以JSON为参数的非托管扩展 [英] Unmanaged extensions taking JSON as parameter
问题描述
我正在尝试构建扩展以动态地将一些数据插入neo4j中.
I'm trying to build an extension to dynamically insert some data in neo4j to no avail.
这是我的扩展代码:
@Path("/inserter")
public class Inserter {
private final GraphDatabaseService db;
public Inserter(@Context GraphDatabaseService db){
this.db = db;
}
@POST
@Consumes(MediaType.APPLICATION_JSON)
@Path("/insert")
public void insert(Person x){
Transaction tr = db.beginTx();
//Do something
tr.success();
tr.finish();
}
}
这是我的Person对象:
And this is my Person object :
package org.neo4j.server.plugin.plugin.messages;
public class Person {
public String name;
public int id;
public String email;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
}
我尝试了许多不同的方法，但到目前为止都没有奏效.上面的代码出现415错误，提示不支持的媒体类型"
I tried a lot of different methods but none worked so far. With the code above a get a 415 error saying "Unsupported Media Type"
我试图将jackson json提供程序添加到我的项目中.它改变了我的错误，但我不知道如何处理.现在的错误是:
I tried to add the jackson json provider to my project. It changed my error but I cannot figure out how to handle this. The error is now :
错误500 com.fasterxml.jackson.databind.ObjectWriter.getFactory()Lcom/fasterxml/jackson/core/JsonFactory;
Error 500 com.fasterxml.jackson.databind.ObjectWriter.getFactory()Lcom/fasterxml/jackson/core/JsonFactory;
java.lang.NoSuchMethodError:com.fasterxml.jackson.databind.ObjectWriter.getFactory()Lcom/fasterxml/jackson/core/JsonFactory;
java.lang.NoSuchMethodError: com.fasterxml.jackson.databind.ObjectWriter.getFactory()Lcom/fasterxml/jackson/core/JsonFactory;
要测试我的扩展程序，我正在使用Google REST控制台，将RequestUri设置为localhost:7474/myextensions/inserter/insert，将Content-Type设置为application/json，而Request主体如下:
To test my extension I'm using the Google REST console, setting the RequestUri as localhost:7474/myextensions/inserter/insert, the Content-Type as application/json and the Request body is the following :
{"id":100，"name":"Bibi"，"email":"yopmail"}
{"id":100,"name":"Bibi","email":"yopmail"}
这是Maven依赖树(不确定由于引起问题而更改了很多代码的原因，这完全引起了我的麻烦)
EDIT : Here is the maven dependency tree (not sure it was exactly the same that caused me trouble because I changed lot of code since my question)

推荐答案
错误不支持的媒体类型"是由于您的方法和ajax调用中存在某些不匹配.在这里，我可以看到您的方法是发布方法，因此您必须以发布格式调用此方法.
The error "Unsupported Media Type" is due to there is some mismatch in your methos and in your ajax call. Here I can see your method is post, so you have to call this method by post format.
看看是否有效.
json_array * = [{"id":100，"name":"Bibi"，"email":"yopmail"}]
json_array*= [{"id":100,"name":"Bibi","email":"yopmail"}]
$.ajax({
type:'POST',
url :'http://localhost:8080/inserter/insert',
cache: false,
contentType: "application/json",
dataType: 'json',
data:json_array,
success:function(data){},
error:function(response,status) {}
});
