我这边使用的是intellij idea15
1.new maven webapp project
2.添加groupId和artifactId
3.选择maven路径和maven仓库路径
最后确定之后，等1分钟左右时间，maven会自动补全项目结构。如果没有，自己新建src/main/java等结构吧
4.pom.xml中添加依赖包
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

然后在src/main/resoures目录下分别新建配置文件目录：spring、mybatis、springmvc、properties
配置spring文件：在sping目录下新建applicationContext.xml：
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

添加数据源类com.mlxs.mvc.common.MutipleDataSource：
package com.mlxs.mvc.common; import org.springframework.jdbc.datasource.lookup.AbstractRoutingDataSource; /** * MutipleDataSource: * * @author yangzhenlong * @since 2016/7/13 */ public class MutipleDataSource extends AbstractRoutingDataSource { private static final ThreadLocal<String> dataSourceKey = new InheritableThreadLocal<String>(); public static void setDataSourceKey(String dataSource) { dataSourceKey.set(dataSource); } @Override protected Object determineCurrentLookupKey() { return dataSourceKey.get(); } }
在mybatis目录下添加mybatis-config.xml:
<?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> <settings> <!-- setting name="cacheEnable" value="true"/--> <setting name="useGeneratedKeys" value="false"/> <setting name="logImpl" value="LOG4J"/><!--增加mybatis日志--> </settings> <mappers> <!--这里不需要添加mapper.xml文件，在spring的sqlSessionFactory中已经配置了自动扫描--> </mappers> </configuration>
在spingmvc目录下添加spring-mvc.xml:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd"> <!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 --> <mvc:annotation-driven /> <!-- 使用注解的包，包括子集 --> <context:component-scan base-package="com.mlxs.mvc.controller" /> <!-- 解决js,css,images访问不到的问题--> <!--<mvc:resources mapping="/js/**" location="/js/" /> <mvc:resources mapping="/css/**" location="/css/" /> <mvc:resources mapping="/images/**" location="/images/" /> <mvc:resources mapping="/template/**" location="/template/" />--> <!-- 文件上传配置注意:这里申明的id必须为multipartResolver --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="maxUploadSize" value="500000"/> </bean> <!-- 简单的异常处理 --> <bean id="exceptionResolver" class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver"> <property name="exceptionMappings"> <props> <!-- 映射目录为/WEB-INF/jsp/error/upload_error.jsp --> <prop key="org.springframework.web.multipart.MaxUploadSizeExceededException">/error/upload_error</prop> </props> </property> </bean> <!-- 配置JSP视图 --> <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/> <property name="prefix" value="/WEB-INF/jsp/"/> <property name="suffix" value=".jsp"/> <property name="contentType" value="text/html;charset=UTF-8"/> <property name="order" value="1"/> </bean> </beans>
在properties目录下添加jdbc.properties和log4j.properties文件：
jdbc.properties：
#============================================================================ # MySQL #============================================================================ jdbc.mysql.driver=com.mysql.jdbc.Driver jdbc.mysql.url=jdbc:mysql://localhost:3307/test?useUnicode=true&characterEncoding=utf8 jdbc.mysql.username=root jdbc.mysql.password=root #============================================================================ # MS SQL Server #============================================================================ jdbc.sqlserver.driver=com.microsoft.sqlserver.jdbc.SQLServerDriver jdbc.sqlserver.url=jdbc:sqlserver://127.0.0.1:1433;database=angular-demo; jdbc.sqlserver.username=root jdbc.sqlserver.password=root #============================================================================ # ORACLE #============================================================================ jdbc.orcl.driver=oracle.jdbc.OracleDriver jdbc.orcl.url=jdbc:oracle:thin:@localhost:1526:angular-demo jdbc.orcl.username=root jdbc.orcl.password=root #============================================================================ # common settings #============================================================================ jdbc.initialSize=5 jdbc.minIdle=5 jdbc.maxIdle=20 jdbc.maxActive=100 jdbc.maxWait=100000 jdbc.defaultAutoCommit=false jdbc.removeAbandoned=true jdbc.removeAbandonedTimeout=600 jdbc.testWhileIdle=true jdbc.timeBetweenEvictionRunsMillis=60000 jdbc.numTestsPerEvictionRun=20 jdbc.minEvictableIdleTimeMillis=300000
log4j.properties：

