Struts总结

一：model1和model2的区别

     model1：jsp既做控制也做显示

     model2:即mvc，jsp、taglib做显示、ActionServlet做控制、其他做model

二：struts的体系结构

                                struts-config.xml

                                          |

                                          |

request------------------ActionServlet---（ActionMapping）-----------                                                                                                        |

                                                                                                      Action(调用Model处理ActionForm)

                                                                                                        |

response----------------View(jsp,tags)--(ActionForward)---------------

三：核心组件：ActionServlet、ActionMapping、Action、ActionForm、ActionForward

四：struts配置文件：ApplicationResource.properties、struts-config.xml

五：struts标签库：struts-html.tld、struts-bean.tld、struts-logic.tld等

 

六：struts工作流

ActionServlet接收用户请求、ActionMapping映射配置文件、RequestProcessor代理ActionServlet处理请求、Action响应处理类、ActionForward转发、ActionForm保存用户表单信息、ActionErrors保存错误信息。

 

七：struts-config.xml配置

<data-sources>

<form-bean>

<global-exception>

<global-forward>

<action-mapping>

<controller>

<message-resources>

<plug-in>

 

八：表单

ActionForm、DynaActionForm、DynaValidatorForm、

 

九：Action处理器

继承Action

继承ForwardAction

继承IncludeAction

继承DispatchAction

继承LookupDispatchAction

继承SwitchAction

 

十：标签库

StrutsHTML

作为生成html表单和显示错误信息和正常信息

<html:errors>显示错误信息

<html:messages>显示正常信息

StrutsBean访问Http请求和jsp隐式对象

注意：<bean:message>国际化信息

<bean:include>

<bean:write name="xxx" property="id">

Struts Logic

<logic:equal>

<logic:notEqual>

<logic:greaterEqual>

<logic:greaterThan>

<logic:lessEqual>

<logic:lessThan>

 

<logic:match>

<logic:notMatch>

 

<logic:Empty>

<logic:notEmpty>

 

<logic:persent>

<logic:notPresent>

 

<logic:messagesPresent>

<logic:messagesNotPresent>

 

<logic:iterator>

 

<logic:forward>

<logic:redirect>

 

十一：国际化

 

十二：struts数据校验

启动Validator插件

配置validator-rules.xml

创建校验ActionForm

配置validator.xml

配置ApplicationResource.properties

启用客户端

 

基于Form-bean验证

1.ActionForm继承ValidatorForm

2.DynaValidatorForm

 

基于路径验证

 

3.ActionForm继承ValidatorActionForm

4.DynaValidatorActionForm
