CXF WS-Policy配置

Question

我有以下CXF配置类：

package de.wps.ztr.config;

import org.apache.cxf.Bus;
import org.apache.cxf.bus.spring.SpringBus;
import org.apache.cxf.jaxws.EndpointImpl;
import org.apache.cxf.ws.policy.attachment.external.PolicyAttachment;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Profile;

import javax.xml.ws.Endpoint;

@Configuration
public class CxfConfig {

    @Bean(name = Bus.DEFAULT_BUS_ID)
    public SpringBus springBus() {
        final SpringBus springBus = new SpringBus();
        return springBus;
    }

    @Bean
    public MyService myService() {
        return new MyService();
    }

    @Bean
    public Endpoint myServiceEndpoint() {
        final EndpointImpl endpoint = new EndpointImpl(springBus(), MyService());

        endpoint.publish("...");

        return endpoint;
    }

}

它配置CXF总线并发布端点。我要为该终结点配置WS策略。该策略在外部文件中定义。下面解释了如何使用XML配置文件来实现这一点：

这是一个来自CXF站点的示例：

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:jaxws="http://cxf.apache.org/jaxws"
       xmlns:cxf="http://cxf.apache.org/core"
       xmlns:p="http://cxf.apache.org/policy"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="
http://cxf.apache.org/core http://cxf.apache.org/schemas/core.xsd
http://cxf.apache.org/policy http://cxf.apache.org/schemas/policy.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"
http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">
    <jaxws:endpoint id="CRMService"
            xmlns:serviceNamespace="http://services.talend.org/CRMService"
            serviceName="serviceNamespace:CRMServiceProvider"
            endpointName="serviceNamespace:CRMServicePort"
            implementor="#CRMServiceBean"
            address="/CRMServiceProvider">
            <jaxws:features>
                <p:policies>
                    <wsp:PolicyReference xmlns:wsp="http://www.w3.org/ns/ws-policy" URI="classpath:/saml.policy"/>
                </p:policies>
            </jaxws:features>
    </jaxws:endpoint>
</beans>

问题是，我如何使用API以编程方式做同样的事情？

Answer 1

从外部位置获取策略并为当前消息构建策略。

使用Neethi库解析WS-Policy XML。将结果策略对象存储到PolicyConstants.POLICY_OVERRIDE消息内容属性中。

重要的是，此自定义策略拦截器在CXF PolicyInInterceptor或PolicyOutInterceptor之前调用。则CXF将自动识别存储在此属性中的策略，并以最高优先级使用它。

您可以找到几个代码示例：http://www.programcreek.com/java-api-examples/index.php?source_dir=tesb-rt-se-master/policies/validation-policy/src/test/java/org/talend/esb/policy/schemavalidate/tests/policy/AbstractPolicyTest.java

Answer 2

在sei或实现类中使用@Policies或@Policy注释。在注释中指定策略的uri。参考http://cxf.apache.org/docs/annotations.html

import org.apache.cxf.annotations.Policies;
import org.apache.cxf.annotations.Policy;
      @WebService
        /*
         * Attaching Endpoint level Policy
         */
        @Policy(uri = "policy.xml" )   
        public interface HelloWorld {

            /**
             * Accepts username and greets with message
             * @param username
             * @return message 
             */
            /*
             * Attaching Policy using annotation for sending encrypted & signed body
             */
            @Policies({
                @Policy(uri = "methodPolicy.xml")
            }) 
            String sayHi(String username);

    }
