如何在Web应用程序中为摘要式身份验证配置JBoss DatabaseServerLoginModule

在一句话中,我想将JBoss4.2.2配置为使用databaseServerLoginModule作为通过摘要式身份验证安全的Web应用程序的登录模块。我的问题是密码验证失败。我怀疑问题在于我如何定义应用程序策略,或者密码是如何存储在数据库中的。

以下是所有相关文件。我有一个mysql数据库,其中用户和角色使用以下模式定义:

CREATE TABLE SR_USER (
  ID BIGINT(19) NOT NULL AUTO_INCREMENT,
  USERNAME VARCHAR(20) NOT NULL,
  PASSWORD VARCHAR(255) NOT NULL,
  PRIMARY KEY (ID)
)
CHARACTER SET utf8;

CREATE TABLE SR_ROLE (
  ID BIGINT(19) NOT NULL AUTO_INCREMENT,
  ROLE_NAME VARCHAR(20) NOT NULL,
  PRIMARY KEY (ID)
)
CHARACTER SET utf8;

CREATE TABLE SR_USER_ROLE (
  FK_USER_ID BIGINT(19) NOT NULL,
  FK_ROLE_ID BIGINT(19) NOT NULL,
  FOREIGN KEY (FK_USER_ID) REFERENCES SR_USER (ID),
  FOREIGN KEY (FK_ROLE_ID) REFERENCES SR_ROLE (ID)
)
CHARACTER SET utf8;

对于login-config.xml文件中的应用程序策略,我定义了以下内容:

<application-policy name="secrest">
    <authentication>
        <login-module code="org.jboss.security.auth.spi.DatabaseServerLoginModule"
            flag="required">
            <module-option name="dsJndiName">java:/SecRestDS</module-option>
            <module-option name="principalsQuery">
                SELECT PASSWORD FROM SR_USER WHERE USERNAME=?
                </module-option>
            <module-option name="rolesQuery">
                SELECT r.ROLE_NAME FROM SR_ROLE r, SR_USER_ROLE ur, SR_USER u WHERE
                u.USERNAME=? AND u.ID=ur.FK_USER_ID AND ur.FK_ROLE_ID=r.ID 
                </module-option>
            <module-option name="hashAlgorithm">MD5</module-option>
            <module-option name="hashEncoding">hex</module-option>
        </login-module>
    </authentication>
</application-policy>

以下是我的Web应用程序的web.xml文件:

<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    version="2.5">

    <servlet>
        <servlet-name>JerseyServlet</servlet-name>
        <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
        <init-param>
            <param-name>javax.ws.rs.Application</param-name>
            <param-value>com.acme.samples.SecureRESTApplication</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>JerseyServlet</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>

    <security-constraint>
        <web-resource-collection>
            <web-resource-name>secrest</web-resource-name>
            <url-pattern>/*</url-pattern>
        </web-resource-collection>
        <auth-constraint>
            <role-name>admin</role-name>
        </auth-constraint>
    </security-constraint>

    <login-config>
        <auth-method>DIGEST</auth-method>
    </login-config>
    <security-role>
        <role-name>admin</role-name>
    </security-role>

</web-app>

最后,这里是jboss-web.xml:

<jboss-web>
 <security-domain>java:/jaas/secrest</security-domain>
</jboss-web>

我还应该补充一下,我用以下内容填充数据库:

INSERT INTO SR_ROLE (ROLE_NAME) VALUES ('admin');
INSERT INTO SR_ROLE (ROLE_NAME) VALUES ('apiuser');

INSERT INTO SR_USER (USERNAME, PASSWORD) VALUES ('user1', PASSWORD('p455w0rd'));
INSERT INTO SR_USER (USERNAME, PASSWORD) VALUES ('user2', 'p455w0rd');
INSERT INTO SR_USER (USERNAME, PASSWORD) VALUES ('user3', 'a4fd8e6fa9fbf9a6f2c99e7b70aa9ef2');

INSERT INTO SR_USER_ROLE (FK_USER_ID, FK_ROLE_ID) VALUES (1, 1);
INSERT INTO SR_USER_ROLE (FK_USER_ID, FK_ROLE_ID) VALUES (1, 2);

INSERT INTO SR_USER_ROLE (FK_USER_ID, FK_ROLE_ID) VALUES (2, 1);
INSERT INTO SR_USER_ROLE (FK_USER_ID, FK_ROLE_ID) VALUES (2, 2);

INSERT INTO SR_USER_ROLE (FK_USER_ID, FK_ROLE_ID) VALUES (3, 1);
INSERT INTO SR_USER_ROLE (FK_USER_ID, FK_ROLE_ID) VALUES (3, 2);

如上所示,所有三个用户(如user1、user2、user3)都具有相同的密码;但在每种情况下,密码都使用MD5哈希进行编码(或不进行编码)。然而,以上这些都不起作用。我认为这是问题的核心。
