篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Spring3.2+mybatis3.2+Struts2.3整合相关的知识，希望对你有一定的参考价值。
1.Spring3.2不能用于JDK1.8，只能用于JDK1.7。JDK1.8用spring4.0.
2.导入的jar包
3.目录结构:
4.配置Spring
配置数据库信息:

配置service
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd "> <!--4.注解扫描service --> <!-- 4.开启组件自动扫描，也就是启用注解。前提是导入spring-context-3.2.xsd约束和引入新的命名空间，注解扫描service出错了 --> <context:component-scan base-package="cn.xm.service"></context:component-scan> <!-- userService配置 --> <!-- <bean name="userService" class="cn.xm.service.impl.UserServiceImpl"></bean> --> </beans>
配置Action
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd "> <!-- 与struts2整合的配置 --> <!-- Action配置 --> <bean name="userAction" class="cn.xm.web.action.UserAction" scope="prototype"> <property name="userService" ref="userService"></property> </bean> </beans>
4.配置Struts
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd"> <struts> <!-- package的名字必须唯一！只能拦截.action请求 默认值:class:com.opensymphony.xwork2.ActionSupport method:execute result的name属性:success 方法中返回success即可跳转到结果对应的页面 --> <!-- ### 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 --> <constant name="struts.custom.i18n.resources" value="errors"></constant> <!-- struts.objectFactory = spring :将Struts创建对象工厂改为Spring struts.objectFactory.spring.autoWire = name spring自动装配Struts的依赖属性(默认开启) --> <constant name="struts.objectFactory" value="spring"></constant> <!-- 第一个package命名空间 --> <package name="user" namespace="/" extends="struts-default"> <action name="user_*" class="userAction" method="{1}"> <result>/index.jsp</result> </action> </package> </struts>
5.配置mybatis
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <!-- 只需要定义个别名,这个应该有--> <typeAliases > <package name="cn.xm.pojo"/> </typeAliases> <!-- 动态代理也不需要配置这个扫描，留着也行 --> <mappers> <!-- 原始DAO开发使用这个手动加载xml --> <package name="cn.xm.mapper"/> </mappers> </configuration>
6.web.xml
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"> <display-name>xm</display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/applicationContext-*.xml</param-value> </context-param> <!-- 处理POST提交乱码问题 --> <filter> <filter-name>encoding</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>encoding</filter-name> <url-pattern>*.action</url-pattern> </filter-mapping> <filter> <filter-name>EncodingFilter</filter-name> <filter-class>cn.xm.web.filter.EncodingFilter</filter-class> </filter> <filter-mapping> <filter-name>EncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
7.总结:
要想使用sring扫描需要在配置文件中开启自动扫描service
<context:component-scan base-package="cn.xm.service"></context:component-scan>
要想在Service装配动态代理对象
