J2EE中web.xml的常用配置

列了J2EE中的一些xml配置，當(dāng)然并不全。
---------------------------------------------------------------------------------------------------------------------------------
配置servlet映射關(guān)系：

<web-app>
?? ......
?? <servlet>
??? ??? <servlet-name>ServletName</servlet-name>
??? ??? <servlet-class>com.jj.ServletClass</servlet-class>
??? ??? 
??? ??? <init-param>
??? ??? ??? <param-name>parameterName</param-name>
??? ??? ??? <param-value>parameterValue</param-value>
??? ??? </init-param>
??? </servlet>

??? <servlet-mapping>
??? ??? <servlet-name>ServletName</servlet-name>
??? ??? <url-pattern>/*.do</url-pattern>
??? </servlet-mapping>
??? ......
</web-app>
---------------------------------------------------------------------------------------------------------------------------------
配置監(jiān)聽器：

<web-app>
??? ........
??? <listener>
??? ??? <listener-class>com.jj.MyServletContextListener</listener-class>
??? </listener>
??? ........
</web-app>
---------------------------------------------------------------------------------------------------------------------------------
設(shè)置session超時(shí)：

<web-app>
??? ........
??? <session-config>
??? ??? 
??? ??? <session-timeout>15</session-timeout>
??? </session-config>
??? ........
</web-app>
---------------------------------------------------------------------------------------------------------------------------------
配置應(yīng)用上下文參數(shù)：

<web-app>
??? ........
???? <context-param>
??? ??? <param-name>parameterName</param-name>
??? ??? <param-value>parameterValue</param-value>
??? </context-param>
??? ........
</web-app>
---------------------------------------------------------------------------------------------------------------------------------
禁用scriptlet：

<web-app>
??? ........
??? <jsp-config>
??? ??? <jsp-property-group>
??? ??? ??? <url-pattern>*.jsp</url-pattern>
??? ??? ??? <scripting-invalid>true</scripting-invalid>
??? ??? </jsp-property-group>
??? </jsp-config>
??? ........
</web-app>
---------------------------------------------------------------------------------------------------------------------------------
忽略EL表達(dá)式語言：

<web-app>
??? ........
??? <jsp-config>
??? ??? <jsp-property-group>
??? ??? ??? <url-pattern>*.jsp</url-pattern>
??? ??? ??? <el-ignored>true</el-ignored>
??? ??? </jsp-property-group>
??? </jsp-config>
??? ........
</web-app>
---------------------------------------------------------------------------------------------------------------------------------
EL函數(shù)配置：

TLD(標(biāo)記庫描述文件)：
<taglib>
??? <uri>DiceFunctions</uri>
??? <function>
??? ??? <name>rollIt</name>
??? ??? <function-class>foo.DiceRoller</function-class>
??? ??? <function-signature>
??? ??? ??? int rollDice()
??? ??? </function-signature>
??? </function>
</taglib>

有函數(shù)的類：
package foo;
public class DiceRoller{
??? public static int rollerDice(){
??? ?? return (int)((Math.random()*6)+1);
??? }
}

JSP中調(diào)用
<%@ tiglib prefix="mine" uri="DiceFunctions" %>

<html><body>

${mine:rollIt()}

</body></html>
---------------------------------------------------------------------------------------------------------------------------------
定制錯(cuò)誤頁面：

根據(jù)異常類型定制錯(cuò)誤頁面：
<web-app>
??? ......
??? <error-page>
??? ??? <exception-type>java.lang.Throwable</exception-type>
??? ??? <location>/error.jsp</location>
??? </error-page>
??? ......
</web-app>

根據(jù)HTTP狀態(tài)碼定制錯(cuò)誤頁面：
<web-app>
??? ......
??? <error-page>
??? ??? <error-code>404</error-code>
??? ??? <location>/error.jsp</location>
??? </error-page>
??? ......
</web-app>
---------------------------------------------------------------------------------------------------------------------------------
定制標(biāo)記：

tld：
<taglib>
??? ......
??? <tag>
??? ??? <name>loop</name>
??? ??? <tag-class>com.pandajj.tag.LoopTag</tag-class>
??? ??? 
??? ??? <body-content>JSP</body-content>
??? ??? <attribute>
??? ??? ??? <name>times</name>
??? ??? ??? <required>true</required>
??? ??? ??? <rtexpralue>true</rtexpralue>
??? ??? </attribute>
??? </tag>
??? ......
</taglib>
---------------------------------------------------------------------------------------------------------------------------------
定制歡迎頁面：

<web-app>
??? ......
??? <welcome-file-list>
??? ??? <welcome-file>hello.html</welcome-file>
??? </welcome-file-list>
??? ......
</web-app>
---------------------------------------------------------------------------------------------------------------------------------
EJB相關(guān)和MIME映射：

