将Spring Boot从1.3.7升级到1.4.0导致AuthenticatorBase.getJaspicProvider中的NullPointerException [英] Upgrading Spring Boot from 1.3.7 to 1.4.0 causing NullPointerException in AuthenticatorBase.getJaspicProvider
本文介绍了将Spring Boot从1.3.7升级到1.4.0导致AuthenticatorBase.getJaspicProvider中的NullPointerException的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
这在某种程度上是由spring-boot-starter-jersey随附的tomcat-embed-core版本8.5.4引起的.在所有集成测试中，它都会产生如下所示的错误.仅当我重写pom以使用tomcat-embed-core版本8.0.36时，它将起作用.奇怪的是，这是我收到的唯一错误消息.
This is somewhat caused by the tomcat-embed-core version 8.5.4 that comes with the spring-boot-starter-jersey. It generates an error shown below on all integration tests. It will only work if I override the pom to use tomcat-embed-core version 8.0.36. What's weird is, that's the only error message I get.
java.lang.NullPointerException: null

*/
@Autowired

public static void main(String[] args) throws Exception {
SpringApplication application = new SpringApplication(Application.class);
application.setBanner(new SampleBanner());

/**

*/
@Override

return (e, method, params) -> log.error("Uncaught async error", e);
}
}
如果有人可以指出我从哪里开始或导致它失败的原因，那将有很大的帮助.
If someone could point me out where to start or what's causing it to fail, it would be of great help.
推荐答案
可能的修复:
1)将authConfigFactory设置为Tomcat 8.5使用的默认AuthConfigFactory实现(示例基本实现):
1) Set authConfigFactory to default AuthConfigFactory implementation used by Tomcat 8.5 (example basic implementation):
package com.example;
import org.apache.catalina.authenticator.jaspic.AuthConfigFactoryImpl;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import javax.security.auth.message.config.AuthConfigFactory;
@SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
if (AuthConfigFactory.getFactory() == null) {
AuthConfigFactory.setFactory(new AuthConfigFactoryImpl());
}
SpringApplication.run(DemoApplication.class, args);
}
}
或
2)从类路径中删除重复的AuthConfigFactory类.就我而言，同一类有两种不同的实现:
2) Remove duplicated AuthConfigFactory class from your classpath. In my case there were two different implementations of the same class:
org.apache.tomcat.embed/tomcat-embed-core/8.5.4/tomcat-embed-core-8.5.4.jar!/javax/security/auth/message/config/AuthConfigFactory.class
javax/javaee-api/7.0/javaee-api-7.0.jar!/javax/security/auth/message/config/AuthConfigFactory.class
javaee-api-7.0.jar具有它自己的AuthConfigFactory实现，该实现与Tomcat 8.5不完全兼容，并导致NullPointerException(在Tomcat的版本中，有一个常量定义了默认的jaspic实现类)
从gradle/mvn项目中删除javaee-api依赖项(或任何其他包含不同AuthConfigFactory实现的依赖项)(如果可以)
javaee-api-7.0.jar has it's own AuthConfigFactory implementation which is not fully compatible with Tomcat 8.5 and causes that NullPointerException (in Tomcat's version there is constant which defines default jaspic implementation class)
Remove javaee-api dependency (or any other which contains different AuthConfigFactory implementation) from your gradle/mvn project (if you can)
或
3)将Tomcat降级到8.0或7.0:
3) Downgrade Tomcat to 8.0 or 7.0:
http://docs.spring. io/spring-boot/docs/current-SNAPSHOT/reference/htmlsingle/#howto-use-tomcat-7
说明:
问题与从Spring Boot从1.3.x升级到1.4期间进行的Tomcat升级(从8.0.x到8.5.x)有关. 问题是Tomcat 8.5引入了jaspic支持( https://tomcat.apache.org/tomcat- 8.5-doc/config/jaspic.html )，并提供了自己的AuthConfigFactory实现.此实现定义了默认的jaspic auth工厂实现:
The problem is related with Tomcat upgrade (from 8.0.x to 8.5.x) which has been made during Spring Boot upgrade from 1.3.x to 1.4. The problem is that Tomcat 8.5 introduces jaspic support (https://tomcat.apache.org/tomcat-8.5-doc/config/jaspic.html) and provides it's own implementation of AuthConfigFactory. This implementation defines default jaspic auth factory implementation:
private static final String DEFAULT_JASPI_AUTHCONFIGFACTORYIMPL =
"org.apache.catalina.authenticator.jaspic.AuthConfigFactoryImpl";
在其他实现中未定义(例如，来自javaee-api-7.0的实现)，并导致NullPointerException，因为未实例化AuthConfigFactory.
which is not defined in other implementations (e.g. that one from javaee-api-7.0) and causes NullPointerException because no AuthConfigFactory were instantiated.
这篇关于将Spring Boot从1.3.7升级到1.4.0导致AuthenticatorBase.getJaspicProvider中的NullPointerException的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
