我正在尝试将模型的一部分作为json存储在我的db中。ebean应该有这个助手:
@DbJson
public Map<String, Object> jsonContent;
但是当我试图储存我的豆子时,它只有在我不给它时间的情况下才起作用 jsonContent
现场。当我试图设置它时,我得到以下错误:

我的豆子看起来像这样:
@Entity
@Table(name = "my_table")
public class MyBean extends AManageableModel {
public static final Finder<Long, Configuration> find = new Finder<>(MyBean.class);
@Constraints.Required
public String name;
@Constraints.Required
@JsonProperty("some_property")
public String someProperty;
@DbJson
@JsonProperty("json_content")
public Map<String, Object> jsonContent;
}
当我使用下面的json在db中创建一行时,它可以工作(并且 jsonContent
是 null
):
{
"name": "test 1",
"some_property": "some property content"
}
但当我使用以下json时:
{
"name": "test 1",
"some_property": "some property content",
"json_content": {
"test":"test",
"test2":"test2"
}
}
它崩溃了(请参阅文章开头的完整stacktrace)。
序列化是使用jackson完成的:
Json.fromJson(jsonData, MyBean.class);

好吧,那么使用:
而不是:
对我有效,所以我怀疑“object”需要扩展一些可序列化的东西。
编辑:所以,两年后我不得不使用
Map<String,Object> jsonContent
因为无法挽回的原因,同样的问题又出现了。这是一个肮脏的解决方案,在应用程序启动时称之为:这迫使
EJson
装载和问题消失。。。。但该死的是它很脏。
