On departure; #2 GEN faulted and would not reset. Complied with checklist and started APU. During cruise; APU auto-shutdown. Complied with checklist and restarted APU successfully on first attempt. Then received CABIN PRESS REG SYS 2 fault. Complied with checklist; REG SYS 1 operated normally. Although no ECAM indications were present; the Auto Fuel-Feed system had malfunctioned. With the center tank being empty; the system remained Center Tank [CTR TK] pumps instead of switching to Inner [INR] TK pumps. Fuel burned out of sequence from outer tanks until we shut down the CTR TK pumps. After this; we discussed if another event/failure occurred; we would divert to an airport with better weather than our filed destination. Contacted [dispatch] via ACARS and they concurred with either the closest or the furthest but the best weather. During descent; APU GEN went offline; but APU remained running. Shortly after; relay shuttling began and First Officer's (FO) Primary Flight Display; Navigation Display; and both ECAM displays began to flicker on and off for roughly 10 seconds. Then; received SPLR 6 FAULT SPLR 4+1 FAULT; PITCH TRIM 2 OFF; YAW DAMPER 2 OFF; TRIM TK SYS FAULT; FWS AMBER CAUTION NOT AVAILABLE; R LAT HEAT FAULT; AND R WDSL FAULT. Shortly thereafter; FO's ADC went offline; and all the above mentioned displays went blank for approximately 1 minute; then came back online. Autopilot and auto throttles disconnected. Captain assumed role of Pilot Flying and FO became pilot monitoring. We [advised] ATC and requested the ILS 16R as previously discussed. Complied with ECAM and QRH procedures as able until on final approach. Completed Normal Approach and Before Landing Checklists. Landed in visual conditions without further incident and cleared the runway. Emergency vehicles were standing by; although not specifically requested.At our departure airport moderate rain was falling during offload and unload; as well as during taxi and takeoff. After shutdown at the divert airport; maintenance and fire crews inspected the electronics and equipment bay and found water dripping from above onto Generator Control Units (GCU) and other equipment. Found evidence of water moving along the floor from the nose aft towards the belly compartments.
An A300 Captain reported numerous equipment malfunctions in flight. After landing; water was observed in the electronics compartment.
