step S5: and establishing the incidence relation between the plate and the component through the plate unique ID, the component type value and the component unique ID and storing the incidence relation into a database.
In the step S4, a fastjson self-contained method is adopted to convert the json character string into an entity of a component or content, and then the parameter verification is performed by using the programming verification of the Spring validity.
Compared with the prior art, the invention has the following advantages and beneficial effects:
on the basis of performing table division on the components and the content according to types, the invention establishes the association relationship between the components and the content according to the one-to-one correspondence relationship between the component types and the content types, unifies the component interface inlets and the content interface inlets, reduces the number of interfaces, maintains each type of component and content independently and ensures the integral independence of each component.

Detailed Description
The present invention will be described in further detail with reference to examples, but the embodiments of the present invention are not limited thereto.
The embodiment is as follows:
a method for realizing background attachment of a customized component of a television desktop comprises the following steps:
