注意:javassist-3.18.1-GA.jar包與hibernate中的重複(只保留高版本便可)java
注意:這個包一旦導入,那麼struts2在啓動時就會尋找spring容器.找不到將會拋出異常mysql

struts2-spring-plugin-2.3.24.jarapi
查看默認配置文件從31行開始找到要配置的變量。session
### if specified, the default object factory can be overridden here
### Note: short-hand notation is supported in some cases, such as "spring"
### Alternatively, you can provide a com.opensymphony.xwork2.ObjectFactory subclass name here
# struts.objectFactory = spring
### specifies the autoWiring logic when using the SpringObjectFactory.
### valid values are: name, type, auto, and constructor (name is the default)
struts.objectFactory.spring.autoWire = name
添加常量到struts.xml
<!-- # struts.objectFactory = spring 將action的建立交給spring容器 struts.objectFactory.spring.autoWire = name spring負責裝配Action依賴屬性 --> <constant name="struts.objectFactory" value="spring"></constant>
<!-- 整合方案1:class屬性上仍然配置action的完整類名 struts2仍然建立action,由spring負責組裝Action中的依賴屬性 --> <action name="UserAction_*" class="cn.xyp.web.action.UserAction" method="{1}" > <result name="toHome" type="redirect" >/index.htm</result> <result name="error" >/login.jsp</result> </action>
不推薦理由:最好由spring完整管理action的生命週期.spring中功能才應用到Action上.
applicationContext.xml:
<!-- action --> <!-- 注意:Action對象做用範圍必定是多例的.這樣才符合struts2架構 --> <bean name="userAction" class="cn.itcast.web.action.UserAction" scope="prototype" > <property name="userService" ref="userService" ></property> </bean>
struts.xml:
<!-- 整合方案2:class屬性上填寫spring中action對象的BeanName 徹底由spring管理action生命週期,包括Action的建立 注意:須要手動組裝依賴屬性 --> <action name="UserAction_*" class="userAction" method="{1}" > <result name="toHome" type="redirect" >/index.htm</result> <result name="error" >/login.jsp</result> </action>
舉例:User.java
package cn.xyp.web.domain; import java.util.HashSet; import java.util.Set; public class User { private Long user_id; private String user_code; private String user_name; private String user_password; private Character user_state; public Long getUser_id() { return user_id; } public void setUser_id(Long user_id) { this.user_id = user_id; } public String getUser_code() { return user_code; } public void setUser_code(String user_code) { this.user_code = user_code; } public String getUser_name() { return user_name; } public void setUser_name(String user_name) { this.user_name = user_name; } public String getUser_password() { return user_password; } public void setUser_password(String user_password) { this.user_password = user_password; } public Character getUser_state() { return user_state; } public void setUser_state(Character user_state) { this.user_state = user_state; } @Override public String toString() { return "User [user_id=" + user_id + ", user_code=" + user_code + ", user_name=" + user_name + ", user_password=" + user_password + "]"; } }
