我可以在Liferay实体中保存对象吗？

我已经通过service.xml创建了Liferay实体。我可以将JSON对象保存在字符串列中并像API一样返回此值吗？现在，对“ JSON”的响应是这样的：

{
    "name": "test",
    "time": 1656067273906,
    "longitude": 00.00000,
    "latitude": 00.00000,
    "Json": "{"name":"test", "depth":"0", "main":"true", "power":"0"}",
    "description": "test",
}

但是我希望在没有引号的情况下获得“ json”价值，例如：

{
        "name": "test",
        "time": 1656067273906,
        "longitude": 00.00000,
        "latitude": 00.00000,
        "Json": {"name":"test", "depth":"0", "main":"true", "power":"0"},
        "description": "test",
}

I have created liferay entity by service.xml. Can I save Json object inside string column and return this value like object from api? Now the response for "json" is this:

{
    "name": "test",
    "time": 1656067273906,
    "longitude": 00.00000,
    "latitude": 00.00000,
    "Json": "{"name":"test", "depth":"0", "main":"true", "power":"0"}",
    "description": "test",
}

But I hope to obtain "json" value without quotes, like this:

{
        "name": "test",
        "time": 1656067273906,
        "longitude": 00.00000,
        "latitude": 00.00000,
        "Json": {"name":"test", "depth":"0", "main":"true", "power":"0"},
        "description": "test",
}

如果您在service.xml中编写的实体具有远程服务属性设置为true，例如，

<entity name="Employee" local-service="true" remote-service="true" uuid="true" trash-enabled="true">

和一个名为的文本字段info（例如）在其中存储一个JSON字符串，然后可以在＆lt;您的服务模块src＆gt;/service/impl/employeeserviceimpl.java中编写方法包含来自服务实体的数据。例如，您可以将方法添加到employserviceimpl

public JSONObject myCustomMethod(long entityId) throws Exception {
    Employee employee EmployeeLocalServiceUtil.getEmployee(entityId);
    JSONObject result = JSONFactoryUtil.createJSONObject();
    result.put("name", employee.getName());
    result.put("Json", JSONFactoryUtil.createJSONObject(employee.getInfo()));
    return result;
}

之后，运行buildservice任务，然后构建 deploy> exploy 捆。您会找到mycustompothod作为JSONWS API。

If the entity you wrote in service.xml has the remote-service attribute set to true, for example

<entity name="Employee" local-service="true" remote-service="true" uuid="true" trash-enabled="true">

and a text field named info (for example) in which you store a JSON string, then you can write a method in <your service module src>/service/impl/EmployeeServiceImpl.java that returns a JSONObject containing the data from your service entities. For example you can add a method to EmployeeServiceImpl class

public JSONObject myCustomMethod(long entityId) throws Exception {
    Employee employee EmployeeLocalServiceUtil.getEmployee(entityId);
    JSONObject result = JSONFactoryUtil.createJSONObject();
    result.put("name", employee.getName());
    result.put("Json", JSONFactoryUtil.createJSONObject(employee.getInfo()));
    return result;
}

After that, run the buildService task then build and deploy your bundles. You will find myCustomMethod as JSONWS Api.
