最近用Idea开发,idea是1款综合的相对较新的Java IDE。Idea支持很多整合功能,我觉得挺好用的。Idea可以校订xml,支持jsp的调试。最使我喜欢的是,写spring配置文件的时候,写的1些路径都可以自己找到。classpath自己有代码的提示,超级的智能。
在整合框架之前,先配置1下JER运行环境,配置maven仓库。
1.File——ProjectStructure——Project——New… 选择jdk的安装环境
2.File——Settings——Maven——Maven home directory选择自己maven的安装目录。下面是maven管理jar包的地方。
Spring目的:就是让对象与对象(模块与模块)之间的关系没有通过代码来关联,都是通过配置类说明管理的,简单的说,不用在代码里写死new某个对象,而是全部在配置文件中进行了配置。Spring是1个容器,凡是在容器里的对象才会有Spring所提供的这些服务和功能。
Spring MVC属于SpringFrameWork的后续产品,已融会在Spring Web Flow里面。Spring MVC 分离了控制器、模型对象、分派器和处理程序对象的角色,这类分离让它们更容易进行定制。
MyBatis 是支持普通 SQL查询,存储进程和高级映照的优秀持久层框架。MyBatis 消除几近所有的JDBC代码和参数的手工设置和结果集的检索。MyBatis 使用简单的 XML或注解用于配置和原始映照,将接口和 Java 的POJOs(Plain Old Java Objects,普通的 Java对象)映照成数据库中的记录。
用的框架的版本分别是:
spring版本号 4.0.2.RELEASE
mybatis版本号 3.2.6
Spring MVC版本号 4.0.2 RELEASE
log4j日志文件管理包版本号 {slf4j |1.7.7} { log4j |1.2.17}
项目目录以下:
1.编写pom.xml,引入jar包

2.建立jdbc.properties,配置数据库信息
driver=com.mysql.jdbc.Driver
url=jdbc:mysql:///ordersystem
username=root
password=123456
#定义初始连接数
initialSize=0
#定义最大连接数
maxActive=20
#定义最大空闲
maxIdle=20
#定义最小空闲
minIdle=1
#定义最长等待时间
maxWait=60000
3.log4j.properties配置文件
#定义LOG输出级别
log4j.rootLogger=INFO,Console,File
#定义日志输出目的地为控制台
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
#可以灵活地指定日志输出格式,下面1行是指定具体的格式
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n
#文件大小到达指定尺寸的时候产生1个新的文件
log4j.appender.File = org.apache.log4j.RollingFileAppender
#指定输出目录
log4j.appender.File.File = logs/ssm.log
#定义文件最大大小
log4j.appender.File.MaxFileSize = 10MB
# 输出所以日志,如果换成DEBUG表示输出DEBUG以上级别日志
log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n
4.建立spring-Mybatis.xml配置文件
<?xml version="1.0" encoding="UTF⑻"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans⑶.1.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context⑶.1.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc⑷.0.xsd">
<!-- 自动扫描 -->
<context:component-scan base-package="com.cn.order" />
<!-- 引入配置文件 -->
<bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="classpath:jdbc.properties" />
</bean>
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="${driver}" />
<property name="url" value="${url}" />
<property name="username" value="${username}" />
<property name="password" value="${password}" />
<!-- 初始化连接大小 -->
<property name="initialSize" value="${initialSize}"></property>
<!-- 连接池最大数量 -->
<property name="maxActive" value="${maxActive}"></property>
<!-- 连接池最大空闲 -->
<property name="maxIdle" value="${maxIdle}"></property>
<!-- 连接池最小空闲 -->
<property name="minIdle" value="${minIdle}"></property>
<!-- 获得连接最大等待时间 -->
<property name="maxWait" value="${maxWait}"></property>
</bean>
<!-- spring和MyBatis完善整合,不需要mybatis的配置映照文件 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<!-- 自动扫描mapping.xml文件 -->
<property name="mapperLocations" value="classpath:com/cn/order/mapping/*.xml"></property>
</bean>
<!-- DAO接口所在包名,Spring会自动查找其下的类 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.cn.order.dao" />
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
</bean>
<!-- (事务管理)transaction manager, use JtaTransactionManager for global tx -->
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
</beans>
5.服务层接口 service
package com.cn.order.service;
import com.cn.order.pojo.User;
/**
* Created by azz-pc on 2016/5/24.
