java - Tomcat 8.5 JDBC Realm 与摘要加盐密码：身份验证失败

问题描述

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 的表，其中包含和users列。此外，还有一个带有和的表。user_nameuser_passuser_rolesuser_namerole_name

我的用户被调用syncuser，它具有角色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专栏。

在我项目中 web.xml 的底部，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>

我已经用 MD5 加密、1 次迭代和 0 盐以简单的方式尝试了这一切。问题仍然存在。

解决方案

原来，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connectionURL标签中的Realm从更改connectionURL="jdbc:mysql://localhost:3306/usersdb?user=root&amp;password=MySQL_Password"为

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