關於程式碼的重構、優化，有很多技巧，我在這裡記錄下我遇到的問題

1. 可以採用lambda function，來解決方法內重複出現的程式碼，讓邏輯更清晰

// old
TechnicalApproverComment comment1 =  new TechnicalApproverComment();
comment1.setCreateByName(ApproverName1.getRealName());
comment1.setCreateBy(ApproverName1.getPersonnelInfoCode());
TechnicalApproverComment comment2 =  new TechnicalApproverComment();
comment2.setCreateByName(ApproverName2.getRealName());
comment2.setCreateBy(ApproverName2.getPersonnelInfoCode());
TechnicalApproverComment comment3 =  new TechnicalApproverComment();
comment3.setCreateByName(ApproverName3.getRealName());
comment3.setCreateBy(ApproverName3.getPersonnelInfoCode());
TechnicalApproverComment sealPersonComment =  new TechnicalApproverComment();
sealPersonComment.setCreateByName(sealPerson.getRealName());
sealPersonComment.setCreateBy(sealPerson.getPersonnelInfoCode());

// new
Function<BasePersonnelInfoVO, TechnicalApproverComment> generateCommentDataFunc = (BasePersonnelInfoVO person) -> {
    TechnicalApproverComment comment = new TechnicalApproverComment();
    comment.setCreateByName(person.getRealName());
    comment.setCreateBy(person.getPersonnelInfoCode());
    return comment;
};
TechnicalApproverComment comment1 = generateCommentDataFunc.apply(ApproverName1);
TechnicalApproverComment comment1 = generateCommentDataFunc.apply(ApproverName2);
TechnicalApproverComment comment1 = generateCommentDataFunc.apply(ApproverName3);
TechnicalApproverComment sealPersonComment = generateCommentDataFunc.apply(sealPerson);

// 通過上面的優化，可以讓人一目瞭然，同一段程式碼執行了4次，幹了相同的工作，只是引數不同
