Java 项目列表请求设置优化：使用 Switch 语句提高效率

public static List getAllProjectList(List projects) {\n for (Project project : projects) {\n switch (project.projectId) {\n case 1:\n project.setRequest("");\n break;\n case 20:\n project.setRequest("");\n break;\n case 2:\n project.setRequest(getRequest2());\n break;\n case 3:\n project.setRequest(getRequest3());\n break;\n case 4:\n project.setRequest(getRequest4());\n break;\n case 5:\n project.setRequest(getRequest5());\n break;\n case 6:\n project.setRequest(getRequest6());\n break;\n case 7:\n project.setRequest(getRequest7());\n break;\n case 8:\n project.setRequest(getRequest8());\n break;\n case 9:\n project.setRequest(getRequest9());\n break;\n case 10:\n project.setRequest(getRequest10());\n break;\n case 11:\n project.setRequest(getRequest11());\n break;\n case 12:\n project.setRequest(getRequest12());\n break;\n case 13:\n project.setRequest(getRequest13());\n break;\n case 14:\n project.setRequest(getRequest14());\n break;\n case 15:\n project.setRequest(getRequest15());\n break;\n case 16:\n project.setRequest(getRequest16());\n break;\n case 17:\n project.setRequest(getRequest17());\n break;\n case 18:\n project.setRequest(getRequest18());\n break;\n case 19:\n project.setRequest(getRequest19());\n break;\n case 21:\n project.setRequest(getRequest21());\n break;\n case 22:\n project.setRequest(getRequest22());\n break;\n case 23:\n project.setRequest(getRequest23());\n break;\n case 24:\n project.setRequest(getRequest24());\n break;\n case 25:\n project.setRequest(getRequest25());\n break;\n case 26:\n project.setRequest(getRequest26());\n break;\n case 27:\n project.setRequest(getRequest27());\n break;\n case 28:\n project.setRequest(getRequest28());\n break;\n case 29:\n project.setRequest(getRequest29());\n break;\n case 30:\n project.setRequest(getRequest30());\n break;\n case 31:\n project.setRequest(getRequest31());\n break;\n case 32:\n project.setRequest(getRequest32());\n break;\n case 33:\n project.setRequest(getRequest33());\n break;\n case 34:\n project.setRequest(getRequest34());\n break;\n case 35:\n project.setRequest(getRequest35());\n break;\n case 36:\n project.setRequest(getRequest36());\n break;\n case 37:\n project.setRequest(getRequest37());\n break;\n case 38:\n project.setRequest(getRequest38());\n break;\n }\n }\n return projects;\n}
