最近在用postman測試postman接口，對於springmvc傳值這一塊，測試了幾種常用方式，總結一下。對於postman這個工具的使用也增加了了解。postman測試很棒，有了工具，測試接口，事倍功半。

一、單個參數傳遞

1.@RequestBody註解

1. <span style="font-family:‘KaiTi_GB2312‘;font-size:18px;"> /**
2. * 測試單個參數@RequestBody
3. */
4. @CrossOrigin
5. @RequestMapping
   (value = {"/insertTestParamsRequest"}, method = RequestMethod.GET)
6. @ResponseBody
7. public void insertTestParamsRequest(@RequestBody String name, @RequestBody String age) {
8. System.out.println("name=====" + name);
9. System.out.println("age=====" + age);
10. }
11. </span>

   /**     * 測試單個參數@RequestBody     */    @CrossOrigin    @RequestMapping(value = {"/insertTestParamsRequest"}, method = RequestMethod.GET)    @ResponseBody    public void insertTestParamsRequest(@RequestBody String name, @RequestBody String age) {        System.out.println("name=====" + name);        System.out.println("age=====" + age);    }
 

測試請求路徑

2.@RequestParam

常用來處理簡單類型的綁定，通過Request.getParameter() 獲取的String可直接轉換為簡單類型的情況（ ；
該註解有兩個屬性： value、required； value用來指定要傳入值的id名稱，required用來指示參數是否必須綁定；

1. <span style="font-family:‘KaiTi_GB2312‘;font-size:18px;"> /**
2. * 測試單個參數@RequestParam
3. */
4. @CrossOrigin
5. @RequestMapping(value = {"/insertTestParams"}, method = RequestMethod.GET)
6. @ResponseBody
7. public void insertTestParams(HttpServletRequest request, @RequestParam String name, @RequestParam String age) {
8. System.out.println("name=====" + name);
9. System.out.println("age=====" + age);
10. }</span>

 /**     * 測試單個參數@RequestParam     */    @CrossOrigin    @RequestMapping(value = {"/insertTestParams"}, method = RequestMethod.GET)    @ResponseBody    public void insertTestParams(HttpServletRequest request, @RequestParam String name, @RequestParam String age) {        System.out.println("name=====" + name);        System.out.println("age=====" + age);    }

請求路徑：

3.@PathVariable註解

路徑為resultful風格，將參數當做請求路徑。

當使用@RequestMapping URI template 樣式映射時， 即 Url/{paramId}, 這時的paramId可通過 @Pathvariable註解綁定它傳過來的值到方法的參數上。

1. <span style="font-family:‘KaiTi_GB2312‘;font-size:18px;"> /**
2. * 測試單個參數@PathVariable
3. */
4. @CrossOrigin
5. @RequestMapping(value = {"/insertTest/{name}/{age}"}, method = RequestMethod.GET)
6. @ResponseBody
7. public void insertTestPathVeriable(HttpServletRequest request, @PathVariable("name") String name, @PathVariable String age) {
8. System.out.println("name=====" + name);
9. System.out.println("age=====" + age);
10. }</span>

   /**     * 測試單個參數@PathVariable     */    @CrossOrigin    @RequestMapping(value = {"/insertTest/{name}/{age}"}, method = RequestMethod.GET)    @ResponseBody    public void insertTestPathVeriable(HttpServletRequest request, @PathVariable("name") String name, @PathVariable String age) {        System.out.println("name=====" + name);        System.out.println("age=====" + age);    }

上面代碼把URI template 中變量 name的值和age的值，綁定到方法的參數上。若方法參數名稱和需要綁定的uri template中變量名稱不一致，需要在@PathVariable("name")指定uri template中的名稱。

二、傳遞pojo對象

1.@RequestBody註解

1. <span style="font-family:‘KaiTi_GB2312‘;font-size:18px;"> /*測試添加實體*/
2. @CrossOrigin
3. @RequestMapping(value = {"/insertEntityTest"}, method = RequestMethod.POST)
4. @ResponseBody
5. public void insertEntityTest(@RequestBody CurriculumScheduleEntity curriculumScheduleEntity) {
6. System.out.println("name=====" + curriculumScheduleEntity.getClassId());
7. System.out.println("age=====" + curriculumScheduleEntity.getTeachclassId());
8. }</span>

    /*測試添加實體*/    @CrossOrigin    @RequestMapping(value = {"/insertEntityTest"}, method = RequestMethod.POST)    @ResponseBody    public void insertEntityTest(@RequestBody CurriculumScheduleEntity curriculumScheduleEntity) {        System.out.println("name=====" + curriculumScheduleEntity.getClassId());        System.out.println("age=====" + curriculumScheduleEntity.getTeachclassId());    }

postman通過json格式測試

2.直接寫實體

1. <span style="font-family:‘KaiTi_GB2312‘;font-size:18px;"> /*測試添加實體*/
2. @CrossOrigin
3. @RequestMapping(value = {"/insertTest"}, method = RequestMethod.POST)
4. @ResponseBody
5. public void insertTest(CurriculumScheduleEntity curriculumScheduleEntity) {
6. System.out.println("name=====" + curriculumScheduleEntity.getClassId());
7. System.out.println("age=====" + curriculumScheduleEntity.getWeekId());
8. }</span>

    /*測試添加實體*/    @CrossOrigin    @RequestMapping(value = {"/insertTest"}, method = RequestMethod.POST)    @ResponseBody    public void insertTest(CurriculumScheduleEntity curriculumScheduleEntity) {        System.out.println("name=====" + curriculumScheduleEntity.getClassId());        System.out.println("age=====" + curriculumScheduleEntity.getWeekId());    }

1. <span style="font-family:‘KaiTi_GB2312‘;font-size:18px;"><div>
2. <form action="/curriculumSchedule/insertTest" method="post">
3. classId :<input name="classId"><br>
4. teachClassId:<input name="weekId"><br>
5. <input type="submit" value="提交">
6. </form>
7. </div></span>

<div>    <form action="/curriculumSchedule/insertTest" method="post">         classId :<input  name="classId"><br>        teachClassId:<input   name="weekId"><br>        <input type="submit" value="提交">    </form></div>

postman測試格式

三、postman測試List類型參數

以List<string>為例，測試批量刪除方法，參數為List<String>。寫這個其實沒有什麽技術，但是中午在測試List接口的時候，用postman測試，格式一致寫錯，不知道用postman該怎麽測試了。所以花費了一點時間，記錄下來，思考這個工具的執行過程。
