以下是所有相关文件.我有一个MysqL数据库,其中包含使用以下模式定义的用户和角色：

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>

这是我的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,这是jboss-web.xml：

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

我还应该补充一点,我使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,2);

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

如您所见,所有三个用户(例如user1,user2,user3)都具有相同的密码;但在每种情况下,使用MD5哈希编码(或不编码)密码.但是,上述情况都不起作用.这是我认为的问题的核心.
