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找到了很少有关如何操作的信息。
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:
<?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:

有人可以告诉我配置有什么问题吗?
答案 0 :(得分:1)
您已将其打包在一个ejb-jar中,默认情况下它不会依赖于下载。
您需要添加
Dependencies: io.undertow.servlet io.undertow.core
到META-INF / MANIFEST.MF(或使用jboss-deployment-structure.xml或将其打包在默认情况下获取这些依赖关系的war中。)
