我正在尝试为我的servlet创建JAAS身份验证(在Eclipse中使用tomcat 8.5)。尝试登录时,出现以下错误。
StackTrace:

ProjectName:UserAndPasswordPrinciple
在server.xml中
<Realm className="com.princi.jaas.newJAASRealm"
appName="UserAndPasswordPrincipal"
userClassNames="com.princi.jaas.UserPrincipal"
roleClassNames="com.princi.jaas.RolePrincipal" ></Realm>
在%calatina%/ conf / jaas.config中
UserAndPasswordPrincipal {
com.princi.jaas.MyLoginModule required debug=true;
};
我在哪里给jaas.config文件位置感到困惑,所以我在这两个位置都给出了
java.security和startup.bat
在C:\ Program Files \ Java \ jdk1.8.0_201 \ jre \ lib \ security \ java.security
JAVA_OPTS=$JAVA_OPTS -Djava.security.auth.login.config=$CATALINA_BASE/conf/jaas.config
在startup.bat
.....
:okHome
set JAVA_OPTS=%JAVA_OPTS% -Djava.security.auth.login.config=%CATALINA_HOME%\conf\jaas.config
创建了一个jar文件并上传了我的课程
CatalinaHome / lib / MyLoginModule.jar包含
newJAASRealm extends JAASRealm

仅重写JAASRealm即可检查其是否正常
newJAASRealm.java
package com.princi.jaas;
import org.apache.catalina.realm.JAASRealm;
public class newJAASRealm extends JAASRealm{
}
