why when i use @PostMapping the result is correct ，and when i replace it with @RequestMapping the re-CodePudding

the code is here

@ResponseBody
    //@RequestMapping(name = "getScreenRecordListByHipJointEntity",method = RequestMethod.POST)
    @PostMapping("getScreenRecordListByHipJointEntity")
    public PageResult getScreenRecordListByHipJointEntity(@RequestBody HipJointVo hipJointVo){
        return hipJointScreenService.getScreenRecordListByHipJointEntity(hipJointVo);
    }

when i request this Api which use PostMapping annotation,the result code is ok and nothing wrong. but when i replace the annotation @PostMapping("getScreenRecordListByHipJointEntity") with @RequestMapping(name = "getScreenRecordListByHipJointEntity",method = RequestMethod.POST),HTTP request code is 404.

the requestBody have nothing change,all the data is exactly the same.

and this is how i do the post request in postman

CodePudding user response：

The problem is that you're using the name parameter of @RequestMapping, which isn't what you're intending. Instead, you should use value (which is the default parameter the value is applied to if you don't specify, as in your @PostMapping version) or path (which is a Spring alias to make the code more readable).

CodePudding user response：

@RequestMapping and @PostMapping's default parameter is value and value is aliasFor path. Both parameter are for path mapping.

@PostMapping("getScreenRecordListByHipJointEntity") == @RequestMapping(value = "getScreenRecordListByHipJointEntity", method = RequestMethod.POST)
