REST保险实践·2.FORM认证

REST安全实践·2.FORM认证

2. DataSourceRealm + FORM认证

Accesses authentication information stored in a relational database, accessed via a named JNDI JDBC DataSource.通过JNDI访问关系型数据库，获取认证信息

2.1 创建Realm所需的数据表

mysql -uroot -p < security.sql

2.2 配置DataSourceRealm

$CATALINA_BASE/conf/server.xml 设置DATA SOURCE

<Resource auth="Container"driverClassName="org.gjt.mm.mysql.Driver"type="javax.sql.DataSource"name="jdbc/rest-security"username="root" password="root" url="jdbc:mysql://localhost:3306/simple_service_book"validationQuery="select 1 from users"/>

设置DataSourceRealm

<Realm className="org.apache.catalina.realm.DataSourceRealm"   dataSourceName="jdbc/rest-security"   userTable="users"   userNameCol="user_name"   userCredCol="user_pass"   userRoleTable="user_roles"   roleNameCol="role_name"/>

Eclipse内置Tomcat配置?

2.3 数据库驱动

拷贝Mysql的JDBC驱动到$CATALINA_HOME/lib目录。使用Maven的项目可以从本地仓库取得，否则从网上搜吧。

M2_REPO/mysql/mysql-connector-java/5.1.25/mysql-connector-java-5.1.25.jar (仓库地址举例：M2_REPO=C:\Users\hanl\.m2\repository)

2.4 配置应用的web.xml

/security-rest/src/main/webapp/WEB-INF/web.xml

<resource-ref>    <description>MySQL DB Connection Pool</description>    <res-ref-name>jdbc/rest-security</res-ref-name>    <res-type>javax.sql.DataSource</res-type>    <res-auth>Container</res-auth>    <res-sharing-scope>Shareable</res-sharing-scope></resource-ref><security-constraint>    <web-resource-collection>        <url-pattern>/*</url-pattern>        <http-method>GET</http-method>    </web-resource-collection>    <web-resource-collection>        <url-pattern>/webapi/*</url-pattern>        <http-method>GET</http-method>        <http-method>POST</http-method>        <http-method>UPDATE</http-method>        <http-method>DELETE</http-method>    </web-resource-collection>    <auth-constraint>        <role-name>admin</role-name>    </auth-constraint></security-constraint><security-constraint>    <web-resource-collection>        <url-pattern>/*</url-pattern>        <http-method>GET</http-method>    </web-resource-collection>    <web-resource-collection>        <url-pattern>/webapi/*</url-pattern>        <http-method>GET</http-method>    </web-resource-collection>    <auth-constraint>        <role-name>user</role-name>    </auth-constraint></security-constraint><login-config>    <auth-method>FORM</auth-method>    <form-login-config>        <form-login-page>/login.html</form-login-page>        <form-error-page>/error.html</form-error-page>    </form-login-config></login-config><welcome-file-list>    <welcome-file>/index.html</welcome-file></welcome-file-list>

2.5 登录页面

<form action="j_security_check">    <div>        <span>User Name</span>        <input id="j_username" name="j_username" type="text" />    </div>    <div style="margin-top:10px;margin-bottom:10px;">        <span>Pass Word</span>        <input id="j_password" name="j_password" type="password" />    </div>    <input type="submit" value="Sign In" /></form>

2.6 FORM认证

C:\Users\hanl.m2\repository\org\apache\tomcat\tomcat-catalina\7.0.42\tomcat-catalina-7.0.42-sources.jar

Realm.authenticate()?
