我正在用Spring-data-rest开发一个应用程序。我正在测试来自POSTMAN客户端的POST请求,以测试数据是否插入到我的数据库DB.In中我有一个cartItems表。我可以在发布JSON的同时发布数据,如下所示:商品、购物车和merchandiseType是外键引用。
{
"rate": 500,
"quantity": 1,
"amount": 500,
"createdAt": "2015-04-12T23:40:00.000+0000",
"updatedAt": "2015-04-14T21:35:20.000+0000",
"merchandise": "http://localhost:8080/sportsrest/merchandises/10",
"cart":"http://localhost:8080/sportsrest/carts/902",
"merchandiseType":"http://localhost:8080/sportsrest/merchandiseTypes/1"
}但是,当我像下面这样发布数据时,我得到了错误:我放置了商品JSON,而不是商品的URL,这是我已经测试过的商品请求表JSON:
{
"rate": 500,
"quantity": 1,
"amount": 500,
"createdAt": "2015-04-12T23:40:00.000+0000",
"updatedAt": "2015-04-14T21:35:20.000+0000",
"merchandise": {
"id": 4,
"shortDescription": "white football",
"rate": 500,
"updatedAt": "2015-04-24T18:30:00.000+0000",
"createdAt": "2015-04-20T18:30:00.000+0000",
"longDescription": "test description for binary 1001",
"type": "1"
},
"cart":"http://localhost:8080/sportsrest/carts/902",
"merchandiseType":"http://localhost:8080/sportsrest/merchandiseTypes/1"}
我收到以下错误:
{
"cause": {
"cause": {
"cause": null,
"message": "Template must not be null or empty!"
},
"message": "Template must not be null or empty! (through reference chain: co.vitti.sports.bean.CartItem[\"merchandise\"])"
},
"message": "Could not read JSON: Template must not be null or empty! (through reference chain: co.vitti.sports.bean.CartItem[\"merchandise\"]); nested exception is com.fasterxml.jackson.databind.JsonMappingException: Template must not be null or empty! (through reference chain: co.vitti.sports.bean.CartItem[\"merchandise\"])"
}有人能帮我解释一下为什么会出现这个错误吗?谢谢。

我猜您没有提供内容类型:应用程序/json头。

尝试用"@RestResource(exported = false)“注释你的"MerchandiseRepository”。
