  • UI5-技术篇-Expand与Deep 服务测试

    1.SEGW创建服务

    2.创建Data Model

    2.1Entity Types

    　ZRICO_USR 设置主键、排序字段、过滤字段

     ZRICO_USRITM设置主键 

    2.2Associations

    　创建associations，设置主要实体 ZRICO_USR ,依赖实体ZRICO_USRITM，两者对应关系N:M

    0：0...1 记录可有可无，最多一条记录

    1：1必须存在一条记录

    M：0..n记录可有可无，可有n条记录

    N：1...n至少存在一条记录，可有n条记录

    主表与从表字段关联关系，如上图。

    2.3Navigation Properties

    3.Service Implementation

    4.Runtime Artifacts

    5.类方法重写