*/
public interface IUserService {
User getUserById(int userId);
}
6.服务层实现serviceImpl
package com.cn.order.service.impl;
import javax.annotation.Resource;
import org.springframework.stereotype.Service;
import com.cn.order.dao.IUserDao;
import com.cn.order.pojo.User;
import com.cn.order.service.IUserService;
/**
* Created by azz-pc on 2016/5/24.
*/
@Service("userService")
public class UserServiceImpl implements IUserService {
@Resource
private IUserDao userDao;
public User getUserById(int userId) {
return this.userDao.selectByPrimaryKey(userId);
}
}
7.Junit测试
测试类编写:
package org.zsl.testmybatis;
import javax.annotation.Resource;
import com.cn.order.pojo.*;
import com.cn.order.service.*;
import org.apache.log4j.Logger;
/*import org.apache.log4j.net.SyslogAppender;*/
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.context.ApplicationContext;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
@RunWith(SpringJUnit4ClassRunner.class) //表示继承了SpringJUnit4ClassRunner类
@ContextConfiguration(locations = {"classpath:spring-mybatis.xml"})
public class TestMyBatis {
private static Logger logger = Logger.getLogger(TestMyBatis.class);
private ApplicationContext ac = null;
@Resource
//private IUserService userService = null;
private ICardService cardService=null;
private Card card=new Card();
// @Before
// public void before() {
// ac = new ClassPathXmlApplicationContext("applicationContext.xml");
// userService = (IUserService) ac.getBean("userService");
// }
@Test
public void test1() {
// User user = userService.getUserById(1);
// System.out.println(user.getUsername());
// System.out.println(user.getPassword());
// System.out.println(user.getState());
// logger.info("值:"+user.getUsername());
// logger.info(JSON.toJSONString(user));
card.setCardid("E000010");
card.setPassword("33333");
card.setOwnername("xiaozhou");
card.setCash("10.0");
card.setCardtypeid(1);
card.setStatus("T");
cardService.insert(card);
System.out.println("insert success");
}
}
利用MyBatis Generator自动创建mapping,dao,pojo层,详情参见博客:http://blog.csdn.net/zhou2s_101216/article/details/51175818
输出insert success 证明 测试成功。
1.配置spring-mvc.xml
<?xml version="1.0" encoding="UTF⑻"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans⑶.1.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context⑶.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!-- 自动扫描该包,使SpringMVC认为包下用了@controller注解的类是控制器 -->
<context:component-scan base-package="com.cn.order.controller"/>
<!--<mvc:default-servlet-handler/>-->
<!--避免IE履行AJAX时,返回JSON出现下载文件 -->
<bean id="mappingJacksonHttpMessageConverter"
class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>text/html;charset=UTF⑻</value>

<ref bean="mappingJacksonHttpMessageConverter"/> <!-- JSON转换器 -->
</list>
</property>
</bean>
<!-- 定义跳转的文件的前后缀 ,视图模式配置-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- 这里的配置我的理解是自动给后面action的方法return的字符串加上前缀和后缀,变成1个 可用的url地址 -->
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<!-- 默许编码 -->
<property name="defaultEncoding" value="utf⑻"/>
<!-- 文件大小最大值 -->
<property name="maxUploadSize" value="10485760000"/>
<!-- 内存中的最大值 -->
<property name="maxInMemorySize" value="40960"/>
</bean>
<bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="classpath:jdbc.properties"/>
</bean>
</beans>
2.配置web.xml
<?xml version="1.0" encoding="UTF⑻"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
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>
<!-- Spring和mybatis的配置文件 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-mybatis.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>UTF⑻</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- Spring监听器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 避免Spring内存溢出监听器 -->
<listener>
<listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
</listener>
<!-- Spring MVC servlet -->
<servlet>
<servlet-name>SpringMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
<async-supported>true</async-supported>
</servlet>
<servlet-mapping>
<servlet-name>SpringMVC</servlet-name>
<!-- 此处可以可以配置成*.do,对应struts的后缀习惯 -->
<url-pattern>/</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>*.css</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>*.js</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>/index.jsp</welcome-file>
</welcome-file-list>
<!-- 配置SESSION超时,单位是分钟 -->
<session-config>
<session-timeout>15</session-timeout>
</session-config>
</web-app>
3.前台使用的是,spring mvc、bootstrap、angularjs
showUser.jsp