<web-app>
??? ......
??? 
??? <ejb-local-ref>
??? ??? <ejb-ref-name>ejb/customer</ejb-ref-name>
??? ??? <ejb-ref-type>Entity</ejb-ref-type>
??? ??? <local-home>com.jj.CustomerHome</local-home>
??? ??? <local>com.jj.Customer</local>
??? </ejb-local-ref>
???
??? 
??? <ejb-ref>
??? ??? <ejb-ref-name>ejb/LocalCustomer</ejb-ref-name>
??? ??? <ejb-ref-type>Entity</ejb-ref-type>
??? ??? <home>com.jj.CustomerHome</home>
??? ??? <remote>com.jj.Customer</remote>
??? </ejb-ref>
???
??? 
??? <env-entry>
??? ??? <env-entry-name>rates/discountRate</env-entry-name>
??? ??? <env-entry-type>java.lang.Integer</env-entry-type>
??? ??? <env-entry-value>10</env-entry-value>
??? </env-entry>
???
??? 
??? <mime-mapping>
??? ??? <extension>mpg</extension>
??? ??? <mime-type>video/mpeg</mime-type>
??? </mime-mapping>
??? ......
</web-app>
---------------------------------------------------------------------------------------------------------------------------------
過濾器映射：

<web-app>
??? ......
??? <filter>
??? ??? <filter-name>FilterName</filter-name>
??? ??? <filter-class>com.jj.FilterClass</filter-class>
??? ??? <init-param>
??? ??? ??? <param-name>parameterName</param-name>
??? ??? ??? <param-value>parameterValue</param-value>
??? ??? </init-param>
??? </filter>
???
??? 
??? <filter-mapping>
??? ??? <filter-name>FilterName</filter-name>
??? ??? <url-pattern>*.do</url-pattern>
??? </filter-mapping>
???
??? 
??? <filter-mapping>
??? ??? <filter-name>FilterName</filter-name>
??? ??? <servlet-name>ServletName</servlet-name>
??? </filter-mapping>
??? ......
</web-app>
---------------------------------------------------------------------------------------------------------------------------------
授權(quán)：

<web-app>
??? ......
??? <security-role>
??? ??? 
??? ??? <role-name>admin</role-name>
??? </security-role>

??? <login-config>
??? ??? 
??? ??? <auth-method>BASIC</auth-method>
??? </login-config>

??? <security-constraint>
??? ??? <web-resource-collection>
??? ??? ??? <web-resource-name>Web Security</web-resource-name>
??? ??? ??? <url-pattern>/index.jsp</url-pattern>
??? ??? ??? <http-method>GET</http-method>
??? ??? </web-resource-collection>
??? ??? <auth-constraint>
??? ??? ??? <role-name>admin</role-name>
??? ??? </auth-constraint>
??? ??? <user-data-constraint>
??? ??? ??? 
??? ??? ??? <transport-guarantee>CONFIDENTIAL</transport-guarantee>
??? ??? </user-data-constraint>
??? </security-constraint>
??? ......
</web-app>
---------------------------------------------------------------------------------------------------------------------------------
四種認(rèn)證類型：

BASIC：HTTP規(guī)范，Base64
<web-app>
??? ......
??? <login-config>
??? ??? <auth-method>BASIC</auth-method>
??? </login-config>
??? ......
</web-app>

DIGEST:HTTP規(guī)范，數(shù)據(jù)完整性強(qiáng)一些，但不是SSL
<web-app>
??? ......
??? <login-config>
??? ??? <auth-method>DIGEST</auth-method>
??? </login-config>
??? ......
</web-app>

CLIENT-CERT：J2EE規(guī)范，數(shù)據(jù)完整性很強(qiáng)，公共鑰匙（PKC）
<web-app>
??? ......
??? <login-config>
??? ??? <auth-method>CLIENT-CERT</auth-method>
??? </login-config>
??? ......
</web-app>

FORM：J2EE規(guī)范，數(shù)據(jù)完整性非常弱，沒有加密，允許有定制的登陸界面。
<web-app>
??? ......
??? <login-config>
??? ??? <auth-method>FORM</auth-method>
??? ??? <form-login-config>
??? ??? ??? <form-login-page>/login.jsp</form-login-page>
??? ??? ??? <form-error-page>/error.jsp</form-error-page>
??? ??? </form-login-config>
??? </login-config>
??? ......
</web-app>

登陸頁面表單的action，用戶名，密碼要用統(tǒng)一的名字：
<form action="j_security_check">
??? <input type="text" name="j_username" />
??? <input type="password" name="j_password" />
??? <input type="submit" value="enter" />
</form>
