【问题描述】：

我将一个项目从 Java EE 6 迁移到 Java EE 7。作为依赖项，我有 javaee 7.0，payara-embedded-all4.1.1.154
我将 beans.xml 迁移到：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd"
    bean-discovery-mode="all">
    <interceptors>
        <class>com.myproject.business.base.util.LoggingInterceptor</class>
    </interceptors>
</beans>

还有 web.xml 到：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee 
         http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
    id="WebApp_ID" version="3.1">
    <display-name>com.myproject.business.server</display-name>
    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.htm</welcome-file>
        <welcome-file>index.jsp</welcome-file>
        <welcome-file>default.html</welcome-file>
        <welcome-file>default.htm</welcome-file>
        <welcome-file>default.jsp</welcome-file>
    </welcome-file-list>

    <login-config>
        <auth-method>BASIC</auth-method>
        <realm-name>myprojectRealm</realm-name>
    </login-config>

    <security-constraint>
        <display-name>Basic Protection</display-name>
        <web-resource-collection>
            <web-resource-name>REST</web-resource-name>
            <description />
            <url-pattern>/myproject/*</url-pattern>
            <http-method>GET</http-method>
            <http-method>POST</http-method>
            <http-method>PUT</http-method>
            <http-method>DELETE</http-method>
        </web-resource-collection>
        <auth-constraint>
            <description />
            <role-name>com.myproject.ftc.Reader</role-name>
            <role-name>com.myproject.um.Administrator</role-name>
            <role-name>com.myproject.ftc.Skriptimporteur</role-name>
            <role-name>com.myproject.operations.Admin</role-name>
        </auth-constraint>
    </security-constraint>
    <security-role>
        <role-name>com.myproject.ftc.Reader</role-name>
    </security-role>
    <security-role>
        <role-name>com.myproject.ftc.Exporter</role-name>
    </security-role>
    <security-role>
        <role-name>com.myproject.operations.Admin</role-name>
    </security-role>

</web-app>

并且将 sun-web.xml 替换为 glassfish-web.xml：

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE glassfish-web-app PUBLIC "-//GlassFish.org//DTD GlassFish Application Server 3.1 Servlet 3.0//EN" "http://glassfish.org/dtds/glassfish-web-app_3_0-1.dtd">
<glassfish-web-app>
    <context-root>/com.myproject.business.server</context-root>
</glassfish-web-app>

一切都是可编译的，但是当我想将应用程序部署到 payara 时遇到问题：

同样奇怪的是它给了我EJB31_Generated，我添加了一个3.2版的maven-ejb-plugin并拥有Payara 4.1.1.154。

有人知道为什么吗？

【问题讨论】：

它为您提供 EJB31_Generated 因为您可能在 ejb-jar.xml 文件中引用了 EJB 3.1。你有@Startup豆子吗？
我没有 ejb-jar.xml。我读过（JEE7 教程第 16.12 章）是可选的。我没有@Startup bean。我使用 maven-ejb-plugin 指定 ejb 版本
您对 EJB 做了哪些更改？
没有变化，只是用 javaee 7 替换 javaee 6，用 payara-embedded-all 替换 glassfish-embedded-all 3.x 并替换一些从类中导入的情况。
我解决了。即将注册一些资源（抱歉不能很好地格式化它）：@ApplicationPath("project") public class RESTConfig extends Application { @Override public Set> getClasses() { final Set > 资源 = 新的 HashSet>(); // 添加你的资源。资源.add(AdminConsoleResource.class); // 添加附加功能，例如对 Multipart 的支持。资源.add(MultiPartFeature.class);返还资源； } }

【解决方案1】：

我解决了。即将注册一些资源：

@ApplicationPath("project") 
public class RESTConfig extends Application { 

  @Override public Set<Class<?>> getClasses() { 
    final Set<Class<?>> resources = new HashSet<Class<?>>(); // Add your resources. 

    resources.add(AdminConsoleResource.class); // Add additional features such as support for Multipart. 

    resources.add(MultiPartFeature.class); 

    return resources; 
  } 
}
