拦截处理类：

public class MyInterceptor implements MethodInterceptor {
    @Override
    public Object invoke(MethodInvocation methodInvocation) throws Throwable {
        if (条件判断) {
            JSONObject jsonObject = new JSONObject();
            jsonObject.put("error", "失败返回");
            return jsonObject;
        }
        return methodInvocation.proceed();
    }
}
