代码重构、优化

关于代码的重构、优化，有很多技巧，我在这里记录下我遇到的问题

1. 可以采用lambda function，来解决方法内重复出现的代码，让逻辑更清晰

// 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 comment2 = generateCommentDataFunc.apply(ApproverName2);
TechnicalApproverComment comment3 = generateCommentDataFunc.apply(ApproverName3);
TechnicalApproverComment sealPersonComment = generateCommentDataFunc.apply(sealPerson);

// 通过上面的优化，可以让人一目了然，同一段代码执行了4次，干了相同的工作，只是参数不同
