最近用Idea开发,idea是一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可以校正xml,支持jsp的调试。最让我喜欢的是,写spring配置文件的时候,写的一些路径都可以自己找到。classpath自己有代码的提示,超级的智能。

环境配置

在整合框架之前,先配置一下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。

概念

1.spring

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是一个容器,凡是在容器里的对象才会有Spring所提供的这些服务和功能。

2.Spring MVC

Spring MVC属于SpringFrameWork的后续产品,已经融合在Spring Web Flow里面。Spring MVC 分离了控制器、模型对象、分派器以及处理程序对象的角色,这种分离让它们更容易进行定制。

3.Mybatis

MyBatis 是支持普通 SQL查询,存储过程和高级映射的优秀持久层框架。MyBatis 消除了几乎所有的JDBC代码和参数的手工设置以及结果集的检索。MyBatis 使用简单的 XML或注解用于配置和原始映射,将接口和 Java 的POJOs(Plain Old Java Objects,普通的 Java对象)映射成数据库中的记录。

spring Mybatis整合

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}

项目目录如下:

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,下面一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一个新的文件
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="UTF-8"?>
<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-beans-3.1.xsd
                        http://www.springframework.org/schema/context
                        http://www.springframework.org/schema/context/spring-context-3.1.xsd
                        http://www.springframework.org/schema/mvc
                        http://www.springframework.org/schema/mvc/spring-mvc-4.0.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>
        <!-- 获取连接最大等待时间 -->
        <property name="maxWait" value="${maxWait}"></property>
    </bean>

    <!-- spring和MyBatis完美整合,不需要mybatis的配置映射文件 -->
    <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。

整合springMVC

1.配置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"

    <!-- 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执行AJAX时,返回JSON出现下载文件 -->
    <bean id="mappingJacksonHttpMessageConverter"
          class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">

        </property>
    </bean>
    <!-- 启动SpringMVC的注解功能,完成请求和注解POJO的映射 -->
    <bean
            class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
        <property name="messageConverters">
            <list>
                <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,变成一个 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">
        <!-- 默认编码 -->
        <property name="defaultEncoding" value="utf-8"/>
        <!-- 文件大小最大值 -->
        <property name="maxUploadSize" value="10485760000"/>
        <!-- 内存中的最大值 -->

    </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="UTF-8"?>
<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">

  <!-- 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>UTF-8</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>
  <!-- 防止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>

      <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

<%@ page language="java" import="java.util.*" pageEncoding="utf-8" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
    <meta name="viewport" content="width=decive-width,initial-scale=1.0">
    <title>测试</title>
    <!--import js in bootstrap-->

    <script type="text/javascript" src="../lib/js/jquery/jquery.js"></script>
    <script type="text/javascript" src="../lib/js/bootstrap/bootstrap.min.js"></script>
    <!--import css in bootstrap-->
    <link rel="stylesheet" href="../lib/css/bootstrap.min.css">
    <!--import angularjs-->
    <script type="text/javascript" src="../lib/js/angular/angular.js"></script>
</head>

<body>

<div class="panel panel-primary">
    <div class="panel-heading">
        <div class="panel-title">测试test</div>
    </div>
    <div class="panel-body">
        <div class="row">
            <div class="col-md-12">${user.username},springmvc OKOK</div>
            <div ng-app="" ng-init="old=‘22‘">
                <p>Input how old are you:<input type="text" ng-model="old"></p>
                <p>You wrote: you are {{old}} years old</p>
            </div>
        </div>
    </div>
    <div class="panel-footer">footer:made by zhouzhou</div>
</div>


</body>
</html>

运行后结果:
技术分享

到这里,我5天左右搭出来的框架就在这里了~~

中间遇到了springMVC静态文件被拦截的问题,显示nomaping,正常的view访问都显示了404错误。如何你的DispatcherServlet拦截 * .do这样的URL,就不存在访问不到静态资源的问题。如果你的DispatcherServlet拦截“/”,拦截了所有的请求,同时对 .js,.jpg的访问也就被拦截了。为了可以正常访问静态文件,不要找不到静态文件报404。需要在web.xml中配置:

<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>

总结

经过了几天的痛苦,最起码搭过了7,8遍才搭出来了。我开始都不知道要发布war包,后来才知道要在tomcat中发布war包,才可以运行出来界面。整个过程虽然有过想放弃但是,还是坚持到了最后。学到很多东西,乐在其中。
