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. <struts>
  6. <constant name="struts.devMode" value="true" />
  7. <package name="basic" extends="struts-default">
  8. <action name="index" class="cn.ssm.sample.action.IndexAction" method="execute">
  9. <result name="success">/WEB-INF/jsp/Index.jsp</result>
  10. </action>
  11. </package>
  12. </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. <filter-mapping>
  6. <filter-name>struts2</filter-name>
  7. <url-pattern>/*</url-pattern>
  8. </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

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. import com.opensymphony.xwork2.ActionSupport;
  3. public class IndexAction extends ActionSupport{
  4. @Override
  5. public String execute() throws Exception {
  6. // TODO Auto-generated method stub
  7. return super.execute();
  8. }
  9. }
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">
<html>
<head>
<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. <beans xmlns="http://www.springframework.org/schema/beans"
  3. xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"

	<!-- 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>

  6. value="jdbc:mysql://localhost:3306/ssmsample?useUnicode=true&characterEncoding=utf8"></property>
  7. <property name="username" value="root"></property>
  8. <property name="password" value="admin"></property>
  9. </bean>
  10. <!-- transaction manager, use JtaTransactionManager for global tx -->
  11. <bean id="transactionManager"
  12. class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
  13. <property name="dataSource" ref="dataSource" />
  14. </bean>
  15. <!-- define the SqlSessionFactory -->
  16. <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
  17. <property name="dataSource" ref="dataSource" />
  18. <property name="typeAliasesPackage" value="cn.ssm.sample.dto" />
  19. </bean>
  20. <!-- scan for mappers and let them be autowired -->
  21. <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
  22. <property name="basePackage" value="cn.ssm.sample.dao" />
  23. </bean>
	<!-- 数据源配置 -->
	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
		destroy-method="close">
		<property name="driverClassName" value="com.mysql.jdbc.Driver"></property>

		<property name="username" value="root"></property>
		<property name="password" value="admin"></property>
	</bean>

	<!-- transaction manager, use JtaTransactionManager for global tx -->
	<bean id="transactionManager"
		class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<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">
