所有 RestController将会集成 CommonRestController

        
package cn.netkiller.api.rest;

import org.springframework.http.HttpStatus;
import org.springframework.security.core.annotation.AuthenticationPrincipal;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseStatus;

public class CommonRestController {

@RequestMapping("ping")
@ResponseStatus(HttpStatus.OK)
public String welcome() {
    return "PONG";
}

@RequestMapping("commit")
public String commit() {
    return "$Id$";
}

@RequestMapping("auth")
@ResponseStatus(HttpStatus.OK)
public String auth(@AuthenticationPrincipal final UserDetails user) {
    return String.format("%s: %s %s", user.getUsername(), user.getPassword(), user.getAuthorities());
}
}
