匿名将默认应用程序上下文传递给远程EJB

匿名将默认应用程序上下文传递给远程EJB

在jboss / wildfly服务器上工作了几个月后，我终于找到了实现此功能的途径：

客户端代码：（基于jboss ejbclient）

package com.mycompany.view.service.wildfly.invocationcontext;import com.mycompany.ejb.internal.MyCompanyAccount;import com.mycompany.view.service.account.LoggedInAccount;import java.util.logging.Level;import java.util.logging.Logger;import javax.annotation.PostConstruct;import javax.ejb.Singleton;import javax.ejb.Startup;import javax.enterprise.inject.Instance;import javax.inject.Inject;import org.jboss.ejb.client.AttachmentKey;import org.jboss.ejb.client.EJBClientContext;import org.jboss.ejb.client.EJBClientInterceptor;import org.jboss.ejb.client.EJBClientInvocationContext;import static com.mycompany.management.wildfly.invocationcontext.MyCompanyInvocationContextKey.MYCOMPANY_ACCOUNT_NUMBER;@Singleton@Startuppublic class MyCompanyInvocationContextInterceptor implements EJBClientInterceptor {    private static final Logger LOG = Logger.getLogger(MyCompanyInvocationContextInterceptor.class.getName());    private static final AttachmentKey<Long> MYCOMPANY_ACCOUNT_NUMBER_KEY = new AttachmentKey<>();    @Inject    @LoggedInAccount    private Instance<MyCompanyAccount> loggedInAccount;    @PostConstruct    void registerSelf() {        EJBClientContext.requireCurrent().registerInterceptor(0, this);    }    @Override    public void handleInvocation(final EJBClientInvocationContext ejbcic) throws Exception {        LOG.log(Level.INFO, "Intercepting invocation on: {0}", ejbcic.getInvokedMethod());        final EJBClientContext clientContext = ejbcic.getClientContext();        if (!loggedInAccount.isUnsatisfied()) { final MyCompanyAccount mycompanyAccount = loggedInAccount.get(); if (mycompanyAccount != null) {     final Long accountNumber = mycompanyAccount.getAccountNumber();     clientContext.putAttachment(MYCOMPANY_ACCOUNT_NUMBER_KEY, accountNumber); }        }        ejbcic.getContextData().put(MYCOMPANY_ACCOUNT_NUMBER, "348347878483");        ejbcic.sendRequest();    }    @Override    public Object handleInvocationResult(final EJBClientInvocationContext ejbcic) throws Exception {        return ejbcic.getResult();    }}

在服务器端，我注册了一个全局拦截器：

package com.mycompany.management.wildfly.extension;import com.mycompany.management.facade.account.MyCompanyAccountFacade;import java.util.Map;import java.util.logging.Level;import java.util.logging.Logger;import javax.annotation.Resource;import javax.ejb.EJB;import javax.ejb.EJBContext;import javax.interceptor.AroundInvoke;import javax.interceptor.InvocationContext;public class MyCompanyInvocationContextReceiver {    private static final Logger LOG = Logger.getLogger(MyCompanyInvocationContextReceiver.class.getName());    @Resource    private EJBContext ejbContext;    @EJB    private MyCompanyInvocationContext mycompanyInvocationContext;    @EJB    private MyCompanyAccountFacade mycompanyAccountFacade;    @AroundInvoke    public Object setMyCompanyAccount(final InvocationContext invocationContext) throws Exception {        final Map<String, Object> contextData = ejbContext.getContextData();        LOG.log(Level.INFO, "EJBContext data: {0}", contextData);        LOG.log(Level.INFO, "InvocationContext data: {0}", invocationContext.getContextData());        return invocationContext.proceed();    }}

和ejb-jar.xml：

<?xml version="1.0" encoding="UTF-8"?><ejb-jar xmlns = "http://java.sun.com/xml/ns/javaee"         version = "3.1"         xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"         xsi:schemaLocation = "http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/ejb-jar_3_1.xsd">    <interceptors>        <interceptor> <interceptor-class>com.mycompany.management.wildfly.extension.MyCompanyInvocationContextReceiver</interceptor-class>        </interceptor>    </interceptors>    <assembly-descriptor>        <interceptor-binding> <ejb-name>*</ejb-name> <interceptor-class>com.mycompany.management.wildfly.extension.MyCompanyInvocationContextReceiver</interceptor-class>        </interceptor-binding>    </assembly-descriptor></ejb-jar>

如服务器端拦截器上所示，您可以从InvocationContext或EJBContext获得客户端发送的数据。
