Question

我的spring boot REST控制器中有2个方法

这是我的REST CONTROLLER代码

@RestController
public class MainRestController {

@RequestMapping(value = "/",method=RequestMethod.POST)
public String startMigration(){
        return "POSt";
}

@RequestMapping(value = "/",method=RequestMethod.PATCH)
public String PUT(){
        return "PUT";
}

/*
 * If i commnet this method and un comment following method it will run
 * */
@RequestMapping(value = "/{name}",method=RequestMethod.PUT)
public String PATCH(@PathVariable String name){
        return "PATCH";
}

/*@RequestMapping(value = "/",method=RequestMethod.PATCH)
public String PATCH(){
        return "PATCH";
}*/

@RequestMapping(value = "/",method=RequestMethod.DELETE)
public String DELETE(){
        return "DELETE";
}
}

这是我的CONTROLLER代码

@Controller
public class MainController {

@RequestMapping(value = "/",method=RequestMethod.GET)
public String getMainPage(){
    return "index.html";
}
}

现在问题是我点击PATCH请求 http://localhost:8080/ 它返回

{
"timestamp": 1486041782895,
"status": 405,
"error": "Method Not Allowed",
"exception":"org.springframework.web.HttpRequestMethodNotSupportedException",
"message": "Request method 'PATCH' not supported",
"path": "/"
}

当我点击GET请求http://localhost:8080/时，它会返回

Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Method Not Allowed, status=405).
Request method 'GET' not supported

任何人都可以告诉我原因吗？

现在问题是当我点击PATCH请求http://localhost:8080/时它返回

{
"timestamp": 1486041782895,
"status": 405,
"error": "Method Not Allowed",
"exception":"org.springframework.web.HttpRequestMethodNotSupportedException",
"message": "Request method 'PATCH' not supported",
"path": "/"
}

发生此错误是因为您声明了一种方法，该方法需要方法中的PathVariable。

如果您希望它在不传递变量的情况下工作，您应该执行以下操作：

@RequestMapping(method=RequestMethod.PATCH)
public @ResponseBody String patch(@RequestParam(name = "name", required = false) String name){
    return "ANOTHER PATCH";
}

所以这个PATCH请求http://localhost:8080/应该返回＆＃34;另一个补丁＆＃34;

这是你的问题吗？
