使用OmniConstructor构造的对象第二层成员变量为null

releaseDraftBiz = OmniConstructor.newInstance(ReleaseDraftBiz.class);

构造biz对象，第一层成员变量service有，但是service的成员变量mapper都为null.

Start by reproducing the reported call to OmniConstructor.newInstance(ReleaseDraftBiz.class) and inspect how the first-level service and its mapper are initialized. Trace the constructor behavior for nested members and compare the observed object with the expected fully initialized structure. Done means the second-level mapper members are no longer null in this scenario.
