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应用程序认证。我发现了有关如何在the undertow website documentation中完成的一些信息。使用WildFly自定义Web应用程序认证
我迄今所做的就是创建一个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();
}
});
}
}
于是我加了一个在SRC /主/资源/ META-INF /服务名为io.undertow.servlet.ServletExtension文件/内容：mypackage.MyServletExtension。
最后，我已经修改了我的web.xml文件是这样的：
<?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关系：
<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>
但在服务器启动时我有这样的错误：

当我改变依赖从提供的范围到编译，我有另一个除外离子：

有人能告诉我什么是我的配置有问题吗？
为什么不使用JASPIC？这就是Java EE API，并且得到了WildFly的很好的支持，并且有更好的文档记录。你现在正在做的是使用底层的内部API。 –
