好的，最后我开始完成项目的这一部分。CustomPermissionevaluator的最终代码是：

@Componentpublic class CustomPermissionevaluator implements Permissionevaluator {    public CustomPermissionevaluator() {    }    public boolean hasPermission(Authentication arg0, Object arg1) {        System.out.println("CustomPermissionevaluator.hasPermission");        System.out.println("arg0 = "+arg0);        System.out.println("arg1 = "+arg1);        if (arg0 == null || !arg0.isAuthenticated()) { System.out.println("false"); return false;        }        else { System.out.println("true"); for(GrantedAuthority authority: arg0.getAuthorities()) {     if(authority.getAuthority().equals(arg1))         return true; } return false;        }    }    @Override    public boolean hasPermission(Authentication arg0, Object arg1, Object arg2) {        System.out.println("CustomPermissionevaluator.hasPermission");        System.out.println("arg0 = "+arg0);        System.out.println("arg1 = "+arg1);        System.out.println("arg2 = "+arg2);        if (arg0 == null || !arg0.isAuthenticated()) { System.out.println("false"); return false;        }        else { System.out.println("true"); for(GrantedAuthority authority: arg0.getAuthorities()) {     if(authority.getAuthority().equals(arg2))         return true; } return false;        }    }    @Override    public boolean hasPermission(Authentication arg0, Serializable arg1, String arg2, Object arg3) {        throw new RuntimeException("Id-based permission evaluation not currently supported.");    }}
