解决了，原来是少了一节课只需要在Girl实体中添加一小段代码就行了
@NotNull(message = "成绩必填")
private Double score;
public Double getScore() {
return score;
}
public void setScore(Double score) {
this.score = score;
}

public void getAge(Integer id) throws Exception {
//Optional<Girl> girl = girlRepository.findById(id);
//Integer age = girl.getAge();
Optional<Girl> optionalGirl = girlRepository.findById(id);
Girl girl = optionalGirl.get();
Integer age = girl.getAge();
//Optional<Girl> girl = girlRepository.findById(id);
//Integer age = girl.getAge();
Optional<Girl> optionalGirl = girlRepository.findById(id);
Girl girl = optionalGirl.get();
Integer age = girl.getAge();
