval = "-1")
public class Customer {
@Id
private String id;
@Field(type = FieldType.String, store = true)
private String firstName;
@Field(type = FieldType.String, store = true)
private String lastName;
// getters and setters are skipped
}
代码仓库:
public interface UserRepository extends ElasticsearchRepository<User, String> {
}
当我尝试获取所有用户时,我得到的响应是:
curl -X GET "http://localhost:9000/users"
{
"_links" : {
"self" : {
"href" : "http://localhost:9000/users{?page,size,sort}",
"templated" : true
},
"search" : {
"href" : "http://localhost:9000/users/search"
}
},
"page" : {
"size" : 20,
"totalElements" : 0,
"totalPages" : 0,
"number" : 0
}
}
但是当我尝试添加用户时:
curl -i -X POST -H "Content-Type:application/json" http://localhost:9000/users -d '{"id":"4e9e62aa-7312-42ed-b8e4-24332d7973cd","firstName":"test","lastName":"test"}'
我遇到了一个错误:
{"cause":null,"message":"PersistentEntity must not be null!"}
这个问题似乎有一个Jira票据,但没有任何评论: Jira Issue
我想知道是否有可能避免为Spring Data Elasticsearch编写CRUD REST控制器?
