java - 在 JBoss 7.1 上部署 EJB

Question

我正在部署一个非常简单的 helloworld 风格的 EJB 应用程序。这样做时我得到...

看起来我需要在某处添加一个包含，我的代码很简单......

package server;

import java.io.IOException;
import java.io.PrintWriter;

import javax.ejb.EJB;
import javax.persistence.EntityManagerFactory;
import javax.persistence.PersistenceUnit;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import model.MyUser;

/**
 * Servlet implementation class HelloServlet
 */
@WebServlet("/HelloServlet")
public class HelloServlet extends HttpServlet {
    private static final long serialVersionUID = 1L;


    @EJB HelloBean bean;
    @PersistenceUnit
    EntityManagerFactory emF;
    /**
     * @see HttpServlet#HttpServlet()
     */
    public HelloServlet() {
        super();
        // TODO Auto-generated constructor stub
    }

    /**
     * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        PrintWriter out = response.getWriter();
        out.print("<html><body>");
        MyUser user = (MyUser)emF.createEntityManager().createQuery("select * from  myuser").getResultList().get(0);
        out.println("Username = " + user.getName());
        out.print("</body></html>");
    }

    /**
     * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub
    }

}

Persistance.xml如下所示...

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
    <persistence-unit name="HelloWorld">
        <jta-data-source>EjbMySql</jta-data-source>
        <class>model.MyUser</class>
    </persistence-unit>
</persistence>

modules/com/mysql/main/Modules.xml如下...

<module xmlns="urn:jboss:module:1.0" name="com.mysql.jdbc">
  <resources>
    <resource-root path="mysql-connector-java-5.1.18-bin.jar"/>
  </resources>
  <dependencies>
    <module name="javax.api"/>
  </dependencies>
</module>

Standalone.xml 具有以下条目...

<subsystem xmlns="urn:jboss:domain:datasources:1.0">
           <datasources>
            <datasource jndi-name="java:jboss/datasources/EjbMySql" pool-name="EjbMySql" enabled="true" use-java-context="true">
                <connection-url>jdbc:mysql://localhost:3306/ejbdb</connection-url>
                <driver>com.mysql</driver>
                <security>
                    <user-name>root</user-name>

            <driver name="com.mysql" module="com.mysql.jdbc"> <xa-datasource-class>com.mysql.jdbc.Driver</xa-datasource-class> </driver>
        </drivers>
        </datasources>
        </subsystem>

在我的项目中，我在/WebContent/META-INF/services/mysql-connector-java-5.1.18-bin.jar 中有 MySQL jar

有没有人有什么想法？

谢谢!

编辑:试过...

<datasource jndi-name="java:jboss/datasources/EjbMySql" pool-name="EjbMySql" enabled="true" use-java-context="true">
                    <connection-url>jdbc:mysql://localhost:3306/ejbdb</connection-url>
                    <driver>com.mysql.jdbc.Driver</driver>
                    <security>
                        <user-name>root</user-name>
                        <password>root</password>
                    </security>

返回同样的错误。

Answer 1

在<JBOSS_HOME>/standalone/configuration/standalone.xml找到 <subsystem xmlns="urn:jboss:domain:datasources:1.0">标记并在 <datasources> 中添加以下内容元素:

<datasources>
    <datasource jndi-name="java:jboss/datasources/MysqlDS" pool-name="MysqlDS" enabled="true" use-java-context="true">
        <connection-url>jdbc:mysql://localhost:3306/DATABASE_NAME</connection-url>
        <driver>com.mysql</driver>
        <security>
            <user-name>USERNAME</user-name>
            <password>PASSWORD</password>
        </security>
    </datasource>
    <drivers>
        <driver name="com.mysql" module="com.mysql">
            <xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>
        </driver>
    </drivers>
</datasources>

适本地替换 DATABASE_NAME、USERNAME 和 PASSWORD。

在<drivers>里面元素添加以下内容:

<driver name="com.mysql" module="com.mysql">
    <xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>
</driver>

现在，转到 <JBOSS_HOME>/modules并创建路径 com/mysql/main将驱动程序的 jar 放在那里(例如 mysql-connector-java-5.1.18-bin.jar)并创建文件 module.xml内容如下:

<module xmlns="urn:jboss:module:1.1" name="com.mysql">

    <resources>
        <resource-root path="mysql-connector-java-5.1.18-bin.jar"/>
        <!-- Insert resources here -->
    </resources>
    <dependencies>
        <module name="javax.api"/>
        <module name="javax.transaction.api"/>
        <module name="javax.servlet.api" optional="true"/>
    </dependencies>
</module>

这应该可以解决问题。
