public class AddressBookAccessToken implements Interceptor {
@Inject
WxTokenService wxTokenService;
@Override
public void intercept(Invocation invocation) {
Controller controller = invocation.getController();
Result result = wxTokenService.checkAccessToken(WxTokenService.ADDRESS_BOOK);
if (result.errcode == 0) {
invocation.invoke();
} else {
controller.renderJson(result);
}
}
}
如上：通过
Result result = wxTokenService.checkAccessToken(WxTokenService.ADDRESS_BOOK);
可以拿到一个访问令牌 result.access_token。
@Before(AddressBookAccessToken.class)
public void test() {
String access_token = getPara("access_token");
//...
}

添加 @Para 参数也可以做到：
Para para = inv.getMethod().getAnnotation(Para.class);
if (para != null) {
Object value = para.value();
}
