  • struts2 + spring3 + mybatis3 环境搭建

    struts2 + spring3 + mybatis3 

    1. 框架下载

    struts2: http://struts.apache.org/ 下载 struts-2.3.14-all.zip

    spring3: http://www.springsource.org/spring-framework 下载 spring-framework-3.2.2-dist.zip

    mybatis3: http://code.google.com/p/mybatis/ 下载 mybatis-3.2.2.zip 和 mybatis-spring-1.2.0-bundle.zip

    2. 建示例工程

    在Eclipse中新建示例工程，步骤就不详述了，我把工程取名为ssm_example。

    3. struts2配置

    3.1 src下创建struts.xml配置文件

     

    [html] view plaincopyprint?
    1. <?xml version="1.0" encoding="UTF-8"?>  
    2. <!DOCTYPE struts PUBLIC  
    3.     "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"  
    4.     "http://struts.apache.org/dtds/struts-2.0.dtd">  
    5.   
    6. <struts>  
    7.   
    8.     <constant name="struts.devMode" value="true" />  
    9.   
    10.     <package name="basic" extends="struts-default">  
    11.         <action name="index" class="cn.ssm.sample.action.IndexAction" method="execute">  
    12.             <result name="success">/WEB-INF/jsp/Index.jsp</result>  
    13.         </action>  
    14.     </package>  
    15.   
    16. </struts>  
    <?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>

	<constant name="struts.devMode" value="true" />

	<package name="basic" extends="struts-default">
		<action name="index" class="cn.ssm.sample.action.IndexAction" method="execute">
			<result name="success">/WEB-INF/jsp/Index.jsp</result>
		</action>
	</package>

</struts>

    3.2 修改web.xml

     

    [html] view plaincopyprint?
    1. <filter>  
    2.         <filter-name>struts2</filter-name>  
    3.         <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>  
    4.     </filter>  
    5.   
    6.     <filter-mapping>  
    7.         <filter-name>struts2</filter-name>  
    8.         <url-pattern>/*</url-pattern>  
    9.     </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>

    3.3 从解压的struts-2.3.14-all的lib文件夹下，挑选了必须的和比较常用的jar包，放入WEB-INF/lib的文件夹下

     

    [html] view plaincopyprint?
    1. commons-fileupload-1.2.2.jar  
    2. commons-io-2.0.1.jar  
    3. commons-lang-2.4.jar  
    4. commons-lang3-3.1.jar  
    5. commons-logging-1.1.1.jar  
    6. commons-logging-api-1.1.jar  
    7. freemarker-2.3.19.jar  
    8. javassist-3.11.0.GA.jar  
    9. ognl-3.0.6.jar  
    10. struts2-core-2.3.14.jar  
    11. xwork-core-2.3.14.jar  
    commons-fileupload-1.2.2.jar
commons-io-2.0.1.jar
commons-lang-2.4.jar
commons-lang3-3.1.jar
commons-logging-1.1.1.jar

javassist-3.11.0.GA.jar
ognl-3.0.6.jar
struts2-core-2.3.14.jar
xwork-core-2.3.14.jar

    3.4 建个测试用的IndexAction.java和Index.jsp

     

    [java] view plaincopyprint?
    1. package cn.ssm.sample.action;  
    2.   
    3. import com.opensymphony.xwork2.ActionSupport;  
    4.   
    5. public class IndexAction extends ActionSupport{  
    6.   
    7.     @Override  
    8.     public String execute() throws Exception {  
    9.         // TODO Auto-generated method stub   
    10.         return super.execute();  
    11.     }  
    12.   
    13. }  
    package cn.ssm.sample.action;

import com.opensymphony.xwork2.ActionSupport;

public class IndexAction extends ActionSupport{

	@Override
	public String execute() throws Exception {
		// TODO Auto-generated method stub
		return super.execute();
	}

}

    [html] view plaincopyprint?
    1. <%@ page language="java" contentType="text/html; charset=UTF-8"  
    2.     pageEncoding="UTF-8"%>  
    3. <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">  
    4. <html>  
    5. <head>  
    6. <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">  
    7. <title>Insert title here</title>  
    8. </head>  
    9. <body>  
    10.     Hello world!  
    11. </body>  
    12. </html>  
    <%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
	Hello world!
</body>
</html>

    3.5 测试struts2

    运行服务，在浏览器输入http://localhost:8080/ssm_example/index，如果配置没有错误，那么会出现Hello world！

    4. spring3配置

    4.1 config/spring下创建applicationContext.xml配置文件

     

    [html] view plaincopyprint?
    1. <?xml version="1.0" encoding="UTF-8"?>  
    2.   
    3. <beans xmlns="http://www.springframework.org/schema/beans"

