环境

系统: windows 11
工具: java, idea, git bash

Controller

接口常见有以下几种方式

其中： Tobj

调用脚本

我的是windows 系统，使用 git bash 窗口运行, 用 cmd 或者 power shell 会有问题

curl -X GET 'http://localhost:18011/.../testTobjBody?dateVal=dateVal&mark=mark' curl -X POST 'http://localhost:18011/.../testTobjBody' -H 'Content-Type: application/x-www-form-urlencoded' --data 'mark=mark&dateVal=dateVal'curl -X POST 'http://localhost:18011/.../testTobjBody' -H 'Content-Type: application/json' --data-raw '{"dateVal":"dateVal","mark":"mark"}'

运行结果

红框标注说明是有问题

testMap(String mark,String dateVal,HttpServletRequest request)

testMap(Map map,HttpServletRequest request)

testTobj(Tobj tobj, HttpServletRequest request)

testMapBody(@RequestBody Map map,HttpServletRequest request)

testTobjBody(@RequestBody Tobj tobj, HttpServletRequest request)

总结

使用 (String mark,String dateVal, HttpServletRequest request) 和 (Tobj tobj, HttpServletRequest request) 结果一样，GET 和 POST(application/x-www-form-urlencoded) 都可获取参数值

使用 (@RequestBody Map map, HttpServletRequest request) 和 (@RequestBody Tobj tobj, HttpServletRequest request) 结果一样，POST(application/json) Map，Tobj 可获取参数值, 但 HttpServletRequest 获取不到参数值

使用(Map map, HttpServletRequest request) 三种调用，Map都获取不到参数值, 但HttpServletRequest 可获取值
