需要安全认证的远程EJB调用示例(Jboss EAP 6.2环境)

时间：2022-05-04 11:12:59

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"

        <version.ejb.plugin>2.3</version.ejb.plugin>

        <maven.compiler.target>1.6</maven.compiler.target>

        <maven.compiler.source>1.6</maven.compiler.source>

    </properties>

    <dependencyManagement>

        <dependencies>

            </dependency>

        </dependencies>

    </dependencyManagement>

    <dependencies>

        <dependency>

            <groupId>org.jboss.spec.javax.annotation</groupId>

            <artifactId>jboss-annotations-api_1.1_spec</artifactId>

            <scope>provided</scope>

        </dependency>

        <dependency>

            <groupId>org.jboss.spec.javax.ejb</groupId>

        </dependency>

    </dependencies>

    <build>

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

        <plugins>

            <plugin>

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

                <artifactId>jboss-as-maven-plugin</artifactId>

                <version>${version.jboss.maven.plugin}</version>

                <configuration>

                    <filename>${project.build.finalName}.jar</filename>

                </configuration>

                    <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)