	<!-- enable autowire -->
	<context:annotation-config />

	<!-- enable transaction demarcation with annotations -->
	<tx:annotation-driven />
	
</beans>

    4.2 修改web.xml

     

    [html] view plaincopyprint?
    1. <listener>  
    2.     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  
    3. </listener>  
    4. <context-param>  
    5.     <param-name>contextConfigLocation</param-name>  
    6.     <param-value>/WEB-INF/classes/applicationContext.xml  
    7.        </param-value>  
    8. </context-param>  
    	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>/WEB-INF/classes/applicationContext.xml
        </param-value>
	</context-param>

    4.3 添加相关jar包

     

    [html] view plaincopyprint?
    1. aopalliance-1.0.jar  
    2. spring-aop-3.2.2.RELEASE.jar  
    3. spring-beans-3.2.2.RELEASE.jar  
    4. spring-context-3.2.2.RELEASE.jar  
    5. spring-core-3.2.2.RELEASE.jar  
    6. spring-expression-3.2.2.RELEASE.jar  
    7. spring-jdbc-3.2.2.RELEASE.jar  
    8. spring-tx-3.2.2.RELEASE.jar  
    9. spring-web-3.2.2.RELEASE.jar  
    10. struts2-spring-plugin-2.3.14.jar  
    aopalliance-1.0.jar
spring-aop-3.2.2.RELEASE.jar
spring-beans-3.2.2.RELEASE.jar
spring-context-3.2.2.RELEASE.jar
spring-core-3.2.2.RELEASE.jar
spring-expression-3.2.2.RELEASE.jar
spring-jdbc-3.2.2.RELEASE.jar
spring-tx-3.2.2.RELEASE.jar
spring-web-3.2.2.RELEASE.jar
struts2-spring-plugin-2.3.14.jar

    4.4 修改struts.xml文件

    添加：<constant name="struts.objectFactory" value="spring"></constant>

    并且把class="cn.ssm.sample.action.IndexAction"改成class="indexAction" 

    4.5 修改Action

    在IndexAction的类上，加上@Controller，这样Spring就能自动实例化成indexAction对象了。

    4.6 测试spring

    运行服务，在浏览器输入http://localhost:8080/ssm_example/index，如果配置没有错误，那么依然会出现Hello world！

    5. mybatis3配置

    5.1 数据库准备

    这里采用mysql，下面的sql文来运行。

     

    [sql] view plaincopyprint?
    1. CREATE SCHEMA `ssmsample` DEFAULT CHARACTER SET utf8 ;  
    2. CREATE  TABLE `ssmsample`.`user` (`id` INT NOT NULL AUTO_INCREMENT, `name` VARCHAR(45) NULL, PRIMARY KEY('id') );  
    3. INSERT INTO `ssmsample`.`user` (`id`,`name`) VALUES (1,'Ethan');  
    CREATE SCHEMA `ssmsample` DEFAULT CHARACTER SET utf8 ;
CREATE  TABLE `ssmsample`.`user` (`id` INT NOT NULL AUTO_INCREMENT, `name` VARCHAR(45) NULL, PRIMARY KEY('id') );
INSERT INTO `ssmsample`.`user` (`id`,`name`) VALUES (1,'Ethan');

    5.2 修改applicationContext.xml

     

    [html] view plaincopyprint?
    1. <!-- 数据源配置 -->  
    2. <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"  
    3.     destroy-method="close">  
    4.     <property name="driverClassName" value="com.mysql.jdbc.Driver"></property>  
    5.     <property name="url"

    10.   
    11. <!-- transaction manager, use JtaTransactionManager for global tx -->  
    12. <bean id="transactionManager"  
    13.     class="org.springframework.jdbc.datasource.DataSourceTransactionManager">  
    14.     <property name="dataSource" ref="dataSource" />  
    15. </bean>  
    16.   
    17.    <!-- define the SqlSessionFactory -->  
    18.    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">  
    19.        <property name="dataSource" ref="dataSource" />

    21.    </bean>  
    22.   
    23.    <!-- scan for mappers and let them be autowired -->  
    24.    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">  
    25.        <property name="basePackage" value="cn.ssm.sample.dao" />  
    26.    </bean>  
    	<!-- 数据源配置 -->
	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
		destroy-method="close">

	</bean>

	<!-- transaction manager, use JtaTransactionManager for global tx -->
	<bean id="transactionManager"

		<property name="dataSource" ref="dataSource" />
	</bean>

    <!-- define the SqlSessionFactory -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="typeAliasesPackage" value="cn.ssm.sample.dto" />
    </bean>

    <!-- scan for mappers and let them be autowired -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="cn.ssm.sample.dao" />
    </bean>

    5.3 创建和修改相关类

    UserMapper.java

     

    [java] view plaincopyprint?
    1. package cn.ssm.sample.dao;  
    2.
