I have added spring 'spring-boot-starter-security' to existing spring boot project ; after that the post methods in spring rest controller not working properly it shows a error something like this :

```

```

my controller method is this:

```
@RequestMapping(value="/authenticate",method = {RequestMethod.POST})
public  LinkedHashMap<String,Object> authenticate(@RequestBody UserCredentials user){

    LinkedHashMap<String, Object> res =new LinkedHashMap<String, Object>();
    //business logic 
    return res;
}

```
