java - 使用 WildFly 进行自定义 Web 应用程序身份验证

标签 java wildfly-9 undertow

我需要为在 WildFly 9 服务器上运行的 Java EE 应用程序创建自定义 Web 应用程序身份验证。我在 the undertow website documentation 中找到了一些关于如何做的信息。 .

到目前为止，我所做的是创建一个io.undertow.servlet.ServletExtension 实现:

package mypackage;

import java.util.Map;
import javax.servlet.ServletContext;
import org.jboss.as.domain.http.server.security.AnonymousMechanism;
import io.undertow.security.api.AuthenticationMechanism;
import io.undertow.security.api.AuthenticationMechanismFactory;
import io.undertow.server.handlers.form.FormParserFactory;
import io.undertow.servlet.ServletExtension;
import io.undertow.servlet.api.DeploymentInfo;

public class MyServletExtension implements ServletExtension {

    @Override
    public void handleDeployment(DeploymentInfo deploymentInfo, ServletContext servletContext) {
        deploymentInfo.addAuthenticationMechanism("MY-AUTH", new AuthenticationMechanismFactory() {
            @Override
            public AuthenticationMechanism create(String mechanismName, FormParserFactory formParserFactory, Map<String, String> properties) {
                return new AnonymousMechanism();
            }
        });
    }
}

然后我在 src/main/resources/META-INF/services/中添加了一个名为 io.undertow.servlet.ServletExtension 的文件，内容为:mypackage.MyServletExtension。

最后，我修改了我的 web.xml 文件，如下所示:

<?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" version="3.1">

    <display-name>my-app</display-name>

    <security-constraint>
        <web-resource-collection>
            <web-resource-name>restricted resources</web-resource-name>
            <url-pattern>/*</url-pattern>
        </web-resource-collection>
        <auth-constraint>
            <role-name>*</role-name>
        </auth-constraint>
    </security-constraint>

    <security-role>
        <role-name>*</role-name>
    </security-role>

    <login-config>
        <auth-method>MY-AUTH</auth-method>
    </login-config>

</web-app>

在我的 pom.xml 文件中，我有这些依赖项:

<dependency>
    <groupId>io.undertow</groupId>
    <artifactId>undertow-core</artifactId>
    <version>1.2.9.Final</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>io.undertow</groupId>
    <artifactId>undertow-servlet</artifactId>
    <version>1.2.9.Final</version>
    <scope>provided</scope>
</dependency>

但是在服务器启动时我有这个错误:

09:40:20,192 ERROR [org.jboss.msc.service.fail] (ServerService Thread Pool -- 27) MSC000001: Failed to start service jboss.undertow.deployment.default-server.default-host./my-app-web: org.jboss.msc.service.StartException in service jboss.undertow.deployment.default-server.default-host./my-app-web: java.lang.LinkageError: Failed to link mypackage/MyServletExtension (Module "deployment.my-app-0.0.1-SNAPSHOT.ear.my-app-ejb.jar:main" from Service Module Loader)

当我将依赖范围从提供更改为编译时，出现另一个异常:

有人能告诉我我的配置有什么问题吗？

最佳答案

您已将它打包在默认情况下不依赖于 undertow 的 ejb-jar 中。

你需要添加

Dependencies: io.undertow.servlet io.undertow.core

到 META-INF/MANIFEST.MF(或使用 jboss-deployment-structure.xml 或将其打包到默认获取这些依赖项的 war 中)。
