Spring+Struts2+Mybatis在Intellij下的整合
环境：jdk 1.8, tomcat 8.0.38;
开发工具：Intellj;
具体步骤：
1. 创建一个maven下的web项目
2. 配置相应的jar文件，具体的配置方式为：
<dependencies>

3. 创建一个控制层的实体类：LoginAction.java, 并新建一个struts的配置文件struts.xml
具体的代码为：
import com.ssm.service.DeptService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
@Controller
public class LoginAction {
@Autowired
private DeptService deptService;
private String uname;
private String upass;
public String login() {
if("aa".equals(uname)&&"aa".equals(upass)){
return "success";
}else
return "error";
}
public String getUname() {
return uname;
}
public void setUname(String uname) {
this.uname = uname;
}
public String getUpass() {
return upass;
}
public void setUpass(String upass) {
this.upass = upass;
}
}
struts.xml:配置文件：
<struts> <constant name="struts.i18n.encoding" value="UTF-8">constant> <constant name="struts.action.extension" value="do,action" /> <constant name="struts.enable.DynamicMethodInvocation" value="true" /> <package name="user" namespace="/user" extends="struts-default" strict-method-invocation="false"> <action name="login" class="com.ssm.action.LoginAction" method="login"> <result type="dispatcher" name="input">/login.jspresult> <result type="dispatcher" name="success">/success.jspresult> <result type="dispatcher" name="error">/error.jspresult> action> package> struts>
4. 对web.xml文件做如下配置：
<filter>
<filter-name>struts2filter-name>
<filter-class>
org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter
filter-class>
filter>
<filter-mapping>
<filter-name>struts2filter-name>
<url-pattern>/*url-pattern>
filter-mapping>
<welcome-file-list>
<welcome-file>login.jspwelcome-file>
welcome-file-list>
5. 配置MyBatis， 新建一个xml文件，准备一个mybatis-generator-core-1.3.2.jar, 其位置关系如下：
具体作如下配置：
xml version="1.0" encoding="UTF-8"?>
generatorConfiguration
PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
"http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>
<classPathEntry
location="C:/Users/Administrator/.m2/repository/mysql/mysql-connector-java/5.1.38/mysql-connector-java-5.1.38.jar"/>
<context id="DB2Tables" targetRuntime="MyBatis3">
<commentGenerator>
<property name="suppressDate" value="true"/>
<property name="suppressAllComments" value="true"/>
commentGenerator>
<jdbcConnection driverClass="com.mysql.jdbc.Driver"
connectionURL="jdbc:mysql://localhost:3306/test?serverTimezone=UTC&useSSL=true"
userId="root"
password="root">
jdbcConnection>
<javaTypeResolver>
<property name="forceBigDecimals" value="false"/>
javaTypeResolver>
<javaModelGenerator targetPackage="com.ssm.domain"
targetProject="../../java">
<property name="enableSubPackages" value="true"/>
<property name="trimStrings" value="true"/>
javaModelGenerator>
<sqlMapGenerator targetPackage="com.ssm.mapping"
targetProject="../../java">
<property name="enableSubPackages" value="true"/>
sqlMapGenerator>
<javaClientGenerator type="XMLMAPPER"
targetPackage="com.ssm.dao" targetProject="../../java">
<property name="enableSubPackages" value="true"/>
javaClientGenerator>
<table tableName="tb_Dept" domainObjectName="Dept"
enableCountByExample="false" enableUpdateByExample="false"
enableDeleteByExample="false" enableSelectByExample="false"
selectByExampleQueryId="false">
table>
context>
generatorConfiguration>
然后，打开命令行窗口（win+R）：进入该配置文件所在的目录，然后，输入以下命令：
java -jar mybatis-generator-core-1.3.2.jar -configfile ../myBatisAuto/generatorConfig.xml -overwrite（需要注意的是：不能更改位置结构），此时相应的包下，已经生成了相应的实体类及dao层的文件；
6. 新建一个xml文件mybatisMapper.xml用来加载相应的mapping包下的资源，具体作如下配置：
xml version="1.0" encoding="UTF-8" ?>
configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<mappers>
<mapper resource="com/ssm/mapping/DeptMapper.xml"/>
mappers>
configuration>
7. 创建一个Spring的配置文件applicationContext.xml文件，并做以下配置：
<context:component-scan base-package="com.ssm">context:component-scan> <bean id="ds" class="com.alibaba.druid.pool.DruidDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver">property> <property name="url" value="jdbc:mysql:///test?useSSL=false">property> <property name="username" value="root">property> <property name="password" value="root">property> bean> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="ds">property> <property name="configLocation" value="classpath:mybatisMapper.xml">property> bean> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.ssm.dao">property> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory">property> bean> <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="ds" /> bean> <tx:annotation-driven transaction-manager="txManager" />
8. 在webapp下创建几个jsp的测试页面，其结构如下：
页面 login.jsp:
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
success.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
登录成功
error.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
登陆失败
9. 接下来用注解的方式，使相应层的类受Spring的管理，具体的注解方式，可以查阅其他资料获取，此处不再一一赘述；
