Tomcat 8.5 JDBC Realm 使用摘要加盐密码:身份验证失败

Question

我正在尝试使用摘要密码运行身份验证。不幸的是，身份验证失败并出现 401 错误。

在我的数据库usersdb中，有一个名为users的表，其中列user_name和user_pass。此外，还有一个桌子user_roles，上面有user_name和role_name。

我的用户称为syncuser，其角色users.sync。

我消化密码

digest.bat -a sha-512 -i 3 -s 8 -h org.apache.catalina.realm.MessageDigestCredentialHandler MySyncPassword
MySyncPassword:5800a4431c85d7a2$3$81a3cbfe53c94b128c1a37e5101cc7d5c5c69f4b4d4262113247a6db79bb5f8bcdcf57df8b2e1980d954be4ece50c40d862c866d3c44e2fc02cd6ecebcc4a830

我将整个字符串5800a4431c85d7a2$3$81a3cbfe53c94b128c1a37e5101cc7d5c5c69f4b4d4262113247a6db79bb5f8bcdcf57df8b2e1980d954be4ece50c40d862c866d3c44e2fc02cd6ecebcc4a830放入我的user_pass列中。

在网络底部.xml在我的项目中，我有

<login-config>
<auth-method>BASIC</auth-method>
</login-config>
<security-constraint>
<display-name>My Magical Project Security Constraint</display-name>
<web-resource-collection>
<web-resource-name>ServerBackend</web-resource-name>
<url-pattern>/SyncServlet</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>users.sync</role-name>
</auth-constraint>
</security-constraint>
<security-role>
<role-name>users.sync</role-name>
</security-role>
<security-role>
<role-name>*</role-name>
</security-role>
</web-app>

我已经通过MD5加密，1次迭代和0次盐以简单的方式尝试了所有这些。问题仍然存在。

事实证明，我的tomcat服务器上缺少JDBC驱动程序库。ClassNotFoundException 未显示在服务器控制台中。

此外，我将Realm标签中的connectionURL从connectionURL="jdbc:mysql://localhost:3306/usersdb?user=root&password=MySQL_Password"更改为

connectionURL="jdbc:mysql://localhost:3306/usersdb"
connectionName="root"
connectionPassword="MySQL_Password"
