Eclipse中 struts2 + spring3 + mybatis3 环境搭建

「爱情、让人受尽委屈。」 2022-08-26 14:20 150阅读 0赞

公司要用struts2 + spring3 + mybatis3做项目，尝试着在家鼓捣了一下。

**1. 框架下载**

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

spring3: [http://www.springsource.org/spring-framework][http_www.springsource.org_spring-framework] 下载 spring-framework-3.2.2-dist.zip

mybatis3: [http://code.google.com/p/mybatis/][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 plain][view plain] [copy][view plain]

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>

3.2 修改web.xml

**\[html\]** [ view plain][view plain] [copy][view plain]

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>

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 plain][view plain] [copy][view plain]

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

3.4 建个测试用的IndexAction.java和Index.jsp

**\[java\]** [ view plain][view plain] [copy][view plain]

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. \}

**\[html\]** [ view plain][view plain] [copy][view plain]

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>

3.5 测试struts2

运行服务，在浏览器输入[http://localhost:8080/ssm\_example/index][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 plain][view plain] [copy][view plain]

1.  <?xml version="1.0" encoding="UTF-8"?>
2.  
3.  <beans xmlns="http://www.springframework.org/schema/beans"
4.  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
5.  xmlns:tx="http://www.springframework.org/schema/tx" xmlns:jdbc="http://www.springframework.org/schema/jdbc"
6.  xmlns:context="http://www.springframework.org/schema/context"
7.  xsi:schemaLocation="
8.  http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
9.  http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
10. http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd
11. http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
12. http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">
13. 
14. 
16. <context:component-scan
17. base-package="cn.ssm.sample.action,cn.ssm.sample.service" />
18. 
19. 
20. <context:annotation-config />
21. 
22. 
23. <tx:annotation-driven />
24. 
25. </beans>

4.2 修改web.xml

**\[html\]** [ view plain][view plain] [copy][view plain]

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>

4.3 添加相关jar包

**\[html\]** [ view plain][view plain] [copy][view plain]

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

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][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 plain][view plain] [copy][view plain]

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');

5.2 修改applicationContext.xml

**\[html\]** [ view plain][view plain] [copy][view plain]

1.  
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"
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. 
11. 
12. <bean id="transactionManager"
13. class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
14. <property name="dataSource" ref="dataSource" />
15. </bean>
16. 
17. 
18. <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
19. <property name="dataSource" ref="dataSource" />
20. <property name="typeAliasesPackage" value="cn.ssm.sample.dto" />
21. </bean>
22. 
23. 
24. <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
