can xsd schema validate encoding, e.g. UTF-8, possible?

问题 By using schema, is there any simple/easy way to validate the encoding of an xml msg? Assuming the 1st line of xml is "not" trustworthy? e.g. ignore ?xml version="1.0" encoding="UTF-8" ? 回答1: No, schema can't dictate encoding type except in terms of the binary data element types, but this encoding is still going to be encapsulated by the high level encoding of the document itself. This makes sense if you realize that the schema is suppose to describe the information and not the transport

DB Design for Choosing One of Multiple Possible Foreign Tables

由 丶灬走出姿态 提交于 2019-12-31 02:34:06
问题 Say if I have two or more vastly different objects that are each represented by a table in the DB. Call these Article, Book, and so on. Now say I want to add a commentening feature to each of these objects. The comments will behave exactly the same in each object, so ideally I would like to represent them in one table. However, I don't know a good way to do this. The ways I know how to do this are: Create a comment table per object. So have Article_comments, Book_comments, and so on. Each

Use conditional statements on json schema based on another schema object

问题 I have a json object like: { "session": { "session_id": "A", "start_timestamp": 1535619633301 }, "sdk": { "name": "android", "version": "21" } } The sdk name can either be android or ios . And the session_id is based on name field in sdk json . I have written a json schema using conditional statement (Using draft 7) as follows: But it works in an unexpected manner: { "$schema": "http://json-schema.org/draft-07/schema#", "$ref": "#/definitions/Base", "definitions": { "Base": { "type": "object"

SQL Server 2008 - Removing schema ownership

由 痞子三分冷 提交于 2019-12-30 20:38:21
问题 I just created a new web application that accepts some form based input from the user and inserts it in into the database. To go along with this I created a new user in the database and initially assigned the user to two roles and schemas ... db_datareader db_datawriter After thinking things over I realized the user did not need to be part of the db_datareader role because the user only inserted data into the database and never read any. So I went back and removed the role of db_datareader

Polymorphic schema validation in Clojure

由 不问归期 提交于 2019-12-30 17:17:48
问题 I want to use a schema to validate a request object. One of the values in the map determines which other fields are valid. For example, these would all be valid: { :name "jane" :type :dog :barking true } { :name "alan" :type :bird :cheeping true } { :name "bert" :type :fish :swimming true } Some fields are common. But others depend upon the value of :type . For example, this would be invalid: { :name "phil" :type :bird :barking false } How can such schema be expressed? I'm happy to use either

How to use alternatives in XML Schema 1.1

问题 From everything I have read, the schema I have defined below should work (emphasis on alternatives). I get the following error: The 'http://www.w3.org/2001/XMLSchema:alternative' element is not supported in this context. Could you please point out what I did wrong? Here is my current schema: <?xml version="1.0" encoding="utf-8"?> <xs:schema targetNamespace="http://tempuri.org/XMLSchema.xsd" elementFormDefault="qualified" xmlns="http://tempuri.org/XMLSchema.xsd" xmlns:mstns="http://tempuri.org

打开BeanFactory ignoreDependencyInterface方法的正确姿势

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 在阅读Spring容器扩展部分源码的过程中，我了解到BeanFactory接口中有个方法叫ignoreDependencyInterface。从官方文档的“字面”来看，其作用指定自动装配(autowiring)的时候忽略的接口。还有一个很相似的方法叫ignoreDependencyType，同样其官方字面意思是指自动装配(autowiring)的时候忽略的类。 究竟这两个方法是不是我们的理解相同呢？真的可以让指定的接口和类在自动装配的时候被忽略？有没有注意不到的坑？ /** * Ignore the given dependency interface for autowiring. * <p>This will typically be used by application contexts to register * dependencies that are resolved in other ways, like BeanFactory through * BeanFactoryAware or ApplicationContext through ApplicationContextAware. * <p>By default, only the BeanFactoryAware interface

1.Spring 的 AOP 简介 1.1 什么是 AOP AOP 为 Aspect Oriented Programming 的缩写，意思为面向切面编程，是通过预编译方式和运行期动态代理实现程序功能的统一维护的一种技术。 1.2 AOP 的作用及其优势 作用：在程序运行期间，在不修改源码的情况下对方法进行功能增强 优势：减少重复代码，提高开发效率，并且便于维护 1.3 AOP 的底层实现 实际上，AOP 的底层是通过 Spring 提供的的动态代理技术实现的。在运行期间，Spring通过动态代理技术动态的生成代理对象，代理对象方法执行时进行增强功能的介入，在去调用目标对象的方法，从而完成功能的增强。 1.4 AOP 的动态代理技术 常用的动态代理技术 JDK 代理 : 基于接口的动态代理技术 cglib 代理：基于父类的动态代理技术 [外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-eZfexG26-1577666296837)(img\图片1.png)] 1.5 JDK 的动态代理 ①目标类接口 public interface TargetInterface { public void method ( ) ; } ②目标类 public class Target implements TargetInterface { @Override

Validating against a Schema with JAXB

由 最后都变了- 提交于 2019-12-30 05:59:13
问题 I've been looking for solutions to this problem for far too long considering how easy it sounds so I've come for some help. I have an XML Schema which I have used with xjc to create my JAXB binding. This works fine when the XML is well formed. Unfortunately it also doesn't complain when the XML is not well formed. I cannot figure out how to do proper full validation against the schema when I try to unmarshall an XML file. I have managed to use a ValidationEventCollector to handle events,
