我想测试包含请求主体的请求类型发布的rest控制器方法。所有其他“获取方法”均正常工作。我期望200 OK，但返回417。我的目的是使其通过 我运行测试，但失败了。我是新手。有人可以解释一下为什么失败以及如何使其通过

Objects.requireNonNull(loan,"Loan can not be null");
Loan loan1 = loanRepository.save(loan);
if (loan1 != null)

答案 0 :(得分：1)
似乎loanRepository.save(loan)返回的是null。
您是否尝试调试测试？
答案 1 :(得分：0)
我通过模拟服务类来解决问题
when(loanService.createLoan(any(Loan.class))).thenReturn(true);
