Plan

RepairPlan[repairTarget=补齐 OrderService.calculateUnitPrice 的 quantity 参数校验, rootCauseHypothesis=quantity 为 0 时直接执行除法触发 ArithmeticException,未按契约抛出 IllegalArgumentException。, suspectedFiles=[target-service/src/main/java/com/example/targetservice/service/OrderService.java, target-service/src/test/java/com/example/targetservice/service/OrderServiceTest.java, target-service/src/test/java/com/example/targetservice/controller/OrderControllerTest.java], steps=[在 OrderService.calculateUnitPrice 开头校验 quantity <= 0,抛出包含 quantity 的 IllegalArgumentException。, 保留合法入参的 totalCents / quantity 计算逻辑不变。, 运行 target-service 测试验证 service 层异常与 controller 层 400 响应。], testCommand=mvn -pl target-service test]

Review

Patch is limited to target-service and tests pass.
