用一个类名调用它中的静态方法

@Component 
public  class WhoFunctionControl {

@Autowired
private  FunctionService  functionService;
@Autowired

public void setFunctionService( FunctionService  functionService) {

@PostConstruct

whoFunctionControl.functionService = this.functionService; 
whoFunctionControl.whoFunctionService = this.whoFunctionService;
} 

public static void  insertWhoFunction (String userid,int daihao) {
