Restful和CXF结合简单案例

一个适用于简单操作的接口规范而已，无规矩不成方圆，复杂操作并不适用，还是看业务发展需求的

它适合CRUD并且只适合CRUD，有的浏览器可能不支持POST、GET之外的提交方式，要特殊处理，API容易给让误解中能进行增、删、查、改等操作。

RESTful风格只是一种架构风格，一种思想，我们不能一概的说它的好或不好。存在即合理，在[软件开发][Link 1]过程中，无论是采用RPC风格还是RESTful，只要是适合自己业务就是最好的

CXF 支持多种“Frontend”编程模型，CXF 实现了JAX-WSAPI （遵循 JAX-WS 2.0 TCK 版本），它也包含一个“simple frontend”允许客户端和 EndPoint 的创建，而不需要 [Annotation][] 注解。CXF 既支持WSDL优先开发，也支持从 Java 的代码优先开发模式。容易使用： CXF 设计得更加直观与容易使用。有大量简单的 API 用来快速地构建代码优先的 Services，各种 Maven 的插件也使集成更加容易，支持 JAX-WS API ，支持 Spring 2.0 更加简化的 XML 配置方式，等等。支持二进制和遗留协议：CXF 的设计是一种可插拨的架构，既可以支持 XML ，也可以支持非 XML 的类型绑定，比如：JSON 和 CORBA

首先创建一个maven的web工程，本项目中展示了两种格式的数据User是xml的，Product是json的，下面进行代码展示：

编码工具类：（可以不需要）：

    import org.slf4j.LoggerFactory;
    
    
    public class EncodingLoggingInInterceptor extends LoggingInInterceptor {
    
        private Logger log = LoggerFactory.getLogger(getClass());
    
        /**

         */
        public EncodingLoggingInInterceptor() {
            // TODO Auto-generated constructor stub
            super();
        }
    
        /**
         * @see org.apache.cxf.interceptor.LoggingInInterceptor#handleMessage(org.apache.cxf.message.Message)
         */
        @Override
        public void handleMessage(Message message) throws Fault {
            // TODO Auto-generated method stub
    
            String encoding = System.getProperty("file.encoding");
            encoding = encoding == null || encoding.equals("") ? "UTF-8" : encoding;
    
            log.debug("encoding : " + encoding);
            message.put(Message.ENCODING, encoding);
    
            super.handleMessage(message);
        }
    }

接下来就是把项目打成war包或者其他放到服务器上去，然后再进行自己编写服务端进行调用，下面是用postman直接调用的结果：

自己也可以在后台编写客户端进行调用：