在webapp/WEB-INF/web.xml中配置：
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0"> <display-name>Archetype Created Web Application</display-name> <description>testSpringMVC</description> <!--加载spring配置文件--> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/applicationContext.xml</param-value> </context-param> <!-- 编码过滤器 --> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <async-supported>true</async-supported> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- urlrewrite--> <filter> <filter-name>UrlRewriteFilter</filter-name> <filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class> </filter> <filter-mapping> <filter-name>UrlRewriteFilter</filter-name> <url-pattern>/*</url-pattern> <dispatcher>REQUEST</dispatcher> <dispatcher>FORWARD</dispatcher> </filter-mapping> <!-- 日志记录 --> <context-param> <!-- 日志配置文件路径 --> <param-name>log4jConfigLocation</param-name> <param-value>classpath:properties/log4j.properties</param-value> </context-param> <context-param> <!-- 日志页面的刷新间隔 --> <param-name>log4jRefreshInterval</param-name> <param-value>6000</param-value> </context-param> <listener> <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> </listener> <!-- Spring监听 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- Spring MVC配置 --> <servlet> <servlet-name>springMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!-- 自定义spring mvc的配置文件名称和路径 --> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:springmvc/spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springMVC</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <error-page> <error-code>404</error-code> <location>/error/404</location> </error-page> <error-page> <error-code>500</error-code> <location>/error/500</location> </error-page> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> <welcome-file>/index.htm</welcome-file> <welcome-file>/index.html</welcome-file> </welcome-file-list> </web-app>
好了，现在所有的配置都完成了，下面就是写model、dao(我这里是mapper，对应mybatis的mapper类)、service、controller类：
1.com.mlxs.mvc.model.User：
package com.mlxs.mvc.model;
/**
* User:
*
* @author yangzhenlong
* @since 2016/7/13
*/
public class User {
private int id;
private String loginName;
private String loginPwd;
private String realName;
private int sex;
private int age;
private String phone;
private String address;
private String remark;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getLoginName() {
return loginName;
}
public void setLoginName(String loginName) {
this.loginName = loginName;
}
public String getLoginPwd() {
return loginPwd;
}
public void setLoginPwd(String loginPwd) {
this.loginPwd = loginPwd;
}
public String getRealName() {
return realName;
}
public void setRealName(String realName) {
this.realName = realName;
}
public int getSex() {
return sex;
}
public void setSex(int sex) {
this.sex = sex;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public String getRemark() {
return remark;
}
public void setRemark(String remark) {
this.remark = remark;
}
}
2.com.mlxs.mvc.mapper.UserMapper：
package com.mlxs.mvc.mapper; import com.mlxs.mvc.model.User; import java.util.List; /** * UserMapper: * * @author yangzhenlong * @since 2016/7/13 */ public interface UserMapper { public int save(User user); public int delete(int id); public int update(User user); public User queryByUser(User user); public List<User> queryAll(); }
3.com.mlxs.mvc.service.UserService
package com.mlxs.mvc.service; import com.mlxs.mvc.model.User; import java.util.List; /** * UserService: * * @author yangzhenlong * @since 2016/7/13 */ public interface UserService { public List<User> queryAll(); }
3.1com.mlxs.mvc.service.impl.UserServiceImpl
package com.mlxs.mvc.service.impl; import com.mlxs.mvc.mapper.UserMapper; import com.mlxs.mvc.model.User; import com.mlxs.mvc.service.UserService; import org.springframework.stereotype.Service; import javax.annotation.Resource; import java.util.List; /** * UserServiceImpl: * * @author yangzhenlong * @since 2016/7/13 */ @Service public class UserServiceImpl implements UserService { @Resource UserMapper userMapper; public List<User> queryAll() { return userMapper.queryAll(); } }
4.com.mlxs.mvc.controller.UserController：
package com.mlxs.mvc.controller; import com.mlxs.mvc.model.User; import com.mlxs.mvc.service.UserService; import org.springframework.stereotype.Controller; import org.springframework.ui.ModelMap; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import javax.annotation.Resource; import java.util.List; /** * UserController: * * @author yangzhenlong * @since 2016/7/13 */ @Controller @RequestMapping("/user") public class UserController { @Resource UserService userService; @RequestMapping(value = "/list", method = {RequestMethod.GET, RequestMethod.POST}) public String list(ModelMap modelMap){ List<User> userList = userService.queryAll(); modelMap.addAttribute("userList", userList); return "userlist"; } }
然后要添加mapper类对应的maper.xml文件：在resources/mybatis目录下添加：com.mlxs.mvc.mapper目录，然后新建：UserMapper.xml：
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="com.mlxs.mvc.mapper.UserMapper"> <insert id="save" parameterType="com.mlxs.mvc.model.User"> INSERT INTO `test`.`user`(`id`,`login_name`,`login_pwd`,`real_name`,`sex`,`age`,`phone`,`address`,`remark`) VALUES ( NULL, #{loginName},#{loginPwd},#{realName},#{sex},#{age},#{phone},#{address},#{remark}); </insert> <select id="queryAll" resultType="com.mlxs.mvc.model.User"> SELECT id, login_name loginName, login_pwd loginPwd, real_name realName, sex, age, phone, address, remark FROM test.user </select> </mapper>
对应的数据表DDL语句：
CREATE TABLE `user` ( `id` int(8) NOT NULL AUTO_INCREMENT, `login_name` varchar(64) DEFAULT NULL, `login_pwd` varchar(64) DEFAULT NULL, `real_name` varchar(64) DEFAULT NULL, `sex` tinyint(2) DEFAULT NULL COMMENT '性别（1男，2女）', `age` int(3) DEFAULT NULL COMMENT '年龄', `phone` varchar(11) DEFAULT NULL COMMENT '电话', `address` varchar(128) DEFAULT NULL COMMENT '地址', `remark` text COMMENT '备注', PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8
表中添加数据：
最后，在WEB-INF目录下新建jsp目录，再新建userlist.jsp:
