Question

<Realm className="org.apache.catalina.realm.JDBCRealm"
       driverName="com.mysql.jdbc.Driver"
       connectionURL="jdbc:mysql://localhost/db"
       connectionName="user"
       connectionPassword="password"
       allRolesMode="authOnly"
       digest="SHA" 
       userTable="app" 
       userNameCol="login" 
       userCredCol="login"
       userRoleTable="login" 
       roleNameCol="group"/>  

<login-config>
    <auth-method>FORM</auth-method>
    <realm-name>realm</realm-name>
    <form-login-config>
        <form-login-page>/login.jsp</form-login-page>
        <form-error-page>/error.jsp</form-error-page>
    </form-login-config>
</login-config>

<form action="j_security_check" method="POST">
<tr>username:<td><input type="text"     name="j_username" style="width:100px;"></td></tr>
<tr> password:<td><input type="text"     name="j_ password " style="width:100px;"></td></tr>
<tr>< input type="submit"   name="btnLogin" value="login"></td></tr>
</form>

部署后，我收到HTTP状态400 - 对表单登录页面的无效直接引用

这是浏览器控制台输出..

另外我启用了log for realm，j_security_check在成功登录后没有重定向

FINE:  Not subject to any constraint

Answer 1

tomcat中的身份验证通过挑战来运行。如果您尝试访问受保护的资源，Tomcat会将您重定向到登录页面。经过身份验证后，它将重定向到请求的初始页面。如果直接访问登录页面，则没有初始请求，因此出现错误： HTTP Status 400 - Invalid direct reference to form login page

在您的情况下，要么首先尝试访问受保护资源，要么将landingPage属性添加到验证器以获得所需内容（see the documentation）

编辑：landingPage属性仅在Tomcat7之后可用。

例如，在context.xml文件中：

<Context>
<Valve className="org.apache.catalina.authenticator.FormAuthenticator" landingPage="connected.jsp"/>
<Realm className="org.apache.catalina.realm.JDBCRealm"
   driverName="com.mysql.jdbc.Driver"
   connectionURL="jdbc:mysql://localhost/db"
   connectionName="user"
   connectionPassword="password"
   allRolesMode="authOnly"
   digest="SHA" 
   userTable="app" 
   userNameCol="login" 
   userCredCol="login"
   userRoleTable="login" 
   roleNameCol="group"/>
</Context>

tomcat jdbc域 - j_security不重定向
