需要安全认证的远程EJB调用示例(Jboss EAP 6.2环境)

一，Remote EJB

服务接口定义:

package yjmyzz.ejb.server.helloworld;

public interface HelloWorldService {
    
    public String sayHello(String name);

}

实现:

package yjmyzz.ejb.server.helloworld;

import javax.annotation.security.RolesAllowed;
import javax.ejb.Remote;
import javax.ejb.Stateless;

@Stateless
@Remote(HelloWorldService.class)
@RolesAllowed({ "guest" })
public class HelloWorldBean implements HelloWorldService {

    public String sayHello(String name) {
        return "hello , " + name + " , welcome to EJB's world!";
    }

}

注意: @RoleAllowed({"guest"}) 该注解表示只有guest这个角色的用户才能调用HelloWorldBean

对应maven的pom.xml内容如下:

<?xml version="1.0"?>

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        </dependencies>
    </dependencyManagement>

    <dependencies>

        <dependency>
            <groupId>org.jboss.spec.javax.annotation</groupId>
            <artifactId>jboss-annotations-api_1.1_spec</artifactId>
            <scope>provided</scope>
        </dependency>

        <dependency>

    </dependencies>

    <build>

        <finalName>${project.artifactId}</finalName>
        <plugins>

            <plugin>
                <groupId>org.jboss.as.plugins</groupId>

                    <generateClient>true</generateClient>
                </configuration>
            </plugin>

        </plugins>
    </build>

</project>

二，EJB Client

package yjmyzz.ejb.client.helloworld;

import java.util.Hashtable;

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;

import yjmyzz.ejb.server.helloworld.HelloWorldService;


public class EjbClientApp {
    public static void main(String[] args) throws NamingException {
        System.out.println(lookupRemoteBean().sayHello("jimmy"));
    }

    @SuppressWarnings("unchecked")
    private static HelloWorldService lookupRemoteBean() throws NamingException {
        @SuppressWarnings("rawtypes")
        final Hashtable jndiProperties = new Hashtable();
        jndiProperties.put(Context.URL_PKG_PREFIXES,
                "org.jboss.ejb.client.naming");
        final Context context = new InitialContext(jndiProperties);
        return (HelloWorldService) context
                .lookup("ejb:/ejb-server-helloworld/HelloWorldBean!"
                        + HelloWorldService.class.getName());
    }
}

 注: lookupRemoteBean用于查找远程EJB.

jboss环境中,需要在classpath路径下放置jboss-ejb-client.properties文件,内容参考下面:

remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false
remote.connections=default
remote.connection.default.host=localhost
remote.connection.default.port = 4447
remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false
remote.connection.default.username=msgUser
remote.connection.default.password=Password1!

注: msgUser为jboss中创建的一个application user,而且属于guest组(不熟悉jboss下创建用户的朋友,可参考JMS + jboss EAP 6.2 示例 中的相关内容)

对应maven项目的pom.xml为:

    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
