CXF随笔（二）：CXF开发webservice点点

 

（1）jar最小依赖

 

参考：http://gary0416.iteye.com/blog/1222915

 

 

 

 

 

部署到tomcat,项目启动后可以看到

 

经试验，不行，可能由于我用的是cxf3.0版本，还是全部jar吧！

 

（2）@XmlRootElement(name = "FlowInfo") 注解效果

 

使用前：

 

 

 

 

 

 

 

使用后：

 

 

 

 

 

 

 

（3）jsr331-api-1.1.1.jar是必须的，利用CXF发布REST服务得用到它。

 

<beans xmlns="http://www.springframework.org/schema/beans"

 

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

 

    xmlns:jaxrs="http://cxf.apache.org/jaxrs"

 

    xmlns:jaxws="http://cxf.apache.org/jaxws"

 

    xsi:schemaLocation="

 

       http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd

 

       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd

 

       http://cxf.apache.org/core http://cxf.apache.org/schemas/core.xsd

 

       http://cxf.apache.org/jaxrs http://cxf.apache.org/schemas/jaxrs.xsd

 

       http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">

 

 

 

applicationXML.xml文件中加入如上链接，还是不行，报错：

 

cvc-complex-type.2.4.a: Invalid content was found starting with element 'jaxrs:extensionMappings'. One of '{"http://cxf.apache.org/jaxws":binding, "http://

 

 cxf.apache.org/jaxws":dataBinding, "http://cxf.apache.org/jaxws":executor, "http://cxf.apache.org/jaxws":features, "http://cxf.apache.org/jaxws":handlers, "http://

 

 cxf.apache.org/jaxws":inInterceptors, "http://cxf.apache.org/jaxws":inFaultInterceptors, "http://cxf.apache.org/jaxws":invoker, "http://cxf.apache.org/

 

 jaxws":outInterceptors, "http://cxf.apache.org/jaxws":outFaultInterceptors, "http://cxf.apache.org/jaxws":properties, "http://cxf.apache.org/jaxws":schemaLocations,

 

 "http://cxf.apache.org/jaxws":serviceFactory}' is expected.

（3）JAXB

 

JAXB可以相当灵活以支持其他格式，而不仅限于xml格式。

 

Jettison就是一个开源的JAXB适配器

 

参考：http://liugang594.iteye.com/blog/1499813

 

<FlowInfo settleFlowNo="0001">

 

<regOrg>zhongdeng</regOrg>

 

</FlowInfo>

 

 

 

（4）cxf把异常信息转换为JSON或者XML格式

 

参考：http://yufenfei.iteye.com/blog/1717098

 

 

 

第一步：编写自己的异常处理类 InvokeFaultExceptionMapper                     

 

@Provider

 

public class InvokeFaultExceptionMapper implements ExceptionMapper { 

 

 

 

   public Response toResponse(Throwable ex) { 

 

        StackTraceElement[] trace = new StackTraceElement[1]; 

 

           trace[0] = ex.getStackTrace()[0]; 

 

           ex.setStackTrace(trace); 

 

           ResponseBuilder rb = Response.status(Response.Status.INTERNAL_SERVER_ERROR); 

 

           rb.type("application/json;charset=UTF-8"); 

 

            rb.entity(ex); 

 

            rb.language(Locale.SIMPLIFIED_CHINESE); 

 

            Response r = rb.build(); 

 

            return r; 

 

    } 

 

 

 

}

 

 

 

第二部：加载InvokeFaultExceptionMapper

 

<jaxrs:server id="expGateway" address="/expGateway"> 

 

    <jaxrs:inInterceptors> 

 

       <ref bean="inMessageInterceptor"/> 

 

    </jaxrs:inInterceptors> 

 

    <jaxrs:outInterceptors> 

 

        <ref bean="outMessageInterceptor"/> 

 

    </jaxrs:outInterceptors> 

 

    <jaxrs:serviceBeans> 

 

        <ref bean="expGatewayImpl" /> 

 

    </jaxrs:serviceBeans> 

 

    <jaxrs:extensionMappings> 

 

        <entry key="json" value="application/json" /> 

 

        <entry key="xml" value="application/xml" /> 

 

    </jaxrs:extensionMappings> 

 

    <jaxrs:languageMappings> 

 

        <entry key="en" value="en-gb" /> 

 

    </jaxrs:languageMappings> 

 

    <jaxrs:providers> 

 

        <bean class="com.pml.service.outer.InvokeFaultExceptionMapper"/> 

 

    </jaxrs:providers> 

 

</jaxrs:server>

 

（5）创建一个基于WS-Security标准的安全验证(CXF回调函数使用,)
